Reteaching economics in practice

Reforming economics teaching has been a heated topic of debate since the financial crisis. My personal views on this align closely with The University of Manchester’s Post Crash Economics Society (PCES), who have been calling for a pluralist approach that would rid economics teaching of its neoclassical core, and replace it with a critical study of economic questions and the diverse methods and approaches being taken to understand and answer those questions. The group Reteaching Economics has similar aims. Certainly a focus on empirical methods would be elevated to a core element, as the question of how can we know things is a primary concern to critical analysis. In all such an approach is not an excuse to avoid mathematics, but to embrace a the wide range of mathematical tools in use.

Change like this is a difficult task, and will ask a lot of students and teachers alike. But in my view it is also a difficult task to teach and learn the bland, abstract and often irrelevant economics that fills the undergraduate textbooks today. Even very complex concepts can be reduced into small components with memorable analogies that make them digestible. And if done right, a new approach should trigger more of a desire in students to learn and apply these new concepts and tools.

I have tried to shift my own teaching towards this approach. The purpose of this post is to share an example of taking an existing course, and the various constraints that came with it, and shifting it towards a more critical and pluralist teaching approach.

Last year I taught Managerial Economics and The University of Queensland. The student body were not all economics majors, but were drawn from across the university’s disciplines.

One constraint was the prescribed textbook (which I could not change by the time I began teaching). It contained repeated lessons in applying optimal control problems willy-nilly to possible problems that might face a firm manager. Like how should I profit-maximise when I have two goods that are substitutes?

Solving an equation that relies on knowing the cross-price elasticity between your products is actually not very useful. The important questions are much deeper and more critical, like “How do I know the own-price and cross-price elasticities in real life?” I mean, are firms really just changing prices all the time to check on their elasticities? Or “What is the current price and why was it set at this level?”

So what did I change in the course?

I made sure that before they embarked on the “textbook” concepts that they were given a broader outline of the big ideas that are implicit in the textbook view, yet completely hidden. Like “What do prices do?” And, “If prices allocate resources, why do firms exist?” You can download my first week’s notes here (I make lecture notes a seperate reference document and use lecture slides as a tool to build and explore example problems during class). To see my emphasis on providing a pluralist view, this is one of the exam questions I snuck in.

Which is the most accurate comment on the following statement - “Firms maximise profits”?
A. Always, because by definition they are profit maximisers.
B. Never, as profits do not always accurately reflect long run payoffs.
C. Often, and always in preference to potentially conflicting objectives.
D. Sometimes, but they may achieve this through intermediate objectives.

I also cut short many weeks of textbook regurgitation and replaced it with concepts and tools that don’t fit in the paradigm, but are nevertheless quite useful in practice. For example, I introduced a simple analysis of real options in investment decisions, which captures many of the realities of irreversible firm decisions (here). I also included a week on networks and evolution that introduced some simple models to capture some of the more interesting firm and market dynamics (here), and allowed us to have informed discussions on questions like performance pay for individuals or teams, and revisit the reasons firms exist at all. When I cover information problems, I discuss adverse selection, but also beneficial selection, and look at how the data shows the opposite of what the textbooks predict in Australian health insurance markets.

I also changed the assessment items from almost purely multiple choice and short answer exams, to a mix of some multiple choice, short and long answer questions that allow concepts to be applied to real life situations and data, and an assignment.

The assignment was about a real company facing real changing market conditions. Students were expected to determine the relevant data they needed to collect to complete the parts of the assignment, then find it, then use it (run appropriate regressions), then interpret it, and present it all in a professional way. Some of them told me it was the best assignment they had done in their whole course in terms of actually learning something interesting, and producing something they can be proud of. This was a relief. I had spent a lot of time preparing it.

Some of the economics majors said it was the only assignment they had ever been asked to do! This was quite worrying, but completely in consistent with economics courses globally. The PCES survey showed that a fifth of economics subject have multiple choice questions make up more than 90% of the course grade, and in half of subjects they make up over 50% of the grade. As a general rule, economists are trained to solve equations and answer multiple choice questions.

So what is stopping these changes from happening across the board?

First, few academics maintain the connection with the wider business and public policy community to have a ready supply of topical recent examples where economics can be applied. They are so narrow in their research focus, that when teaching outside this area, they simply conform to the standard textbook.

Second, many academics are trained neoclassical economists only. When my exam draft was reviewed by another academic for errors, they noted that they had never heard of real options, nor the evolutionary and network models in my course. This becomes an even more serious problem in courses where completely wrong models still fill the textbooks, such as the case with the money multiplier. I have had to stand up in class and say “Ignore chapter 19 of the textbook, it is simply wrong.” Some economists are too loyal and “profession proud” to say something like that.

Third, it is a lot of work for staff. For my teaching last year I spent about 18 hours preparing each lecture. This meant that I had new examples to use, new data, and updated readings that applied economic ideas to recent events. For the assignment I also had to research and write my own version of the assignment to make sure I was asking something that was possible to do, and that the data would reveal something that wasn't apparent on the surface (in this case that a firm which is often thought of as being "high end" actually sold inferior goods). When you want to have students research relevant recent real-life examples, this is what you have to do.

Fourth, some students prefer to just get the grade and don't like the ambiguity that a more pluralist approach entails. They have learnt how to study for multiple choice exams, how to solve equations, and so forth. Having to actually think, while being uncertain about how your thinking will go in the assessment, becomes a challenge.

I’d be interested to hear how others have gone about improving their economics teaching to be more critical and pluralist, and what constraints they faced.

Land tax becomes respectable part of tax debate

After decades of political pressure that systematically clawed back state and local government’s ability to tax land, the debate has now swung back to this most efficient of taxes.

Land taxes are apparently a hot topic for debate at the years NSW Labor annual conference.

New sweet-talking Prime Minister Malcolm Turnbull even said the formerly unspeakable words on national television over the weekend (at the 6.30minute minute mark). Though he says while it is a great policy economically, it is politically 11 out of 10 in terms of difficulty. No $hit. When your voter based is dominated by homeowners, and your party made up of the country’s wealthiest landowners, you ain’t got a chance.

Let’s do the hypothetical anyway. How much could be raised from state land taxes?

In NSW just the exemptions to the current 1.6% (2% over 2.5million in value) land tax amount to $700million per year.

In Queensland the exemptions to the current land tax regime cost the state $1.3billion in 2014-15, with the components of the costs of the exemptions summarised in the below image.

Yes, you will see a $23million per year land developers concession - at tax with the exact opposite incentives to efficient tax, reducing the cost of not developing land.

In Victoria land tax concessions are forecast to cost $2.9biliion in the current financial year, amongst a bunch of other concessions that amounted to a total of $4.9billion. See the summary from the budget papers below.

So just in these three east coast states we have about $5billion per year just in land tax exemptions, plus many billions in other exemptions, including on gambling. If we remove the land tax concessions and double the land tax rate to around 4%, these three states could raise another $13billion every year.

But that is just the start of the tax concessions for the nation’s wealthiest.

What about another tax loophole? The capital gains tax exemptions. Treasury estimates it costs the country $56billion per year.

Or discounted taxation on super contributions? There’s another $27billion per year.

There are simply billions lying on the table in obvious tax loopholes for the rich, with land tax exemptions just one of many.

We have seen one big change - saying the words land tax has become acceptable for a politician. Now let’s hope this change starts snowballing, and that states can fight the propaganda of vested interests to use their tax powers more wisely and efficiently.

Die solar roads. Just die.

Humans are quite smart for hairless apes. But sometimes I wonder whether we really do have the edge over our distant cousins.

Here’s an example. Solar roads. For some reason, the most idiotic idea ever still seems to gain popular attention and funding. France is now committing to investment in solar roads.

But, you are thinking, that actually does sound quite interesting and potentially wonderful. Oh, how innovative.

I know right? The urge to jump on board this idea seems irresistible. But that’s our monkey brain doing the thinking. Because when you switch on your rational mind the whole this looks like a big joke.

Our instincts are not good at thinking about a new idea in relation to a particular alternative. It takes conscious rational thinking to realise that for this to be a good idea, we need to think of alternatives to compare it to. Our default is to compare solar roads to no solar investment, hence the urge to think it sounds great.

So here’s an alternative. Solar panels anywhere but roads!

The solar roads concept also implies it is solving a problem that doesn’t exist. In this case, a problem of insufficient space for solar panels. But that is absolutely not a problem. Estimates suggest there are 400sqkms of just residential roofs space in Australia that could accommodate solar panels. More than enough to our total electricity needs, and that ignores the large industrial and commercial spaces available.

Here’s my very brief list of why the idea is stupid.

1. Roads have things on them that block the sun, like cars, people, trees and buildings shading them and so forth. 
2. Roads cannot be angled to efficiently capture sunlight. 
3. Roads get dirty. 
4. Roads need a superstructure above the solar panel that will reduce efficiency. 
5. Building solar roads means expensive excavations and repairs that will block traffic flow. 
6. The technology to do it is rubbish. 

You may have heard that in Amsterdam there is a trial of a solar bike path. I think the title of this article sums up their result “That Fancy New Solar Bike Path In Amsterdam Is Utter Bullshit"

That article says it all.

What about a better alternative? How about building a roof over bikeways covered in solar? This alternative has a few things going for it

1. No excavation 
2. Cheaper 
3. Keeps cyclists dry 
4. Keeps snow off the bike path in cold climates
5. Can be angled to the sun 
6. Is proven technology 
7. Provides shade in hot climates 

Plus more.

And, it has been done before quite successfully.

So please, turn off your monkey brain. And when your friends on social media get excited about solar roads, send them here. Or send them this.

How to get your land rezoned: A QLD story

My previous research looked at favouritism in land rezoning via the Urban Land Development Authority (ULDA) in Queensland. By looking at the characteristics of landowners inside and outside the boundaries of the rezoned areas I was able to show that that main determinant of getting rezoned is not your land's size, or location, or any other planning consideration, but how well-connected the landowner is in a social network of connected elites in Queensland.

So it is interesting to see one of those landowners who missed out (partly) on the favouritism of the ULDA seeking favours from the Logan City Council using exactly the type of textbook methods of influence I uncovered in my previous research.

The project is called Flinders, and it is situated outside the southern boundary of the Greater Flagstone ULDA area (which after a change of government is called a Priority Development Area). When I came across materials for this development proposal I thought it quite unusual; it’s not in a priority area, there are plenty of identical “new town centre” developments planned within a 10km radius, and there seems to be quite a lot of marketing fluff online considering the thing isn’t even approved and probably shouldn’t be according to existing planning controls.

For someone who has spent four years investigating dodgy planning approvals in this area it was a case that seemed quite interesting.

In the image below, from the documents submitted for planning approval, you can see the priority development area (GFPDA) hashed on the right of the blue line. The land owned by Pacific Holding Pty Ltd (applying for the development approval) is in yellow, and they are seeking to approve a massive new township on this whole area (which is currently agricultural). If you want to look up all the details go to the Logan Planning and Development Enquiries page (here), and search for application MCUI - 38 / 2015. It applies to Lots 1, 2, 3, 19, 32, 42, 79, 80, 390 and number 194 Mount Elliot Road, Undullah.

The proponents state in their application that they missed out in being fully within Greater Flagstone Priority Development Area (GFPDA), and are arguing that they should be treated in a similar manner in terms of planning outcomes. They say

The subject part of the Flinders development will provide a logical extension to the GFPDA and will be a key landholding contributing to land supply to accommodate forecast growth in the region. Ultimately it is anticipated that the population of Flinders will be in the order of 50,000 people (32,000 of those will reside on the subject site) with 15,000 permanent jobs created in a range of occupations.

Note the ambit claims of future population. Sure, maybe at some point this century there will be 50,000 people there. But not in the next couple of decades. It’s also lovely to see claims of how well-connected the site is. I drove through there recently. Trust me. It’s not well connected.

In any case there are some more interesting parts of the application which show a textbook effort in gaining political favour, after having missed out on the last round of favours at the ULDA.

Who is this?
Darwin and Michelle King are the children of Philip Cea, a fruit grower who was embroiled in the citrus canker outbreak in 2005, and was claimed to have bypassed quarantine to import fruit trees and vines in 2001. Aside from the fruit business, he has also has built relationships with government, and was part of a 2013 trade mission to China along with a number of other high profile property industry people, including professional lobbyists (some being former politicians), many land developers, and real estate agents.

The relationship building
I found this video of the King’s hosting a one-day development forum about Cities of the Future, which provides a picture of the next generation’s own efforts to build relationships. Invited were various State agencies and local government representatives, planning consultants and property industry organisations. It’s quite interesting to see their investment in relationship-building documented this way.

It’s almost as if the development cannot be justified through regular planning routes based on its own merit.

Some of the names of consultants employed or appearing in the video include, Mike Day from RobertsDay planning consultants, Gavin Johnson and John Harrison from Mortons Urban Solutions. Daniel Parker and Alexander O’Reilly from MacroPlan for the “needs assessment”. Stephen Harrison from iLiv group, who is also Vice President of the industry lobby group the Urban Development Institute of Australia (Qld), is the project director for the Flinders development.

I'm not accusing any of these people of doing anything other than what they are employed to do. But hiring the "right" consultants has always been part of relationship-building, something the King’s have been undertaking with vigour in order to secure their planning approval. Does anyone really think they would have the same chance of success if they only hired consultants who had never dealt with the local council or State government before?

The cover fire of urgent demand
The “Housing and Non-Residential Needs Assessment” submitted as part of their application is quite something. It asserts that when there are 50,000 people living there, than there will be demand for many services and facilities. I’m stunned. But I don’t see anything about where the 50,000 number comes from.

They also try to hitch a ride on the back of the neighbouring Priority Development Area again, this time by stating how much their development will “amplify” all the gains. It’s a real magic pudding story devoid of any realism.

But we know this is all nonsense. Another Priority Development Area, Yarrabilba, which is a very similar urban fringe development, has a 30 year timeframe for their build out to 45,000 residents. With both of these substitute developments competing for buyers and new residents, I expect that it will take half a century or more to get close to building what is proposed.

To be more clear, population growth in the whole of Queensland was 70,540 people in the year to June 2014. What share of Queensland population growth will go to this one development each year? Maybe a percent? So at 700 people per year, that's 71years to build out the development.

So why the urgency? What exactly is the pressing need? Is this just cover fire - a distraction for the public and an legitimate-looking excuse for the council to approve what might otherwise be a nonsense application?

The lies?

On page 44 of their application they commit to

Develop an Innovation Precinct in partnership with Massachusetts Institute of Technology (MIT) and CSIRO.

They also reiterate this on their “Housing and Non-Residential Needs Assessment”, stating

Flinders was a core partner (along with CSIRO) in a submission to the Australian Government earlier this year seeking to establish an Industry Innovation Precinct focused on urban development. Its goal was to provide the opportunity to integrate innovation into existing urban development practices that could create an exemplar sustainable community and be replicated nationwide. It is not apparent whether this program will continue under the LNP, however Pacific International Group has secured Massachusetts Institute of Technology (MIT) and Bond University as innovation partners to build on the work done to date. This may also include a tertiary education facility.

They go on to explain the value of having an MIT facility in the area. That would be quite something. My guess is that they are talking up “inviting someone from MIT to a conference” as some kind of commitment to a remote campus. Again, if the demand for this development exists there, why the need to name drop so outrageously?

Trusts and hiding financial interests
It is common to use trusts and other structures to hide what is going on. Flinders is no exception. Here it’s the Pacific International Development Corporation (PIDC) Trust making the application. The land is owned by Flinders Land Holding Pty Ltd.

As it typical in Australia, knowing exactly who owns what land is often quite tricky. After years of being unable to truly enforce our own tax laws, the Australian Tax Office has now requested from each state 32 years of land ownership records. It remains truly bizarre that land titles and corporate records are not freely available online. Knowing who's who is a business for insiders only.

Weakness of political donations
What I didn’t find is also notable. I didn’t find any records of the Kings, or their various businesses, donating to State politics in the last few years. This is one of the findings I made when studying rezoning in other ULDA areas. Political donations weren’t as useful at gaining favours as being well-connected to insiders.

If my research has merit, and if the King’s continue to build their relationships with property insiders, than I have no doubt they will be granted extremely valuable rezoning gifts soon enough. If only they had been working their relationships this much back in 2005-2008 they might have had their whole property declared inside the Greater Flagstone ULDA (now GFPDA) the first time. 

#ResistCapitalism

My twitter feed has been aroused into fierce anti-capitalist protest. Welcome to 2016 I guess.

This situation gives me chance to flesh out some important points that cannot be made effectively on Twitter.

Resisting power
My view is that the hashtag has arisen out of a resistance not to the capitalist idea of private property ownership in particular, but the exercise of political power under the veil of capitalist ideology (much like the Occupy movement). Bailouts of banks not for people. Money for weapons and war but not public services. Increasing legal protections for the rent-seeking elites, such as extending patent and copyright protections. Removal of the power for workers to organise in their interests. A hollowing out of welfare based on ideology, rather than an extension of it based on our accumulating wealth abel to shared.

But these types of power conflicts arise in all systems eventually. So while the protest is brought together by a common enemy of the current system, many involved have vastly different ideas about what alternative system would better deliver their desired outcomes.

Sclerosis
Mancur Olson spent a career making the point that stable systems begin to break down over time due to infighting over economic rents. That is what we are seeing now, to an elevated extent, in many of the major Western economies. What sort of system do we have that allows the rich to become so insanely wealthy while leaving others poor, homeless, and struggling for find a productive social niche for themselves? The answer is a system suffering from heated internal infighting. My view is that this occurs after a period of stability and a lack of external threats to the existence of the group (i.e. country). You see after a war that it suddenly become easy to distribute wealth to returned soldiers and their families, providing cash allowances, public healthcare and housing. Yet when the war is amongst internal interests, these desirable institutions suffer.

An ecosystem of institutions
What most people want is a set of institutions that allows for private investment and risk taking while ensuring the negative external effects of these activities are limited. They want stable basic services provided in a manner that ensures equitable access, rather than access based on wealth and income. These basic services will obviously expand as nations become wealthier and luxuries become necessities for functioning in the modern world.

Another thing is that some kind of welfare state is essential for maintaining the dynamism of the capitalist part of the economy. Without this cushion against failure, who would risk their life savings on inventing and investing in new products and innovations? Essentially we all want a mixed economy, a level of safety net that reflects the wealth of the country, and basic services provided in an equitable manner. It sounds a lot like the basic economics. Go #MixedEconomy! The main argument is around which institutions can deliver this effectively, given the realities of politics.

The role of economics

Strangely enough, the core of mainstream economic theory assumes that these desirable systems of institutions have already been met. Even more strongly, models that deal with a “representative agent” assume that a government agency is constantly redistributing wealth in the background so that all people are equally wealthy. This then allows the nice results in terms of efficiency to not have implications on equality.

Let me quote from the world’s most popular advanced microeconomics textbook.

The idea behind a social welfare function is that it accurately expresses society’s judgments of how individual utilities have to be compared to produce an ordering of possible social outcomes.
…
Let us now hypothesise that there is a process, a benevolent central authority perhaps, that, for any given prices p, and aggregate wealth level w, redistributes wealth in order to maximise social welfare. (MWG p71)

So why aren’t all economists raging with the Occupy protestors? Or arguing for a massive redistribution of wealth as an immediate first step to social improvement? Has the discipline sold out to the highest bidder? My view is that economists need to stand up and point the finger at sellouts as a first step in cleaning out this unusually influential discipline, and hopefully in the cleanup process ensure that economic advice arriving at the political level does not suffer from conflicts of interest.

Back to access to political power

Such protests boil down to the inability for the vast majority of people to get a fair say in democratic processes. Obviously bailing out private banks is not capitalism. Severely unequal trade agreements are not capitalism. The Wests selective involvement in destroying “democratising” countries with oil, while ignoring atrocities elsewhere in the world. The inability to invest in public goods in the face of ideological push back by vested interests. They're not capitalism. Occupy Wall Street had similar motives against entrenched interests.

A mixed economy, with a fair share of “capitalist” private ownership of property is a great thing. But when the political power of a select few capitalists overwhelms the system to the extent that the other non-capitalist parts of the mixed economic suffer, there are obvious and genuinely satisfying moral grounds for protest.

Minor tweaks

So what simple changes could #ResistCapitalism argue for? Here are some

• Annual taxes on wealth 
• Taxes on inheritance 
• More proportional representation in government 
• An independent watchdog seeking out conflicts of interest in politics and business
• Public investments based on local need, and as a way to support local labour demand

Temporary fixes
Any system will start being gamed as soon as it’s created. We need the general public to continue to be politically active and organised, protesting about particular single policy ideas that could be implemented should the movement gain momentum. Be clear that replacing capitalism does not automatically mean replacing the tendency towards plutocracy or oligarchy.

Still more unpopular economic opinions

I have two recent popular posts on my unpopular economic opinions (here, and here). Over the Christmas break I spent time reading and thinking. Here are some more opinions.

1. Democracy is not part of the recipe for a nation’s success. The historical evidence is pretty overwhelming here. Democracy can be useful to appease competing internal interest AFTER overall stability of the legal and economic system is obtained. Introducing democracy BEFORE this generation-long period of stability is a recipe for instability because there is no reason to trust the ballot box.

We also forget that the word democracy captures a vast array of different political institutions. There is no ‘one democracy’. Indigenous Australia’s could not vote in Queensland until 1965. Women in 1905. The voting age was lowered from 21 to 18 in 1973. Making voting compulsory came back in 1924. All of this democratisation happened after the country was quite politically stable. Not before. This is the empirical trend. The Asian Tigers weren't known as the democratic Tigers.

UPDATE: Yanis Varoukafis makes similar points and more in his TED Talk here.

2. The economics blogosphere reveals that economics is often just a clash over competing metaphysical explanations for a phenomenon. “No it’s not secular stagnation, it’s a savings glut”. For an outsider, it might seem intelligent. But in reality, it is chest-beating about preferred ways to label the residual.

3. Improving economics is not about the mainstream versus the rest. It’s about social scientists being able to communicate big ideas to each other, and about empirical strategies to try an eliminate bad or useless ideas and refine the domains in which particular models may apply. Read Evonomics.

4. The long peace since WWII is a historical anomaly. Expect either a) another war between superpowers in your lifetime, or b) a perpetual skirmish against nominal out-group "enemies" who are mostly fabrications.

5. There is no ‘willing driver shortage’ in our car-based transport system. Robot car driving is not in demand. Also, any economic benefits of replacing the labour of a car driver are even greater for rail and bus transport. Driverless cars do not rescue car-based urban transport from its inherently bad economics. Even Uber is using ‘smart routes’ that look like mini-bus routes.

6. Robots are not coming for our jobs. Why is this a thing? Even if robots are intelligent, they will just be a really advanced tool. Like a modern slave. The owners of robots would see advantages. But if they are so smart, wouldn’t they take over the role of capitalist rather than worker to make the big bucks? Or is it all just nonsense. After all, a monkey can’t own the copyright on their own photo, so I’m sure a robot can’t. Nor can it own the product of its own “labour”. To me the robot commentary it is all made up nonsense that ignores the history of mechanisation and the rise of services.

7. Ageing is bloody brilliant. There is nothing good or bad about population growth. It just is. But a stable population makes per capita economic gains much easier, reduces conflicts over resources and so forth. What makes ageing "bad" in some economic analysis is that we seem to pretend that at arbitrary birthdays people in society go from productive contributors to leaching resources. It’s not so simple.

And seriously, if non-workers we such a major economic problem, we would eliminate private ownership of capital anyway. We can't let those capital owners make an income without working, can we? They would be economically costly, just like old people. 

The bizarre politics of child care policy

The latest news doing the rounds is a “crackdown” on childcare rorting to the tune of $7.7million a week (about $400million a year).

Ah yes, cracking down on the really important big items. Put that corporate tax avoidance to one side. Save the crackdown on political expenses for another day. The big news is here.

Unfortunately the logic at play in this childcare crackdown is absurd.

To consider what is going on we first need to understand that in Australia we have a system of childcare subsidies designed to get mothers into the formal workforce. Yet, with carer to child ratios mandated at 1:6 on average for non-school age children, we should expect that a fair proportion of these working Mums trade home-making for childcare work in order simply to make up the numbers.

If the average additional mother entering the workforce as a result of childcare subsidies has two children, then each additional women entering the workforce has about a one third chance of working in childcare. Essentially the policy requires that for every three Mums entering the workforce there must be one child care worker, giving a net gain in the non-childcare workforce of 2 out of 3.

What this “crackdown” is designed to target is Mums running what are called Family Day Care centres, where they care formally for their quota of 6 children in their own home. Obviously their home must meet various size and safety standards and so forth.

The “loophole” is one where

“… parents who run a family day care receive childcare payments for having their own child in a different day care service at the same time.”

But what is exactly wrong with this? If we go from a world of no formal day care, to one with formal day care at the 1:6 ratio, than we should expect that a third of Mums entering the workforce work in childcare. And their children will also go to childcare so that Mum can work.

Do we hear complaints that staff at formal day child care centres whose children are in care at other formal centres are “rorting the system”? So simply changing the location from “non-house” to “house” means the system is somehow not working as designed.

That’s bogus. The system is designed expressly for this to happen. It was clear and obvious to anyone who has thought about it for five seconds.

This is what happens when you create policy designed to juice the economic statistics by making the informal economy formal.

Meanwhile, the government is expanding child care subsidies to nannies this year with a pilot program covering 10,000 children. For the life of me I can’t understand what the difference is between this and the family day care “rort”. Should we expect that older siblings or cousins becoming nannies all of a sudden. Probably. But what would be wrong with that exactly? The economic effect is exactly as desired.

Humans vs Houses: Australia's perverse tax system

Investment property income beats working
I often joke that my investment property earns more than I do. Thinking more about this led me to the realisation that my investment property has an privileged position in the tax system when compared to a measly old human.

Below I summarise some of the main tax considerations from the perspective of being a human making wages, or from the perspective of being an investment property (the property owner).

After making this comparison, our current system appears to be designed exclusively for the betterment of the property community, rather than the people community. It’s unreal. The whole thing is back to front, with all that green showing investment property to be a clear tax winner.

Let us take a closer look at the marginal effects of a dollar increase in income for a one-income family, with two school-age children earning $100,000. They are an above-median household, and a prime candidate property investor. You know. To secure the children’s future. We’ll call them the ‘Battler’ family, because in Australia if you aren’t on the property ladder, making money is a battle.

An extra dollar in wage income for the Battler family over a year attracts income tax, along with a loss of family tax and medicare benefits that together account for 60c of that extra dollar. So 40c in the pocket. The graph below, from David Plunkett, shows the effective marginal tax rates (EMTR) for this family currently in Australia.

Let us examine the case when the Battler family instead makes their extra dollar from capital gains on their investment property. Using round numbers, they buy a $500,000 home with an annual rental income of $20,000, and annual rates, maintenance and other costs of $6,000. They finance this purchase with an interest only loan attracting a $25,000 annual interest bill.

They make a loss of $11,000 over the year they own the property. Of that loss they are out of pocket only $4,400, because they have reduced their taxable income and avoided $4,000 in tax, and gained $2,200 in family tax and medicare benefits.

After one year they sell with a price after selling costs of $511,001, making $1 net over the year from the property investment project.

It’s a risky way to make $1, compared to getting a rounding-error sized pay rise. But we want to compare dollar-for-dollar the tax incentives for earning wages or earning capital gains though property speculation.

So what did the battlers get out of their $1 gain from property investment? First we factor in the 50% capital gains tax discount because they owned the property for more than a year. So they only need add $6,500.50 of the capital gains to their taxable income. With a 60% EMTR that means they keep $9,100.20 in the hand (the tax-free $6,500.50 half, plus 40% of the remaining $6,500.50).

Subtracting last year’s net loss of $4,400 gives a total net gain of $4,700.20. I summarise how this arises from the benefits tax treatment of both the losses and the gains from investment property in the table below.

With these types of advantages to making your money from lazy capital gains on investment property, rather than working for a living, it is no surprise that we have become a nation of property speculators.

We can also work backwards to see in this example case how much of a loss on property the advantageous tax treatment will cover. To break even after tax all the Battler family need to do is make $4,400 after tax on the sale, which would be situation if the capital gains were $6,286, or a sale price after selling costs of $506,286. Under this situation the property investment has made a loss of $4,714 over the year (an $11,000 income loss and a $6,286 capital gain after 12 months), yet the tax system has bailed out that loss for the family through negative gearing and the capital gains tax exemption. Add another 57c or so to the project income - so it makes a $4,713.43 loss - and you are back to the same net outcome as making an extra dollar through wage income; a 40c gain.

Policy for an even playing field
We can use this example to also see the immediate impact from tax policy changes targeting investment property. If we eliminate the capital gains tax discount and quarantine losses against property incomes, we get a different story, which is in the table below.

Here the $11,000 loss rolls over to be deducted from the future income of the property, in this case the capital gains on sale, making the net capital gain of $1. Because none of this gain is subject to the CGT discount, it all adds to personal income and is taxed at the marginal rate, along with the losses in other welfare benefits. After tax both the $1 from investment property and the $1 from the wage income now provide the same benefit.

It is certainly now time for the government to end these tax concessions for investment property. Raising the GST, the current government’s preferred tax policy, is probably the worst choice in terms of both equity and efficiency compared to the low-hating fruit of removing these property tax advantages which currently cost the budget about $11billion a year. Obviously removing them would change incentives, reduce prices, and so forth, meaning that actual budget gains from their removal will be lower. But even so, the shift of incentives across the economy would be hugely advantageous in terms of both efficiency, and equity, as these tax incentives primarily benefit the wealthy.

Update:
Because many claim that negative gearing is a ‘natural result of the tax system’*, we can leave this alone and simply concentrate on the capital gains tax discount.

In this case, the table below shows how the tax benefits from negative gearing remain, yet the capital gains taxes completely offset the tax benefits from the losses made, resulting in the same net outcome. What this means essentially is that this small part of the tax code provides very perverse incentives for investors to speculate on property, than to earn income from wages.

* To the extent that any tax system is ‘natural’. My view is that you use the system to create incentives for productive activity, whether they appear natural or not.

Brisbane's Queens Wharf is a gift to casino owners

Let's bet on when the consortium entering a deal to build a new casino in Brisbane will go bust.

I will bet straight after the company has paid their well-connected senior staff handsome bonuses, and right before being bailed out (probably implicitly) by the Queensland government. As the project progresses the government will bail out the consortium either voluntarily, because the Ministers and staff involved want to build trust with the consortium, or under duress, because the consortium is going bankrupt with a half-finished major project in the CBD.  

The bailout could be in the form of cash payments. But it could also be hidden in the form of an amended scope of works. Promised investment in new public spaces around the casino will mysteriously shrink as the consortium pleas that these were never part of the deal to be delivered by them. The government will be on the hook for hundreds of millions of dollars right at a time when the budget will be drying up from the downturn of the resources and property boom.

I make this bet because I have looked that the fancy images produced to sell the project to the public, and drawing on my experience in costing large construction projects, I can assure you that adding the costs of all the public works in these images cannot be justified by the casino and hotel returns alone. It just doesn't stack up.

This quote worries me 

The Queensland Government in partnership with the Destination Brisbane Consortium will deliver… 

Public-private partnerships. Notice they didn't say those words explicitly. Because they are dirty words these days as we have come to realise that the public sector simply does not have the skills or the courage to be an equal partner. Such partnerships these days mean that all risk passes to the State while all benefits flow to the private sector partner. 

I remember sitting in a meeting with Queensland Treasury in 2009 where they were trying to get rid of these arrangements from government because they always end up tilting risk towards the government and benefits towards the private sector partners. 

But no worries. Happy to do it for a casino.

If you look at the picture below it’s almost like the government wants to get a casino as close as possible to their offices; to align themselves through proximity to the interests of the casino owners. 

I can’t think of a better way to hand money from the public to selected rich, politically-connected casino owners than this. 

For those still thinking about all the external benefits from a new casino (which is adjacent to an existing casino mind you) maybe think a little harder about the international market for high-rollers. You’ve got all of Asia to choose from. The major cities of the world. Will Brisbane now all of a sudden pop onto your radar because there is a new casino next door to the old one? A very marginal proposition at best.

Crucially, watch as the funding mechanism to capture the value uplift on the site is ignored. Gains in land value will be given away to the consortium from the inevitable government investment in public spaces and access to the area.

This will happen because the rules about paying for infrastructure are especially grey in the case of such major projects (see here, Section 6.0)

Infrastructure delivered in the PDA shall generally be funded from infrastructure charges levied on development within the PDA.
Infrastructure charges will be based on Brisbane City Council's applicable infrastructure charging document for the area or an Infrastructure Agreement.
Infrastructure delivered as part of the development may be eligible for an offset against the infrastructure charges that would otherwise apply.

The last point here is important. What it means in practice is that there is plenty of scope to negotiate that publicly accessible spaces in the casino area count towards public infrastructure, and that these might even be used to offset the standard infrastructure charge obligations under the Brisbane City Council’s plan. We have seen wiggle room like this used successfully before to get out of obligations to contribute to the public realm, with private driveways and car parks being counted as public space contributions in complete contradiction to the planning intention of these requirements. 

Essentially, the government is walking into a deal taking on a huge amount of downside risk and absolutely none of the upside. It is guaranteeing profits to wealthy casino owners in a way that is primarily a transfer to them from the rest of society. This is at a time when government revenues will begin falling, and when the city is already committing to costly projects with little to no return, such as the Kingsford Smith Drive project, where costs are likely to exceed benefits by about $200million.

But it remains possible that when the reality of the construction costs becomes apparent, the whole project might simply be canned come late 2016. 

I have no problem with government investing in public infrastructure and improvements in general, but not with the obvious intention of benefiting a select few at a cost to the rest of us. There are so many public projects out there with high benefit cost ratios waiting to be built in the city, from rail, cycle, pedestrian upgrades to improve connectivity, to the basics like stormwater and flood prevention upgrades, and so forth.

Economic capital is like pornography - you know it when you see it

There are two parts to this blog post. First the important stuff, clarifying the weirdness of capital and the confusion of applying economic concepts in practice. Second is a rant about where the weirdness and confusion comes from, and I point the finger at the intellectual laziness of the economics profession.

Important stuff
Read the below quote. Actually, read it twice. And think about it.

Genuine foreign investment, such as the building of factories and infrastructure, adds to the nation’s productive capacity and employment, and should be encouraged. By contrast, merely transferring ownership of an existing asset to foreign interests is akin to “selling the family jewels”. It does nothing to improve the economy and living standards, and should be discouraged.

This is from a recent post by top economic commentator Leith van Onselen at MacroBusiness. On the surface it makes sense. We want investment in new buildings, machines, infrastructure and equipment. And when foreigners want to makes those investments in Australia, that’s terrific.

But we don’t want to “sell the farm” to pay for it.

The thing is, net foreign investment in productive infrastructure, of machinery, building materials, and so forth of the type that Leith explains adds to our productive capacity, always exactly matches the net sale of domestic assets to foreigners.

The bold terms are crucial, for they reveal the accounting identity at the heart of the matter.

You see, capital account surpluses indicate that a nation sold more assets to foreigners than they bought foreign assets. A capital account surplus is balanced out by a current account deficits, which means that as a nation we imported more goods and services than we exported. Having a current account deficit requires selling assets to foreigners as payment for the net imports of goods and services which contribute to our capital stock.

As I said recently, the term foreign investment is “an idiotic and misleading term for a capital account surplus. It should be called balance of trading assets for goods and services.”

Capital in the external accounts is by definition not physical stuff. It is a set of institutionalised rights. Capital in economics, however, has been hijacked to mean physical stuff, which I show below provides very little guidance for answering important economic questions.

The rant
The blame for this confusion lies squarely with the economics profession. Not only do they routinely confuse the “capital” (K) in their models with capital in the common parlance used to describe funding and asset ownership arrangements, but they also think in terms of a world where there is no distribution or trade in asset ownership; all resource use is directed by a benevolent central planner.

At best capital is like pornography - ‘you know it when you see it’. In Christopher Bliss’s introductory comments to his book Capital Theory he notes

It is a fallacy to suppose that if we have a name for something there must be something, particularly a single something, which that name defines.

The textbooks are no help at all. In one textbook I have, by Frijters, Dulleck and Torgler, all I get is “physical capital includes machines, buildings, roads, harbours airports etc.”

Ricardo arguably began this tradition of capital as stuff stating that

Capital is that part of the wealth of a country which is employed in production, and consists of food, clothing, tools, raw materials, machinery, necessary to give effect to labour.

Or perhaps it was John Stuart Mill

What capital does for production, is to afford the shelter, protection, tools and materials which the work requires, and to feed and otherwise maintain the labourers during the process. These are the services which present labour requires from past, and from the produce of past, labour. Whatever things are destined for this use—destined to supply productive labour with these various prerequisites—are Capital.

Mankiw’s macroeconomics text has a similarly naive and brief definition, stating that capital “... is the set of tools that workers use: the construction worker’s crane, the accountant’s calculator, and this author’s personal computer.” And later, “the capital stock is the quantity of machines and structures available at a given time”.

The fundamental economic elements of capital seem to be:

1. They must be produced physical objects that last a non-zero period of time 
2. During that non-zero period of existence they must be an input into productive activity 

If that’s all there is to it then how can there be any non-capital goods produced? After all, food produced in one period is an input into the sustenance of productive labour in the next period. How can we walk around classifying objects as capital or consumption goods?

Look at the image below. A trained economist would call the bikes on the left consumption goods. But that same economist would turn around and call the ones on the right capital, since they are used as inputs into future production of bike hire services. Yet the ones on the left are also inputs into future cycling services as well! 

Where does that leave the core mainstream economic models? Say, the production function?

The equation below is typically used to introduce the idea of a production function, that say that output (Y) is a function of capital inputs (K) and labour inputs (L) in their strict physical economic definitions.

Y = f(K,L)

Yet if capital is everything except labour, then we can translate this equation to mean

“stuff produced is the product of labouring with other stuff”

Capital becomes merely a residual of inputs after labour (or is that just human capital?).

Once you are indoctrinated into the world of capital as physical objects, there is no where to go to explain deviations from your beliefs except in physical terms. If the model deals with physical stuff, changes in factor payments, wage levels and returns on ‘capital’ (which is quite clearly not physical stuff, since I've never seen a road or machine get paid), or even growth in output, must be the result of some mystical changes in the physical properties of stuff.

To explain these phenomena in this framework one must invoke the idea that objects have some special characteristic of being objects - a technology of objects - that allows them to transmogrify in particular ways that change their physical nature. Computers must compute more computely, and cars must drive more drively for growth to occur. And when these objects become more objecty they are then able to earn a higher ‘factor return’. Better computers bargain for better wages.

Economists are then naturally inclined to look for physical explanations of every social phenomena rather than institutional explanations. Maybe we are having a great stagnation, where objects are somehow unable to transmogrify as successfully anymore. Or maybe we are looking for physical answers to non-physical questions?

Problems with the physical object view arise in estimates of productivity (total factor or labour). The world of physical production is the fantasy world of the neoclassical production function. Some statistician is walking around pretending to measure physical quantities by looking at prices, classifying arbitrarily different objects into a stock of capital, pretending that the world rents every bit of capital from aliens, ignoring almost all the physical capital that is not in corporate accounts (like clouds, oceans, the atmosphere, mineral reserves) and stirring the Excel spreadsheet pot until a single number drops out.

When you read about the fall in Australia’s multi-factor productivity, you should laugh at the incoherence of everyone who pretends to know what it means, and feel sad of those who prescribe their own ideological remedy to the problem of a made up number going the wrong way.

You see, a negative change in multi-factor productivity is a puzzle for the production function view of the world. Does it mean we are so stupid that we combine stuff to make new stuff less effectively than we did last year? Are we getting dumber? Or is our stuff transmogrifying once again, and we are to blame the residual for our woes, and label it with the flavour of the month, like Hicks-Neutral technology shocks or something just as meaningless.

We can then say such profound nonsense as “computers made workers poor”. Okay.

Rant over.

Praise the lord! Recite the Economic scriptures

One feature of economics is its uncanny resemblance to religion. When a complex question arises outside of your narrow field of expertise, like a priest during confession, resort to the scriptures.

This is especially true for economists of a particular political persuasion, who are immune any empirical evidence that conflicts with their scriptures.

And so it is with economist polls. The University of Chicago Booth School of Business started their “experts panel”, which is the place to go if you want to see a bunch of people say that introductory economics textbooks are almost always right.

The image below shows an example. See? They all find the idea of Nash equilibrium a really powerful lens through which to view the world. I don’t. But anyway.

This craze of surveying a panel of economic experts has now reached Australia, with Monash University and the Economics Society of Australia posing tricky questions to our own high priests.

It’s so lovely that we now get our own beautiful ritual of watching the high priests periodically recite the economic scriptures.

Take the latest example. The question asks about the economic consequences of the government changing the rules around penalty rates (wage premiums) that are mandated for Sunday work (along with late night work and a range of other situations).

As you can see, 80% of the panellists agree that reducing the minimum wages for Sundays in a variety of industries will be “good” for employment and production.

From someone who agrees:

This is a bit of Economics 101 that is very likely to work

And another:

For many people, weekends are not what they used to be, and are just another part of the week. Given there would be a willing supply of labour, and a demand for it from those entities that currently close due to higher weekend costs, there should be a market outcome that suits many.

Sounds a lot like reciting the scriptures to me, without much consideration of the context. Basic questions like - Why are there weekends? Why do the wage rules exist in the first place? What non-market outcomes were desired?

But what about the minority? The 6.5% who didn’t recite the scriptures?

I think it will have almost no effect on overall employment, merely shifting activity from Saturday to Sunday. Its main effect will be to reduce the rent-sharing of workers and normalize Sunday as a regular working day, both to the detriment of workers but to the benefit of large employers. It is hence mainly a distributional issue.

And another:

The fact that there is increasing demand for services on Sunday does not imply that workers should be paid less to provide those services. In fact, one would argue that workers should be paid even more.
…
if longer opening hours on Sundays imply that consumers spend more time and money at cafes and restaurants on Sundays, then the volume of business of these shops in weekdays might decline. If this happens, than the net effect on employment becomes even more difficult to predict.

Seems reasonable to me. After all, people generally have the same annual incomes and expenditure regardless of which days of the week they do the spending. And I doubt that Sunday trading is holding back investment in new equipment that would add to the nation's productive capacity. In fact, it may hinder it.

You will notice that each of the economists on the panel has made a career out of showing why naive “econ101 assumptions” don’t apply to their field of expertise. Yet when asked about an issue outside their field, they resort to the scriptures, as if theirs is the only deviation from the textbook case. This is lazy and not at all scientific.

In general, the best way to interpret these surveys is a chance for economists to pledge their allegiance to the econ-tribe, making the whole effort a clear demonstration of economics as religion.

More unpopular economic opinions

My last post on unpopular economic opinions was actually quite popular.

Here are some more.

1. There is no such thing as freedom. Every right has an equal and opposite obligation on the rest of society to accept that right. I want to walk around naked through the city. What type of idiotic freedom-crushing society doesn’t let me do that. Well, pretty much all of them. Because my right to waltz naked comes with the equal and opposite obligation on others to accept naked people wherever they look.



Since this "freedom=obligation identity" is always true, there are limitless examples to draw from.

My right to peaceful enjoyed of my house and property is an obligation on the rest of society not to interrupt me, to sleep in my bed uninvited, to use my kitchen, to camp on my lawn. 


2. Capitalism is successful not because it is efficient or productive. The amount of duplication of basic services, 25 types of toilet paper, the fact that over 30% of food grown is never eaten, and the massive costs invested in advertising and sales suggest that there is a fair bit of fat that could be trimmed in our economic system.

But capitalism is successful because it is inefficient. It has built in redundancy that creates enormous flexibility. A society with one large mechanised bakery that makes the daily bread for everyone might get points for productivity, but it is risky. A mechanical breakdown, natural disaster, or disease outbreak would all bring the total bread supply to a halt. In a society with multiple competing smaller, but less efficient bread-makers, these risks are greatly reduced.

As Rory Sutherland says:

Competition itself is highly inefficient. In my home town, I can buy food from about eight different places; I’m sure this system could be much more ‘efficient’ if Waitrose, M&S and Lidl were forcibly merged into one huge ‘Great Grocery Hall of The People No. 1306’. I am equally confident that after a few initial years of success, the shop would be terrible. 

So when we teach comparative advantage and specialisation as a great insight from economics, we aren't actually talking about markets and the foundation of competition in a capitalist economy, but a central planner's view of efficiency that is highly risky. One of the puzzle of the USSR was that for all it's economy troubles, it often seemed quite economically efficient in terms of the static allocation of resources.

3. Net foreign investment is an idiotic and misleading term for a capital account surplus. It should be called balance of trading assets for goods and services. 


4. Queuing is often a really good allocation mechanism. Congestion is a type of queuing. The study suggesting that serving the last person in a queue first increases efficiency is stupid. 


5. The amount of human organisation that is determined directly by prices and markets can be rounded to zero. When you consider the vast amount of services and goods that could be priced that aren’t, you realise just how small the effect of the price mechanism is on society.



Don’t believe me? Why don’t we have private property rights and markets for:



Roads. Public spaces. Air space. Oceans in all dimensions. Outer space. Mars. Antarctica. Within family production. Crime and criminal organisations. Government departments including within the military. Firm internal trade and services. All sex outside prostitution. All possible genes and animal species. Sunlight. Wind. 



Add in options contracts for all future rights for all these activities as well and we get the feeling that the story that economics of markets and prices plays a tiny role in human organisation and production. I reckon the scope of possible property rights must be thousands (millions?) of times larger than the actual property rights that facilitate priced exchanges that we have in place. 



Not only that, but prices are way too sticky to be performing the function they are suggested to do in economic theory. Coca-cola was 5c a bottle for 70yrs.

As you might have guessed, Ronald Coase is my favourite economic pioneer.


6. Writing off the $1.2 trillion of US student debt would be costless and probably a good way to stimulate the American economy. It would have the same effect of writing off any debt. 



I say it is costless because it is just a transfer from the owner of the debt to the borrower. So although the students in debt are probably above average in terms of their wealth, those who own the debt are probably even wealthier. Hence it would be a redistribution from the super wealthy to moderately wealthy as well as being an economic stimulant as those student whose debts are written off increase spending on goods and services more, relative the owners of the debt. 



The discussion of this topic on a Slate Money podcast earlier this week totally missed this point about this being an asset transfer. 


Missing: Morality and flexibility in economic assessments

I spoke last week at the EDO LawJam about missing elements in the economic analysis of major projects in Queensland, and across Australia.

Assessment of the merits of such projects typically require some kind of cost-benefit analysis. This analysis is intended to take into consideration the vast array of externalities and second round effects of major mines, ports, rail, and other projects, like casinos, subdivisions, and so forth.

One major problem with these assessments is the sheer ambiguity of the requirements, and hence the quite extreme level of discretion in how to undertake the assessment. Project proponents employ economic guns-for-hire who use whichever method of assessment gives the desired answer. Not surprisingly, benefits alway greatly exceed costs.

My fellow speakers in the night - Rod Campbell and Sean Ryan - shared examples of mining companies sourcing bogus economic reports to massively overstate the social benefits of their proposed operations, only to find them thrown out of court during appeal cases. This has lead to some projects having multiple economic reports; the first commissioned to give an outrageous answer, the next to give an answer that might stand up in court.

There is clearly a problem of outrageous flexibility in the regulations when the same company can commission two economic assessments and get two totally different answers to the social costs and benefits of the same project. In one case the net job creation estimate was inflated by 1,000% compared to their second round report, while the value of State royalties was inflated by 1,800% ($22billion compared to $1.2billion).

But this is not an accident. Major mining and property development projects are the playground of politically connected insiders. Take this example of a mine neighbouring NSW Minister for Primary Industries, Lands and Water Niall Blair’s property, which has “this remarkable dogleg around the minister's property by the mine site”.

Political connections get outcomes in this game, and to keep the game going requires considerable flexibility in the assessment regulations.

Apart from this political element, I spoke about two main points.

1. The neglected moral foundation of economic analysis 
2. Ignoring the value of flexibility 

My point about neglected morality is that any estimate of costs and benefit necessarily makes moral judgements about whose costs and benefits are worth considering. Why only humans? Why only Australians? Also, there are hidden moral judgements about the dollar-for-dollar equivalence of cost and benefits affecting different groups of people in different ways. Undertaking economic assessment without acknowledging these foundations is deceptive.

My second point is that major developments, particularly open cut mines, are irreversible commitments. If at some future point in time it turns out that the site is more profitably and socially beneficial for use in agriculture, or some other use (say a solar electricity generation plant), then we cannot change the use from open cut coal mine back to these alternatives.

But if we stick with agriculture, we keep open the option for alternative high-value uses at future points in time. Thus, when comparing the social costs and benefits of a project like a mine, with a baseline alternative of agriculture, we must value the inherent flexibility of agricultural uses to allow for alternative future uses of the site.

Unpopular economic opinions

1. School is mostly about indoctrination into the national identity. It is also about child care, and for older children, about keeping them out of the labour force. If we were honest we could talk about education policy with this in mind, though no one does (okay, there are some exceptions).

2. Gossip is a fantastic coordination device, allowing us to find like-minded others by bitching about particular issues or other people. The underlying idea here is that “my enemy’s enemy is my friend”, so if someone wants to have a good bitch, they are likely to be similar to you. Could be one factor in homophily observed in social networks. Again, rarely discussed.

3. The tax debate is 99% about distribution, 1% about growth. Don’t let economists fool you with their models that they don’t even pretend capture real phenomena. When they say lower corporate taxes increase growth they are modelling a world without assets where all profits are devoted to new investments in capital equipment.

4. Microeconomics is no more scientific than macroeconomics, particularly when it comes to theory. When people say there is progress in micro they mean in applied psychology, where experiments are widely used, and in empirical work where new data is helping to answer localised questions.

Most microeconomics though is still about markets, where aggregation of individuals is still a huge problem - it’s just a different level of macro.

5. Farmers are one of the wealthiest groups in the country and we shouldn’t prop up their businesses or lifestyles (see chart below). They are not charities and will jack up prices when they can. We can protect food production as an industry by protecting the degradation of the land from incompatible and irreversible uses like mining, housing developments and so forth. But some farm businesses will go broke from time to time and that is not a problem. We also are a massive food exporter, so there is really no “Australian food security” argument. 

6. Speaking of food security, we really overlook the main cause of malnourishment is poverty, not a lack of food production in the aggregate. Making poor people richer by taking from the top few percent of wealthiest and giving to the bottom 20% of the world would solve food security, amongst many other social ills.

7. Redistribution of global wealth is clearly the most obvious policy for a utilitarian. Bloody obvious.

8. Open borders to me seems like a way to pretend to be serious about global poverty and inequality. It allows supporters to pretend that the borders of private property within a nation are moral, yet the borders between nations are not. Somehow if I am denied, through accident of birth, to make a living from my share of the land in my own country, this is a radically different thing to Alex Tabarrok’s view, where he asks “How can it be moral that through the mere accident of birth some people are imprisoned in countries where their political or geographic institutions prevent them from making a living?”

As I have said before, even the wildest proponents of open borders agree that

“…open borders could not on its own eliminate poverty and that international migration could only help the relatively better off among the global poor”

Then what is it really for?

Two-child China, and population ageing myths

China abandoned its one-child policy yesterday. Just about everything I’ve read since explains that this policy shift is a result of fears about dependency ratios; the ratio of the number of non-working age people in the population (children and the elderly) to the number of working age people. As shown in the chart below, China, like most countries, is seeing the start of an uptick in this ratio due to an ageing population.

But the simple fact is that increasing fertility rates isn’t a solution to this problem.

The reason population growth doesn’t solve this problem is that a growing population relies on

1. more children, and hence a higher youth dependency ratio, or
2. more immigrants, who both reproduce (more children) and become elderly themselves. 

The only way population growth can ‘solve’ the age dependency problem is if the growth rate itself continues to grow in a grand human Ponzi scheme.

To make this point clear I have poached the data from a great study way back in 1999 by Peter McDonald and Rebecca Kippen. They simulate a number of Australian population scenarios that represent some of the political views at the time ranging from Harry Recher’s view of a one-child policy coupled with zero immigration, to Tim Flannery’s view that a sustainable long-term population target is 12 million, to Jeff Kennett’s view that immigration should be ratcheted up as far as necessary to maintain a constant dependency ratio.

I show in the graph below the dependency ratio[1] based on the various population projections in their simulations (final populations in 2100 are in brackets).

A few things should be noted.

First, the lowest population projection, the Recher model, gets Australia’s population to 5 million by the end of the century and reaches a peak dependency ratio (DR) of about 2.2. The highest population projection, the Kennett immigration solution, reaches a population of 929.5 million (yes, a billion) in 2100, relying on a population growth rate of over 4% to keep the DR at its 1998 level of about 0.7.

In between these two extremes we have population paths that lead to populations between 12 and 50 million by the end of the century, all of which result in a DR between 1 and 1.5 by this measure.

But here’s the thing. That 0.5 difference in the DR between the radically high and low population projections, can be totally offset by changing the retirement age by just two years - shifting the population at age 65 and 66 from dependent to working age.

At the moment the Australia pension age is shifting two years - from age 65 to 67. If social norms of employment change to accompany this, any ageing problem is already solved.

In short, what seem like insurmountable demographic shifts are actually relatively slow and minor changes in economic terms. Not only does a declining youth dependency ratio offset much of the increase in the age-dependency ratio, but from the perspective of the economy as a whole the potential costs of ageing are minor compared the economic and environmental costs associated with rapid population growth necessary to suppress this ratio.

[1] In these scenarios the dependency ratio is weighted so that a child accounts for 3/4 of a person, and a retired older person (above age 60) accounts for 5/4 of a person.

Queensland will ignore better planning

I wrote a submission during the consultation on reforms to the Queensland planning system. As you are probably aware, my research in this area focusses mostly on teasing out statistically the amount of favouritism happening in high value rezoning decisions.

My submission also focuses on the scope within the proposed Planning Bill for continued favouritism. But I also raise the point that we should enshrine at the highest level that governments of all levels, from Councils upwards, be able to capture the land value created by their planning decisions. As it stands the Bill suggests the opposite should be the case - that Councils are liable for compensation should they downgrade the value of land uses at a location (subject to the land being currently used for that purpose).

In no other area of government do we give away property rights for free, so often. It's a multi-billion dollar annual ritual of gift-giving from the public to politicly-connected landowners.

If you want to listen to a terrific podcast covering the types of mechanisms available to recover value gains from government policy I recommend last week’s Renegade Economist episode, which is the source of the below image as well.

Explaining everything explains nothing: Economics

The below comic probably hits a little close to home for most economists. Poking fun of economists’ naive attachment to their particular brand of rationality, and it’s immense body of hidden assumptions, usually gains responses that are merely signals of tribal loyalties and ignore the substance of the critique.

My colleague Vera te Velde made an improvement on the comic which is also included below, and my reading is that she wants to gain loyalty from the tribe more than defend rationality assumptions in economic models.

While it is certainly true that her improvement is consistent with core economic theories, it really highlights in my mind that these theories are essentially vacuous if they can explain anything and everything imaginable.

In response to the ability of other economists to fit everything within their model (meaning nothing can be excluded), simply because of creatively reversing out a set of preferences that explain the observed behaviour (or as Vera concludes De gustibus non eat disputandum), I wrote

There was simply no phenomena he could not explain with his beloved utility theory. But if the theory explains everything imaginable, then it predicts nothing. I resolved that the theory as it stands, in the revealed preference form, was not falsifiable, though he didn’t seem to understand why that would matter.  

Sure, humans often make calculated decisions, but the more I learn about the nexus between individual behaviour and how we behave in groups, the more I see very little value in rational-individualist views of economic systems that see all behaviour arising from God-given personal tastes. Without acknowledging the necessity of group-coordination mechanisms intrinsic in our behaviour, we are missing the main story.
