Intuition in economics can't replace reason

One thing you will notice early on about economics is the overuse of the term intuition. Typically the term is used like this — “Let me give you the intuition behind this model”. Or something.

Let’s take a look at the common definition of intuition for starters. Google tells us that intuition is "the ability to understand something instinctively, without the need for conscious reasoning."

When you think about it—when you reason—you quickly see that intuition is a way to NOT reason. Instead, it is a way to latch onto ideas that support pre-existing beliefs.

When I hear a seminar presenter say “let me give you some intuition,” I now translate it in my mind as “let me align my theory with your beliefs so you will have trouble disagreeing with me regardless of the strength of my reasoning and the evidence I present."

I find the elevation of economic intuition to a skill in itself to be very unscientific.

In physics, for example, I see people discussing intuition as either experience with certain types of mathematics (you internalise the steps of mathematical logic), or as experience in the physical world—of taking one’s lived experiment and applying what are now intuitive results to problems. You know a lever works because you have used levers many times. The results do not contradict your lifetime of personal trial and error and therefore the result is intuitive. But from my experience, this is not what economists mean.

Duncan Watts describes much better how intuition pervades social sciences and stifles scientific advancement, particularly in economics.

Part of the problem is also that social scientists, like everyone else, participate in social life and so feel as if they can understand why people do what they do simply by thinking about it. It is not surprising, therefore, that many social scientific explanations suffer from the same weaknesses—ex post facto assertions of rationality, representative individuals, special people, and correlation substituting for causation—that pervade our commonsense explanations as well.

In many ways, intuition from experience should be irrelevant to individuals analysing complex systems from within them, especially since the properties of the whole are typically unrelated to the properties of individual parts. 

With so much emphasis on intuition over reason, it is no wonder that a fair portion of economic debate has not progressed in 140 years.

Spartan Morality

I want to show how the morality on display in the movie 300, in which babies are cast into a chasm for minor deformities or other weaknesses and illnesses, is easily compatible with utilitarian logic. In doing so I hope to show that utilitarianism provides completely insufficient scaffolding around moral reasoning to eliminate almost any policy, norm or cultural practice you desire.

I was motivated to write this post after discussions were stoked by my take on the moral foundations of economics, particularly in relation to health policy. Why it is optimal from a utilitarian point of view to allocate medical resources to the young rather than the old? While my personal view is that in our current social and political environment this is probably appropriate, it is by no means a superior position by utilitarian reasoning, and certainly there remains debate about such welfare foundations. 

To get this brief analysis started, here is a Wikipedia excerpt about life in Sparta.

Shortly after birth, a mother would bathe her child in wine to see whether the child was strong. If the child survived it was brought before the Gerousia by the child's father. The Gerousia then decided whether it was to be reared or not.
It is commonly stated that if they considered it "puny and deformed", the baby was thrown into a chasm on Mount Taygetos known euphemistically as the Apothetae. This was, in effect, a primitive form of eugenics.
Sparta is often portrayed as being unique in this matter, however there is considerable evidence that the killing of unwanted children was practiced in other Greek regions, including Athens.

Here’s some basic utilitarian rationale for the ‘Spartan morality’ of disposing of sick children. It could rely on any of the following propositions or assumptions.

1. People with life-long physical disabilities or other chronic illness have lower utility than those without.
2. Disposing of sick children brings forwards births of non-sick children because of replacement reproductive effort.
3. There is relatively low utility loss from mothers and family of disposing of their sick child.
4. The existence of ill people reduces the utility of their carers.
5. The reduced ability to contribute to productive activity of the disabled and their carers (and medical professionals) reduces the utility of others in society.

In fact, we need not even invoke propositions three to five in order for Spartan morality to be utilitarian, since the first two clearly show that infanticide of the sick, “puny and deformed”, would be a straight substitute of one lifetime of low utility for one lifetime of high utility, increasing aggregate welfare.

And that’s just about all you need. 

I hope that this challenges your faith in the objectiveness of economic reason. As Joan Robinson would say, utility is a meta-physical construct—its existence rests on circular reasoning, requiring it to be defined in terms of itself. 

Similar utilitarian reasoning could be applied to the subjects of gay marriage, slavery, or other such social practices to support any desired outcome.

We shouldn’t feel helpless in the absence of an objective method of social reasoning. We should feel freed from its shackles to debate our underlying moral values, and why they are appropriate for our societies, given our histories and culture. 

Applying utilitarianism means you can support mutually contradictory ends and means. You can end up at the repugnant conclusion, or justify slavery to a 'utility monster'. Or if you take an average  principle of utilitarianism, you can get to the point of justifying killing disabled children by appeal to Spartan morality. Or, as we deem currently acceptable, arrive at the point where we should allocate scarce medical resources to children above the elderly in accordance to ‘need’. 

There is no absolute reference point in utilitarianism. It is always applied with reference to current norms, customs and practices and can evolve to support different conclusions as society evolves.

17 million Reasons Rent Control is Efficient

The case of Herbert Sukenik being paid $17 million in 2005 to leave his rent-controlled NYC apartment has been receiving a great deal of attention online recently. 

At the risk of perpetuating the brilliant viral marketing campaign for Michael Gross’ new book, which is, in fact, the source of the story, I want to make a brief comment about it to counter some of the bizarre, emotional, and inconsistent reactions I have seen.

A short version of the story is that billionaire developers Arthur and William Zeckendorf paid $401million for the Mayflower Hotel adjacent to Central Park, planning to turn the site into 202 super-luxury apartments.

The building was occupied by many long-term tenants under New York’s rent-control laws. This meant that tenants could only be evicted upon mutual agreement, which in turn led to the new owners offering attractive lump-sum payments to tenants for them to leave the building. While most tenants accepted offers ranging from $650,000 to $1 million, the final tenant held out for an astonishing $17 million lump-sum payment, in addition to the developers offering him another apartment to live in for the rest of his life for a peppercorn rent of $1 per month.

To me the most astounding part of the story has been the reaction by the press and social media, which has been of outrage over the injustices of rent control - that for some reason poor old Sukendik didn’t deserve the money.

There have also been cries of rent-control hindering development - that somehow rent-control is ‘inefficient’.

This is absolutely wrong. Wrong, wrong wrong.

First, almost everyone has ignored the key fact that a developer buying the building knowing that rent-controlled tenants are occupying it should have expected these expenses and subtracted them from the purchase price. Thus, the tenants win at the expense of the previous building owner. The developer does not lose unless some unexpected legal loophole was exploited (which doesn't appear to be the case) - it is merely that the economic rent was shared between the previous owner and the previous tenant.

It is therefore not any less efficient than in the absence of rent control. No one sees the previous building owner holding out for $401million as inefficient, yet it is exactly the same dynamic at play. 

The second point routinely ignored is that rent control describes a general set of rules about renting. That the NY set of rules allows this to happen doesn't mean that another set of rent-control rules could be implemented that had mechanisms for relocation and prescribed methods for calculating compensation payments to tenants. After all, in the freehold world there are generally accepted methods for compensation for landowners upon compulsory acquisition by a government authority.

Third, if Sukenik owned his apartment in freehold he would have had the same power to hold out and extract this price from the developer. This happens routinely in Australia and elsewhere when strata-titled buildings are redeveloped. The last hold out seller extracts a massive payout. Yet we see nothing at all wrong with that because they have ‘the right’ to do it. Yet under a different set of laws, tenants could also have such rights, which they did in this case. 

What really surprises me is that almost everyone who has written a reaction to the incident seems to fall on the side of the developer. If the developer had kicked out the tenant for $10,000 it wouldn't be news, but it would have been equivalent to 'Developer screws tenant of their rightful $17million compensation’.

Wrong lesson from Adam Smith's pin factory

We commonly use stories to teach new ideas, but all too often end up taking the wrong lessons from them. My favourite example is the Coase theorem. Economics textbooks describe theorem as saying that it doesn’t matter where you place the liability for pollution, because in a world of zero transaction costs the right to pollute will end up in the hands that value is most. This is the exact opposite of the point Coase made. As Deidre McCloskey wrote,

Economists have gotten the “theorem” wrong; in fact, backwards
…
Coase’s actual point, the core of a Coasean economics, was to note what happens in the many important cases in which transactions costs cannot be neglected. If the situation does have high transactions costs, then it does matter where the liability for pollution is placed.

I was alerted to another example in Joan Robinson’s long forgotten textbook. In it she dismisses the division of labour as a primary factor in the great surge in productivity of the industrial revolution, noting that this is the wrong lesson to take from Adam Smith’s pin factory story.

First let me recount the relevant part of Smith’s writing where he describes the productivity boon enabled by the division of labour.

To take an example, therefore, from a very trifling manufacture; but one in which the division of labour has been very often taken notice of, the trade of the pin-maker; a workman not educated to this business (which the division of labour has rendered a distinct trade), nor acquainted with the use of the machinery employed in it (to the invention of which the same division of labour has probably given occasion), could scarce, perhaps, with his utmost industry, make one pin in a day, and certainly could not make twenty.  

But in the way in which this business is now carried on, not only the whole work is a peculiar trade, but it is divided into a number of branches, of which the greater part are likewise peculiar trades. One man draws out the wire, another straights it, a third cuts it, a fourth points it, a fifth grinds it at the top for receiving the head; to make the head requires two or three distinct operations; to put it on, is a peculiar business, to whiten the pins is another; it is even a trade by itself to put them into the paper; and the important business of making a pin is, in this manner, divided into about eighteen distinct operations, which, in some manufactories, are all performed by distinct hands, though in others the same man will sometimes perform two or three of them.  

I have seen a small manufactory of this kind where ten men only were employed, and where some of them consequently performed two or three distinct operations. But though they were very poor, and therefore but indifferently accommodated with the necessary machinery, they could, when they exerted themselves, make among them about twelve pounds of pins in a day.  

There are in a pound upwards of four thousand pins of a middling size. Those ten persons, therefore, could make among them upwards of forty-eight thousand pins in a day. Each person, therefore, making a tenth part of forty-eight thousand pins, might be considered as making four thousand eight hundred pins in a day.  

But if they had all wrought separately and independently, and without any of them having been educated to this peculiar business, they certainly could not each of them have made twenty, perhaps not one pin in a day; that is, certainly, not the two hundred and fortieth, perhaps not the four thousand eight hundredth part of what they are at present capable of performing, in consequence of a proper division and combination of their different operations.

This insight has attracted so many followers and is so embedded in economic thinking, that it was quite a shock for me to see it dismissed. Robinson merely states that people can equally divide their own labour across different tasks through time and thus Smith is incorrect in attributing the productivity of the pin factory to the division of labour.

The 18 distinct operations Smith recounts could just as easily be conducted by the same labourer on 18 different days to create the same output per person over an 18 day period as in the case where labour is divided between workers.

I’ll be honest. Dismissing one of the key elements of accepted economic theory in a single sentence is bold. But again, Robinson had a lot to get through in a short book.

So what is the real lesson? To me the lesson of productivity is not about division of labour, but of capital accumulation. 

Smith suggested it was the division of labour that had ‘given occasion’ to the invention of machinery. But this gets causality backwards; it is the new tools and production techniques that allowed both the division of labour and the great increase in efficiency. 

Imagine that each on the 18 separate tasks could be achieved more efficiently with 18 different new tools. Drawing the wire used a particular apparatus, straightening another, and cutting yet another, and so on.

For the individual labourer to be equally efficient as the factories of the time, each labourer would need 18 different tools that each sat idle for 17/18ths of the time. Thus it is the search for returns on the investment in new tools and equipment that allowed for both the observed division of labour and the radical increase in productivity.

You might interject that if 18 labourers joined together they could each buy a single different tool and simply share their own tools on the off days, that they would be equally efficient as a group. But in fact, they would simply be a factory, with the only difference to Smith’s example that workers owned all the capital.

Thus it is capital investment that leads to larger firms, internal coordination via division of labour, and increases in productivity. That is the real lesson of Smith’s pin factory.

Are Australian universities just not good enough?

The reserved and mild-mannered American Canadian law Professor James Allan, who works at an under-performing Australian university, has recently written a long tirade against the bureaucratisation of higher education in Australia.

While it contains a few home truths which need public acknowledgement - like the centralisation of decision-making and the power of university executives to make inappropriate rules, and also set their own pay - it also misses important context, and offers personal biases and anecdotes instead evidence and constructive suggestions for improvements.

I want to respond here to that article. First let me attempt to summarise Allan’s points about what is wrong with Australian universities.

• University administrators seem to value research grants as outputs rather than inputs
• Bureaucratic decisions at universities are quite centralised
• Students work and study, meaning they want lectures recorded and don’t want to do extra reading
• Students don’t travel to other cities to study
• University ranking tables are a sham, and Australian universities are not performing as well as these tables make out

However Allan doesn’t actually explain what a suitable output performance measure should be for a university. The most we get is this

In Canadian law schools (and US ones, and UK ones) you are expected to be working on your degree full-time. You are expected to do lots of reading. You are expected to think. You are expected to pursue things on your own. You are not expected to schedule classes all on two days of the week so you can work the other three. Or tell your professor that you can’t do something because it conflicts with work. Or be so tired that you do as little reading as you can get away with. 

Yet that is now standard practice in Australia. I can still, just, get away with refusing to record any of my lectures and so insist that students come (or not, since as adults it is up to them, but if not they are on their own). But the university administration detests that position and is making it harder and harder to take. As I came to Australia already with a chair I can ignore the students who get infuriated about this practice of mine in their course evaluations. But no junior academic wanting to be promoted can do so. It is no exaggeration to say that the incentives are slanted heavily in favour of caving in, of spoon-feeding students, of recording all lectures for viewing from home (with much reduced class attendance as a result)—anything to facilitate the job commitment of the supposedly full-time undergraduate. 

The flip-side of this situation is that the demands on students (even at our Group of Eight universities) are noticeably below what they are in good Canadian and UK and US universities. As for a serious Ivy League or Oxbridge undergraduate education, well, we are not in the same league as those institutions because we demand so little of our students.

Australian universities are not good enough, apparently, because students need to read more, and think, and pursue things on their own. 

He also makes a personal judgement that what you learn at university must be superior to the skills you learn at work, or that working and earning a living is not ‘pursuing things on your own’. That doesn’t really sound like a typical Australian attitude to me. My personal experience in economics is that a degree gets you in the door, then it is all down to experience. Working while studying, especially in your chosen field, is quite advantageous.

But he really doesn’t elaborate any further. Is university performance measured by research output? Is it measured by revenue? If so, he doesn’t have much of a case against the administrative bias towards academics who generate research grants.

Or is it the number of peer reviewed journal articles? If so, is it quantity or quality? Who will judge quality? Is it student numbers per academic? Or is it student quality? Who will assess that? Or do we judge performance on the gut feel of visiting academics with their own personal biases?

I don’t want to sound harsh, but for a senior academic writing about the underperformance of Australian universities, a little note about what underperformance really means, framed within the role of universities within society, would be nice. He signals that it should be research output, noting that people

…could see the difference between judging people based on what they wrote and produced versus one that judged them based largely on winning as many grants as possible.

but fails to return to how this measure fits into his picture of a competitive university system.

Whinging about the rules doesn’t really help. It is like an Apple employee coming into the company and saying they have a lot of centralised decision-making and that engineers were slugged with bureaucratic tasks, such as getting central approvals to spend money on new equipment. Whereas at their last job they could do as they please.

Sure, from the employee perspective this seems like a horrible system to work in. But any outsider assessing the performance of the company as a whole would feel it is worth it. That’s because we have an agreed measure of what company performance is. For universities we don’t, and that is usually the recipe for a growing bureaucracy.

Allan lays some of the blame at a lack of competition, perhaps due to some cultural norm of families not sending their sons and daughters interstate to the ‘best’ university in their field. Apparently this lack of competition means that universities can slack off and amuse themselves with ever more burdensome central rule-making and ever-greater executive pay.

Allan writes

In this sense, Australia and its universities are at a disadvantage. Imagine what would happen if parents were as likely to send their kids to Melbourne University as to Sydney University or the University of Queensland or Australian National University, and the deciding factors came down to what the universities had to offer, say in terms of class sizes or contact with professors or the “undergraduate experience”.

There are two problems with this point. First, is that the universities are full of international students. Outside of law especially. Surely these students are discerning about their university choice and hence provide a great deal of competitive pressure. According to the ABS 22% of students at university in Australia are international students, while at some universities that figure is over 40%. Monash and Melbourne universities seem to be competing quite fiercely, with Melbourne experimenting with student offerings at great risk.

Second, the central rules that Allan hates so much are just as much the result of competitive forces, than on the lack of such forces; of trying to attract students by ensuring the get the easiest path through their study. We’ve seen the gimmicks about giving new student iPads. Allan mentions the imposition of consistent marking systems, PhD criteria for lecturing positions, timing of student evaluations; all of these are about managing university-wide quality in order to assure new students of what they will be getting. Haven’t you seen advertisements?

This is what happens with competition for students (customers), and students mean revenue. If you want universities run competitively like private businesses, you must expect that they will measure their success in similar ways.

So where does research output fit into his competitive picture? It certainly doesn't raise revenues, and most undergraduates, the customers of universities, wouldn’t have a clue about their school’s research anyway.

Regarding the lack of travel to university, if I can sum up the Australian view very roughly, it is that university is more like advanced vocational training. Degrees that used to be provided by technical colleges are now integrated into universities. Students don’t travel because their local university usually maintains standards high enough to get them into their chosen field. Why travel if you can be assured of equally good local training? After all, once you are in the door, your experience counts much more than your degree in most fields.

He writes

When I try to point out the advantages of sending one’s kids away to university here in Australia I am generally met with blank stares of incredulity.

But of course, he didn’t mention any of those advantages in his article. Could it be that there really aren’t many? Or is he saying that Australians are just too stupid to see them?

Which leads to the more entrenched problem. The competition that drives student selection and travel for study in the US and the UK is the result of monopoly power of universities so that students must compete rather than universities. And this competition between students is also driven from a higher level. Reputation and insider connections within top universities to political and corporate elites means the payoff to getting into those universities is much higher. A degree at Princeton or Harvard is a meal ticket with a value far higher than cost of tuition itself. This not only means that students want to travel to get in to these universities, but that they (and their parents) are willing to pay through the nose for it as well. Here’s just one example of the political connections a degree at Oxford brings.

In Australia we don’t have that ‘boys club’ mentality to such an extent, especially not in most degrees. Having a teaching degree from QUT doesn’t open doors at Goldman Sachs, unlike a finance degree from MIT.

While I am sure Allan feels much better getting this all off his chest, I can’t help but think he has missed the important points to focus on his personal gripes. He overlooks exactly why Australian universities aren’t good enough, and then appeals to competition as some magical remedy to all organisational problems like some evangelical Chicago economist. Lastly, his suggestions for improving the situations include a bunch of central administrative tools!

One of his suggestions, the publication of remuneration of the highest paid employees, is generally already complied with in the annual financial accounts, where executive pay is itemised (here’s UQ, here’s QUT). But of course, executive pay exploding is not limited to universities. It is a general problem of power that competition alone does not solve.

Another suggestion is to publish the ratio of academic to non-academic staff, which is essentially a meaningless ratio because it absolutely depends on the tasks each staff is responsible for. If administrative staff are freeing up time for academics, then that is a good thing. I could imagine these suggestions being implemented and a future version of Professor Allan writing another article deriding them!

He suggests scrapping the ARC grant system, but makes no suggestion of alternative funding allocation mechanisms, as if by magic money will find worthy researchers. I agree the system is poor, but we need to be discussing better alternatives. Why didn’t Allan tell us a bit about the funding systems in those hot-shot universities he so reveres?

When push comes to shove Allan goes for the practical over the ideological, which is a good thing. But it leaves you wondering what the point of all those words really were. Will they merely be interpreted as at the ravings of a sheltered and entitled academic? We have quite enough of that already.

Wages share and investment

Kieran Latty produced this chart on wages share and investment share in OECD countries. If we take this at face value it implies the existence of a wage share that maximises investment - which in the long run is what makes us wealthier. 

To me this seemed a little too neat. Economists love the inverted U-shape relationship, or concave relationships in general, because it implies the existence of some kind of equilibrium - just set labour share correctly and you will maximise investment. Or something like that.

It turns out to produce the ‘inverted U-shape’ curve Latty used a time fixed effect and a non-linear estimator on data from AMECO. While this may be somewhat normal in the literature on this topic - for such reasons as removing the effects of international business cycles and to control for any secular trend in international growth rates - ultimately these model choices fundamentally determine the results. Like most observational data from complex systems, we are applying models as mere plausible stories, with no objective criteria for assessing their validity.

Often the details (including the outliers) in these types of international comparisons reveal much more of the story than the general trends. To satisfy my curiosity I constructed a similar chart from OECD and World Bank data.

Below is the scatterplot of my sample (you will notice the chart is animated to show country data connected through time) . Eyeballing the data there seems to be no general time-independent inverted U-shape. This is confirmed by regressions on the sample without controls, and indeed, with a quadratic specification we find a positive coefficient on the squared term.

 

Notice that each country seems to occupy a distinct section of the chart. Such divergence between countries should be of great interest to macroeconomists. In my smaller sample below Japan has consistently high labour share and investment share, while New Zealand is consistently low on both measures. Then we have the US and UK with consistently low investment accompanying a rather high labour share. 

My expectation is that a high labour share of income would result in greater investment share, if only because owners of capital would have greater incentives to invest and innovate in order to gain a return, rather than simply hold existing assets. Who knows whether this is the case at all. But it’s my current speculation.

What is, for me, more fascinating in this data is the trend over time. We know that the labour share of national income has been falling in most countries since the 1970s. We can see that trend, along with short-term cycles, in the animated chart below that tracks my six country sample since 1970. 

In broad terms the maturing nature of these economies may mean that such a downward trend in labour share is naturally expected. Or it could be that policy choices for the past four decades have directed national income towards owners of capital, which resulted in lower investment in some cases but not others. The answer still seems completely unclear. If you want more analysis, you can read the Productivity Commissions recent work on the topic. 

Like many macroeconomic curiosities, the relationship between wage share and investment is a puzzle unlikely to find a satisfactory conclusion any time soon. 

What does affordable housing mean?

In my submission to the Senate Inquiry on Housing Affordability I wrote the following

Home ownership and reducing housing costs are not necessarily related policy goals. Housing can be cheap with extremely low rates of home ownership, and expensive with high rates of ownership. Clarity about what housing affordability means as a social policy goal is necessary.

There is usually an implicit stance in the housing affordability debate in Australia that a high rate of home ownership is a desirable policy goal. For some reason, a renting society is frowned upon. I put this down to tradition.

In Switzerland and Germany for example, around 60% of households rent. In Denmark and Austria it is around 50%. In Australia 30% of households rent.

We must remember that affordability of buying homes is not the same as making housing cheaper. Making housing cheaper means focussing on rental prices and their share of household income. If rents fell by 25% but prices didn’t, surely we would say housing has become more affordable. And vice-versa, if home prices increase 25% but rents were flat, we should say that housing has become less affordable.

A home is a financial asset that produces a place to live. Why do we care about owning the financial asset that produces our housing, but we don’t care about owning the assets used to produce our food, clothing and other goods? No one ever talks about a BHP share affordability problem!

The exact meaning of affordable housing is a crucial question to consider before any constructive housing policy can be developed.

Some may argue home ownership is about security. Home owners can put down roots because they know they won’t be evicted by a greedy landlord. But security of tenure can equally apply to rental housing, as it does in many countries. We just choose not enact the regulation to enable this to happen. Maybe readers have other reasons that home ownership is socially desirable.

For my part, I believe it is actually counterproductive to tackle housing affordability by encouraging greater home ownership.

Here’s why.

High home-ownership rates imply that most of the electorate has a financial interest in keeping prices high. This implies an interest in keeping rents high in order to maintain those prices. Thus, the interests of the home owner and the investor are aligned against the interests of the renter. 

When the bargaining power of renters is curtailed it merely enables investors to extract the full share of rents - that is, they are able to charge the maximum that renters are willing to pay. Any reduction in rents is merely a transfer of wealth from investors and home owners to renters.

With a higher proportion of rental households governments would be forced to improve conditions for tenants, and by doing so, increase their bargaining power.

Buying a home in Australia currently costs between 1.5 and 2 times more than renting, meaning that few rental households have an outside option of buying. They rent because they have to.

We can improve the bargaining power of renters either though changes to rental regulations, or through improving the home-buying outside option. This means that the very act of reducing prices, via LVR restrictions, removing the FHOG, and limiting CGT discounts and negative gearing, means that home buying will reduce in cost compared to renting, allowing buying to be a financially viable alternative to more currently renting households.

For more discussion on the issue I recommend this paper, which contains a wealth of data on rental housing in the OECD, and reasonable discussion about these important issues, including rent controls and the need to shift bargaining power towards tenants to reduce housing costs.

Once we focus on the rental price of housing, and not the price of the financial asset of residential property, we get a very different picture of the housing affordability debate. In fact, we get a picture where housing affordability has remained relatively stable in Australia over the past 20 years. And one where home ownership may even be a policy goal at odds with the goal of affordable rental housing.

But that doesn’t mean we can’t change the situation if we wanted to. We just have to accept that doing so involves a massive transfer of wealth.

Inequality is a capital vs labour story

I was in a seminar recently where the presenter explored some trends in income inequality in Australia, Canada and the US over the past century. While there was much to like about economists trying to unravel this issue, including the repeated reminders that representative agent models cannot deal with this problem, I had some niggling doubts that the whole story was being considered. I thought this presenter was sticking to only the issues deemed acceptable to discuss in the economics community, while ignoring the more important political issues.

First the good parts. Education is not a solution to income inequality. Canada and the US in particular are very highly educated countries, whose average educational attainments have soared for the past 30 years - the exact period that also saw huge growth in inequality. 

It was acknowledged that the greater the degree of inequality, the easier it is to buy favours within political processes, further entrenching the income divide. It was nice to see economists raise these political points, but equally it highlighted how much of a disgrace it is that economists (and economic theory) play such a key role in capturing political processes for the 1%. 

Now to the issue I believe is the crux of the income equality debate.

I was informed in the presentation that the inequality story of the past 20 years is not about the division of income between capital and labour. Labour incomes in the top 1% are increasing very rapidly too. Sure. But we know that CEO and executive pay is more closely linked to capital returns than ever before, following the wide acceptance of the principle of incentive pay and aligning executive pay to share market performance. 

When I look at the data from the Henry tax review, I find that in fact that the distribution of income from capital is far more distorted towards the upper end than income alone. 

I’ve borrowed the chart below from the Henry Review website. What we see is that the top 5% of income earners in Australia get half of total national income from owning capital assets. While they only get 15% of the wages. 

We can even see that the bottom 20% are making capital losses (capital gains and dividends), highlighting the process by which the poor are becoming more dependent on labour income. 

Many researchers do in fact note that decreasing labour share, and therefore increasing capital share, of national income has been a global trend since the 1970s. What few say however is that this is trend is a result of policy choices informed by neoliberal ideology. We certainly could have avoided this trend if we desired. It was simply a matter of different policy choices. And to reverse the trend is also very simple, should be desire to do so. 

There is no 'natural' outcome when it comes to inequality.

In a mere technical sense, reversing the trend couldn’t be easier. Off hand I can think of dozens of policies; from inheritance taxes, greater public transparency of personal income data (including trusts), land taxes, improving the power of shareholders in the determination of executive pay, grants of land or capital for public service, and more. The options are limitless. 

The barrier to change is modern realpolitik. Those at the top have captured the political process, partly by capturing the media. Any change will entail a massive redistribution of wealth from those who bankroll the political parties, to those with the least resources, the least education and the least interest. 

This is the heart of the matter, and one we repeatedly avoid discussing.

Pretending to care about housing affordability

Australia is embarking on another Inquiry into housing affordability. In the past decade almost every government body, at every level of government, that has any function related to any aspect of housing policy, has conducted similar inquiries. With zero results.

Is it time we stopped pretending to care?

I made a submission (pdf here) to the inquiry, not because I think things will change, but to highlight the 'big picture' considerations in any housing policy. You know, the ones we don't talk about because the Overton window has been slammed shut by decades of well-funded propaganda by wealthy interest groups. Just look at the content of other submissions to see how they miss the big picture, either simply promoting their own financial interests or preserving their reputation by reiterating arguments deemed acceptable in polite company.

My main point is this - any policy that successfully reduces housing rents, and subsequently home prices, entails a massive redistribution of wealth from the richest to the poorest. I wrote the following in my submission.

At current prices Australia’s total housing stock is valued at around $5 trillion. If a policy successfully reduced rents and prices by 20% it would wipe $1 trillion of value from this market. Purchasing power of around $40 billion per year would be redistributed from the almost 6 million current home owning households and 1.8 million residential property investors, to the 2.8 million renters, along with future home buyers and owners of other non-residential domestic assets. 

There is no win-win scenario. Housing affordability is almost completely a question about the distribution of wealth in society. 

To understand the magnitude of potential redistribution from successful policy to improve housing affordability, a reduction in housing rents by even as little as 10%, would lead to possibly the largest redistribution of wealth from the richest to the poorest in Australia's recent history.

Politically it makes sense to pander to the majority. And while the majority of households still own their own home, absolutely nothing will be done to reduce rents and home prices. Even the ridiculous fig leaf of the First Home Owners Grant is actually a subsidy to existing home owners. It's the most fantastical piece of doublespeak to not call it what it really is - the Current Home Owners Grant.

This is the elephant in the room on housing policy. Here. Right here. I'm pointing at it.

Watch me be ignored.

The 140 year cycle in macroeconomic thought

I am reading Progress and Poverty: An Inquiry into the Cause of Industrial Depressions and of Increase of Want with Increase of Wealth: The Remedy by Henry George (free ebook available here).

I’ve been fascinated so far that the economic debates that occurred during the long recession of the 1870s are almost identical to those still occurring during the great recession. I would have expected more progress in macroeconomic thought in 140 years.

Here’s George describing the utter disarray of the economic elite of that time in explaining how the depression had arisen, and where to look for a remedy.

This is shown by the widely-varying attempts to account for the prevailing depression. They exhibit not merely a divergence between vulgar notions and scientific theories, but also show that the concurrence which should exist between those who avow the same general theories breaks up upon practical questions into an anarchy of opinion.

Upon high economic authority we have been told that the prevailing depression is due to over-consumption; upon equally high authority that it is due to over-production; while the wastes of war, the extension of railroads, the attempts of workmen to keep up wages, the demonetisation of silver, the issues of paper money, the increase of labour-saving machinery, the opening of shorter avenues to trade, etc., etc., are separately pointed out as the cause by writers of reputation.

The modern equivalents are

1870s excuses		2000s excuses
over-consumption	→	excess household debt
over-production	→	excess housing construction
wastes of war	→	government waste or regulation
high wages	→	high wages
currency debasement	→	currency debasement
labour-saving machinery	→	robots

I found even more interesting the debates about the nature of capital and wealth that occurred at the time. George criticised the writers of common textbooks for not being specific in their definitions which caused much confusion when applying economic reasoning to the problems of the day. It seems an awful lot like the Cambridge Capital debates of the 1970s and reminded me of debates (or indeed lack of debate) around foreign investment that appear to have subsided in the past few decades. 

Here’s a snippet, which shows George would firmly be on the side of Cambridge, England, in the capital debates, and would be firmly of the position that foreign investment is merely a transfer and is not wealth-creating. 

As commonly used, the word " wealth " is applied to anything having an exchange value. But when used as a term of political economy it must be limited to a much more definite meaning, because many things are commonly spoken of as wealth which in taking account of collective or general wealth cannot be considered as wealth at all.
...
Increase in the amount of bonds, mortgages, notes, or bank bills cannot increase the wealth of the community, that includes as well those who promise to pay as those who are entitled to receive.

The enslavement of a part of their number could not increase the wealth of a people, for what the enslavers gained the enslaved would lose. Increase in land values does not represent increase in the common wealth, for what land owners gain by higher prices, the tenants or purchasers, who must pay them, will lose. 

And all this relative wealth, which, in common thought and speech, in legislation and law, is undistinguished from actual wealth, could, without the destruction or consumption of anything more than a few drops of ink and a piece of paper, be utterly annihilated. 

By enactment of the sovereign political power debts might be cancelled, slaves emancipated, and land resumed as the common property of the whole people, without the aggregate wealth being diminished by the value of a pinch of snuff, for what some would lose others would gain. 

There would be no more destruction of wealth than there was creation of wealth when Elizabeth Tudor enriched her favourite courtiers by the grant of monopolies, or when Boris Godoonof made Russian peasants merchantable property. 

All things which have an exchange value are, therefore, not wealth in the only sense in which the term can be used in political economy. 

Only such things can be wealth the production of which increases and the destruction of which decreases the aggregate of wealth. If we consider what these things are, and what their nature is, we shall have no difficulty in defining wealth.

What amused me is that George looked for answers in political economy

It must be within the province of political economy to give such an answer. For political economy is not a set of dogmas. It is the explanation of a certain set of facts. It is the science which, in the sequence of certain phenomena, seeks to trace mutual relations and to identify cause and effect, just as the physical sciences seek to do in other sets of phenomena.Maybe it’s time to follow his lead, again, and look outside of sterile economic theory to resolve problems of macroeconomic instability.
