Should wasteful competition for positional goods be taken into account in tax policy?


In my last post I began my review of Robert Frank’s ‘The Darwin Economy’, by outlining how Adam Smith viewed the strivings of people to better their condition as being motivated to a large extent by concerns about their relative position in society. I suggested that if there are negative externalities associated with strivings to improve relative position, these should be balanced against the positive externalities relating to technological progress identified by Smith.

The negative externalities that Robert Frank is most concerned about arise when people forgo something that they value (e.g. leisure or workplace safety) in order to engage in competition for positional goods. The basic idea is that while this competition makes sense from the perspective of each individual, it is socially wasteful because individuals are forgoing something they value in order to compete for positional goods.

There is an important definitional issue, which I will come to later, about whether the supply of positional goods is fixed. Let us assume initially, however, that there is only one positional good which is fixed in supply – housing land with views – and that humans have such a strong urge to obtain a house with a good view that, once their subsistence needs have been satisfied, all their efforts go into obtaining better views. If we now make the additional assumption that the government has to raise a certain amount of revenue to fund provision of public goods (e.g. defence, law enforcement) I think it would probably be reasonable to suppose that a tax on income above a certain level, which causes people to substitute leisure for income, would be an efficient tax to use in such circumstances. (This runs counter to my prior view which would have been in favour of a tax, or combination of taxes, with a neutral impact on income-leisure choices.)

Now, let us add some complications relating to the real world. Account should be taken of the fact that different people have different preferences and tastes. Some people are particularly interested in houses with views, some like to live near water, some are interested in living near good educational facilities and some like to live near their work. Then, there are the people who prefer to spend additional income on goods other than housing.

House sites in good locations are not the only good for which there is a relatively high income elasticity of demand. In the case of most high income elasticity goods, however, an increase in demand tends to result in a supply response and a reduction in price. Moreover, many studies suggest that there is a relatively high income elasticity of demand for leisure. Such considerations suggest to me that potential economic losses associated with competition for positional goods are likely to be quite small.

At this point I should introduce the further complication relating to the definition of positional goods. Frank adopts Fred Hirsch’s definition of positional goods ‘as ones whose evaluations are particularly sensitive to context’. House sites with views would be considered to be strongly sensitive to context if people would generally prefer to live in a location where they have better views than their neighbours, than to live in a location where the views are generally much better, but their neighbours have better views than they have.

On the basis of thought experiments he has asked students to undertake, Frank suggests that size of house is strongly sensitive to context, whereas workplace safety and time spent on vacation are not strongly sensitive to context. Frank argues that positional concerns are stronger for luxury goods than for necessities. He suggests that since ‘luxury is an inherently context-dependent phenomenon, it’s uncontroversial to say that the last dollars spent by those who spend most are most likely to be spent on luxuries’. This reasoning leads him to argue in favour of a steeply progressive consumption tax to replace personal income tax.

In the end, it seems to me that the view Frank is presenting boils down to an assertion that those fortunate (or silly) enough to have high levels of consumption spending impose an externality on the rest of the community who feel that their relative standing is diminished unless they make the sacrifices required to emulate this behaviour. The main problem I have with this this line of reasoning is that people can choose not to get involved in such emulation games, and many people have made such choices.

Furthermore, I don’t think relative income or consumption levels are nearly as important to life satisfaction as people might suggest in their responses to thought experiments. A rough calculation I reported on this blog a few years ago suggests that the probability of a poor person in a rich country being satisfied with life is about 60 percent higher than for a rich person in a poor country.

International migration patterns are also inconsistent with the view that relative position is of huge importance. Many people seem to be willing to migrate from poor countries, where they are relatively wealthy, to wealthy countries, where they are relatively poor, in order to give better opportunities to their children.

My bottom line is that while I think there may be a grain of truth in the idea that competition for some positional goods (goods which are fixed in supply) is wasteful, Robert Frank has not succeeded in establishing a case on efficiency grounds for a steeply progressive consumption tax.

What did Adam Smith think of externalities associated with the efforts of individuals to improve their relative position?


bookjacketI have enjoyed reading Robert Frank’s new book, ‘The Darwin Economy: Liberty, Competition and the Common Good’, more than I thought I would. This may be because I felt that the book had been written for people like me - the author seems to want people who have a strong regard for individual liberty to give serious consideration to his views.

I had expected Frank to argue that competition for positional goods involves a negative externality because those who are most successful are envied by many of those who are less successful. However, the view he presents of the nature of externalities associated with competition for positional goods is more subtle and less easily dismissed.

The starting point of Frank’s analysis is the ‘invisible hand’ of the market, which Adam Smith had suggested in ‘Wealth of Nations’ leads self-interested individuals to promote the greater good of society, without intending to do so. Frank describes Smith’s invisible hand as ‘a genuinely groundbreaking insight’, even though, as Smith recognized, the invisible hand ‘breaks down’ to some extent in the presence of externalities, public goods, and so forth. The particular negative externality that Frank is most concerned about in this book is associated with circumstances where individual rewards depend on relative performance and result from the strivings of individuals to improve their relative position. He contrasts this striving to improve relative position (which he describes as Darwinian competition) with the benign competitive forces associated with Adam Smith’s invisible hand.

Frank’s discussion of the different views of competition that he attributes to Darwin and Smith reminded me that Adam Smith had actually written about the strivings of individuals to improve their relative positions in ‘The Theory of Moral Sentiments’ (TMS). Smith suggested in TMS that what people hope to achieve by bettering their condition is not ‘ease’ or ‘pleasure’ but ‘to be taken notice of with sympathy, complacency and approbation’ (p 50-51, Liberty Fund edition, 1982). Later in the book, Smith suggests, however, that ‘the poor man’s son, whom heaven in its anger has visited with ambition’ imagines that if he attained wealth and greatness ‘he would sit still contentedly, and be quiet, enjoying himself in the thought of the happiness and tranquillity of his situation’. According to the story, this ambitious man endures a great deal of misery striving to better his position. By the time he achieves his goal, however, he is near the end of his life ‘his body wasted with toil and diseases, his mind galled and ruffled by the memory of a thousand injuries and disappointments …’. At this point he begins to think that ‘wealth and greatness are mere trinkets of frivolous utility’ offering little ‘ease of body or tranquillity of mind’ (p 181).

In my view, Smith’s story understates the benefits that people obtain from wealth because it doesn’t take account of the greater autonomy wealth enables them to enjoy. (I have discussed the link between wealth and autonomy previously on this blog.)

Smith was suggesting that people tend to make cognitive errors of the kind discussed by Daniel Gilbert in his book, ‘Stumbling on Happiness’. This view of strivings to improve relative position differs from that of Robert Frank, who does not rely on departures from the individual rationality assumptions normally used in neo-classical economics.

The similarity between the views of Adam Smith and Robert Frank in relation to strivings to improve relative position lies in the fact that both seem to see this as more or less a zero sum game, with externalities involved. Adam Smith wrote as follows about the externalities associated with the strivings of individuals to better their condition:
‘The pleasures of wealth and greatness … strike the imagination as something grand and beautiful and noble, of which the attainment is well worth all the toil and anxiety which we are apt to bestow upon it.
And it is well that nature imposes upon us in this manner. It is this deception which arouses and keeps in continual motion the industry of mankind. It is this which first prompted them to cultivate the ground, to build houses, to found cities and commonwealths, and to invent and improve all the sciences and the arts, which ennoble and embellish human life; which have entirely changed the whole face of the globe, have turned the rude forests of nature into agreeable and fertile plains, and made the trackless and barren ocean a new fund of subsistence, and the great high road of communication to the different nations of the earth’ (p 183).

These days many people would be less inclined to count as a benefit some of the ways in which the face of the globe is being changed by the motion of industry. But Smith’s insight that strivings of individuals to improve relative position can encourage technological progress is still relevant. If such strivings also result in negative externalities, those need to be balanced against the positive externalities that Adam Smith identified.
I promise to write about Robert Frank’s views in my next post.

Can measurement of subjective well-being help us to assess whether life is getting better?


The British government has recently taken some steps toward measurement of subjective well-being in the hope that this will provide ‘a general picture of whether life is improving’ and eventually ‘lead to government policy that is more focused not just on the bottom line, but on all those things that make life worthwhile’.

The quoted words are from David Cameron, the British prime minister. I find it interesting that he refers to ‘the bottom line’ as though the bottom line in British politics has always had a pound sign in front of it. Philip Booth, editor of the recent Institute of Economic Affairs (IEA) publication ‘… and the Pursuit of Happiness’, suggests that the prime minister was attacking a ‘straw man’; the British government has always had a multitude of objectives.

Booth makes the point that attempts to ‘centrally direct policy toward improving general wellbeing’ will fail just as attempts to increase GDP growth through use of central planning also failed. I agree with the point, but I suspect that it is also a straw man. I doubt whether David Cameron is proposing to adopt some form of central planning in an attempt to raise national happiness. It seems to me that attempts to obtain a better picture of whether life is improving are no more likely to encourage central planning than was the measurement of national income likely to encourage central planning. Like many happiness researchers, the pioneers in the field of national income measurement were of an interventionist frame of mind. They actually wanted better measures of economic activity as an aid to implementation of Keynesian macro policies.  The central planners were not slow to jump on the national income measurement bandwagon, but there was no slippery slope leading inevitably from national income measurement to increased government intervention.

However, I can’t claim to know what the British prime minister has in mind. Initial survey work by the Office of National Statistics (ONS) has focused on a comparison of different measures of subjective well-being. Some of the results are interesting. For example, there is a fairly high level of correlation (0.66) between responses to a standard life satisfaction question (How satisfied are you with your life nowadays?) and a eudenomic question (Overall, to what extent do you think the things you do in your life are worthwhile?).

Yet, that kind of information will not tell us much about whether life is getting better. As Paul Ormerod demonstrates in his chapter of the IEA publication, levels of life satisfaction in high income countries tend to fluctuate over time without any obvious trend – and despite improvements in many different well-being indicators. I think the metaphor of a ladder attached to a helicopter, which I used in a recent post, is helpful to an understanding of why successive snapshots of life satisfaction cannot measure progress. If I am climbing a ladder that is attached to a helicopter, my height above the ground depends on the height of the helicopter as well as on which rung of the ladder I have reached. The ladder represents the benchmark of possibilities against which I assess my life satisfaction, but upward movement of the helicopter (i.e. expanding possibilities) may be my main source of progress.

In my view, if you want to know whether people feel that their lives are improving you need to provide them with an appropriate benchmark against which to make that comparison. The ONS survey enables this by also asking respondents to rate their life satisfaction a year ago and five years ago. The scores for life satisfaction five years ago and one year ago were slightly lower than those for current life satisfaction. This suggests, somewhat surprisingly, that Brits generally feel that their lives are still improving despite the global financial crisis and its aftermath. That kind of information seems to me to be worth having.

Unfortunately, I couldn’t find any discussion in the IEA publication of what measures of progress would be superior to the successive snapshots of life satisfaction that are targeted for criticism by several of the authors. The publication certainly serves a useful purpose in bringing together the contributions of a range of authors who question false assertions that have been made on the basis of happiness research and caution against government attempts to use the findings of happiness research to introduce policies to promote happiness. Nevertheless, I was slightly disappointed that the editor did not show a little more sympathy for the idea that there could be some merit in the aim of the British prime minister to obtain a better picture of whether life is improving in that country. 

I expect that if government policies were focused more clearly at expanding the opportunities that make life worthwhile, there would actually be less government regulation in most countries, including the UK.

Does GNH measure progress towards a better society?


In my last post, ‘Can happiness be aggregated?’, I suggested that any statement about aggregate happiness or gross national happiness (GNH) involves judgements – explicit or implicit – about the characteristics of a good society.

I used the example of Mary, who is flourishing at level 9, and Jane, who is just surviving at level 1, and asked whether their combined level of flourishing is equivalent to that of two other people who are flourishing at level 5 ( i.e. (9+1)/2).  I suggested that you may feel that combining the ratings of different individuals together should involve value judgements rather than just arithmetic. I argued that if we introduce value weights into the process of aggregating the flourishing of different individuals, we are making a judgement about the extent to which the distribution of flourishing is consistent with our views about characteristics of a good society. 

I think the issues raised by the example of Mary and Jane can be brought into sharper focus if we consider whether aggregate flourishing increases to the same extent if Mary’s level of flourishing rises from 9 to 10 as when Jane’s level of flourishing rises from 1 to 2. I think most people would feel that Jane’s increased flourishing should receive more weight than Mary’s in the assessment of aggregate happiness. As argued above, the assignment of relative weights involves a value judgement. Different people can be expected to have different opinions about this matter.

The people responsible for the GNH survey in Bhutan have taken the position that ‘beyond a certain point, we don’t need to keep adding in higher achievements to the quality of life mechanically’. Their methodology would not count the increase in Mary’s level of flourishing as making any contribution to GNH on the grounds that it is appropriate to confine attention to ‘a middle band of achievements that contribute significantly to human wellbeing for most people’. I am not sure whether these implicit weightings reflect a consensus of the people of Bhutan, but in any case the weightings in the GNH index have validity as an expression of the values of the elected government.

The way I see it, Bhutan’s GNH index is the method that the government of Bhutan has chosen to measure progress toward a better society.
