One of the bests books I’ve read this year was Serge Audier’s & Jurgen Reinhoudt’s relatively unknown (unfortunately!) translation of the protocols of the Walter-Lippmann-Colloquium. The NOUS-Network organized a wonderful seminar in which we thoroughly discussed the book and the emergence of Neoliberalism. For the preparation of this weekend’s Hayek-Kreis seminar, I reread the book and stood once again in awe of the magnificence of the discussion during the Colloquium.
By the way: If you are an undergraduate, graduate, or PhD scholar, please consider joining the NOUS-Network for Constitutional Economics and Social Philosophy as a Young Affiliate! NOUS is an information platform and a community for interdisciplinary research. The network links all academic fields relevant for thinking about social order and liberty. It spans philosophy, politics, economics and fosters scholarly research, contact and exchange.
In the following excerpt, it becomes clear, that the participant’s opinion on the psychological and sociological causes of the decline of Liberalism differed significantly. Mr Rüstow eloquently captures the standpoints of the two opposing groups (not without bias to be fair) and even cheekily disses Ludwig von Mises.
“Mr Rüstow: ‘All things considered, it is undeniable that here, in our circle, two different points of view are represented. One group does not find anything essential to criticize or to change in traditional liberalism, such as it was and such as it is, apart from, naturally, the adjustments and the current developments that are self-evident.
In their view, the responsibility for all the misfortune falls exclusively on the opposite side, on those who, out of stupidity or out of malice, or through a mixture of both, cannot or do not want to discern and observe the salutary truths of liberalism.
We, on the other hand, we seek the responsibility for the decline of liberalism in liberalism itself; and, therefore, we seek the solution in a fundamental renewal of liberalism. In order to justify in a positive manner this second point of view, I have to refer to what I have said and, especially, to the excellent arguments of Mr Lippmann.
Here, I would only like to draw attention to the fact that if the unwavering representatives of old liberalism were right, the practical prospects [for liberalism] would be almost hopeless. Because it does not really seem that old liberalism has gained in persuasive and in seductive force or that the arguments, no matter how shrewd they may be, of these representatives have the least possibility of bringing about a conversion movement within the realm of Bolshevism, Fascism, or of National Socialism. If they did not listen to Moses and the prophets—Adam Smith and Ricardo—how will they believe Mr. von Mises?'”

Bryan Caplan is an optimist. He thinks that economists do many errors in estimating GDP (overall well-being). He is right in the sense that we are missing many dimensions of welfare improvements in the last half-century (see here, here and here). These errors in measurements lead us to hold incorrectly pessimistic views (such as those of Robert Gordon). However, Prof. Caplan seems to argue (I may be wrong) that all measurements problems and errors are greater than zero. In other words, they all cut in favor of omitting things. There are no reasons to believe this. Many measurement problems with GDP data cut the other way – in favor of adding too much (so that the true figures are lower than the reported ones).
Here are two errors of importance (which are in no way exhaustive): household output and adjustments for household size.
From the 1910s to the 1940s, married women began to enter moderately the workforce. This trickle became a deluge thereafter. National GDP statistics are really good at capturing the extra output they were hired to produce. However, national GDP statistics cannot net out the production that was foregone: household output.
A married woman in 1940 did produce something: child-rearing, house chores, cooking, allowing the husband to specialize in his work. That output had a value. Once offered the chance to work, married women thought the utility generated from producing “home outputs” was inferior to the utility generated from “market work”. However, the output that is measured is only related to market work. Women entered the labor force and everything they produced was considered a net addition to GDP. In reality, any economist worth his salt is aware that the true improvement in well-being is equal to the increased market output minus the forsaken house output. Thus, in a transition from a “male-labor force” to a “mixed labor force”, you are bound to overestimate output increases.
How big of an issue is this? Well, consider this paper from 1996 in Feminist Economics. In that paper, Barnet Wagman and Nancy Folbre calculate output in both the “household” and “market” sectors. They find that even very small changes in the relative size of these sectors alter growth rates by substantial margins. Another example, which I discussed in this blog post based on articles in the Review of Income and Wealth, is that when you make the adjustment over four decades of available Canadian data, you can find that one quarter of the increase in living standards is eliminated by the proper netting out of the value of non-market output. These are sizable measurement errors that cut in the opposite direction as the one hypothesized by prof. Caplan (and in favor of people like prof. Gordon).
Changes in household sizes also create overestimation problems. Larger households have more economies of scale to exploit than smaller households so that an income of $10,000 per capita in a household of six members is superior in purchasing power than an income of $10,000 per capita in a single-person household. If, over time, you move from large households to small households, you will overestimate economic growth. In an article in the Scottish Journal of Political Economy, I showed that making adjustments for household sizes over time yields important changes in growth rates between 1890 and 2000. Notice, in the table below, that GDP per adult equivalent (i.e. GDP per capita adjusted for household size) is massively different than GDP per capita. Indeed, the adjusted growth rates are reduced by close to two-fifths of their original values over the 1945-2000 period and by a third over the 1890 to 2000 period. This is a massive overestimation of actual improvements in well-being.
A large overestimation
If you assemble these two factors together, I hazard a guess that growth rates would be roughly halved (there is some overlap between the two so that we cannot simply sum them up as errors to correct for – hence my “guess”). This is not negligible. True, there are things that we are not counting as Prof. Caplan notes. We ought to find a way to account for them. However, if they simply wash out the overestimation, the sum of errors may equal zero. If so, those who are pessimistic about the future (and recent past) of economic growth have a pretty sound case. Thus, I find myself unable to share Prof. Caplan’s optimism.
I came across a simple but important question on Quora: Is it wrong to aspire to be a minimalist? Doesn’t this negatively affect the country’s GDP?
I see two big lessons here: 1) wise use of metrics requires wisdom… i.e. appropriate interpretation and critical thinking. 2) Maximization is just one version of one part of the whole story. (There are also important questions to ask about what we can expect from others, but I’ll leave that for the comments.)
Readers of NOL should be familiar with the notion that GDP is only an imperfect proxy for well being. But not everyone is so we have to repeat ourselves. There’s what we’re after, and there’s what we can measure, and the two are not the same. GDP is a really clever way to aggregate total production in an economy, but production is only valuable to the extent we’re producing the things that actually improve people’s lives. It’s easy for busy people to confuse a proxy measure for the latent variable we actually care about, so we need someone whispering in the emperor’s ear “the metric is not the mission.”
Economics is easier to describe using the simplifying assumption that people want more stuff. It’s easy to forget that people also want more leisure (and so less work). This is a subtle reappearance of the seen and unseen. We can see when someone gets a cool new car and we can’t see when someone has a fun evening with friends and family. We have to check our bias towards trying to get more stuff and remember that reducing work is another feature of human flourishing.
