I am a big fan of exploring economic ideas into greater depth rather than remaining on the surface of knowledge that I accumulated through my studies. As such, I am always happy when I see people trying to promote “alternatives” within the field of economics (e.g. neuroeconomics, behavioral economics, economic history, evolutionary economics, feminist economics etc.). I do not always agree, but it is enjoyable to think about some of the core tenets of the field through the work of places like the Institute for New Economic Thinking. However, things like Evonomics do not qualify for this.
And this is in spite of the fact that the core motivation of the webzine is correct: there are problems with the way we do economics today (on average). However, discomfort towards the existing state of affairs is no excuse for shoddy work and holding up strawmen that can be burned at the stake followed by a vindictive celebratory dance. The most common feature of those who write for Evonomics is to hold such a strawman with regards to rationality. It presents a caricature where humans calculate everything with precision and argue that if, post-facto, all turns out well then it was a rational process. No one, I mean no one, believes that. The most succinct summary of rationality according to economists is presented by Vernon Smith in his Rationality in Economics: Constructivist and Ecological Forms.
Such practices have led me to discount much of what is said on Evonomics and it is close to the threshold where the time costs of sorting the wheat from the chaff outweighs the intellectual benefits.
This recent article on “Dierdre” McCloskey may have pushed it over that threshold. I say “Dierdre” because the author of the article could not even be bothered to write correctly the name of the person he is criticizing. Indeed, it is “Deirdre” McCloskey and not “Dierdre”. While, ethymologically, Dierdre is a variant of Deirdre from the Celtic legend that shares similarities to Tristan and Isolde, the latter form is more frequent. More importantly, Dierdre is name more familiar to players of Guild Wars.
A minor irritant which, unfortunately, compounds my poor view of the webzine. But then, the author of the article in question goes into full strawman mode. He singles out a passage from McCloskey regarding the effects of redistributing income from the top to the bottom. In that passage, McCloskey merely points out that the effects of equalizing incomes would be minimal. The author’s reply? Focus on wealth and accuse McCloskey of shoddy mathematics.
Now, this is just poor understanding of basic economic concepts and it matters to the author’s whole point. Income is a flux variable and wealth is a stock variable. The two things are thus dramatically different. True, the flux can help build up the stock, but the people with the top incomes (flux) are not necessarily those with the top wealths (stock). For example, most students have negative net worth (negative stock) when they graduate. However, thanks to their human capital (Bryan Caplan would say signal here), they have higher earnings. Thus, they’re closer to the top of the income distribution and closer to the very bottom of the wealth distribution. My grandpa is the actual reverse. Before he passed away, my grandpa was probably at the top of the wealth distribution, but since he passed most of his time doing no paid work whatsoever, he was at the bottom of the income distribution.
Nevermind that the author of the Evonomics article misses the basic point of McCloskey (which is that we should care more about the actual welfare of people rather than the egalitarian distribution), this basic flaw in understanding why the difference between a stock and flux leads him astray.
To be fair, I can see why some people disagree with McCloskey. However, if you can’t pass the basic ideological Turing test, you should not write in rebuttal.
