from Lars Syll Twenty-seven years ago yours truly wrote an article on revealed preference theory that got published in History of Political Economy (no. 25, 1993). Paul Samuelson wrote a kind letter and informed me that he was the one who had recommended it for publication. But although he liked a lot in it, he also wrote a comment — published in the same volume of HOPE — saying: Between 1938 and 1947, and since then as Pålsson Syll points out, I have been scrupulously careful not to...

from Dean Baker Economists and economic reporters all know that tariffs can lead to corruption. The idea is that if a government-imposed tariff raises the price of a product by 10-25 percent above the free market price, companies have a large incentive to find ways to avoid the tariff. This can mean reclassifying imports to get around the tariff or trying to curry favor with politicians to get exemptions. The New York Times and ProPublica have run several excellent pieces providing...

I happened to mention on Twitter that I now use the word “reform” without scare quotes, even when I think the reform in question is a bad one. In fact, that’s my default assumption when I see the word, at least in the context of economic policy. That led me to think about how much fof the 1980s and 1990s microeconomic reform program still stands up. Here’s the result from Threadreader (via @ScooterBodgie) Having privatised telecomms and (most electricity), government is now...

from Lars Syll I don’t see that we are even entitled to assume that reality accords to some model that humans are able to envisage … To say that Pandora knows what decision model she is facing can therefore be taken as meaning no more than that she is committed to proceeding as though her model were true … The price of abandoning psychology for revealed-preference theory is therefore high. We have to give up any pretension to be offering a causal explanation of Pandora’s choice behavior...

from Andri Stahel and RWER issue 93 As will be argued, a great part – and increasingly so – of the capital gains result from an inflationary increase in the monetary value of given financial assets and not from productive employment of capital, generating both capital-income and new wealth on its wake. Thus, we overlook the effect of the different kinds of capital both in fostering or not overall economic activity and the effect of that which has been termed “financialisation” on the...

So, far I’ve argued that the inequality of incomes in our society is largely a matter of luck rather than inherent personal ability, and that it is only distantly related to the social value of the contributions people make through their work. These conclusions undercut the idea that taxing those on high incomes will harm society by reducing incentives to work for the most able and social valuable workers. Although the evidence was already strong, the pandemic has brought these points...

Happy Every Economic Statistic in the World Day! 4. Manufacturing continued to expand strongly in September This morning’s final economic report is the ISM manufacturing index for September. This is a short leading indicator, and the new orders subindex specifically is one of the 10 components of the Index of Leading Indicators. A neutral reading is 50. The overall index came in at 55.4, and the new orders subindex came in at 60.2: So while the...

from Lars Syll Why, it might be objected, should the goal of social science be mere causal explanations of particular events? Isn’t such an attitude more the province of the historian? Social science should instead be concentrating on systematic knowledge. The Prisoner’s Dilemma, this objection concludes, is a laudable example of exactly that – a piece of theory that sheds light over many different cases. In reply, we certainly agree that regularities or models that...
