Li e não gostei

Li um livro de Amartya Sen (Sobre ética e economia, fininho e custou 45 pratas!!!) e não gostei. Muitas das afirmações no livro eram sem base nenhuma que não a ideológica (não me incomoda um livro que queira expor uma ideologia mas sim um que queria lhe dar ares científicos). Pareciam versões daquela piada do português e do aquário.

Depois dessa risquei o ganhador do Nobel da minha lista. Economia para mim é um hobby e não posso me dar o luxo de gastar dinheiro no que eu considero porcaria.

Gene Epstein também não gosta dele:

At the beginning of his 1981 journal article, "Ingredients of Famine Analysis" (one hopes he used that title ironically), we confront a graph with lots of lines and curves on it, in which the horizontal axis is labeled "Food" and the vertical axis "NonFood" and underneath it we read, "With a price ratio p, and a minimum food requirement OA, the starvation set Si is given by the region OAB. If the endowment vector is xi, the person is in a position to avoid starvation... ." and on and on in that vein.

All this is in the service of drawing that simple distinction between access and availability before he goes on to the actual evidence.

And even regarding his actual analysis of famines, it's hard to completely trust his judgment. By solely grinding the socialist axe of access to supply over supply availability, he gives the latter issue a short shrift that is inappropriate.

For instance, he writes sweepingly that the food security of people in the Western capitalist economies "is not the result of any guarantee that the market or profit-maximization has provided, but rather due to the social security the state has offered."

Really? Could food security have nothing to do with the enormous gains in productivity that the market has brought to the farm? Even Sen himself writes of "deaths on a very large scale" because of famine conditions in China during 1959-61. The way agriculture was then organized probably had something to do with that awful tragedy, just as Soviet collectivism has a lot do with the dreadful prospect of food insecurity currently faced by the Russian people.

But getting back to how he combines those "tools from economics and philosophy," in the 1997 expanded edition of his book, On Economic Inequality, Sen writes, "Even for limited application of the merit principle-giving more than the 'norm' to the specially meritorious but not less than the 'norm' to the demented -- it can be argued that the measure of merit is culture-specific."

He then goes on to dismiss the merit principle thus: "While many of us may be content to live in a society which values the ability to lecture more than it values, say, the ability to make loud, shrill noises by blowing sharply through one's nose, we might be perfectly able to give long lectures about possible societies in which the latter quality would be the more desired virtue."
