Real-World Economics Review

from Asad Zaman Note that this is a very POSITIVIST idea — if the surface appearances match, that is all that matters.         I quote a passage from Pearl: The Book of Why, which provides a gentle introduction to the newly developed field (largely by him) of causal inference via path diagrams: In 1950, Alan Turing asked what it would mean for a computer to think like a human. He suggested a practical test, which he called “the imitation game,” but every AI researcher since then has...

from Dean Baker It is often said that intellectuals have a hard time dealing with new ideas. This is perhaps nowhere better demonstrated with the fixation with patent monopolies as the primary mechanism for financing the development of new drugs. Bloomberg gave us a beautiful example of this narrow mindedness with a column from Max Nisen on the possibility that China may require the compulsory licensing of a patent on a drug developed by Gilead, in order to produce a treatment for the...

from Lars Syll In econometrics one often gets the feeling that many of its practitioners think of it as a kind of automatic inferential machine: input data and out comes casual knowledge. This is like pulling a rabbit from a hat. Great — but first you have to put the rabbit in the hat. And this is where assumptions come into the picture. As social scientists — and economists — we have to confront the all-important question of how to handle uncertainty and randomness. Should we equate...

from Asad Zaman This is the continuation of a sequence of posts on methodology of economics and econometrics (For previous posts, see: Mistaken Methodologies of Science 1, Models and Realities 2, Thinking about Thinking 3, Errors of Empiricism 4, Three Types of Models 5, Unrealistic Mental Models 6, The WHY of Crazy Models 7, The Knowledge of Childless Philosophers 8, Beyond Kant 9,). In this (10th) post, we consider the methodology of econometrics, which is based on Baconian or...

from Dean Baker Last week, Antonio Weiss, along with co-author Laura Kawano, released a paper advocating a financial transactions tax (FTT). I have long been an advocate of FTTs, so I’m always glad to see another paper making the case. However, what made this paper especially noteworthy is Weiss’s background. Weiss had been a top Treasury official under President Obama, and previously a partner at the investment bank, Lazard, so he is not the sort of person who would typically be expected...

from Blair Fix You can’t get the right answer when you ask the wrong question. This truism, I’ve come to believe, explains much of what is wrong with economics. When it comes to studying income, economists ask the wrong question. Economists, I argue, have mostly asked: is income fair? The problem is that this is a moral question, not a scientific one. It has no scientific answer. When the wrong questions get entrenched You can’t get the right answer when you ask the wrong question. This...

fro Norbert Häring If the trend of the last two decades continues, index funds could control 40 percent of the voting rights in the largest corporations by 2040.The share is already up to 25 percent in the US. There a two perspectives on this. Some scholars say it threatens shareholder value, others fear it will lead to too much of it. I side with the latter. … Law-and-economics professors Lucian Bebchuk and Scott Hirst from the Universities of Harvard and Boston make the extrapolation of...

from Lars Syll The gender pay gap is a fact that, sad to say, to a non-negligible extent is the result of discrimination. And even though many women are not deliberately discriminated against, but rather self-select into lower-wage jobs, this in no way magically explains away the discrimination gap. As decades of socialization research has shown, women may be ‘structural’ victims of impersonal social mechanisms that in different ways aggrieve them. Wage discrimination is unacceptable....
