I used to live in Boston and visited recently for the first time in a while. The red line was so slow between Central Square and Harvard that I thought there must have been some kind of mechanical failure, but when I mentioned it to friends

(Ignore my previous reply I found it myself). To be fair to the authors, it is not their primary specification, that was a linear probability model. The logit model is just a robustness check to make sure the linearity assumption isn't

Citing a paper needn't be a celebration of it, you can cite a paper to say "these guys find X but..."

Sorry to be pedantic, but although Monte Carlo simulations are based on pseudo-randomness, I still think it is good practice that they have deterministic results (i.e., use a given seed) so that the exact results can be replicated. If the p

If you haven't seen it already, the Farm Hall transcripts provide a fascinating insight into the failure of the Nazi nuclear effort: https://www.nybooks.com/articles/1992/08/13/the-farm-hall-tr...

FYI, the word is 'tenet', a tenant is a person who lives in a particular residence.

I sympathize with the author's disdain for brutalist and some deconstructivist work. But to suggest that all contemporary architecture is a movement towards creating deliberately alienating and impractical buildings, seems to me very w

Quasi-experimental variation refers to situations in which assignment of treatments is 'as good as random' but treatments weren't assigned by the researchers in an RCT. A classic example is Angrist and Lavy https:/&#x2F

Well, at the very least, the argument over hypothesis formation is not specific to economics. The philosopher of science Karl Popper argued that science should aim to empirically falsify hypotheses, and that the way scientists develop those

I admit I haven't read or even heard of Kate Raeworth, but I am an academic economist. Most modern economic research is empirical, a paper poses a policy-relevant empirical question 'did policy X reduce unemployment' and then

Look at the latest edition of QJE. You will see mostly studies addressing a particular policy question, e.g., 'what was the effect of this policy change on unemployment' which they answer using randomly controlled trials or quasi-

My understanding is that medieval Rabbis (notably the Maimonides) explicitly discuss cannabis consumption and its psychological effects. The plant also gets some discussion in the Talmud but in the context of its use in fabric and as candle

I think this misses a possibly very important effect: agglomeration. Programmers in the Bay Area were not all born there, many (most?) chose to move there, some from elsewhere in the US, some from abroad. If those programmers who are more s

I like Schiele's work becuase I find his grimy, corpse-like figures to be very aesthetically pleasing. I do not find it 'beautiful' in the sense that an old Venetian painting of a cherub is beautiful, I simply find the delibe

If you have a finite set of symbols, then the set of finite sequences of those symbols is countable. The key here is 'finite sequences', if you were to allow for infinite sequences then the set if uncountable.

Cities skew democrat, particularly inner-cities. Those built-up areas are also more vulnerable to the spread of disease.

Among the first things you learn in microeconomic theory are the expected utility axioms (developed by Von Neumann and Morganstern), and Afriat's theorem. These results give conditions under which an agent's behavior is indistigui

I don't see how micro-founded macro models equate utility with willingness to pay? Work-horse New Keynesian models begin with a representative agent so willingness to pay of different consumers doesn't even make sense in this cont

As someone has already commented, the definition of an 'efficient market' in no way equates willingness to pay with utility, and in fact economists seldom make this assumption. Pareto efficiency is very deliberately not utilitaria

My problem with the 'Bayes=rationality' type of argument is that it ignores context and isn't really a case for reporting Bayesian vs frequentist estimates. If I am a researcher publishing results then I have an audience who

Both of your assertions are inaccurate. First of all the economics prize, while not an original prize, is recognized by the Nobel foundation, and that 'Swedish bank' is the central bank of Sweden. Secondly, the idea that modern ac

In the context of the incompleteness theorem a 'theory' consists of a formal language to describe theorems, some primitive axioms and some rules that can be used to prove theorems from the axioms. Godel's incompleteness theor

Suppose we are able to formulate a very neat, parsimonious mathematical model and it happens to extremely accurately describe every physical phenomenon, so accurately that we cannot find even the tiniest violation. Now, that does not mean t

>Why is the implication that this is due primarily to sexism? Well perhaps because of the persuasive evidence the article cites from peer-reviewed journals. For example, in the paragraph below from the article: "In one experiment, r
