In his history of experimental social science — Randomistas: How radical researchers are changing our world — Andrew Leigh gives an introduction to the RCT (randomized controlled trial) method for conducting experiments in medicine, psychology, development economics, and policy evaluation. Although it mentions there are critiques that can be waged against it, the author does […]

Causal effects are comparisons of what did happen with what would have happened if people had received different treatments. Randomized treatment assignment has reduced this problem to the minor technical problem of drawing an inference about a finite population of people on the basis of a probability sample from that population. Expressed differently, if we […]

Purchasing power parity doctrine is examined by sophisticated statistical and econometric techniques. The time series of aggregated price levels and the nominal exchange rates are treated as a random sample. Most papers of this type deal with the technical properties of the slightly different data sets. To take some examples (at random): “Two potential problems […]
Yours truly’s latest book has made it onto Amazon’s lists of best sellers in economics and econometrics. I am — of course — truly awed, honoured and delighted.
To understand the relationship between economic data and economic phenomena, it is helpful first to be clear about what we mean by each of these terms. Following Jim Woodward (1989), we can characterize “phenomena” as features of our experience that we take to be “relatively stable” and “which are potential objects of explanation and prediction […]
Suppose there is a series of Bernoulli trials, that each trial has the same probability p of success, and that the trials are independent—like the standard model of coin tossing, treating ‘heads’ as ‘success.’ Then the Law of Large Numbers guarantees that the rate of successes converges (in probability) to the probability of success. If […]
