摘要:This paper presents new evidence that increases in college enrollment lead to a decline in the average quality of college graduates between 1960 and 2000, resulting in a decrease of 6 percentage points in the college premium. A standard demand and supply framework can qualitatively account for the trend in the college and age premia over this period, but substantial quantitative adjustments are needed to account for changes in quality.

摘要:We often deal with uncertain events for which no probabilities are known. Several normative models have been proposed. Descriptive studies have usually been qualitative, or they estimated ambiguity aversion through one single number. This paper introduces the source method, a tractable method for quantitatively analyzing uncertainty empirically. The theoretical key is the distinction between different sources of uncertainty, within which subjective (choice-based) probabilities can still be def...

摘要:We show that current differences in trust levels within Africa can be traced back to the transatlantic and Indian Ocean slave trades. Combining contemporary individual-level survey data with historical data on slave shipments by ethnic group, we find that individuals whose ancestors were heavily raided during the slave trade are less trusting today. Evidence from a variety of identification strategies suggests that the relationship is causal. Examining causal mechanisms, we show that most of t...

摘要:We examine Popper's falsifiability within an economic model in which a tester hires a potential expert to produce a theory. Payments are contingent on the performance of the theory vis-a-vis data. We show that if experts are strategic, falsifiability has no power to distinguish scientific theories from worthless theories. The failure of falsification in screening informed and uninformed experts motivates questions on the broader concepts of refutation and verification. We demonstrate an asymme...
