Exposure to prenatal androgens affects both future behavior and life choices. However, there is still relatively limited evidence on its effects on academic performance. Moreover, the predicted effect of exposure to prenatal testosterone (T)–which is inversely correlated with the relative length of the second to fourth finger lengths (2D:4D)–would seem to have ambiguous effects on academic achievement since traits like aggressiveness or risk-taking are not uniformly positive for success in school. We provide the first evidence of a non-linear, quadratic, relationship between 2D:4D and academic achievement using samples from Moscow and Manila. We also find that there is a gender differentiated link between various measures of academic achievement and measured digit ratios. These effects are different depending on the field of study, choice of achievement measure, and use of the right hand or left digit ratios. The results seem to be asymmetric between Moscow and Manila where the right (left) hand generates inverted-U (U-shaped) curves in Moscow while the pattern for hands reverses in Manila. Drawing from unusually large and detailed samples of university students in two countries not studied in the digit literature, our work is the first to have a large cross country comparison that includes two groups with very different ethnic compositions.

We show how cheating in illegal gambling can be sustained in equilibrium, even when gamblers are aware of it. Not only is cheating pro…t-maximizing for operators, but it can also be utility-maximizing if it provides gamblers the opportunity to engage in other related activities that generate non-monetary rewards, such as practicing superstitions. This, in turn, suggests why legalizing gambling might not fully capture the gains from the illegal market -operators and gamblers both prefer cheating, but this would be harder to hide in a legalized environment. Terms of use: Documents inWe illustrate the model, generate results, and verify them empirically, using the example of jueteng, an illegal numbers game in the Philippines.

Existing formal models show that remittances generate a resource curse by allowing the government to appropriate its revenues toward rents, rather than public good provision. Households spend their remittance income on public-good substitutes, thereby alleviating the pressure on the government to provide public goods. However, the process by which the government survives the implicit threat of political challengers remains unspecified. By explicitly modeling political competition, I show that there is actually no resource curse from remittances. When there are challengers who can threaten to replace the incumbent leader, the best that any challenger can do is to offer not to take advantage of households’ provision of public-good substitutes, which induces the incumbent to try to match the offer. In equilibrium, public good provision is independent of remittances. This result holds even when no challenger can credibly commit to maintaining her offer once she is in power.
