We exploit exogenous variation in the risk of waterborne disease created by implementation of a major water reform in Mexico in 1991 to investigate impacts of infant exposure on indicators of cognitive development and academic achievement in late childhood. We estimate that a one standard...

This paper investigates the potential of an infant intervention to improve life expectancy, contributing to emerging interest in the early life origins of chronic disease. We analyse a pioneering program trialled in Sweden in the 1930s, which provided information, support and monitoring of...

We exploit the introduction of sulfa drugs in 1937 to identify the causal impact of exposure to pneumonia in infancy on later life well-being and productivity in the United States. Using census data from 1980-2000, we find that cohorts born after the introduction of sulfa experienced increases...

We study the social interaction of non-smokers and smokers as a sequential game, incorporating insights from social psychology and experimental economics into an economic model. Social norms affect human behavior such that non-smokers do not ask smokers to stop smoking and stay with them, even...

We present a theory on migration of dual-earner couples, and test it in the context of international migration. Our model predicts that the probability that a couple emigrates increases in the earnings of the primary earner. The effect of the earnings of the secondary earner may go either way....

We present a theory on migration of dual-earner couples and test it in the context of international migration. Our model predicts that the probability that a couple emigrates increases in the home-country earnings of the primary earner. The effect of the home-country earnings of the secondary...

Using Finnish panel data, we study how entrepreneurs differ from workers in education and income dynamics. We find that workers have higher median income in all educational groups. Without additional controls, entrepreneurs have higher average income with all but undergraduate level of...

We analyze the topical question of how the compensation of elected politicians affects the set of citizens choosing to run. To this end, we develop a sparse and tractable citizen-candidate model of representative democracy with ability differences, informative campaigning and political parties....

Katz and Rapoport (2005) conclude that with linear production technology and the possibility of unilateral migration, region-specific shocks may increase the average level of education. Previously, Poutvaara (2000) derived a corresponding result with Cobb-Douglas technology and migration which...
