The United States has a teenage birth rate that is high relative to that of other developed countries, and falling more slowly. Children of teenagers may experience difficult childhoods and hence be more likely to commit crimes subsequently. I assess to what extent lagged teen birth rates can...

Using cross-country and Peruvian data, I show that victims of misfortune, particularly crime victims, are much more likely than non-victims to bribe public officials. Misfortune increases victims' demand for public services, raising bribery indirectly, and also increases victims' propensity to...

In this paper, I examine the role of household income in determining who bribes and how much they bribe in health care in Peru and Uganda. I find that rich patients are more likely than other patients to bribe in public health care: doubling household consumption increases the bribery...

We measure the extent to which skilled immigrants increase innovation in the United States by exploring individual patenting behavior as well as state-level determinants of patenting. The 2003 National Survey of College Graduates shows that immigrants patent at double the native rate, and that...

Using the 2003 National Survey of College Graduates, I examine how immigrants perform relative to natives in activities likely to increase U.S. productivity, according to the type of visa on which they first entered the United States. Immigrants who first entered on a student/trainee visa or a...

We provide a theoretical framework for understanding when an official angles for a bribe, when a client pays, and the payoffs to the client’s decision. We test this frame work using a new data set on bribery of Peruvian public officials by households. The theory predicts that bribery is more...

I examine the determinants of inter-state migration of adults within western Germany, using the German Socio-Economic Panel from 1984-2000. Migrants who do not change employers represent one-fifth of all migrants and have higher education and pre-move wages than non-migrants. Skilled workers...

Using cross–country and Peruvian data, I show that victims of misfortune, particularly crime victims, are much more likely than non–victims to bribe public officials. Misfortune increases victims’ demand for public services, raising bribery indirectly, and also increases victims’...

Using detailed Peruvian data measuring bribery, I assess which types of public official are most corrupt and why. I distinguish between the bribery rate and the size of bribes received, and seek to explain the variation in each across public institutions. The characteristics of officials’...

The popular belief that immigrants have a large adverse impact on the wages and employment opportunities of the native-born population of the receiving country is not supported by the empirical evidence. A 10 percent increase in the fraction of immigrants in the population reduces native wages...
