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...

In 1997 GDP per capita in East Germany was 57% of that of West Germany, wage rates were 75% of western levels, and the unemployment rate was at least double the western rate of 7.8%. One would expect that if capital flows and trade in goods failed to bring convergence, labor flows would respond,...

I examine the determinants of inter-state migration of adults within western Germany, using the German Socio-Economic Panel from 1984 - 2000. I highlight the prevalence and distinctive characteristics of migrants who do not change employers. Same-employer migrants represent 25 % of all migrants,...

Germany experienced an even deeper fall in GDP in the Great Recession than the United States with little employment loss. Employers’ reticence to hire in the preceding expansion - associated in part with a lack of confidence it would last - contributed to an employment shortfall equivalent to...

Following monetary union with west Germany in June 1990 the median real monthly wage of prime age east German workers rose by 83% in six years. I use the German Socio-Economic Panel data to investigate the determinants of this wage growth and some of its implications. For the 1990-1991 period I...

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...

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...

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’...
