The slave trades out of Africa represent one of the most significant forced migration experiences in history. In this paper I illustrate their long-term consequences. I first consider the influence of the slave trade on the "sending" countries in Africa, with attention to their economic,...

Indicators for quality of schooling are not only relatively new in the world but also unavailable for a sizable share of the world's population. In their absence, some proxy measures have been devised. One simple but powerful idea has been to use the schooling premium for migrant workers in the...

In many environments, tournaments can elicit more effort from workers, except perhaps when workers can sabotage each other. Because it is hard to separate effort, ability and output in many real workplace settings, the empirical evidence on the incentive effect of tournaments is thin. There is...

One in nine people between the ages of 18 and 64 in the US, and every second foreign-born person in this age bracket, speaks Spanish at home. And whereas around 80 percent of adult immigrants in the US from non-English speaking countries other than Mexico are proficient in English, only about 50...

For years, anecdotal evidence has suggested increased fertility rates resulting from catastrophic events in an area. In this paper, we measure this fertility effect using storm advisory data and fertility data for the Atlantic and Gulf Coast counties of the United States. We find that...

Exogenous shocks often impact a local labor market more than at the national level. This study improves upon the standard Difference in Difference (DD) approach by examining exogenous shocks using a Generalized Difference in Difference (GDD) econometric approach that identifies the effects of...

After nearly a full century of decline, the Labor Force Participation Rate (LFPR) of older men in the United States leveled off in the 1980s, and began to increase in the late 1990s. We use a time series of cross sections from 1962 to 2005 to model the LFPR of men aged 55-69, with the aim of...

In the 1980s the composition of immigrants to the U.S. shifted towards less-skilled workers. Around this time, real wages and employment of younger and less-educated U.S. workers fell. Some blame recent immigration shifts for the misfortunes of unskilled workers in the U.S. OLS estimates using...

This study provides the first nation-wide analysis of the labor market implications of occupational licensing for the U.S. labor market, using data from a specially designed Gallup survey. We find that in 2006, 29 percent of the workforce was required to hold an occupational license from a...

We develop a new general equilibrium model of trade with heterogeneous firms, variable demand elasticities and endogenously determined wages. Trade integration favors wage convergence, intensifies competition, and forces the least efficient firms to leave the market, thereby affecting aggregate...
