Strikes by unmanned aerial vehicles, or drones, have been the primary weapon used by the United States to combat the Taliban and Al-Qaeda in Afghanistan and Pakistan. This paper examines the dynamics of violence involving drone strikes and the Taliban/Al-Qaeda in Afghanistan and Pakistan from...

This paper describes the theoretical underpinnings and provides empirical evidence for a model that predicts a positive impact of immigration on entrepreneurial activity. Immigrants, we hypothesize, facilitate innovation and entrepreneurship by being willing and able to invest in new skills. At...

This paper documents where immigrants who enter the U.S. with different types of visas ("green cards") choose to live initially and what determines those location choices. Using population data on immigrants from the Immigration and Naturalization Service from 1971 to 2000, matched to data on...

Using recently-available data from the New Immigrant Survey, we find that previous selfemployment experience in an immigrant’s country of origin is an important determinant of their self-employment status in the U.S., increasing the probability of being self-employed by about 7 percent. Our...

This paper examines how violence in the Second Intifada influences Palestinian public opinion. Using micro data from a series of opinion polls linked to data on fatalities, we find that Israeli violence against Palestinians leads them to support more radical factions and more radical attitudes...

Geographic mobility is important for the functioning of labor markets because it brings labor resources to where they can be most efficiently used. It has long been hypothesized that individuals' migration propensities depend on their attitudes towards risk, but the empirical evidence, to the...

We provide a comparison of return to schooling estimates based on an influential study by Angrist and Krueger (1991) using two stage least squares (TSLS), limited information maximum likelihood (LIML), jackknife (JIVE), and split sample instrumental variables (SSIV) estimation. We find that the...

This paper studies the dynamics of violence in the Palestinian-Israeli conflict since the outbreak of the Second (or "Al-Aqsa") Intifada in September 2000, during which more than 3,300 Palestinians and more than 1,000 Israelis have been killed. The conflict has followed an uneven pattern, with...

While it is well known that some areas of the United States receive more immigrants than others, less is understood about the extent to which the character of immigration varies as well. There is much broader geographic variation in the skill and demographic composition of immigrants than...

In this paper we assess the effectiveness of suicide attacks and targeted killings in the Second Intifada. We find evidence that the targeted killings of Palestinian leaders by Israel reduce realized Palestinian violence. We find, however, that intended Palestinian violence is increasing at low...
