We describe the demand for interns in the U.S. using ads from an internship-specific website. We find that internships are more likely to be paid when more closely associated with a specific occupation, when the local labor market has lower unemployment, and when the local and federal minimum...

his 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...

In an important and provocative paper, `Does Compulsory School Attendance Affect Schooling and Earnings?', Angrist and Krueger use quarter of birth as an instrument for educational attainment in wage equations. To support a causal interpretation of their estimates, they argue that compulsory...

In this paper we draw attention to two problems associated with the use of instrumental variables (IV) whose importance for empirical work has not been fully appreciated. First, using potential instruments that explain little of the variation in the: endogenous explanatory variables can lead to...
