We analyze the determinants of the origin of domestic and international terrorism in a large panel data set of 159 countries spanning from 1970 to 2007. We show that terror increases with GDP per capita, a higher polity score measuring a more open and competitive political system and experiences...

This paper investigates the effect of physicians on infant mortality, stillbirths and the incidence of common childhood diseases. We construct a new panel data set covering German municipalities from 1928 to 1936 based on historical sources. The endogeneity of health care supply is addressed by...

We conduct a field experiment to study if student counseling offices discriminate against disabled students based on their impairment. The offices receive randomized emails from fictitious high-school graduates, requesting information on the admission process and special accommodations to ease...

We investigate behavioral responses to a staggered disruption in the supply of prescription opioids across U.S. states: the introduction of electronic Prescription Drug Monitoring Programs (PDMPs). Using administrative datasets, we find PDMPs curtail the proliferation of prescription opioids....

This paper investigates the returns to health care provision during the mortality transition. We construct a new panel data set covering German municipalities from 1928 to 1936. The endogeneity of health care supply is addressed by using the expulsion of Jewish physicians from statutory health...

The existing literature on the determinants of terrorism treats terror as a uniform phenomenon and does not distinguish between different types of terror. This paper explicitly addresses the heterogeneity of terror by classifying groups according to their ideologies. We show that the pattern of...

Children starting school at older ages consistently exhibit better educational outcomes. In this paper, we underscore child development as a mechanism driving this effect. We study the causal effect of school starting age on a child's probability of developing special educational needs in early...
