This paper studies the relationship between civil war and HIV/AIDS in Burundi. It contributes to the empirical literature by providing micro level evidence using an identification strategy based on original data on the dynamics of rebel movements. The presence of exit and entry points from and...

This paper employs a natural field experiment in the Netherlands to test whether individuals intuitively help strangers with different group identities. We implement time manipulations in an everyday task to stimulate intuitive versus deliberate decision-making and thereafter examine helpfulness...

The ongoing financial crisis so far cost the German financial sector 38 billion Euros due to losses on its mortgage-related subprime bank exposures. This paper looks for the impact of these losses on the real sector of the economy. First, the financial sector is looked at as part of the overall...

We test whether humans are intuitively inclined to cooperate with or punish strangers using a natural field experiment. We exogenously vary the time available to help a stranger in an everyday situation. Our findings suggest that subjects intuitively tend to help but behave more selfishly as...

This paper uses a field experiment to study the effect of perceived gender norms on the motherhood penalty in the Indian labor market. We randomly reported motherhood on fictitious CVs sent to service sector job openings. We generated exogenous variation in gender norms by prominently signaling...

This paper studies the relationship between civil war and HIV/AIDS in Burundi. It contributes to the empirical literature by providing micro level evidence using an identification strategy based on original data on the dynamics of rebel movements. The presence of exit and entry points from and...

This paper estimates the causal impact of landmines on child health and household expenditures in Angola by exploiting geographical variations in landmine intensity. We generate exogenous variation in landmine intensity using the distance between communes and rebel headquarters. As predicted by...

This paper tests the generalized Trivers Willard hypothesis, which predicts that parents with heritable traits that increase the relative reproductive success of males compared to females will have relatively more males than females. As in Kanazawa (2005) we test if taller mothers have...
