According to advocates, eco-certification can improve developing country farmers' environmental and economic performance. However, these notional benefits can be undercut by self-selection: the tendency of relatively wealthy farmers already meeting eco-certification standards to...

From 1997 to 2005, an astonishing 5,200 million USD was invested to reduce cocaine production in Colombia, the world’s main cocaine producer. However, little is known about the effectiveness of policies targeting coca cultivation. This paper uses a surveybased experiment to evaluate the...

We study behavior in a search experiment where sellers receive randomized bids from a computer. At any time, sellers can accept the highest standing bid or ask for another bid at positive costs. We find that sellers stop searching earlier than theoretically optimal. Inducing a mild form of time...

Laboratory experiments are potentially effective tools for studying behavior in settings where little or no information would otherwise exist such as participation in illicit activities. However, using laboratory experiments to draw policy recommendations is highly debatable. We investigate the...

This paper investigates the hypothesis that women are underrepresented in leadership roles due to a lower ability to influence others. By comparing societies that differ in the inheritance rights of men and women, we trace the origins of such difference. The results of a public good game with...

To study the persistence of cultural norms that mandate respect towards the elder, we conducted an artefactual field experiment in two cities in Ghana. Using a public good game with third-party punishment, we find that punisher's age is an important determinant of cooperation. Our results...

This paper explores the impacts of traditional agricultural insurance that offers protection against climatic shocks on small-scale tobacco farmers in Colombia. We analyze the impacts of access to the insurance on household financial outcomes after a period of severe climatic events that caused...

This paper investigates the efficiency of carrot and stick policies to reduce investment in coca cultivation in rural Colombia. To measure behavioral responses to anti-drug policies, we conducted a framed field experiment with farmers living in one of the most important coca growing areas. Our...
