Understanding unethical behavior is essential to many phenomena in the real world. We carry out a field experiment in a unique setting that varies the levels of reciprocity and guilt in an ethical decision. A survey more than one year before the field experiment allows us to compare at the individual level stated unethical behavior with revealed behavior in the same situation in the field. Our results indicate a strong discrepancy between stated and revealed behavior, regardless of the specific treatment in the field experiment.

In empirical studies, survey questions are typically used to measure trust; trust games are also used to measure interpersonal trust. In this paper, we measure trust in different institutions by using both trust games and survey questions. We find that generalized trust is only weakly correlated with trust in specific institutions, when elicited both by using a trust game and by using survey questions. However, the correlation between trust in a specific institution elicited through a trust game and stated trust for the same institution is stronger and statistically significant.

The intense debate on the effectiveness of the war on drugs contrasts with the scarce quantitative evidence on its impacts on drug cultivation decisions by individual producers. Using panel data from an original survey of farmers living in coca-growing areas in Colombia, we evaluate the effectiveness of forced eradication policies implemented between 2000 and 2005. We find that one additional hectare eradicated decreases coca supply by 0.44 hectares, indicating that coca can only be eradicated at a very high cost.

Institutions play a significant role in stabilising large-scale cooperation
in common pool resource management. Without restrictions to govern human
behaviour, most natural resources are vulnerable to overexploitation. This study
used a sample size of 336 households and community-level data from 30 communities
around Gonarezhou National Park in Zimbabwe, to analyse the relationship
between institutions and biodiversity outcomes in community-based wildlife
conservation. Our results suggest a much stronger effect of institutions on biodiversity

In this paper, we identify economic implications of the pressure to share resources within a social network. Through a set of field experiments in rural Tanzania we randomly increased the expected harvest of the treatment group by the assignment of an improved and much more productive variety of maize.
