We consider the problem of estimating and decomposing wage differentials in the presence of unobserved worker, firm, and match heterogeneity. Controlling for these unobservables corrects omitted variable bias in previous studies. It also allows us to measure the contribution of unmeasured...

I conducted an artefactual field experiment to identify whether guilt reduces crime, and how the crime reduction effects of guilt change due to peer effects. Guilt aversion predicts the occurrence of peer effects caused by changes in guilt sensitivity and belief. I found supporting evidence of...

The present study is, in particular, an attempt to test the relationship between tax level and political stability by using some economic control variables and to see the relationship among government effectiveness, corruption, and GDP. For the purpose, we used the Vector Autoregression (VAR)...

This paper examines the effect of peers on individual risk taking. In the absence of informational motives, we investigate why social utility concerns may drive peer effects. We test for two main channels: utility from payoff differences and from conforming to the peer. We show experimentally...

Zimbabwean villagers of distinct background have resettled in government organized land reforms for more than three decades. Against this backdrop, I assess the level of social cohesion in some of the newly established communities by estimating average preferences for fairness in a structural...

We report a framed field experiment, in which we study the effectiveness of punishment and reward in sustaining cooperation in a social dilemma. Punishments tend to be directed at non-cooperators and rewards are assigned by those who are relatively cooperative. In contrast to the results...

We conduct a field experiment to measure cooperation among groups of recreational fishermen at a privately owned fishing facility. The parameters are chosen so that group earnings are greater when group members catch fewer fish, as in the Voluntary Contributions Mechanism (VCM). In a manner...

This paper examines the issue of whether workers learn productive skills from their co-workers, even if those skills are unethical. Specifically, we estimate whether Jose Canseco, a star baseball player in the late 1980’s and 1990’s, affected the performance of his teammates by introducing...

We analyse peer effects among students of a middle-sized Italian public university. We explain students’ average grade in exams passed during their Second Level Degree course on the basis of their pre-determined measures of abilities, personal characteristics and peer group abilities. Thanks...

We conducted a multi-wave field experiment to study the interaction of peer effects and self-control among undergraduate students. We use a behavioral measure of self-control based on whether students achieve study related goals they have set for themselves. We find that both self-control and...
