2008 AEC - Can Corruption Be Studied in the Lab? Comparing a Field and a Lab Experiment
This paper makes an attempt at testing the external validity of corruption experiments by moving from the lab in a developed country, to where it matters the most, the Öeld in a developing country. In our experiment a candidate proposes a bribe to a grader in order to obtain a better grade. We Önd the direction and the magnitude of most treatment e§ects to be statistically indistinguishable between the lab and the Öeld. In particular, increasing the gradersíwage reduces in both environments the probability to accept the bribe. Finally, we identify several micro-determinants of corruption (age, religiousness, ability).
