When an individual believes that peers are predominantly untruthful in a given situation, is he/she more likely to be untruthful in that situation? We study this question in deception experiments patterned after Gneezy [Gneezy U. “Deception: The Role of Consequences.” American Economic Review, 95, 2005, 384–94] and conducted in Arizona, California, and India. We find evidence that dishonesty is indeed contagious. (JEL D03)

Does local Federal regulation respond to the preferences of local Congressional representatives? For example, do Republican Congressmen reduce local enforcement of Clean Air laws in their districts? We use facility-level panel data on Clean Air Act inspections over 1989-2005 to study the causal effect of a Congressman's party affiliation on local enforcement. Random assignment of electoral outcomes is obtained with a Regression Discontinuity design. We find that new Republican (vs. Democratic) Representatives significantly depress inspection rates for local polluting facilities in the first year after their election. (JEL D73, Q52, Q53)

On Monetary and Non-Monetary Interventions to Combat Corruption 1The paper studies the relative effectiveness of extrinsic monetary disincentives and intrinsic non-monetary disincentives to corruption. In doing so, we also test the Beckarian prediction that at the same level of expected payoff, a low probability of detection with high penalty is a stronger deterrent to corruption than a high probability of detection with low penalty.In Experiment 1, two treatments are designed to study the effect of a low probability of detection with high penalty, and a high probability of detection with low penalty, on bribe taking behavior in a harassment bribery game. In Experiment 2, subjects participate in the same baseline harassment bribery game either without or after having gone through a four-week ethics education program. Results show that a) a low probability of detection with high penalty reduces both the amount and the likelihood of bribe demand, b) a high probability of detection with low penalty has no effect on bribe demand behavior, c) normative appeals of ethics education has a small effect on the likelihood but not on the amount of bribe demand, when measured immediately after the intervention, d) the effect of ethics education vanishes when measured four weeks after the intervention, e) extrinsic monetary intervention, particularly low probability of detection with high penalty, is m...
