Strategic communication with reporting costs

A decision maker relies on information of parties affected by her decision. These parties try to influence her decision by selective disclosure of facts. As is well known from the literature, competition between the informed parties constrains their ability to manipulate information. We depart from this literature by introducing a cost to communicate. Our parties trade off their reporting cost against the effect on the decision. Some information is never revealed. In contrast to setups without communication costs, our decision maker can benefit by ex ante committing to an ex post suboptimal decision rule. Moreover, committing ex ante not to listen to one of the parties may also be beneficial for the decision maker.

     

Subgame-Perfect Punishment for Repeat Offenders

First I show that for wealth-constrained agents who may commit an act twice the optimal sanctions are the offender's entire wealth for the first and zero for the second crime. Then I ask the question whether this decreasing sanction scheme is subgame perfect (time consistent), that is, does a rent-seeking government stick to this sanction scheme after the first crime has occurred. If the benefit and/or the harm from the crime are not too large, this is indeed the case; otherwise, equal sanctions for both crimes are optimal.     

PENALTY STRUCTURES AND DETERRENCE IN A TWO‐STAGE MODEL: EXPERIMENTAL EVIDENCE

Multiperiod models of criminal enforcement based on the standard economic approach of Becker (1968) generally find that the optimal penalty structure is either flat or declining. We present the first experimental test of a two‐stage theoretical model that predicts decreasing penalty structures will yield greater deterrence than increasing penalty structures. This prediction is based on the belief that if the penalty for the first offenses is sufficiently low, the agent should commit the offense and continue to offend if undetected. Our results are consistent with the theoretical prediction that decreasing fine structures are more effective at reducing risky behavior. (JEL C91, K42, K10)
