Public law enforcers and political competition

In this paper, we analyze how political competition affects the designof public law enforcement policies. Assuming that the cost of enforcement is linear, criminals'type is uniformally distributed, and society's wealth is large enough, the article arrives at two main conclusions: 1) electoral competition entails no loss of efficiency at equilibrium for both minor and major offenses (e.g. minor offenses are not enforced, while major ones are fully deterred); 2) different distortions arises at equilibrium for the intermediate offenses: enforcement expenditures for small offenses are lower than the optimal level, such that the issue of under-deterrence is exacerbated; in contrast, for larger offenses, enforcement measures are higher, and there is more deterrence than what efficiency requires. We show that these results also holds under more general assumptions (convex costs of enforcement, a general cdf of illegal bene.ts, a lower society's wealth), excepted that full deterrence of major offenses is not achievable.
