This paper introduces groups that are in conflict against each other in law enforcement policy. These groups can have an effect on the process of law enforcement by making upfront investments, such as bribes. We also investigate consequences when a policy maker acts to maximize a bribe instead of social welfare. Thus, this paper presents an inclusive framework for incorporating private law enforcement, corruption and avoidance activities. This article shows that this competition can lead to moderate and more efficient law enforcement activities. This indicates that inefficient law enforcement by authority with harm reduction motivation can be avoided. Additionally, this paper shows that depending on the policy maker’s objection between rent-seeking motivation or social welfare maximizer, deterrence effects vary. This paper provides a clear mechanism that the rent-seeking motivated policy maker tends to set less severe enforcement policies than the social welfare level.
