Punishing the Innocent along with the Guilty: The Economics of Individual versus Group Punishment

Standard models of law enforcement involve the apprehension and punishment of a single suspect, but in many contexts, punishment is actually imposed on an entire group known to contain the offender. The advantages of .group punishment. are that the offender is punished with certainty and detection costs are saved. The disadvantage is that innocent individuals are punished. We compare individual and group punishment when social welfare depends on fairness, and when it depends on deterrence. We show that group punishment may dominate in the former case if the detection technology is ineffective but never in the latter case. We discuss our results in the context of several examples.

Ethnicity, Governance and the Provision of Public Goods

Ethnicity is an important institution and one that impacts on the quality of governance. This paper focuses on the behavior of ethnic groups and specifically on their impact on the provision of public goods. The paper shows that ethnic heterogeneity results in under-provision of non-excludable public goods. On the other hand, such societies associate with provision of patronage goods. The paper proposes some areas of research such the economics of ethnic institutions, empirical evidence of the role ethnic groups on public goods provision, tax compliance and institutional reforms to improve governance.
