We analyze the optimal government response to food adulteration and mislabeling while accounting for heterogeneity in consumer preferences and producer efficiency, endogeneity in producer quality choices, and asymmetries in food fraud detection. When more-efficient producers commit fraud, the optimal policy response is a strict monitoring and enforcement system. For less-efficient producers, both increased certification costs and monitoring and enforcement can deter food fraud. When the government desires to increase average product quality, the optimal policy is strict monitoring and enforcement. Increasing monitoring and enforcement in the presence of corruption provides increased incentives for collusion between dishonest producers and corrupt policy enforcers.

This paper develops a model of heterogeneous individuals to analyze the interacting horizon and free-rider problems faced by cooperative organizations. Analytical results identify the conditions under which a cooperative will form despite these property rights problems and show that (i) differences in members’ time horizons need not necessarily lead to short-term cooperative investments and (ii) free riding is not always a problem for cooperatives. The analysis also shows how a cooperative can use a membership fee to address these property rights problems and provides additional insights into the relationship between a cooperative’s cost structure and membership fees.
