Market Failures and Official Sector Interventions
In the United States and other free market economies, the official sector typically has minimal involvement in market activities absent a clear rationale to justify intervention, such as a market failure. In this post, we consider arguments for official sector intervention, focusing on the market failure arising from externalities related to business closures. These externalities are likely to be particularly high for closures arising from pandemic-related economic disruptions. We discuss how the official sector, including institutions such as Congress and the Treasury, can increase social welfare by acting to minimize the fixed costs of business start-up and failure, including the costs associated with unemployment, beyond the level set by private markets alone.
