Evaluating the Effectiveness of Government Intervention in Internalizing Negative Externalities of Production: A Case Study of Peabody Energy's Environmental Pollution

This commentary evaluates whether a court-imposed fine on Peabody Energy effectively internalizes the negative externality of production resulting from coal mine pollution. Using microeconomic frameworks, the author analyzes the divergence between marginal private cost (MPC) and marginal social cost (MSC) to illustrate market failure and welfare loss.

The analysis employs price-quantity diagrams to demonstrate how government intervention shifts the supply curve to reduce overproduction. The author argues that the fine's small magnitude relative to corporate revenue renders it an inadequate deterrent. The work is distinguished by its critical evaluation of one-off penalties versus recurring regulatory taxes and the proposal of alternative policy instruments like pollution permits.
