John C. Panzar

John C. Panzar was an economist known for his work in industrial organization and market structure analysis. He developed the "Panzar-Rosse Model," which helps determine how competitive a market is by examining how a firm's revenue responds to changes in input costs. The model uses economic data to distinguish between perfectly competitive markets, monopolies, and other market types, aiding regulators and policymakers in understanding market dynamics and promoting fair competition. Panzar's contributions provide valuable tools for analyzing how firms behave and how markets function.
