Identifying a dominant firm's market power among sellers of a homogeneous product: an application to Alcoa


  • Sheng-Ping Yang


This paper measures the extent of Alcoa's (dominant firm) market power in the post-war US aluminium industry. An indirect procedure that combines estimation of the fringe supply elasticity, market demand elasticity, and extant market share data generates the estimate of Alcoa's residual demand elasticity which infers the firm's market power. Results show that Alcoa's market power declines with fringe's expansion.
