Price-cost margins and bid shading are affected by the parameters of the information structure: supply functions are steeper …A finite number of sellers (n) compete in schedules to supply an elastic demand.

A Bayesian supply function equilibrium is characterized in a market where firms have private information about their … uncertain costs. It is found that with supply function competition, and in contrast to Bayesian Cournot competition …, competitiveness is affected by the parameters of the information structure: supply functions are steeper with more noise in the …
