Abstract
This research attempts to observe competitive behaviors in a multiple reaction-multimarket setting. Competition is treated as the game of exerting price and product decision variables in several markets. The products sold in the markets are partial substitutes for each other. The interaction between a firm and its rivals is represented by a set of price and product conjectures, which represents the firm's belief about rivals' responses against its decision changes. The U.S. automobile industry is used to examine the interaction. By estimating the competitive conjectures, diverse patterns of competition are found among the U.S. automobile producers. In general, firms are more cooperative in price games than in product games and more cooperative in highly profitable markets than in less profitable markets. Market share is found to have effect on within-market price conjectures but no effect on product conjectures.
