This study analyzes the relationship between market concentration and new product introductions using an extensive annual panel data set covering the period 1983 to 2004 from the US processed food industry. We test the new theory, which argues that new product introductions are influenced by the anticipation of future mergers. The evidence suggests that market concentration increases new product introductions and product introductions spur subsequent mergers in the US processed food industry. Hence it provides evidence in support of the anticipatory mergers theory
