The question that how market structure and innovation are related has been extensively studied in the literature. However, there is hardly any notable study on this question for the global automobile industry. We fill this gap by studying the relationship between market structure and innovation in the global automobile industry for the 1980-2005 period. We use the dynamic industry framework of Ericson and Pakes (Review of Economic Studies, 1995) and estimate the parameters of the model using a two-step procedure proposed by Bajari et al (Econometrica, forthcoming). Since the global auto industry has seen a lot of consolidation since 1980, mergers are an important ingredient of our model. After estimating the parameters of the model, we simulate the industry forward and study how changing market structure (mainly due to mergers) affects innovative activity at the firm as well as the industry level. Our findings are the following. (1) The effect of market structure on innovation in the global auto industry depends on the initial state of the industry. If the industry is not very concentrated, as it was in 1980, some consolidation may increase the innovative activity. However, if the industry is already concentrated, as in 2005, further consolidation may reduce the innovation incentives. (2) Mergers reduce the value of merging firms though they may increase the aggregate value of the industry. (3) Mergers between big firms eventually reduce consumers' utility.
