Professor Doraszelski’s research identifies and explains the long-run impact of firms’ strategic decisions on the evolution of an industry. Many decisions such as investments in capacity and research and development are long-lived and affect both current and future profitability. They also have profound consequences for the competitive position of a firm vis-a-vis its rivals and shape the structure of the industry. These changes in industry structure in turn affect the future decisions of firms. Professor Doraszelski’s overarching research interest is to investigate, both theoretically and empirically, this two-way link between firms’ strategic decisions and the evolution of the industry over time. Professor Doraszelski’s research has been published in leading academic journals including the American Economic Review, Econometrica, the Journal of Political Economy, the Rand Journal of Economics, and the Review of Economic Studies. Professor Doraszelski is the recipient of numerous grants from the National Science Foundation. He was a National Fellow at the Hoover Institution at Stanford University from 2006 to 2007.
