This project investigates fundamental roles played by management and organizational practices in the determination of establishment/firm behaviors. Management and organizational practices and styles vary substantially across firms, industries and countries, and such heterogeneity is a source of variation in firm behaviors and market structures. Despite the importance of the roles of management and organizational practices, there are not many empirical investigations that explore such management roles by using large-scale data. The ultimate goal of this project is to discover various regularities regarding management practices and firm performances and provide useful insights into firm conducts/performances.
