Using confidential microdata from the U.S. Census Bureau, we investigate the performance of Asian-owned businesses. Using regression estimates and a special nonlinear decomposition technique, we explore the role that class resources, such as financial capital and human capital, play in contributing to the relative success of Asian businesses. We find that Asian-owned businesses are more successful than white-owned businesses for two main reasons – Asian owners have high levels of human capital and their businesses have substantial startup capital. Using detailed information on both the owner and the firm, we estimate the explanatory power of several additional factors.
