We introduce a theoretical model of the active fund management industry (AFMI) in which performance and size depend on the AFMI's competitiveness (concentration). Under plausible assumptions, as AFMI's concentration decreases, so do fund managers’ incentives for exerting effort in search of alpha. Consequently, managers produce lower gross alpha, and rational investors, inferring lower expected AFMI performance, allocate a smaller portion of their wealth to active funds. Empirically, we find that a decrease in the US mutual fund industry concentration over our sample period is associated with a decrease in its net alpha and size (relative to stock market capitalization).

We introduce political tournament “participation/inclusion” games. Dominant strategies determine whether players choose to compete by enhancing economic performance. Unique Nash equilibria competitors win (only) inclusion as promotion candidates. We find empirical justification for such equilibria in Chinese province heads' periodic political tournaments/elections for promotion to the Communist Party politburo and government positions. We document pervasive tournament-synchronized corporate decision-making cyclicality. Firms enhance economic performance by increasing investments, taxes, and employment before elections. Cyclicality is dominantly driven by privately-owned enterprises, is weaker in economically/politically weak(strong) provinces. Political promotions, however, are not sensitive to corporate investments enhanced before tournaments but to long-run investments.
