This paper treats racial integration as an innovation in economic process in which economic entities find it advantageous to utilize potentially more productive inputs previously unavailable due to law, custom, or managerial discretion. Data on the racial integration of Major League Baseball and Atlantic Coast Conference basketball are employed to address this issue. The central question examined is which type of team integrated first—losers or winners? The results strongly support the idea that entrepreneurship trumps competitive rivalry; that is, winning teams led the process of racial integration.

This paper seeks to explain the initial successes and failures of Protestantism on economic grounds. It argues that the medieval Roman Catholic Church, through doctrinal manipulation, the exclusion of rivals, and various forms of price discrimination, ultimately placed members seeking the Z good “spiritual services” on the margin of defection. These monopolistic practices encouraged entry by rival firms, some of which were aligned with civil governments. The paper hypothesizes that Protestant entry was facilitated in emergent entrepreneurial societies characterized by the decline of feudalism and relatively unstable distribution of wealth and repressed in more homogeneous, rent‐seeking societies that were mostly dissipating rather than creating wealth. In these societies the Roman Church was more able to continue the practice of price discrimination. Informal tests of this proposition are conducted by considering primogeniture and urban growth as proxies for wealth stability.
