While an individualist society prizes personal control, autonomy and individual accomplishments, a collectivist one puts a premium on loyalty and cohesion and imposes mutual obligations in the context of in-groups. It has been argued that, in contrast to collectivism, individualism will promote economic development directly by sharpening individual incentives to invest, innovate and accumulate wealth. In this article, I argue that the individualist–collectivist dimension can also affect development through its impact on the quality of government. The in-group favoritism inherent to collectivist societies is likely to engender corruption, nepotism and clientelism in the public sphere. In individualist societies, the relative weakness of in-group pressures and an emphasis on personal achievement and worth will contribute towards a more meritocratic and efficient public sector to the benefit of long-run growth. Empirical evidence is provided suggesting that insofar as individualism affects economic development it does so because it promotes good governance.
