The Economics of Trust

"Trust is not merely a social nicety - it is infrastructure. Across decades of empirical research, economists and political scientists have converged on a striking finding: societies and individuals with higher levels of interpersonal trust consistently outperform their low-trust counterparts on nearly every measurable dimension of economic and institutional life."

"High-trust societies can support deep cooperation without an overhead of control: a promise genuinely functions as a promise. Participation in financial markets depends strongly on generalized trust, and collaboration and governance are easier when trust is present."

"Trust can be destroyed from the outside - by deception, by institutional shocks, and by changes in incentive structures that quietly rewrite the norms governing how people treat one another. The most dramatic evidence of exogenous trust destruction comes from Nunn & Wantchekon (2011), whose landmark study traced the long shadow of the African slave trade."

Trust functions as economic infrastructure, significantly impacting growth and institutional quality. High-trust societies benefit from lower transaction costs, increased investment, and effective contract enforcement. Trust enhances participation in financial markets and facilitates collaboration. However, trust is fragile and can be undermined by deception, institutional shocks, and adverse incentives. Historical evidence shows that regions affected by the slave trade still exhibit lower levels of trust today, illustrating the long-term consequences of trust destruction.
