Prosocial banks avoided panic runs despite weak fundamentals. We show that socially responsible investments deter panic runs in any global game with nonrival public goods, even if every depositor is atomistic, rational, and selfish. We study financial and social impacts of divestment in our tractable framework. Divestments generate financial gains whenever they positively assort the public goods from bank investments and the depositors’ sensitivity to those goods. Such divestments can nonetheless harm welfare. Our results rationalize the divestment policies seen in practice, and caution against their potentially harmful social impact.
