Article dans une revue: Globalization has been accompanied by rising pressure from advocacy non-governmental organizations (NGOs) on multinational firms to act in socially-responsible manner. We analyze how NGO pressure interacts with industry structure, using a simple model of NGO-firm interaction embedded in an industry environment with endogenous markups and entry. We explain three key empirical patterns in developing-country industries under activist pressure: the degree of exit under more intense activist pressure, the differential response of industries to NGO activism, and the general rise of NGO activism following globalization.
