Abstract
We document that companies face a highly fragmented regulatory environment, where multiple agencies regulate overlapping aspects of their operations. We develop a novel measure of regulatory fragmentation that captures the extent to which a firm’s activities are regulated by multiple agencies. Firms with higher fragmentation have lower valuations and invest less. Using regulatory reforms that consolidated oversight responsibilities as a natural experiment, we show that reductions in fragmentation lead to increases in firm value and investment. The effects are stronger for firms with higher ex-ante fragmentation. Our results highlight the costs of regulatory complexity and the benefits of regulatory coordination.
