论文摘要:

Firms can learn about new technologies from other adopters, though they do not always exploit this form of social learning. We examine whether shale gas operators took advantage of environmentally-focused disclosure laws to learn from competitors and improve productivity; with this information, we evaluate the claim that chemical disclosure rules expose valuable trade secrets. We exploit an unusual regulatory episode in Pennsylvania that allows us to see chemical inputs prior to public disclosure. Using detailed data on well-level inputs and outputs, we study how the change in disclosure regime affected operators' chemical use and well productivity.
