Many corporate ESG disclosure regulations rely on private activist pressure to enforce compliance, but relatively little is known about its effectiveness. We present results from a field experiment testing the effect of various types of pressure from a leading human rights NGO on subsequent corporate compliance with the U.K. Modern Slavery Act of 2015, a law requiring disclosure of actions taken to address human rights issues. Sending firms a letter describing their legal ESG disclosure obligations had an unexpected effect of reducing rather than increasing compliance. This effect was partly mitigated for firms whose letter additionally included a list of already compliant firms, the mitigating effect being greatest when this list of peers was drawn from the same geographic location as the targeted firm.
