Impact evaluations

These are final reports of 3ie-supported impact evaluations that assess the difference a development intervention has made to social and economic outcomes. We fund rigorous evaluations that include a theory-based experimental or quasi-experimental design, and we use the most appropriate mix of methods to capture outcomes and answer what works, for whom, why and at what cost.

Truth telling by third-party audits and the response of polluting firms: Experimental evidence from India

Impact evaluation 3ie

2013

How accurate and credible is an environmental audit if the auditor is chosen and paid for by the firm being audited? In this 3ie-supported impact evaluation report, Esther Duflo, Michael Greenstone, Rohini Pande and Nicholas Ryan provide a clear answer. Their impact evaluation of an environmental audit scheme in Gujarat shows such an arrangement encourages corruption and misreporting of industrial plant emissions.
