Abstract
Regulatory impact assessment (RIA) involves a systematic appraisal of the costs and benefits associated with a proposed new regulation and evaluation of the performance of existing regulations. So far, most academic research has been concerned with the adoption of RIA in OECD countries. This article assesses the contribution that RIA can make to ‘better regulation’ in developing and transition economies. The results reported in this article suggest that a growing number of low and middle-income countries are beginning to apply some form of regulatory assessment, but that the methods adopted are partial in their application and are not systematically applied across government. The authors discuss the implications of their findings for capacity building and future research.
