Rationality, Power, Management and Symbols: Four Images of Regulatory Impact Assessment

Impact assessment is the pivotal instrument in the recent wave of regulatory reforms labeled ‘better regulation’. Although the economics of impact assessment has been the subject of a vast literature, less is known about its political properties. Within a comparative framework, this article provides conjectures on four images of impact assessment – that is, rational policy making, political control of the bureaucracy, public management reform, and symbolic action. Looking at six countries with a long experience of impact assessment and the European Union, the article first builds expectations about the diffusion of the images across countries, and then proceeds to measurement by using both objective and interpretative/subjective indicators. The findings seem to support the public management reform image – a conclusion that suggests further specifications about administrative traditions and change. Sweden and Denmark are not using impact assessment to foster instrumental rationality or increase the political control of bureaucracies and, together with the Netherlands, rank high on the symbolic action scale. The United States – and to a lesser extent Canada and the United Kingdom – have a multi‐purpose approach to impact assessment. The case of the European Union defies prior expectations, showing much more usage than anticipated.
