Towards evidence based policy

The effects of policy interventions are often unknown. Policy experiments offer opportunities to find convincing evidence about the impact of policy.

This paper studies the pros and cons of controlled and natural policy experiments in the search for evidence of policy effectiveness. It concludes that controlled policy experiments are appropriate to deliver evidence on policy matters that have dragged on for a long time. Furthermore, it argues that many opportunities to provoke natural experiments in standard policy making exist, and that capture of these opportunities will increase our knowledge about policy effects importantly.
