This paper discusses the econometric model of causal policy analysis and two alternative frameworks that are popular in statistics and computer science. By employing the alternative frameworks uncritically, economists ignore the substantial advantages of an econometric approach, resulting in less informative analyses of economic policy. We show that the econometric approach to causality enables economists to characterize and analyze a wider range of policy problems than alternative approaches.
