A contribution to scientific studies of norms in economics inspired by JN Keynes and Popper

This paper defends JN Keynes’s argument that normative economics can be objective. It begins by exploring Keynes’s view on the positive/normative distinction in economics. After discussing its originality and advantages, the paper recognizes that the Keynesian distinction does not explain the exact nature of the relationship between positive and normative economics. Thus, it tries to improve Keynes’s position using Popper’s contributions to economics. It shows that for Popper, advances in normative social science are the main steppingstone to resolving disagreements over the choice of the norms underlying the reform of social situations. The final two parts of the paper draw on the contributions of Keynes and Popper to the study of norms to explain why normative economics can more easily approach objectivity by concentrating on highly delimited topics. The last part relies on Popper’s concept of avoidable unhappiness to offer one method of restraining the tasks of normative economics.
