The normative decision theory in economics: a philosophy of science perspective. The case of the expected utility theory

摘要

This article analyses how normative decision theory is understood by economists. The paradigmatic example of normative decision theory, discussed in the article, is the expected utility theory. It has been suggested that the status of the expected utility theory has been ambiguous since early in its history. The theory has been treated as descriptive, normative, or both. This observation is the starting point for the analysis presented here. The text discusses various ways in which economists and philosophers of economics have conceptualized the normative status of the expected utility theory, and it shows that none is satisfactory from the point of view of philosophy of science.
