In this paper, I review the literature on rational choice theory to scrutinize a number of criticisms that philosophers have voiced against its usefulness in economics. The paper has three goals: first, I argue that the debates about RCT have been characterized by disunity and confusion about the object under scrutiny, which calls into question the effectiveness of those criticisms. Second, I argue that RCT is not a single and unified choice theory—let alone an empirical theory of human behavior—as some (...) critics seem to suppose. Rather, there are several variants of RCT used in economics. Third, I propose that we think of RCT as a set of distinct research strategies to appreciate its diversity. This account implies that the effectiveness of any criticism depends on the variant of RCT we are considering. (shrink)

The repercussion of Imre Lakatos’s methodology in economics has passed through quite different periods. His influence can be seen in discussions that affect economics as basic science (“positive economics”) and applied science (“normative economics”). This study examines the main lines of this historical trajectory and makes a critical analysis of the evolution of its repercussions on economic methodology. Starting with the initial period of promising attitude (1972–74), the analysis moves on through the middle period of more influence (1974–89) and then (...) turns to the critical stance of the later period (1989–). These steps provide a clear picture of strengths and weaknesses of the contributions of Lakatos’s methodology of scientific research programs to economic methodology. (shrink)
