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)
