Understanding expectational coordination as a major intellectual challenge: The “eductive” guide line

Abstract

The paper puts emphasis on the so-called “eductive” approach for a critical assessment of the Rational Expectations hypothesis. Section 2 makes an intuitive unformal presentation, aimed at comparing the approach and the results of “eductive” learning and ”real time” learning in two polar models, (a two period partial equilibrium model and a simple Real Business Cycle mode). A segment of theoretical literature, taking an eductive view of stability in the fields of finance, trade, general equilibrium, short term or long term macroeconomics….is reviewed in Section 3.
