Pluralism, The Lucas Critique, And The Integration Of Macro And Micro, Peter Skott

Peter Skott

Mainstream macroeconomics has pursued micro founded models based on the explicit optimization by representative agents. The result has been a long and wasteful detour. But elements of the Lucas critique are rele- vant, also for heterodox economists.

Mainstream macroeconomics has pursued .micro founded.models based on the explicit optimization by representative agents. The result has been a long and wasteful detour. But elements of the Lucas critique are relevant, also for heterodox economists. Challenging common heterodox views on microeconomics and formalization, this paper argues that (i) economic models should not be based purely on empirically observed regularities,(ii) heterodox economists must be able to tell an integrated story about goal-oriented micro behavior in a specific macro environment, and (iii)relatively simple analytical models have an essential role to play.
