Paul Krugman once sardonically commented on how it is “hard to believe” that economists once celebrated the success of their research and the resultant policies. He wasn’t lying about the overwhelming positivity that surrounded economics less than a decade ago. Be it IMF’s Blanchard or Robert Lucas, they had all (mostly) believed that the big battles were behind them, that better policymaking, grounded in macroeconomics’ supposed phase of theoretical glory, had everything under control making depression prevention was a reality. Numbers and rhetoric substantiated these claims to a great degree and macroeconomics as an academic discipline (through the path-breaking research) and as the profession (through subsequent policy making) had been …show more content…

Firstly, the idea of conceptual reductionism or the focus on the micro-foundations of macroeconomic models lending back to the utility maximization decision of individual agents. This expresses strong predilection towards theoretical frameworks that attempt to describe the global economy in terms of an equilibrium asserting consistency in individual behaviors of different economic agents. Secondly, the rational agents assumption that further implies that economic agents have absolute understanding of macroeconomic models and can perfectly comprehend and forecast based on the information that they access, in terms of rational expectations. This assumption is especially supported by and enshrined within larger analytic models such as the Dynamic Stochastic General Equilibrium models (DSGE-models) that are now commonly used tools for policymaking.

When the crisis settled in beyond reasonable doubt, the economists, actively involved with governments across Europe, had recognized the problems with the standard models. Flagging a temporary solution is, however, an ineffective fix for a poor model as sound theoretical frameworks are pre-requisite to making empirical sense and by extension, to policymaking and regulation. Abandoning existing models and resorting to common sense policies at times of crisis is, therefore, not the solution but building models that could accommodate the crisis
