This temporality is well adapted to academia because searching for the truth is a very long-run objective. Policy-makers however do not have the luxury of a long time horizon, and would get much help from more big thinking in academia. Unfortunately, these different temporalities have an impact on economic thinking.
The typical methodology of economic theory is first to consider a frictionless benchmark, corresponding for instance to a long-run steady state equilibrium, and then enrich it with frictions. While this is understandable from a methodological point of view, this approach can easily imply a neglect of the short and medium-term dynamics, drastic adjustments and complexities that are important for central banks.
