Abstract

Classical accounts of financial crises emphasize the joint contribution of extrapolative beliefs and leveraged risk-taking to financial instability. This paper proposes a simple macro-finance framework to evaluate these views. We find a novel interplay between non-rational extrapolation and investment risk-taking that amplifies financial instability relative to a rational expectation benchmark. Furthermore, the analysis provides guidance on the design of cyclical policy intervention. Specifically, extrapolative expectations command tighter financial regulation, irrespective of the regulator's degree of non-rational extrapolation.
