- Abstract
- Recent empirical findings (Bordalo et al., 2018, 2019; Greenwood et al., 2022) have vindicated the view thatsystemic risk in financial markets is also influenced by cognitive misperceptions about future economicdevelopments in addition to being influenced by financial frictions. Most of the literature on macroprudentialregulation, nonetheless, has omitted those misperceptions and instead has derived policy implicationsassuming rational expectations. In this article (which is based on Camous and Van der Ghote, 2021), weexamine the joint implications of external financing frictions and extrapolative expectations for the stability ofthe financial system and the appropriate conduct of macroprudential regulation. We find that interactionsbetween those two elements exacerbate financial instability relative to the rational benchmark. This calls fortighter macroprudential regulation, even when the regulator is also subject to cognitive misperceptions.Disagreement about the appropriate macroprudential regulation among potential regulators with differingdegrees of misperception is stronger during booms, when risk-taking in financial markets and in realinvestments is more aggressive.

- Abstract
- Swift changes in investors' sentiment, such as the one triggered by COVID-19 global outbreak in March 2020, lead to financial tensions and asset price volatility. We study the interactions of behavioral and financial frictions in an environment with endogenous risk-taking and capital accumulation. Agents form diagnostic expectations about future stochastic outcomes: recent realizations of aggregate shocks are expected to persist. This behavioral friction gives rise to sentiment cycles with excessive investment and occasional safety traps. The interactions with financial frictions lead to an endogenous amplification of financial instability. We discuss implications for policy interventions.
