In this paper, I first quickly recount the causes and consequences of the global financial crisis (GFC). Of course, the triggering event was the unfolding of the subprime crisis; however, I argue that the financial system was already so fragile that just about anything could have caused the...

Shadow banking is a broad concept. A possible definition is that it comprises non-bank institutions which undertake bank-like activities.

This paper surveys the literature on the linkages between asset prices and macroeconomic outcomes. It focuses on three major questions. First, what are the basic theoretical linkages between asset prices and macroeconomic outcomes? Second, what is the empirical evidence supporting these...

This paper surveys the theoretical and empirical literature on the macroeconomic implications of financial imperfections. It focuses on two major channels through which financial imperfections can affect macroeconomic outcomes. The first channel, which operates through the demand side of finance...

According to theory, market concentration affects the likelihood of a financial crisis in different ways. The “concentration-stability” and the “concentrationfragility” hypotheses suggest opposing effects operating through specific channels. Using data of 160 countries for the period...

We analyze the individual and macroeconomic impacts of heterogeneous expectations and action rules within an agent-based model populated by heterogeneous, interacting firms. Agents have to cope with a complex evolving economy characterized by deep uncertainty resulting from technical change,...

Textual analysis of the NBER Working Papers published during 1999-2016 is done to assess the effects of the 2007-2009 crisis on the academic literature. The volume of crisis-related WPs is counter-cyclical, lagging the financial-instability-index. WPs by the Monetary-Economics, Asset-Pricing,...

We study the economics and finance scholars' reaction to the 2008 financial crisis using machine learning language analyses methods of Latent Dirichlet Allocation and dynamic topic modelling algorithms, to analyze the texts of 14,270 NBER working papers covering the 1999–2016 period. We find...

The Basel III regulation explicitly prescribes the use of Hodrick-Prescott filters to estimate credit cycles and calibrate countercyclical capital buffers. However, the filter has been found to suffer from large ex-post revisions, raising concerns on its fitness for policy use. To investigate...
