This paper develops a Dynamic Stochastic General Equilibrium (DSGE) model to study how the instability of the banking sector can amplify and propagate business cycles. The model builds on Bernanke, Gertler and Gilchrist (BGG) (1999), who consider credit demand friction due to agency cost, but it...

The extraordinary events surrounding the Great Recession have cast a considerable doubt on the traditional sources of macroeconomic instability. In their place, economists have singled out financial and uncertainty shocks as potentially important drivers of economic fluctuations. Empirically...

Recoveries that occur in the absence of credit growth are often dubbed miracles and named after mythical creatures. Yet these are not rare animals, and are not always miracles. About one out of five recoveries is "creditless," and average growth during these episodes is about a third lower than...

This paper argues that counter-cyclical liquidity hoarding by financial intermediaries may strongly amplify business cycles. It develops a dynamic stochastic general equilibrium model in which banks operate subject to financial frictions and idiosyncratic funding liquidity risk in their...

The recent Financial Crisis reminded us once again about the vulnerability of the global economy. Economists were forced to think about the effectiveness of their policies. During this period, many governments across the world had adopted fiscal measures to boost their local economies. The path...

The purpose of this lecture is to look beyond the complex events that characterize the global financial and economic crisis, identify the basic mechanisms, and infer the policies needed to resolve the current crisis, as well as the policies needed to reduce the probability of similar events in...

In the U.S., over 1873-2014, an increase in bank credit is associated with a lower risk of a financial crisis in the near future. Bank credit expansion predicts lower excess returns and volatility for the aggregate stock market, and this predictive relation varies in the cross-section and is...

The prevailing narrative about the Great Recession is that it was caused by a financial crisis. This paper refutes that explanation and offers an alternative, namely that issuance of bad government debt played a key role in escalating a regular recession to an economic crisis
