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...

We study the effects of credit shocks in a model with heterogeneous entrepreneurs, financing constraints, and a realistic firm-size distribution. As entrepreneurial firms can grow only slowly and rely heavily on retained earnings to expand the size of their business, we show that, by reducing...

The provision of credit has been shown to be eminent for macroeconomic activity.Recent research highlighted that optimism may play a role in the provision of credit through leverage cycles. A decomposition of corporate bond spreads allows the modelling of a propensity-to-lend through an excess...

We present a DSGE model where firms optimally choose among alternative instruments of external finance. The model is used to explain the evolving composition of corporate debt during the financial crisis of 2008-09, namely the observed shift from bank finance to bond finance, at a time when the...

This paper constructs a two-country DSGE model to study the nature of the recent financial crisis and its effects that spread immediately throughout the world owing to the globalization of banking. In the model, financial intermediaries (FIs) enter into chained credit contracts at home and...

This paper analyzes, from a theoretical perspective, the role of the financial system to promote growth and macroeconomic stability. It also endogenously explains the performance of the financial systems as a consequence of industrial (or sectoral) diversification. In the model, the productive...

Many economists believe that the stock market plays an important role in efficiently allocating capital to its most productive uses. This standard story of the stock market was called into question by events in the late 1990s, when some observers believed that stock market overvaluation – or a...

Various papers have identified shocks to investment as major drivers of output, investment, hours, and interest rates. These investment shocks have been linked to financial frictions because financial markets are instrumental in transforming consumption goods into installed capital. However, the...

We explore shocks to expected future productivity in a model with limited enforcement of financial contracts. A microfounded collateral constraint implies that good news about future productivity yield an increase in stock prices, available credit and a general economic expansion.
