Fluctuations in the aggregate balance sheets of financial intermediaries provide a window on the joint determination of asset prices and macroeconomic aggregates. We document that financial intermediary balance sheets contain strong predictive power for future excess returns on a broad set of...

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...

The VIX, the stock market option-based implied volatility, strongly co-moves with measures of the monetary policy stance. When decomposing the VIX into two components, a proxy for risk aversion and expected stock market volatility (“uncertainty”), we find that a lax monetary policy decreases...

We study the effects of technological change on financial intermediation, distinguishing between innovations in information (data collection and processing) and communication (relationships and distribution). Both follow historic trends towards an increased use of hard information and less...

This essay reflects upon the relationship between the current theory of financial intermediation and real-world practice. Our critical analysis of this theory leads to several building blocks of a new theory of financial intermediation. Current financial intermediation theory builds on the...

In a market-based financial system, banking and capital market developments are inseparable. We document evidence that balance sheets of market-based financial intermediaries provide a window on the transmission of monetary policy through capital market conditions. Short-term interest rates are...

The financial crisis of 2007-09 has sparked keen interest in models of financial frictions and their impact on macro activity. Most models share the feature that borrowers suffer a contraction in the quantity of credit. However, the evidence suggests that although bank lending contracted during...

The rapid growth of the market-based financial system since the mid-1980s changed the nature of financial intermediation in the United States profoundly. Within the market-based financial system, 'shadow banks' are particularly important institutions. Shadow banks are financial intermediaries...

Shocks in the financial sector caused the great recession of 2008 and pulled down the real economy. To implement financial dynamics in a stylized DSGE-framework we use behavioral elements in expectations to produce waves of bull and bear cycles in the financial intermediation process, that have...
