We study the dynamics linking monetary policy with bank leverage and show that adjustments in leverage act as the linchpin in the monetary transmission mechanism that works through fluctuations in risk-taking. Motivated by the evidence, we formulate a model of the "risk-taking channel" of...

We investigate global factors associated with cross-border capital flows. We formulate a model of gross capital flows through the international banking system and derive a closed form solution that highlights the leverage cycle of global banks as being a prime determinant of the transmission of...

This paper develops methods for assessing the sensitivity of capital flows to global financial conditions, and applies the methods in assessing the impact of macroprudential policies introduced by Korea in 2010. Relative to a comparison group of countries, we find that the sensitivity of capital...

A lending boom is reflected in the composition of bank liabilities when traditional retail deposits (core liabilities) cannot keep pace with asset growth and banks turn to other funding sources (non-core liabilities) to finance their lending. We formulate a model of credit supply as the flip...

The headline numbers appear to show that even as banks and financial intermediaries suffered large credit losses in the financial crisis of 2007-09, they raised substantial amounts of new capital, both from private investors and through government-funded capital injections. However, on closer...

In spite of mounting losses banks continued to pay dividends during the crisis. We present a model that addresses this behavior. By paying out dividends, a bank transfers value to its shareholders away from creditors, among whom are other banks. This way, one bank's dividend payout policy...

The availability of credit varies over the business cycle through shifts in the leverage of financial intermediaries. Empirically, we find that intermediary leverage is negatively aligned with the banks' Value-at-Risk (VaR). Motivated by the evidence, we explore a contracting model that captures...

The financial crisis of 2007-9 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 to firms declines...

What is the effect of financial crises and their resolution on banks' choice of liquid asset holdings? When risky assets have limited pledgeability and banks have relative expertise in employing risky assets, the market for these assets clears only at fire-sale prices following a large number of...
