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...

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...

To study the joint decision of holding sovereign debt and reserves, we construct a stochastic dynamic equilibrium model that incorporates willingness-to-pay incentive problems. In this setup, debt and assets are not perfect substitutes, as reserves can be used even after a country has defaulted....

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...

This paper addresses the issue of the optimal stock of international reserves in terms of a statistical model in which reserves affect both the probability of a Sudden Stop-as well as associated output costs-by reducing the balance-sheet effects of liability dollarization. Optimal reserves are...

This study examines whether pre-crisis international reserve accumulations, as well as exchange rate and reserve policy decisions made during the global financial crisis, can help to explain cross-country differences in post-crisis economic performance. Our approach focuses not only on the total...

The 'International Policy Trilemma' refers to the constraint on independent monetary policy that is forced on a country which remains open to international financial markets and simultaneously pursues an exchange rate target. This paper shows that, in a global economy with open financial...
