This paper develops a dynamic two-country neoclassical stochastic growth model with incomplete markets. Short-term credit flows can be excessive and reverse suddenly. The equilibrium outcome is constrained inefficient due to pecuniary externalities. First, an undercapitalized country borrows too...

We explore the impact of mortgage securitization on the international diversification of macroeconomic risk. By making mortgage-related risks internationally tradeable, securitization contributes considerably to better international consumption risk sharing: we find that countries with the most...

We analyse how reversals of several types of capital flows impact currency crises in emerging market and developing economies. Estimates of logit models show that reversals of (equity and debt) portfolio flows significantly increase the likelihood of currency crises in emerging market economies....

I analyze the optimal design of banking supervision in the presence of cross-border lending. Cross-border lending could imply that an individual bank failure in one country could trigger negative spillover effects in another country. Such cross-border contagion effects could turn out to be...

This paper explains both the onset of the financial crisis in 1998 and the striking economic recovery afterwards in Russia and other Former Soviet Union (FSU) economies. Before the crisis banks do not lend to the real sector of the economy and firms use non-bank finance, including trade credits...

The severity and depth of the recent financial crisis hit many by surprise. Despite warning signs, the financial system seems to have been unable to aggregate existing information. As the events of Fall 2008 showed, many investors were caught off guard by the large number of banks collapsing...

Interbank claims are a concern to regulators as they might facilitate the dissemination of defaults and generate spill-over effects. Building on a simple model, this paper introduces a measure of the spill-over effects that a bank generates when it defaults. The measure is based on an explicit...

The paper analyzes a very stylized model of crises and demonstrates how the degree of strategic complementarity in the actions of investors is a critical determinant of fragility. It is shown how the balance sheet composition of a financial intermediary, parameters of the information structure...

We build a tractable stylized model of external sovereign debt and endogenous international interest rates. In corrupt economies with rent-seeking groups stealing public resources, a politico-economic equilibrium is characterized by permanent fiscal impatience which leads to excessive issuing of...

We develop a simple model of banking regulation with two policy instruments: minimum capital requirements and supervision of domestic banks. The regulator faces a trade-off: high capital requirements cause a drop in the banks'; profitability, while strict supervision reduces the scope of...
