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 provide a theory of the determination of exchange rates based on capital flows in imperfect financial markets. Capital flows drive exchange rates by altering the balance sheets of financiers that bear the risks resulting from international imbalances in the demand for financial assets. Such...

In 2007, countries in the euro periphery were enjoying stable growth, low deficits, and low spreads. Then the financial crisis erupted and pushed them into deep recessions, raising their deficits and debt levels. By 2010, they were facing severe debt problems. Spreads increased and,...

We examine the first widespread use of capital controls in response to a global or regional financial crisis. In particular, we analyze whether capital controls mitigated capital flight in the 1930s and assess their causal effects on macroeconomic recovery from the Great Depression. We find...

In this paper, we present data on trends over time in government debt financing in Japan since 2010 with emphasis on the importance of foreign holders and speculate about the determinants of those trends. We find that Japanese government securities were held primarily by domestic holders until...

Emerging markets do not handle adverse shocks well. In this paper, I will outline an explanation of why emerging markets are so fragile, and why they may adopt contractual mechanisms -- such as a dollarized banking system -- that increase their fragility. I draw on this analysis to explain why...

We analyze the Brazilian experience in the 1990s to assess the effectiveness of controls on capital inflows in restricting financial inflows and changing their composition towards long term flows. Econometric exercises (VARs) showed that controls on capital inflows were effective in deterring...

The onset of the US credit crisis in 2008, and its rapid globalization induced the FED to extend unprecedented swap-lines of 30 billion dollars to four emerging markets, and the proliferation of other cross-countries selective swap arrangements. This paper explores the logic for these...

We extend the sudden stops literature by allowing crisis episodes to be caused by either the retreat of global investors, as is assumed but not shown in the extant literature, or the sudden flight of local investors. We find that almost half of the previously defined sudden stops are actually...

Ongoing international financial integration has greatly increased foreign asset holdings across countries, enhancing the scope for a "valuation channel" of external adjustment (i.e., the changes in a country's net foreign asset position due to exchange rate and asset price changes). We examine...
