I study the constrained efficient allocations of a simple model of risk sharing and capital flows across countries assuming that each country cannot commit to fully repay its contract obligations. In the model, the degree of risk sharing and the amount of investment are interdependent. It is...

Collective action clauses (CACs) are provisions specifying that a supermajority of bondholders can change the terms of a bond. We study how CACs determine governments' fiscal incentives, sovereign bond prices and default probabilities in environments with and without contingent debt and IMF...

The present paper shows that secondary markets can ameliorate, and sometimes fully solve, problems of sovereign risk in international financial markets. We study two environments. In the first one, private agents can in principle issue a complete set of state-contingent securities but...

Currencies that are at a forward premium tend to depreciate. This `forward premium-depreciation anomaly' represents an egregious deviation from uncovered interest parity. We document the returns to currency speculation strategies that exploit this anomaly. The first strategy, known as the carry...

This paper presents a fully rational general equilibrium model that produces a time-varying exchange rate risk premium and solves the uncovered interest rate parity (U.I.P) puzzle. In this two-country model, agents are characterized by slow-moving external habit preferences similar to Campbell &...

We focus on a quantitative assessment of rigid labor markets in an environment of stable monetary policy. We ask how wages and labor market shocks feed into the inflation process and derive monetary policy implications. We structurally model matching frictions and rigid wages in line with an...

I analyze how lack of commitment affects the maturity structure of sovereign debt. Ex post, the government trades off the gains from default induced redistribution against the cost of defaulting. Ex ante, the government issues debt of various maturities to raise an exogenous revenue requirement....

This paper combines default, settlement, and repayment history into a unified, dynamic borrowing model of sovereign debt. The model addresses two questions: 1) how the level of debt and the income profile affect the length of time a country in default is excluded from the international credit...
