We present a simple model of sovereign debt crises in which a country chooses its optimal mix of short and long-term debt contracts subject to standard contracting frictions: the country cannot commit to repay its debts nor to a specific path of future debt issues, and contracts cannot be made...

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...

This paper provides a selective survey of the incidence, causes, and consequences of a country’s choice of its exchange rate regime. I begin with a critical review of Klein and Shambaugh’s (2010) book Exchange Rate Regimes in the Modern Era, and then proceed to provide an alternative...

This paper provides evidence of heterogeneous treatment effects on trade from switching among three types of de-facto exchange rate regimes: freely floating, currency bands, and pegs or currency unions. A cottage literature at the interface of macroeconomics and international economics focuses...

This paper assesses whether the international monetary system is already tri-polar and centred around the US dollar, the euro and the Chinese renminbi (RMB). It focuses on what we call China’s" dominance hypothesis", i.e. whether the renminbi is already the dominant currency in Asia, exerting...

While the global financial crisis was centered in the United States, it led to a surprising appreciation in the dollar, suggesting global dollar illiquidity. In response, the Federal Reserve partnered with other central banks to inject dollars into the international financial system. Empirical...

This paper studies the geography of wealth transfers during the 2008 global financial crisis. We construct valuation changes on bilateral external positions in equity, direct investment and portfolio debt at the height of the crisis to map who benefited and who lost on their external exposure....

We use a standard metric from international finance, the currency risk premium, to assess the credibility of fixed exchange rates during the classical gold standard era. Theory suggests that a completely credible and permanent commitment to join the gold standard would have zero currency risk or...

This paper studies fiscal policy in a model of sovereign debt and default. A time-inconsistency problem arises: since the price of past debt cannot be affected by current fiscal policy and governments cannot credibly commit to a certain path of tax rates, debtor countries choose suboptimally low...
