We analyze the policy trade-offs generated by local currency price stability of imports in economies where upstream producers strategically interact with downstream firms selling the final goods to consumers. We study the effects of staggered price setting at the downstream level on the optimal...

In this paper we connect the events of the last twelve months, "The Panic of 2008" as it has been called, to the demand for international reserves. In previous work, we have shown that international reserve demand can be rationalized by a central bank's desire to backstop the broad money supply...

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...

The global economy has a chronic shortage of safe assets which lies behind many recent macroeconomic imbalances. This paper provides a simple model of the Safe Asset Mechanism (SAM), its recessionary safety traps, and its policy antidotes. Safety traps share many common features with...

The valuation of government debt is subject to strategic uncertainty, stemming from investors' sentiments. Pessimistic lenders, fearing default, bid down the price of debt. This leaves a government with a higher debt burden, increasing the likelihood of default and thus confirming the pessimism...

The optimal currency area (OCA) concept is central to the economic analysis of monetary unions, as it clearly identifies the relevant optimizing tradeoff: extension of the area over which a single currency is used enhances allocative efficiency but reduces the possibility of tailoring monetary...

Formation of the Euro area raises new questions about the coordination of monetary and fiscal policy. Using a New Neoclassical Synthesis (NNS) model, we show that a common monetary policy, responding to area-wide aggregates, has asymmetric effects on countries within the union, depending on...

This paper studies the role of exit from a monetary union during a debt crisis. A monetary union, such as the European Monetary Union, needs to establish a procedure for exit as a tool to cope with debt default. The paper studies various forms of exit and argues that "Euroization" is both a...

We lay down a standard macroeconomic model of a small open economy with a fixed exchange rate and study optimal capital controls (defined as maximizing the utility of a representative household). We provide sharp analytical and numerical characterizations for a variety of shocks. We find that...

The paper explicates the issues raised for macroprudential regulation in a global economy with high capital mobility. The study surveys the recent literature and aims to translate the academic rationale for such policies, in which market imperfections lead to external effects that require policy...
