During the booms that precede crises in emerging economies, policy makers often struggle to limit capital flows and their expansionary consequences. The main policy tool for this task is sterilization - essentially a swap of international reserves for public bonds. However, there is an extensive...

Emerging economies experience sudden stops in capital inflows. As we have argued in Caballero and Krishnamurthy (2002), having access to monetary policy during these sudden stops is useful, but mostly for insurance' rather than for aggregate demand reasons. In this environment, a central bank...

We study optimal monetary policy during temporary supply contractions when aggregate demand has inertia and expansionary policy is constrained. In this environment, it is optimal to run the economy hot until supply recovers. Positive output gaps in the low-supply phase lessen the negative output...

Countries have increased significantly their public-sector borrowing since the Global Financial Crisis. In this context, we document several potential fiscal dominance effects during 2000-2017 under Inflation Targeting (IT), and non-IT regimes. Higher ratios of public debt-to-GDP are associated...

This paper investigates the factors explaining exchange market pressures (EMP) and the hoarding and use of international reserves (IR) by emerging markets during the 2000s, as the Great Moderation turned to the 2008-9 global crisis and great recession. According to our results, both financial...

As a share of GDP, the U.S. Federal debt held by the public exceeds 50 percent in FY2009, the highest debt ratio since 1955. Projections indicate the debt ratio may be in the 70-100 percent range within ten years. In many respects, the temptation to inflate away some of this debt burden is...

Using a novel, high frequency dataset on capital control actions in 16 emerging market economies (EMEs) from 2001 to 2012, we provide new insights into the domestic and multilateral effects of capital controls. Increases in capital account openness reduce monetary policy autonomy and increase...

This paper investigates the potential impacts of the degree of divergence in open macroeconomic policies in the context of the trilemma hypothesis. Using an index that measures the relative policy divergence among the three trilemma policy choices, namely monetary independence, exchange rate...

This paper studies the optimal use of distortive policies aimed at raising a given real revenue, in a general equilibrium framework in which lump-sum taxes are absent. The policies analyzed are an inflation tax,commercial policy, and an implicit tax on capital inflows implemented by capital...

This paper investigates an economy in which there are short-term wage contracts that are re-negotiated under certain conditions. This paper determines the optimal frequency of wage re-negotiation and shows that it depends positively on measures of aggregate variability and Phillips curve slope....
