Using the "trilemma indexes" developed by Aizenman et al. (2008) that measure the extent of achievement in each of the three policy goals in the trilemma--monetary independence, exchange rate stability, and financial openness--we examine how policy configurations affect macroeconomic...

We develop a methodology that intuitively characterizes the choices countries have made with respect to the trilemma during the post Bretton-Woods period. The paper first outlines the new metrics for measuring the degree of exchange rate flexibility, monetary independence, and capital account...

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...

The rapid growth of international reserves---a development concentrated in the emerging markets---remains a puzzle. In this paper we suggest that a model based on financial stability and financial openness goes far toward explaining reserve holdings in the modern era of globalized capital...

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...

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...

Gross stocks of foreign assets have increased rapidly relative to national outputs since 1990, and the short-run capital gains and losses on those assets can amount to significant fractions of GDP. These fluctuations in asset values render the national income and product account measure of the...

We show that the when one takes into account the global equilibrium ramifications of an unwinding of the US current account deficit, currently estimated at 5.4% of GDP, the potential collapse of the dollar becomes considerably larger--more than 50% larger--than our previous estimates (Obstfeld...

This paper is structured in three parts. The first part outlines the methodological steps, involving both theoretical and empirical work, for assessing whether an observed allocation of resources across countries is efficient. The second part applies the methodology to the long-run allocation of...

We provide an overview of the recent developments of the literature on the determinants of long term capital flows, global imbalances and valuation effects. We present the main stylized facts of the new international financial landscape in which external balance sheets of countries have grown in...
