This paper addresses the issue of the optimal stock of international reserves in terms of a statistical model in which reserves affect both the probability of a Sudden Stop-as well as associated output costs-by reducing the balance-sheet effects of liability dollarization. Optimal reserves are...

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...

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...

Fiat money contains the seeds of its own destruction. It has no intrinsic value and, yet, it can be exchanged for valuable consumption and production goods. As Hahn (1965) shows, this situation puts fiat money's market value or liquidity premium at the brink of collapse. In this paper I will...

Fluctuations in commodity prices are often associated with macroeconomic volatility. But not all nations are created equal in this regard. The macro response to commodity booms and busts depends both on the structural characteristics of the economy and on the policy framework that is in place....

We develop a flexible semiparametric time series estimator that is then used to assess the causal effect of monetary policy interventions on macroeconomic aggregates. Our estimator captures the average causal response to discrete policy interventions in a macro-dynamic setting, without the need...

This paper seeks to understand the interplay between banks, bank regulation, sovereign default risk and central bank guarantees in a monetary union. I assume that banks can use sovereign bonds for repurchase agreements with a common central bank, and that their sovereign partially backs up any...

From 2000 to 2003, when Ben Bernanke was a professor and then a Fed Governor, he wrote extensively about monetary policy at the zero bound on interest rates. He advocated aggressive stimulus policies, such as a money-financed tax cut and an inflation target of 3-4%. Yet, since U.S. interest...

This paper seeks to understand the behavior of Greenspan's Federal Reserve in the late 1990s. Some authors suggest that the Fed followed a simple 'Taylor rule,' while others argue that it deviated from such a rule because it recognized that the 'New Economy' permitted an easing of policy. We...
