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...

We explore the parallels between Japanese currency policy after World War II and Chinese currency policy today. After two decades of pegging at 360 yen, Japan decoupled from the dollar on August 1971 and then repegged at a revalued rate of 308 yen. After stabilizing the exchange rate at this new...

Might the dollar eventually follow the precedent of the pound and cede its status as leading international reserve currency? Unlike ten years ago, there now exists a credible competitor: the euro. This paper econometrically estimates determinants of the shares of major currencies in the reserve...

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...

The paper reviews the recent literature on exchange rate target zones and on speculative attacks on fixed exchange rates. The influential Krugman model of exchange rate target zones has two main results, namely that credible target zones stabilize exchange rates more than fundamentals (the...

We study the curious patterns of gold holding and trading by central banks during 1979-2010. With the exception of several discrete step adjustments, central banks keep maintaining passive stocks of gold, independently of the patterns of the real price of gold. We also observe the...

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 study examines whether pre-crisis international reserve accumulations, as well as exchange rate and reserve policy decisions made during the global financial crisis, can help to explain cross-country differences in post-crisis economic performance. Our approach focuses not only on the total...

Foreign-exchange operations did not end after the United States stopped its activist approach to intervention. Japan persisted in such operations, but avoided overt conflict with its monetary policy. With the on-set of the Great Recession, Switzerland has transacted in foreign exchange both for...

Japanese official intervention in the foreign exchange market is of by far the largest magnitude in the world, despite little or no evidence that it is effective in moving exchange rates. This paper investigates the effectiveness of intervention using recently published Japanese official daily...
