A long-standing puzzle in international finance is the durability of the dollar's share of foreign exchange reserves - which remains above 60%, while the weight of the US economy in global output has fallen to less than a quarter. We argue that the dollar's role may reflect instead the share of...

This paper presents a new concept - the global roles of currencies. The concept combines the domestic and international (cross-border) use of currencies and therefore captures the overall importance of different currencies in a globalised economy. The measure of a currency's global role is based...

While virtually all modern currency crisis models recognise that the decision to abandon an exchange rate peg depends on how tenaciously policy makers are willing to defend it, they seldom model how this is done. We incorporate both the mechanics of speculation and of a defence policy against...

While virtually all currency crisismodels recognise that the fate of a currency peg depends on how tenaciously policy makers defend it, they seldom model how this is done. We incorporate themechanics of speculation and the interest rate defence against it in the model ofMorris and Shin (American...

While virtually all modern models of exchange rate crises recognise that the decision to abandon an exchange rate peg depends on how harshly policy makers are willing to defend the regime, they virtually never model how the exchange rate is defended. In this paper we incorporate both the...

We analytically derive optimal central bank portfolios in a minimum variance framework with two assets and quot;transaction demandsquot; caused by sudden stops in capital inflows. In this model, the transaction demands become less important relative to traditional portfolio objectives as debt to...

The need for US dollar funding during the financial stresses in mid-March 2020, as the COVID pandemic news shocked markets, was evident in a number of countries. Notably, however, China’s dollar liquidity needs received little attention. Given China’s deepening economic and financial...

The structural VAR models for European countries (France, Denmark, and Germany) are developed to examine the monetary policy reactions, especially the within-ERM exchange rate stabilization, during the ERM period. First, impulse responses of monetary instrument and the exchange rate to shocks...

The idea of inflation targeting in emerging countries is not a new one. There have been papers that favor or reject the idea of implementing such a system in these countries for mainly institutional reasons. This paper does not deal with these normative arguments. Emerging countries are...
