A flexible instrument to insure against adverse exchange rate movements are options on foreign currency. Often a relatively simple foreign currency option valuation model is used to address issues related to the pricing and hedging of such options. The results of many empirical studies document that real-world foreign currency option premia deviate from those predicted by the baseline model. In the first part of the book, it is shown that a noise trader model can help to explain the observed mispricing of the baseline foreign currency option pricing model. In the second part of the book, it is studied how policymakers can exploit the pricing errors of the baseline model. In particular, it is examined how option pricing theory can be applied to assess the effectiveness of central bank interventions in the foreign exchange market. To this end, a model is constructed to analyze the effectiveness of the interventions conducted by the Deutsche Bundesbank during the Louvre period.

Since the September 1985 Plaza Hotel announcement by the Group of Five industrial countries, a substantial realignment of exchange rates has been achieved. At the same time, foreign exchange market intervention, much of it concerted and much of it sterilized, has been undertaken on a scale not seen since the early 1970s This paper takes a fresh look at the effectiveness of sterilized intervention in the light of recent experience. The paper concludes that sterilized intervention, in itself, has played an unimportant role in promoting exchange-rate realignment. Instead, clear shifts in patterns of monetary and fiscal policy appear to have been the main medium-term policy factors determining currency values. Over certain shorter time periods, intervention has influenced exchange markets through a signalling channel; but this signalling effect has been operative only as a result of authorities' frequent readiness to adjust monetary policies promptly to counteract unwelcome exchange-market pressures. The paper makes some progress in formalizing reasons why intervention might enhance the credibility of messages that governments could convey as well through simple verbal announcements.

This book explains why central banks continue to carry out foreign exchange interventions despite their poor track record. It uses confidential daily intervention data from the Bundesbank and the Federal Reserve.

Transatlantic economic relations are dominated by three factors which are of major historical significance. The first and most important is the multilateral process for trade liberalisation, deregulation of financial markets, and macroeconomic policy co-ordination. The second factor is a transatlantic environment of national and regional idiosyncrasies exemplified by protectionist initiatives, a significant weakening of the EMS, and changes in central bank statutes. The second factor is in part a political backlash against the first. The third factor affecting transatlantic economic relations is of course the emergence of regional economic relationships within the transatlantic economy, and a treaty calling for a common currency in Europe. In this 1996 volume, specialists in international trade, international finance, and political economy analyse the causes of these three factors, and their implications.

The contributions are concerned with the theoretical and empirical analyses of fixed and flexible exchange rate systems, the role of central bank and other government policies in such systems, the prospects, workings and effects of a European Monetary System, and capital mobility and economic integration.
