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.

Globalization deeply affects economic structures and raises the issue of how governments should respond to new challenges. In this book, various ways of improving the institutional setup for global governance are discussed by renowned experts.

The advantages of free international trade as well as the fears of those who are against globalization are considered in the contributions.

This paper considers the central bank mandate with respect to financial stability and identifies the links to the functioning of securities markets. It argues that while emergency support to securities markets is an important part of the crisis management response, a high bar should be set for its use. Importantly, it should be used only as part of a comprehensive policy package. The paper considers what types of securities markets may be important for financial stability, what market conditions could trigger emergency support measures, and how programs can be designed to restore market functioning while minimizing moral hazard.

Explaining the puzzling behavior of exchange rates using models from microstructure finance and data from electronic trading.

Not long ago, secrecy was the byword in central banking circles, but now the unmistakable trend is towards greater openness and transparency. This, the third Geneva Report on the World Economy, describes and evaluates some of the changes in how central banks talk to the markets, to the press, and to the public. The report first assesses the case for transparency ? defined as providing sufficient information for the public to understand the policy regime ? and concludes that it is very strong, based on both policy effectiveness and democratic accountability. It then examines what should be the content of communication and argues that central banks ought to spell out their long-run objectives and methods. It then investigates the link between the decision-making process and central bank communication, drawing a distinction between individualistic and collegial committees. The report concludes with a review of the communications strategies of some of the main central banks.

The foreign exchange market is the largest, fastest-growing financial market in the world. Yet conventional macroeconomic approaches do not explain why people trade foreign exchange. At the same time, they fail to explain the short-run determinants of the exchange rate. These nine innovative essays use a microstructure approach to analyze the workings of the foreign exchange market, with special emphasis on institutional aspects and the actual behavior of market participants. They examine the volume of transactions, heterogeneity of traders, the time of day and location of trading, the bid-ask spread, and the high level of exchange rate volatility that has puzzled many observers. They also consider the structure of the market, including such issues as nontransparency, asymmetric information, liquidity trading, the use of automated brokers, the relationship between spot and derivative markets, and the importance of systemic risk in the market. This timely volume will be essential reading for anyone interested in the economics of international finance.
