Exchange Rate Theory


Book Description

"Exchange Rate Theory presents a novel and elegant theory to explain the excessive variability of foreign exchange rate returns. The theory is novel in the sense that it focuses on interaction between market agents as the primary source of the variability in those speculative prices. It is shown that simple interactions between market participants using different information is sufficient to generate deterministic chaos." "In the first part of this book the authors survey existing exchange rate theories and ask whether these theories are useful in explaining actual exchange rate movements. They demonstrate that the 1970s were characterized by the belief that exchange rates could be understood by an analysis of the fundamentals (inflation rates, interest rates and monetary policy). Subsequently, this belief has all but disappeared but researchers have been content to analyze the statistical properties of exchange rates, abandoning the theory and the models." "The second part of the book uses chaos theory to construct an innovative framework for the understanding of exchange markets. These models, which integrate fundamentalism and chartism, create complex exchange rate movements which appear to be random. These models are used to explain several of the anomalies observed in exchange rate markets and to evaluate the possibility of exchange rate prediction."--BOOK JACKET.Title Summary field provided by Blackwell North America, Inc.

The Exchange Rate in a Behavioral Finance Framework


Book Description

This book provides an alternative view of the workings of foreign exchange markets. The authors' modeling approach is based on the idea that agents use simple forecasting rules and switch to those rules that have been shown to be the most profitable in the past. This selection mechanism is based on trial and error and is probably the best possible strategy in an uncertain world, the authors contend. It creates a rich dynamic in the foreign exchange markets and can generate bubbles and crashes. Sensitivity to initial conditions is a pervasive force in De Grauwe and Grimaldi's model. It explains why large exchange-rate changes and volatility clustering occur. It also has important implications for understanding how the news affects the exchange rate. De Grauwe and Grimaldi conclude that news in fundamentals has an unpredictable effect on the exchange rate. Sometimes, they maintain, it alters the exchange rate considerably; at other times it has no effectwhatsoever. The authors also use their model to analyze the effects of official interventions in the foreign exchange market. They show that simple intervention rules of the "leaning-against-the-wind" variety can be effective in eliminating bubbles and crashes in the exchange rate. They further demonstrate how, quite paradoxically, by intervening in the foreign exchange market the central bank makes the market look more efficient. Clear and comprehensive, The Exchange Rate in a Behavioral Finance Framework is a must-have for analysts in foreign exchange markets as well as students of international finance and economics.

Handbook of Exchange Rates


Book Description

Praise for Handbook of Exchange Rates “This book is remarkable. I expect it to become the anchor reference for people working in the foreign exchange field.” —Richard K. Lyons, Dean and Professor of Finance, Haas School of Business, University of California Berkeley “It is quite easily the most wide ranging treaty of expertise on the forex market I have ever come across. I will be keeping a copy close to my fingertips.” —Jim O’Neill, Chairman, Goldman Sachs Asset Management How should we evaluate the forecasting power of models? What are appropriate loss functions for major market participants? Is the exchange rate the only means of adjustment? Handbook of Exchange Rates answers these questions and many more, equipping readers with the relevant concepts and policies for working in today’s international economic climate. Featuring contributions written by leading specialists from the global financial arena, this handbook provides a collection of original ideas on foreign exchange (FX) rates in four succinct sections: • Overview introduces the history of the FX market and exchange rate regimes, discussing key instruments in the trading environment as well as macro and micro approaches to FX determination. • Exchange Rate Models and Methods focuses on forecasting exchange rates, featuring methodological contributions on the statistical methods for evaluating forecast performance, parity relationships, fair value models, and flow–based models. • FX Markets and Products outlines active currency management, currency hedging, hedge accounting; high frequency and algorithmic trading in FX; and FX strategy-based products. • FX Markets and Policy explores the current policies in place in global markets and presents a framework for analyzing financial crises. Throughout the book, topics are explored in-depth alongside their founding principles. Each chapter uses real-world examples from the financial industry and concludes with a summary that outlines key points and concepts. Handbook of Exchange Rates is an essential reference for fund managers and investors as well as practitioners and researchers working in finance, banking, business, and econometrics. The book also serves as a valuable supplement for courses on economics, business, and international finance at the upper-undergraduate and graduate levels.




Nonlinearity, Bounded Rationality, and Heterogeneity


Book Description

This book pursues a nonlinear approach in considering both chaotic dynamical models and agent-based simulation models of economics, as well as their dynamical behaviors. Three key concepts arising in this context are “nonlinearity,” “bounded rationality” and “heterogeneity,” which also make up the title of the book. Nonlinearity is the warp that runs throughout all models because systems that exhibit chaotic or other complex behavior in the absence of any exogenous disturbances are absolutely nonlinear. Bounded rationality constitutes the woof, because economic systems do not exhibit complex behavior if all agents are perfectly rational, as is usually assumed in neoclassical economics. Agents who are boundedly rational have to struggle to do their best with limited information and tend to adapt to their economic environment without knowing what is the best. Furthermore, the heterogeneity of firms or consumers dyes the fabric of complex dynamics woven from the warp and woof.




Money and the Economy


Book Description

This book provides a comprehensive and systematic introduction to the problem of the definition of money and investigates the gains that can be achieved by a rigorous use of microeconomic- and aggregation-theoretic foundations in the construction of monetary aggregates. It provides readers with key aspects of monetary economics and macroeconomics, including monetary aggregation, demand systems, flexible functional forms, long-run monetary neutrality, the welfare cost of inflation, and nonlinear chaotic dynamics.This book offers the following conclusions: the simple-sum approach to monetary aggregation and log-linear money demand functions, currently used by central banks, are inappropriate for monetary policy purposes; the choice of monetary aggregation procedure is crucial in evaluating the welfare cost of inflation; the inter-related problems of monetary aggregation and money demand will be successfully investigated in the context of flexible functional forms that satisfy theoretical regularity globally, pointing the way forward to useful and productive research.




Macroeconomic Linkage


Book Description

This volume explores East Asia's macroeconomic experience in the 1980s and the economic impact of East Asia's growth on the rest of the world. The authors explore the causes of capital flows, changes in trade balances, and exchange rate fluctuations in East Asia and their effects on other countries. These fourteen papers are organized around four themes: the overall determinants of growth and trading relations in the East Asian region; monetary policies in relation to capital controls and capital accounts; the impact of exchange rate behavior on industrial structure; and the potential for greater regional integration. The contributors examine interactions among exchange rate movements, trade balances, and capital flows; how government monetary policy affects capital flows; the effect of exchange rates on industrial structure, inventories, and prices; and the extent of regional integration in East Asia.




On the credibility issue of exchange rate target zones


Book Description

Inhaltsangabe:Zusammenfassung: Währungskrisen, wie die des Europäischen Währungssystems (EWS) 1992, können noch immer nur unzureichend vorausgesagt werden. Es wird jedoch anerkannt, dass die Glaubwürdigkeit eines jeden Währungssystems ausschließlich endogen bestimmt wird, d.h. durch Interaktion der einzelnen Akteure an den Wechselkursmärkten. Die vorliegende Arbeit untersucht, ob ein bestimmtes Glaubwürdigkeitsmaß, eingeführt von Avesani, Gallo und Salmon (1995), geeignet ist, die große EWS Krise 1992 vorauszusagen. Dabei handelt es sich um ein dynamisches Spiel, in dem die beiden Akteure (Zentralbank und Finanzmarkt) miteinander interagieren und damit die Glaubwürdigkeit des Systems aushandeln . Es wird gezeigt, dass o.g. Glaubwürdigkeitsmaß ein geeigneter Indikator für Währungskrisen darstellt, was empirisch anhand des französischen Francs, der italienischen Lira und des niederländischen Guldens nachgewiesen wird. Introduction: The objective of the present study is to present the literature of exchange rate target zones and to explore empirically the Avesani-Gallo-Salmon credibility measure for selected currencies belonging to the Exchange-Rate Mechanism (ERM) of the European Monetary System (EMS). In the past decade the empirical literature on real world target zones mushroomed considerably, but still, its overall significance in explaining strains in the relevant foreign exchange markets remains relatively low. In this context, I will explore whether the Avesani-Gallo-Salmon (1995) credibility measure demonstrates more power than earlier studies in the analysis of the 1992/3 EMS crisis. It is not my intention to pursue a normative analysis whether flexible or fixed exchange rates or intermediate regimes are superior to one another in terms of their economic implications. This question is beyond the scope of my analysis.1 Given that target zones are applied frequently in the real world, I purely want to figure out, whether their application is sensible on grounds of a firm commitment of the policy-makers. Exchange rate bands have been discussed widely after the breakdown of the Bretton Woods System in 1973. Although experiences with the fixed exchange rate regime were disappointing in the 1960s, increased volatility and/or overshooting of the exchange rates in the 1970s let economists doubt the famous argument by Friedman (1953) that speculation would stabilize exchange rate movements in the floating system. McKinnon (1976) reckoned that [...]




Handbook of International Economics


Book Description

This reference accords recognition to the recent revolution in macroeconomics wrought by imperfect competition. Grossman and Rogoff (Princeton U.) present chapters by two dozen contributors on two prime areas of research interest: international trade theory and policy (e.g. strategic trade patterns and policies, the relationship between trade and technological progress), and open economy macroeconomics and international finance (covering such topics as exchange rates, foreign lending, and policy coordination). The volume commences with Krugman's overview of the positive theory of international trade, and concludes with analyses of sovereign debt. Annotation copyrighted by Book News, Inc., Portland, OR.
