Exchange rate economics is an important field of investigation for academics, professionals and policy-makers. This book provides a comprehensive survey of the theory of and empirical evidence on the determination and effects of exchange rates. The exposition utilizes both diagrammatic and mathematical representations of the underlying models. The book is a comprehensive reference for those engaged in this field of research.
This book presents an extensive survey of the theory and empirics of international parity conditions which are critical to our understanding of the linkages between world markets and the movement of interest and exchange rates across countries. The book falls into three parts dealing with the theory, methods of econometric testing and existing empirical evidence. Although it is intended to provide a consensus view on the subject, the authors also make some controversial propositions, particularly on the purchasing power parity conditions.
"The process by which securities are traded is very different from the idealized picture of a frictionless and self-equilibrating market offered by the typical finance textbook. This book offers a more accurate and authoritative take on this process. The book starts from the assumption that not everyone is present at all times simultaneously on the market, and that participants have quite diverse information about the security's fundamentals. As a result, the order flow is a complex mix of information and noise, and a consensus price only emerges gradually over time as the trading process evolves and the participants interpret the actions of other traders. Thus, a security's actual transaction price may deviate from its fundamental value, as it would be assessed by a fully informed set of investors. The book takes these deviations seriously, and explains why and how they emerge in the trading process and are eventually eliminated. The authors draw on a vast body of theoretical insights and empirical findings on security price formation that have come to form a well-defined field within financial economics known as "market microstructure." Focusing on liquidity and price discovery, the book analyzes the tension between the two, pointing out that when price-relevant information reaches the market through trading pressure rather than through a public announcement, liquidity may suffer. It also confronts many striking phenomena in securities markets and uses the analytical tools and empirical methods of market microstructure to understand them. These include issues such as why liquidity changes over time and differs across securities, why large trades move prices up or down, and why these price changes are subsequently reversed, and why we observe temporary deviations from asset fair values"--
A stable money demand forms the cornerstone in formulating and conducting monetary policy. Consequently, numerous theoretical and empirical studies have been conducted in both industrial and developing countries to evaluate the determinants and the stability of the money demand function. This paper briefly reviews the theoretical work, tracing the contributions of several researchers beginning from the classical economists, and explains relevant empirical issues in modeling and estimating money demand functions. Notably, it summarizes the salient features of a number of recent studies that applied cointegration/error-correction models in the 1990s, and it features a bibliography to aid in research on demand for money.
Experts have long questioned the effect of currency undervaluation on overall GDP growth. They have viewed the underlying basis for this policy--intervention in currency markets to keep the price of the home currency cheap--as doomed to failure on both theoretical and empirical grounds. Moreover, the view has been that overvalued currencies hurt economic growth but undervalued currencies cannot help in growth acceleration. A parallel belief has been that the real exchange rate--that is, a country's competitive ranking--cannot be affected by merely changing the nominal exchange rate. This view is grounded in the belief, and expectation, that inflation follows any devaluation of currency. Hence, the conclusion that the real exchange rate cannot be affected by policy. However, given China's remarkable performance in recent decades, this traditional view is being reexamined. China devalued its currency by large amounts in the 1980s and early 1990s; instead of inflation, it achieved high growth. Today, there is near-universal demand for China to significantly revalue its currency. This book examines the veracity of various propositions relating to currency misalignments, and their effect on various items of policy interest. The author subjects more than a century of global exchange rate management and growth outcomes to rigorous empirical analysis and demonstrates convincingly that a country can systematically devalue and yet prosper. The analysis helps in interpreting several phenomena, especially for the last three decades, which have witnessed high economic growth in developing countries, a widening of global imbalances, and a sharp increase in reserve accumulation, particularly among high-growth Asian economies. The book shows that these events are strongly linked via a consistent policy of currency undervaluation in Asian economies.
This paper presents a rule for foreign exchange interventions (FXI), designed to preserve financial stability in floating exchange rate arrangements. The FXI rule addresses a market failure: the absence of hedging solution for tail exchange rate risk in the market (i.e. high volatility). Market impairment or overshoot of exchange rate between two equilibria could generate high volatility and threaten financial stability due to unhedged exposure to exchange rate risk in the economy. The rule uses the concept of Value at Risk (VaR) to define FXI triggers. While it provides to the market a hedge against tail risk, the rule allows the exchange rate to smoothly adjust to new equilibria. In addition, the rule is budget neutral over the medium term, encourages a prudent risk management in the market, and is more resilient to speculative attacks than other rules, such as fixed-volatility rules. The empirical methodology is backtested on Banco Mexico’s FXIs data between 2008 and 2016.
This book collects my scholarly research on the behavior of foreign exchange rates conducted over the past twenty-five years. The collection includes papers that study the behavior of exchange rates from the traditional macroeconomic and newer microstructure perspectives. The former perspective considers the linkages between the macro economy and currency prices in an effort to understand the behavior of exchange rates over quarters, years and decades. By contrast, the microstructure perspective considers how the details of currency trading affect how macroeconomic information becomes embedded in currency prices, a process which drives exchange-rates over intraday horizons. The book also contains papers with a hybrid perspective that consider the details of currency trading and macroeconomic linkages in an effort to understand exchange-rate dynamics across all horizons.
The contributors to this volume analyze the growth experiences of Japan, Korea, China, Hong Kong, Singapore, and Taiwan in light of the recently developed endogenous growth theory to provide an understanding of the economic boom in East Asia. The theory explored in this volume attributes the phenomenal economic success of these countries to, among other factors, the role of an outward orientation—a focus on exporting rather than on protecting home markets. In addition, the importance of exchange rate behavior, of the supportive role of government policy, and of the accumulation and promotion of physical and human capital are explored in detail. This collection also examines the extent to which growth in each country became self-sustaining once it began. Demonstrating the relevance of endogenous growth theory for studying this important region, this fourth volume in the NBER-East Asia Seminar on Economics series will be of interest to observers of East Asian affairs.
