Foreign Exchange Volume: Sound and Fury Signifying Nothing?

This paper examines whether currency trading volume is informative, and under what circumstances. Specifically, we use transactions data to test whether trades occurring when trading intensity is high are more informative - dollar for dollar - than trades occurring when intensity is low. Theory admits both possibilities, depending primarily on the posited information structure. We present what we call a hot-potato model of currency trading, which explains why low-intensity trades might be more informative. In the model, the wave of inventory-management trading among dealers following innovations in order flow generates an inverse relationship between intensity and information content. Empirically, low-intensity trades are more informative, supporting the hot-potato hypothesis."

Foreign exchange: macro puzzles, micro tools

This paper reviews recent progress in applying information-theoretic tools to long-standing exchange rate puzzles. I begin by distinguishing the traditional public information approach (e.g., monetary models, including new open-economy models) from the newer dispersed information approach. (The latter focuses on how information is aggregated in the trading process.) I then review empirical results from the dispersed information approach and relate them to two key puzzles, the determination puzzle and the excess volatility puzzle. The dispersed information approach has made progress on both.Foreign exchange rates

A New Micro Model of Exchange Rate Dynamics

We address the exchange rate determination puzzle by examining how information is aggregated in a dynamic general equilibrium (DGE) setting. Unlike other DGE macro models, which enrich either preference structures or production structures, our model enriches the information structure. The model departs from microstructure-style modeling by identifying the real activities where dispersed information originates, as well as the technology by which information is subsequently aggregated and impounded. Results relevant to the determination puzzle include: (1) persistent gaps between exchange rates and macro fundamentals, (2) excess volatility relative to macro fundamentals, (3) exchange rate movements without macro news, (4) little or no exchange rate movement when macro news occurs, and (5) a structural-economic rationale for why transaction flows perform well in accounting for monthly exchange rate changes, whereas macro variables perform poorly. Though past micro analysis has made progress on results (1) through (3), results (4) and (5) are new. Excess volatility arises in our model for a new reason: rational exchange rate errors feed back into the fundamentals that the exchange rate is trying to track.

The Role of External Economies in U.S. Manufacturing

This paper develops a method for joint estimation of both the degree of internal returns to scale and the extent of external economies. We apply the method in estimating returns to scale indexes for U.S. manufacturing industries at the two-digit level. Overall, we find that only three of the twenty industry categories show any evidence of internal increasing returns: (1) Primary Metals, (2) Electrical Machinery, and (3) Paper Products. More striking, however, is the very strong evidence of the existence of external economies, where external is defined as external to a given two-digit industry and internal to the U.S.. According to our preferred estimates, if all manufacturing industries simultaneously raise their inputs by 10%, aggregate manufacturing production rises by 13%, of which about 5% is due to external economies. Thus, when an industry increases its inputs in isolation by 10%, its output rises by no more than 8%.

Do Currency Markets Absorb News Quickly?

This paper addresses whether macro news arrivals affect currency markets over time. The null from macro exchange-rate theory is that they do not: macro news is impounded in ex-change rates instantaneously. We test this by examining the effects of news on subsequent trades by end-user participants (such as hedge funds, mutual funds, and non-financial corporations). News arrivals induce subsequent changes in trading in all of the major end-user segments. These induced changes remain significant for days. Induced trades also have persistent effects on prices. Currency markets are not responding to news instantaneously.

Informational Integration and FX Trading

This paper addresses international financial integration in a new way. We focus on informational integration, specifically, the importance of information conveyed by order flow in major currencies for pricing minor currencies. We develop a multi-currency model of portfolio allocation in the presence of dispersed information. We then test the modelÂ’s implications using four months of concurrent transaction data on nine currencies. The model explains 45 to 78 percent of daily returns in all nine currencies. Moreover, its prediction that order flow in individual markets should be relevant for determining prices in other markets is borne out.Exchange Rates, Order flow, Financial Integration

Mutual fund investment in emerging markets - an overview

International mutual funds are one of the main channels for capital flows to emerging economies. Although mutual funds have become important contributors to financial market integration, little is known about their investment allocation, and strategies. The authors provide an overview of mutual fund activity in emerging markets. First, they describe international mutual funds'relative size, asset allocation, and country allocation. Second, they focus on fund behavior during crises, by analyzing data at the level of both investors, and fund managers. Among their findings: Equity investment in emerging markets has grown rapidly in the 1990s, much of it flowing through mutual funds. Collectively, these funds hold a sizable share of market capitalization in emerging economies. Asian, and Latin American funds achieved the fastest growth, but are smaller than domestic U.S. funds and world funds. When investigating abroad, U.S. mutual funds invest more in equity than in bonds. World funds invest mainly in developed nations (Canada, Europe, Japan, and the United States). Ten percent of their investment is in Asia, and Latin America. Mutual funds usually invest in a few countries within each region. Mutual fund investment was very responsive to the crises of the 1990s. Withdrawals from emerging markets during recent crises were large, which squares with existing evidence of financial contagion. Investments in Asian, and Latin American mutual funds are volatile. Because redemptions, and injections are large, relative to total funds under management, fund's flows are not stable. The cash held by managers during injections, and redemptions does not fluctuate significantly, so investors'actions are typically reflected in emerging market inflows, and outflows.International Terrorism&Counterterrorism,Infrastructure Finance,Infrastructure Finance,Economic Theory&Research,Financial Intermediation
