Policymakers in emerging markets are increasingly concerned about the consequences for the domestic equity market when companies list stock abroad. We show that the effects of cross-listing depend on the quality of intermarket information linkages. We investigate these issues with unique data from the Mexican equity market. The impact of cross-listing is complex-balancing the costs of order f low migration against the benefits of increased intermarket competition. These effects are exacerbated by equity investment barriers that induce segmentation of the domestic equity market. Consequently, the benefits and costs of cross-listing are not evenly spread over all classes of shareholders. THERE HAS BEEN A DRAMATIC INCREASE in the trading of foreign stocks as investors recognize the need for international diversification and as foreign companies seek to broaden their shareholder base and raise capital. As a result, the number of American Depository Receipt~ADR! listings on U.S. exchanges has also risen sharply. Though corporations view cross-listings as value enhancing, the changes in liquidity and volatility, and the cost of trading associated with order f low migration following cross-listing may adversely affect the quality of the domestic equity market. Such changes are especially important for emerging markets facing new competition from wellestablished, highly liquid markets abroad, and are the source of increasing concern among policymakers. There is also considerable academic interest in this topic, especially because the effects of cross-listing may be related to the * Domowitz is from Northwestern University, Glen is with the International Finance Corporation, and Madhavan is at the University of Southern California.

Actual investment performance reflects the underlying strategy of the portfolio manager and the execution costs incurred in realizing those objectives. Execution costs, especially in illiquid markets, can dramatically reduce the notional return to an investment strategy. This paper examines the interactions between cost, liquidity and volatility, and analyses their determinants using panel data for 42 countries from September 1996 to December 1998. We document wide variation in trading costs across countries; emerging markets, in particular, have significantly higher trading costs even after correcting for factors such as market capitalization Goldman Sachs Asset Management provided many useful comments.

We analyse the inter-relationships between turnover, equity trading costs and volatility, and investigate the impact of these variables on equity returns. In particular, we show that increased volatility, acting through costs, reduces a portfolio's expected return. However, higher volatility reduces turnover also, mitigating the actual impact of higher costs on returns. Further, turnover is inversely related to trading costs, providing a possible explanation for the increase in turnover in recent years. The results demonstrate that the composition of global efficient portfolios can change dramatically when cost and turnover are taken into account.

In this paper, we examine the performance of a sample of fifteen U.S.‐based internationally diversified mutual funds between 1982 and 1988. Two performance measures are used, the Jensen measure and the positive period weighting measure proposed by Grinblatt and Titman. We find no evidence that the funds, either individually or as a whole, provide investors with performance that surpasses that of a broad, international equity index over this sample period.

This paper examines the benefits from currency hedging, both for speculative and risk minimization motives, in international bond and equity portfolios. The risk‐return performances of globally diversified portfolios are compared with and without forward contracts. Over the period 1974 to 1990, inclusion of forward contracts results in statistically significant improvements in the performance of unconditional portfolios containing bonds. Conditional strategies are also implemented, both in sample and out of sample, and are shown to both significantly improve the risk‐return tradeoff of global portfolios and to outperform unconditional hedging strategies.
