U.S. Equity Investment in Emerging Stock Markets 总被引:2,自引:0,他引:2
This article examines U.S. equity flows to emerging stock marketsfrom 1978 to 1991 and draws three main conclusions. First, despitethe recent increase in U.S. equity investment in emerging stockmarkets, the U.S. portfolio remains strongly biased toward domesticequities. Second, of the fraction of the U.S. portfolio thatis allocated to foreign equity investment, the share investedin emerging stock markets is roughly proportional to the shareof the emerging stock markets in the global market capitalizationvalue. Third, the volatility of U.S. transactions in emerging-marketequities is higher than in other foreign equities. The normalizedvolatility of U.S. transactions appears to be falling over time,however, and we find no relation between the volume of U.S.transactions in foreign equity and local turnover rates or volatilityof stock returns. 相似文献

The Euro US Dollar rate is one of the most important exchange rates in the world, making the analysis of its behavior fundamental for the global economy and for different decision‐makers at both the public and private level. Furthermore, given the market efficiency of the EUR/USD exchange rate, being able to predict the rate's future short‐term variation represents a great challenge. This study proposes a new framework to improve the forecasting accuracy of EUR/USD exchange rate returns through the use of an Artificial Neural Network (ANN) together with a Vector Auto Regressive (VAR) model, Vector Error Corrective model (VECM), and post‐processing. The motivation lies in the integration of different approaches, which should improve the ability to forecast regarding each separate model. This is especially true given that Artificial Neural Networks are capable of capturing the short and long‐term non‐linear components of a time series, which VECM and VAR models are unable to do. Post‐processing seeks to combine the best forecasts to make one that is better than its components. Model predictive capacity is compared according to the Root Mean Square Error (RMSE) as a loss function and its significance is analyzed using the Model Confidence Set. The results obtained show that the proposed framework outperforms the benchmark models, decreasing the RMSE of the best econometric model by 32.5% and by 19.3% the best hybrid. Thus, it is determined that forecast post‐processing increases forecasting accuracy. 相似文献

The disequilibria in the world economy, of which the massive trade and current account deficits of the USA are but one manifestation, have reached dangerous proportions. The following article presents a number of scenarios to show how they may develop in future. 相似文献

This paper analyses an exchange economy in the absence of Arrow-Debreu complete markets. It is assumed that trading takes place in the sequence of spot markets and futures markets for securities payable in units of account. Unlimited short-selling in securities is allowed. A general equilibrium in such an economy is a set of current and future prices (contingent on uncertain events) and a set of individual plans such that all markets are cleared. The existence of such an equilibrium is proved under usual assumptions. This is in contrast to the case of futures markets for contingent futures commodities where an equilibrium may not exist. The optimality of equilibrium allocations is also discussed. 相似文献

With the completion of the single European market steps are to be made towards eliminating remaining impediments to the free movement of labour between Community countries such as an inadequate flow of information or the non-recognition of educational or training qualifications. How do companies respond to the extension of national labour markets by a European component? 相似文献

To a growing extent, since the early 1970s “new forms” of foreign investment have developed which constitute a departure from full ownership of the capital by the foreign investor and the practice of “packaged” management services. What view is to be taken of these new forms of investment from the development policy aspect? 相似文献
