Gross stocks of foreign assets have increased rapidly relative to national outputs since 1990, and the short-run capital gains
and losses on those assets can amount to significant fractions of GDP. These fluctuations in asset values render the national
income and product account measure of the current account balance increasingly inadequate as a summary of the change in a
country's net foreign assets. Nonetheless, unusually large current account imbalances, especially deficits, should remain
high on policymakers' list of concerns, even, for the richer and less credit-constrained countries. Extreme imbalances signal
the need for large and perhaps abrupt real exchange rate changes in the future, changes that might have undesired political
and financial consequences given the incompleteness of domestic and international asset markets. Furthermore, of the two sources
of the change in net foreign assets—the current account and the capital gain on the net foreign asset position—the former
is better understood and more amenable to policy influence. Systematic government attempts to manipulate international asset
values in order to change the net foreign asset position could have a destabilizing effect on market expectations. JEL no.

Liquidity risk and arbitrage pricing theory 总被引:2,自引:0,他引:2
Classical theories of financial markets assume an infinitely liquid market and that all traders act as price takers. This theory is a good approximation for highly liquid stocks, although even there it does not apply well for large traders or for modelling transaction costs. We extend the classical approach by formulating a new model that takes into account illiquidities. Our approach hypothesizes a stochastic supply curve for a securitys price as a function of trade size. This leads to a new definition of a self-financing trading strategy, additional restrictions on hedging strategies, and some interesting mathematical issues.Received: 1 November 2003, Mathematics Subject Classification:

Abstract: This study analyses whether stock indices that represent socially responsible investments (SRI) exhibit a different performance compared to conventional benchmark indices. In contrast to other studies, the analysis concentrates on SRI indices and not on investment funds. This has several advantages, since transaction costs of funds, the timing activities and the skill of the fund management do not have to be considered. A direct measure of the performance effects of SRI screens is therefore examined. The 29 SRI stock indices are analysed by single-equation models as well as by multi-equation systems that exploit the information in the cross-section. SRI stock indices do not exhibit a different level of risk-adjusted return than conventional benchmarks. But many SRI indices have a higher risk relative to the benchmarks. The findings are robust to the use of different benchmark indices and apply to all common types of SRI screening. 相似文献

We explore the ability of alternative popular continuous-time diffusion and jump-diffusion processes to capture the dynamics of implied volatility indices over time. The performance of the various models is assessed under both econometric and financial metrics. To this end, data are employed from major European and American implied volatility indices and the rapidly growing CBOE volatility futures market. We find that the addition of jumps is necessary to capture the evolution of implied volatility indices under both metrics. Mean reversion is of second-order importance though. The results are consistent across the various metrics, markets, and construction methodologies. 相似文献

This study proposes that international joint ventures (IJVs) are terminated either when the initial purposes of the formation of the IJV have been achieved (intended termination), or when unanticipated contingencies that emerge in the external, internal, or inter‐partner conditions after the establishment of the IJV impede the continuation of its operation (unintended termination). Our study examines the factors that affect intended and unintended termination and the longevity of IJVs. The findings show that approximately 90 percent of all IJV terminations are unintended and 10 percent intended, and that the frequency of intended termination and unintended termination varies noticeably depending on the initial purposes of formation. This suggests that the termination of IJVs is significantly contingent on their formation. The findings also show that the longevity of IJVs varies according to the initial purposes of formation, the initial conditions under which the IJV is formed, and the types of unanticipated contingencies that it encounters. The key theoretical issues and practical implications of the distinction between the intended and unintended termination of IJVs are also discussed. Copyright © 2007 John Wiley & Sons, Ltd. 相似文献

从社会主义社会基本矛盾运行轨迹的角度,认为应把生产资料所有制这个经济基础的范畴,从上层建筑领域彻底剥离出来,把国营企业改名为全民所有制企业,把国家资产管理委员会改为全民资产管理委员会,从而在社会主义制度的经济体制、机制和运行方式上彻底割断政企不分、条块分割的经济纽带,建立起科学的名副其实的生产资料全民所有制和全民所有制企业。 相似文献

We use Demographic and Health Surveys (DHS) to compare “poverty” at two or more points in time within and between African countries. Our welfare measure is an index resulting from a factor analysis of various household characteristics, durables, and household heads’ education. An advantage of this measure is that for intertemporal and intraregional comparisons, we need not rely on suspect price deflators and currency conversion factors. The wide availability and similarity of questionnaires of the DHS facilitate comparisons over both time and countries. Our results generally show declines in poverty during the previous decade, largely due to improvements in rural areas. 相似文献

Measuring the immeasurable — A survey of sustainability indices 总被引:1,自引:0,他引:1
Sustainability indices for countries provide a one-dimensional metric to valuate country-specific information on the three dimensions of sustainable development: economic, environmental, and social conditions. At the policy level, they suggest an unambiguous yardstick against which a country's development can be measured and even a cross-country comparison can be performed. This article reviews the explanatory power of various sustainability indices applied in policy practice. We show that these indices fail to fulfill fundamental scientific requirements making them rather useless if not misleading with respect to policy advice. 相似文献
