The method of principal component is used in this paper to analyse the interrelationship among the world's major stock exchanges. The major finding is that the interrelationship is unstable over time. This finding proves that any ex ante prediction of price indices is impossible, and it suggests that the indices of world equity markets can move in a random walk fashion. The consequences to international portfolio diversification should be obvious. 相似文献

IMPACT OF PRICING STRUCTURE SELECTIVITY ON URBAN WATER DEMAND 总被引:1,自引:0,他引:1
Interest in demand management policies has intensified as residential water demand has grown in the United States. Using data from the 1984 American Water Works Association (AWWA) survey, the study here provides an empirical analysis of the differences in price elasticities of demand across water pricing block structures and examines these structures' "conservation-orientedness." However, a potential sample selection bias exists. That is, in cities where people are more interested in conservation, utility managers may be more likely to select a rate structure that they believe is conservation-oriented–an increasing block structure, for example. Managers' selectivity bias may cause research results either to understate or to overstate a particular block structure's impact on water conservation. The analysis here corrects for this selectivity bias in estimating water demand and tests whether consumers respond to average prices or to marginal prices. Correcting for selectivity bias involves an explicit analysis of the factors that influence utility managers' selection of rate structures. Estimating water demand under increasing and decreasing block structures suggests that sample selection bias remains a problem worthy of further investigation. 相似文献

We investigate the factors that contribute to participation in the Supplemental Nutrition Assistance Program (SNAP, formerly known as the Food Stamp Program) and the effects of such participation on self‐assessed health (SAH). Our estimation approach consists of an endogenous switching ordered probability model, using the copula approach, for a sample of current and former Temporary Assistance for Needy Families (TANF) recipients in Tennessee. Results indicate that sociodemographic characteristics play a role in SNAP participation. Interestingly, we find that participation in SNAP is inversely related to SAH. (JEL I12, I38, C31) 相似文献

We evaluate the manner in which sponsors of highly leveraged asset‐backed commercial paper (ABCP) conduits responded to Financial Accounting Standards Board Interpretation No. 46 (FIN 46), Consolidation of Variable Interest Entities an Interpretation of ARB No. 51, and its Canadian counterpart Accounting Standards Board of Accounting Guideline 15 (AcG‐15), Consolidation of Variable Interest Entities. By matching commercial paper investors with corporations seeking liquidity, ABCP sponsors facilitate a significant amount of short‐term, securitized financing in the United States. FIN 46 and AcG‐15 require sponsors to consolidate their ABCP conduits with their financial statements. We demonstrate that the volume of ABCP began to decline when FIN 46 was first proposed, and that this decline is primarily attributable to a reduction in North American banks' sponsorship of ABCP. We also demonstrate that North American banks entered into costly restructuring arrangements to avoid having to consolidate their conduits per the new accounting standards. Our results suggest that, in certain settings, accounting standards appear to have real effects on investment activity and product‐market competition. 相似文献

The financing of R&D provides a potentially important channel to link finance and economic growth, but there is no direct evidence that financial effects are large enough to impact aggregate R&D. U.S. firms finance R&D from volatile sources: cash flow and stock issues. We estimate dynamic R&D models for high-tech firms and find significant effects of cash flow and external equity for young, but not mature, firms. The financial coefficients for young firms are large enough that finance supply shifts can explain most of the dramatic 1990s R&D boom, which implies a significant connection between finance, innovation, and growth. 相似文献

This paper measures the efficiency and revenue properties of the two most popular formats for divisible goods auctions: the uniform‐price and discriminatory auction. We analyze bids into the Korean Treasury auctions which have used both formats. We find that the discriminatory auction yields statistically higher revenue. Unlike previous work that uses data from only one format, we are able to compare the efficiency properties of the two formats. We find that the discriminatory auction better allocates treasury bills to the highest value financial institutions. However, the differences in revenue and efficiency are not large because the auctions are very competitive. 相似文献

This article focuses on the historical experience with U.S. external adjustment, that is, narrowings of the trade deficit. Using data from the past 35 years, we compare economic performance in episodes during which the U.S. trade balance declined against episodes during which it rose. We find that trade balance adjustment has been generally benign: U.S. real gross domestic product growth tended to fall but not to a statistically significant extent; housing construction slumped; inflation generally rose modestly; and although nominal interest rates tended to rise, real interest rates fell. The article then compares these outcomes to those in foreign industrial economies. We find that the economic performance of the United States during periods of external adjustment is remarkably similar to the foreign experience. Finally, we also examine the performance of the foreign industrial economies during the periods when the U.S. trade deficit widened and narrowed. Contrary to concerns that U.S. adjustment will prove injurious to foreign economies, our analysis suggests that the foreign economies fared reasonably well during past periods when the U.S. trade deficit narrowed.

This paper investigates optimal fiscal policy in a static multisector model. A Ramsey type planner chooses tax rates on each good type as well as spending levels on each good type subject to an exogenous total expenditure constraint. It is shown that, like taxes, government spending policy has price effects and that these price effects have significant implications for optimal policy. These price effects imply a U shape to the government's objective function and this U shape results in boundary values for the choice of the spending allocation. In particular, it is shown that the optimal allocation of government spending tends to be concentrated on one good rather than spread among many goods. 相似文献

While interest in financial management training programs for low‐income persons has grown in recent years, the specific training needs of low‐income consumers have not been well articulated. This article describes needed training content for such audiences, based on review of previous research and the authors’ experiences in evaluating the Financial Links for Low‐Income People (FLLIP) program. We also illustrate how the choice of financial management training models can seriously impact the subgroups of the low‐income population who attend training, as well as the success of programs in recruiting and graduating participants. The implications of these findings both for financial management curriculum development and for the selection of program models are presented. 相似文献
