We construct new measures of fund style, performance and activity from linear combinations of off‐the‐shelf stock‐market indices. A fund's benchmark portfolio is a linear combination of two or more reference portfolios that in a least‐squares sense most closely approximates the fund's portfolio. The resulting linear combination scalar is itself a measure of fund style and the distance between a fund and its benchmark is a measure of fund activity. Our approach has a number of advantages over existing characteristic‐matching methods. We illustrate our approach using a data set of US institutional funds.  相似文献

This paper presents tests of the theoretical validity of the contingent valuation (CV) method. The validity of CV is especially a concern when involving environmental goods with a predominant non-use value. One test of theoretical validity is the adding-up property that implies that a specific good should be equally valued irrespectively of it is being valued directly or built-up sequentially. In this CV study four independent sub-samples stated willingness to pay for the same composite good, or package, using different sequences. One sub-sample valued the composite good directly, while two sub-samples faced built-up sequences valuing first subsets of this composite good. A fourth sub-sample valued the composite good from a dividing-out approach, facing first the valuation of a larger multi-package. Theoretically expected sequencing effects were observed; the subset goods obtained higher values earlier in a sequence, and the dividing-out approach decreased the stated value for the composite good. Most importantly, these CV data did pass the tests of the adding-up property.  相似文献

This paper uses a two-step estimation procedure suggested by Sherwin Rosen to estimate structural demand and supply equations for urban air quality. In the first step, a hedonic price equation is estimated for residential property values for the Washington, D. C., SMSA for 1970. In the second step, a set of marginal hedonic prices is generated. These prices and the quantity of clean air (reciprocal of air pollution) are used as endogenous variables in a simultaneous equation model. Empirical results indicate a price elasticity of demand between ?1.2 and ?1.4 and a unitary income elasticity.  相似文献

Although the purchase of a home represents a sizable investment for the average family, relatively little consumer research pertaining to the home purchase process has been reported. This investigation utilized Thurstone's Case V methodology to identify key attributes used by consumers to make housing choices and to show how these attributes are perceived by consumers of different tenure and socioeconomic status. The pairwise comparison analysis showed a strong preference for the attributes “safety and security from crime” and “quality construction” by the respondents. In addition, the analysis revealed several important differences in attribute preferences between former owners and former renters. Former home owners, for example, were more likely than former renters to prefer school quality when it was pitted against several other attributes. Thurstone's Case V techniques was found to be an effective method for measuring consumer preferences. Implications which focus on home product development and marketing strategies are discussed.  相似文献

In 1993, Californians voted on a school voucher initiative. We hypothesize that homeowners in good school districts understood the voucher to be a threat to their property values and thus voted against it. Precinct returns from Los Angeles County confirm this hypothesis. We also examine an alternative hypothesis explaining the relationship between school quality and precinct returns. According to the alternative, voters perceived the initiative to be a referendum on public school quality. To distinguish between the two hypotheses, we compare the voting patterns of homeowners and renters. The comparison does not favor one hypothesis over the other.  相似文献

There is substantial evidence on the importance of education as a driver of earnings, productivity, and economic growth. However, knowledge of the specific role of associate's degrees in U.S. economic growth is limited. We analyze the sources of U.S. economic growth and identify the contribution of associate's degree holders to improvements in earnings, labor quality, productivity, and overall economic growth. We find evidence that substitution toward workers with associate's degrees has increased U.S. earnings, aggregate labor quality, and productivity, and that these effects are concentrated in the health care, trade, and government sectors. While the average educational attainment of people entering the labor force has plateaued, our results suggest that shifting workers from some college to associate degrees could improve earnings, the quality of the workforce, productivity, and growth, potentially without more time spent in school.  相似文献
