Individual investors select high-fee index mutual funds despite the fact that the future payouts are nearly identical. The authors offer an explanation for this violation of the law of one price based on investor desire to diversify. While diversification in some settings may be beneficial, in the case of assets with identical payouts, fee minimization is the only rational strategy. The evidence confirms that investors diversify by selecting multiple higher fee funds rather than minimizing fees when investing in index mutual funds. 相似文献

The paper investigates determinants of pricing in international telephone service markets. The analysis—focused on 24 worldwide
national markets—shows the impact of several telecommunications-specific and macroeconomic variables on collection rate differentials
and traffic imbalance between countries. An econometric model is aimed at performing quantitative analysis and providing support
to future telecommunications policies. 相似文献

This paper analyses the regulation of the market of voice call termination on mobile networks, by considering the remedy of
asymmetric access charges and the hypothesis of discriminatory retail pricing. In the two way interconnection, the operators
revenue depends on two factors: the retail price and the access charge. If the retail prices are different between calls that
terminate on the same network (on-net) and calls that terminate on the rival network (off-net), the competition is more complex,
involving positive networks externalities for the incumbent operator. In order to reduce the competitive disadvantage for
new entrants and smaller operators many European regulation authorities have introduced the remedy of asymmetric access charges.
This paper is aimed at analysing the effectiveness of this regulatory measure, assuming that operators are differentiated
in terms of brand loyalty and cost structure. 相似文献

Brand alliances long have been used in the private sector and are being more frequently engaged by nonprofit organizations. It is assumed that the alliance benefits both organizations, particularly the focal nonprofit organization that strategically forms the partnership. But care must be taken in selecting partners. A quasi‐experimental design examines the relationship between partner reputation and sector (private or nonprofit) on subject willingness to contribute to a focal nonprofit organization. Partner public reputation was systematically varied using created organizations and a positive reputation enhanced willingness to contribute. Partnering with private sector organizations was only slightly less desirable than nonprofit organizations. 相似文献

Consider a linear regression model and suppose that our aim is to find a confidence interval for a specified linear combination of the regression parameters. In practice, it is common to perform a Durbin–Watson pretest of the null hypothesis of zero first‐order autocorrelation of the random errors against the alternative hypothesis of positive first‐order autocorrelation. If this null hypothesis is accepted then the confidence interval centered on the ordinary least squares estimator is used; otherwise the confidence interval centered on the feasible generalized least squares estimator is used. For any given design matrix and parameter of interest, we compare the confidence interval resulting from this two‐stage procedure and the confidence interval that is always centered on the feasible generalized least squares estimator, as follows. First, we compare the coverage probability functions of these confidence intervals. Second, we compute the scaled expected length of the confidence interval resulting from the two‐stage procedure, where the scaling is with respect to the expected length of the confidence interval centered on the feasible generalized least squares estimator, with the same minimum coverage probability. These comparisons are used to choose the better confidence interval, prior to any examination of the observed response vector. 相似文献

I examine the relationship between bargaining leverage and capital investment using data on California’s hospital markets. I find evidence that investment increases with bargaining leverage; a hospital whose bargaining position improves by one standard deviation will increase its investment rate by 16 percentage points. A positive causal relationship between bargaining leverage and investment fits the institutional details of the health care sector, where many firms have non-profit tax status, making it difficult to return monopoly rents to shareholders. Consistent with this explanation, I find that non-profit hospitals with bargaining leverage invest more than for-profit ones, all else equal. I do not find strong evidence that financing constraints matter disproportionately for hospitals operating in more competitive markets, supporting the hypothesis that the incremental investment may not be socially efficient. 相似文献

During the past few years, hospitals have been actively evaluating the use of newer-type stocking systems for their pharmacies. While "stockless," a just-in-time (JIT) variation, appears to be emerging as perhaps the most promising method, it is far from being accepted as the industry standard. Because of growing concern for health care reform, with its cost containment component, it may well be anticipated that both the pace and profoundness of these efforts will continue to intensify. 相似文献
