This article re–evaluates the gravity of the financial problems facing British voluntary hospitals in the interwar period. A relational database of statistics on hospital provision, finance (at both current and constant prices), and activity is used to derive consistent sets of hospitals for reporting purposes. The article presents novel analyses of the extent and pattern of hospital surpluses and deficits; of the capital accounts of selected individual hospitals; of trends in hospital expenditure; of the diversification of hospital income, emphasizing the declining importance of traditional philanthropy; and of the effect of these changes on hospital provision and utilization. 相似文献

由于缺乏可担保的资产和经营业绩的历史纪录,初创企业难以从外界获取资金,风险投资就成为其主要的融资途径,但许多创业者在寻求风险投资的支持时,担心风险投资的加入会稀释他们的股权,使他们的利益旁落。诚然,风险投资家在向创业企业注资时,往往要求苛刻,在股权分配上尽量提高自己的分配份额。风险投 相似文献

In the process of coding open-ended questions, the evaluation of interjudge reliability is a critical issue. In this paper,
using real data, the behavior of three coefficients of reliability among coders, Cohen’s K, Krippendorff’s α and Perreault and Leigh’s I
r
are patterned, in terms of the number of judges involved and the categories of answer defined. The outcome underlines the
importance of both variables in the valuations of interjudge reliability, as well as the higher adequacy of Perreault and
Leigh’s I
r
and Krippendorff’s α for marketing and opinion research. 相似文献

The purpose of this paper is to analyse the relationship between the corporate governance system and technical efficiency in Italian manufacturing. We use a non‐parametric frontier technique (DEA) to derive technical efficiency measures for a sample of Italian firms taken from nine manufacturing industries. These measures are then related to the characteristics of the corporate governance system. Two of these characteristics turn out to have a positive impact on technical efficiency: the percentage of the company shares owned by the largest shareholder and the fact that a firm belongs to a pyramidal group. Interestingly, a trade‐off emerges between these influences, in the sense that one is stronger in industries where the other is weaker. Copyright © 2007 John Wiley & Sons, Ltd. 相似文献

SELECTION BIAS CORRECTIONS BASED ON THE MULTINOMIAL LOGIT MODEL: MONTE CARLO COMPARISONS 总被引:2,自引:0,他引:2
Abstract. This survey presents the set of methods available in the literature on selection bias correction, when selection is specified as a multinomial logit model. It contrasts the underlying assumptions made by the different methods and shows results from a set of Monte Carlo experiments. We find that, in many cases, the approach initiated by Dubin and MacFadden (1984) as well as the semi-parametric alternative recently proposed by Dahl (2002) are to be preferred to the most commonly used Lee (1983) method. We also find that a restriction imposed in the original Dubin and MacFadden paper can be waived to achieve more robust estimators. Monte Carlo experiments also show that selection bias correction based on the multinomial logit model can provide fairly good correction for the outcome equation, even when the IIA hypothesis is violated. 相似文献

Within the standard Keynesian multiplier framework, extended by a micro-model of interactive formation of individual consumption
propensities, we demonstrate that socioeconomic interactions can lead to cyclical fluctuations in aggregate economic activity.
The underlying micro-model of direct interactions is a version of Alan Kirman’s generic opinion formation model, with an additional
feedback effect from macroscopic variables on the transition probabilities. Our model engenders cyclical fluctuations of economic
variables, despite the fact that neither the Keynesian multiplier model nor Kirman’s model does so on its own. 相似文献

Measuring volatility with the realized range 总被引:1,自引:0,他引:1
Realized variance, being the summation of squared intra-day returns, has quickly gained popularity as a measure of daily volatility. Following Parkinson [1980. The extreme value method for estimating the variance of the rate of return. Journal of Business 53, 61–65] we replace each squared intra-day return by the high–low range for that period to create a novel and more efficient estimator called the realized range. In addition, we suggest a bias-correction procedure to account for the effects of microstructure frictions based upon scaling the realized range with the average level of the daily range. Simulation experiments demonstrate that for plausible levels of non-trading and bid–ask bounce the realized range has a lower mean-squared error than the realized variance, including variants thereof that are robust to microstructure noise. Empirical analysis of the S&P500 index-futures and the S&P100 constituents confirms the potential of the realized range. 相似文献

This study examines whether independent directors who possess financial expertise and are independent from the CEO (i.e., non-co-opted) are associated with improved outcomes for industry superannuation funds. Our results highlight that independence alone is insufficient to improve fund outcomes. Instead, we find that only non-co-opted independent directors benefit fund members in terms of higher performance and lower fees. Moreover, we find that independent directors' financial expertise is not associated with fund performance and fees. Our study has implications for regulators and superannuation funds who are currently debating the need for one-third independent directors on the board of Australian superannuation funds. 相似文献

This article develops and tests a conceptual model of the transfer process whereby perceived similarity organized around shared
goals facilitates the transfer of knowledge and affect from a parent brand to an extension of that brand. Empirical results,
based on two well-known brands and two hypothetical product extensions for each brand, demonstrate that the availability of
well-formed, goal-derived categories associated with a parent brand establishes an organizing framework for consumers' assessments
of similarity thatfacilitates the transfer of consumer knowledge and attitude from the parent brand to a brand extension in
another product category. This facilitating effect of similarity does not occur in the absence of goal-derived categories.
The results also reveal how marketing communication can be used to facilitate the transfer process by framing similarity in
terms of common goals. Implications are discussed for the organization of consumer knowledge and affect across product categories
and for understanding prior research findings on brand extension.
