This study analyzes the performance effects of proprietary, multihospital systems. It is shown that the organizational structure of these systems may affect the operating costs of member hospitals. Estimating a cost function for Florida hospitals and controlling for other factors, the average costs of HUMANA hospitals are empirically about 17 percent lower, while the costs of other leading chains are about 12 percent lower than not-for-profit institutions. These results contrast with earlier studies that found no such differences. Furthermore, the cost differential that exists between system and non-system hospitals can be largely attributed to technical efficiencies arising from chain ownership. 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

Brands matter: An empirical demonstration of the creation of shareholder value through branding 总被引:1,自引:0,他引:1
Thomas J. Madden Frank Fehle Susan Fournier 《Journal of the Academy of Marketing Science》2006,34(2):224-235
This research responds to the attendant need for empirical evidence pertaining to how marketing affects firm performance.
Using the Fama-French method, common in finance, and a leading marketplace measure of a brand’s financial equity value, the
authors provide empirical evidence for the branding-shareholder value creation link. The results extend previous research
by showing that strong brands not only deliver greater returns to stockholders than does a relevant benchmark but do so with
less risk This finding holds even when market share and firm size are considered.

Research in Motion's (RIM's) entry into the Chinese market during a time when many distractions —principally a patent dispute with NTP—occupied management's attention was not a foregone conclusion. China remained a difficult market to crack. One holdup was an impasse with regard to RIM's use of encryption technology and the Chinese authorities' desire to monitor e‐mail traffic and content. Here the technical and political concerns were entangled. To further complicate things, the entirety of RIM had until recently been preoccupied with the legal settlement with NTP in the United States. Issues in this study highlight real‐world dilemmas in a thriving firm. The founders are still in charge, and new markets present themselves regularly. A very real challenge is divided attentions. The standstill over market entry calls for integrative thinking—bringing together disparate and contradictory elements for resolution. RIM's way out will invariably involve embracing complex relationships in order to find a resolution to the various conflicting institutional forces. © 2008 Wiley Periodicals, Inc. 相似文献

Reviving brand loyalty: A reconceptualization within the framework of consumer-brand relationships 总被引:1,自引:0,他引:1
This paper uses the perspective of interpersonal relationship theory to critically examine, reposition, and extend the notion of brand loyalty. Depth interviews among eight coffee-consuming adults who qualified as brand loyal by traditional criteria provide the data. The result is a deeper appreciation of the character of loyal consumer-brand relations and a sharper awareness of the limitations to understanding that current theoretical frameworks impose. Specifically, the authors suggest that: (1) not all loyal brand relationships are alike, in strength or in character; (2) many brand relationships not identified as ‘loyal’ according to dominant theoretical conceptions are especially meaningful from the cunsumer's point of view; and (3) current approaches to classification accept some brand relationships that, upon close scrutiny, do not possess assumed characteristics of ‘loyalty’ or ‘strength’ at all. Ideas stemming from a reframing of loyalty as one component in a multifaceted construct of relationship strength are put forth, encouraging a move from the metaphor of ‘loyalty’ to the broader notion of ‘relationships’ that encompasses it. 相似文献

Certificate‐of‐Need (CON) programs for new hospital construction are intended to foster the best selection among competing hospital applications, given demands for hospital care in the community. Yet, the merits of CON depend in part on the quality of the comparative review process. This article examines a case study in Florida to illustrate the utility of empirical evaluations using patient choice models. I estimate such models to show how patients would respond to a change in hospital choices. By simulating the welfare effects of the proposed hospitals, I can further predict how prices of hospital care differ by applicant. Results suggest that empirical analysis using data on patient choice of hospitals may better inform the review process. At the same time, however, it may not give a unique ranking without additional analysis of the fixed costs of proposed services in the context of existing marketwide capacity. 相似文献

Although researchers and practitioners have access to a growing body of evidence on the effects of electronic word-of-mouth (eWOM) frequency and valence, a more detailed understanding of eWOM content is needed in order to better influence these social media-enabled conversations. Based on an ethnomethodological analysis of community conversations in a popular parenting online forum, we reveal that eWOM is a powerful social act in which consumers use a broad repertoire of eWOM rhetorical methods. The repertoire for advice-seeking talk includes five components: seeker's legitimacy, topic legitimacy, request formulation, solicitation of responders, and requested response framing. The repertoire for advice-giving includes four components: foundation of authority, advice framing, advice focus, and advice scheme. For each of these components in the two repertoires, we identify corresponding rhetorical methods that can be used in the conversation (over 30 methods in total). Preliminary evidence also suggests that rhetorical alignment between advice-seekers and givers drives effectiveness of eWOM advice. The proposed rhetorical framework has relevance and implication for the many areas where social media and marketing meet. 相似文献

中国企业的工资差异和所有制结构 总被引:18,自引:1,他引:17
本文采用OaxacaBlinder分解法的扩展形式,分析了1995年中国城市不同所有制企业间工资差异的决定因素。我们发现,国有企业和外商投资企业工资高于城镇集体企业,但中央直属国有企业和外商投资企业的小时工资鲜有差别。此外,我们的研究结果强有力地证明了,中国劳动力市场的分割或者说是多层次、纯所有制差别和工作小时差别是观测到的工资差距的主要决定因素。我们的研究结果还强调了,尽管外商投资企业提供了较高的年总收入,但这是以更长的工作时间为代价的。 相似文献
