商业信用与企业规模的负相关关系——基于关系网络的理论分析与实证检验

企业所提供的商业信用规模和企业规模之间的关系,在发达国家和发展中国家表现迥异,发达国家是正相关关系,而发展中国家是负相关关系。企业规模、关系网络和商业信用三者之间的关系是造成这一差异的主要原因。     

老年人养老方式选择的影响因素研究——基于CHARLS数据的实证分析

本研究在CHARLS调查所获得的微观数据的基础上进行,首先对老年人养老方式选择的结果和老年人人口特质、健康状况、经济状况等方面的6个变量进行关联分析,再通过二项Logistic回归模型,将是否选择机构养老作为被解释变量进行回归分析。结果表明非机构养老方式仍是老年人的主要选择,年龄、婚姻状况、慢性疾病情况、经济状况等因素与老年人养老方式的选择存在显著的关联并对选择结果产生影响。

危机时刻的社会保障支出

文章研究了社会保障支出与金融危机之间的关系,回答了两个问题:第一个问题是:在金融危机发生后,社会保障支出的发展趋势如何?第二个问题是:哪些原因可以解释这些变化?文章认为,社会保障制度往往诞生于危机之际。此外,一般地讲,社会保障支出在危机期间会增加;但是各国情况不同,发达国家显示出反周期支出的特点。文章支持这样一个观点,即危机可以被当作改善和加强社会保障的机会,而在这样的过程中,各国不仅可以缓解危机最不利的影响,而且能制定比较好的社会政策,改进长期危机的防范应对。     

Social aspirations in European banks: peer-influenced risk behaviour

We test a sample of 3,586 banks from 33 European countries to determine whether performances above or below a social aspiration level (median performance of peer banks) influence banks’ aggregate risk levels. Our results are consistent with the behavioural theory of the firm and prospect theory in that we find that bank performance below a bank’s social aspiration level is followed by increased aggregate risk, i.e. risk-taking behaviour in the subsequent year. Although under-performing banks tend to be risk-takers, large banks and banks with high aggregate risk levels tend to limit the increase in their aggregate risk levels.     

国内“创新驿站评价”研究述评

回顾了国内创新驿站评价相关研究,将其归纳为创新驿站演进动因评价、治理机制评价、绩效评价、站点建设评价四个方面。评价研究表明:外生约束条件下的适应性以及内生支撑条件下的驱动性是评价创新驿站形成动因的逻辑主线,而组织结构、运行机制及外部治理因素是影响创新驿站治理的主要因素;创新驿站绩效评价关注于定性的功能效用评价和定量的作用效果评价;中国创新驿站站点的实践为理论认识增添了直接现实性。     

旅行社产品质量网络评价系统设计研究

依据绩效感知服务质量度量模型(SERVPERF)以旅游者的旅游知觉为标准对旅行社产品进行评价。评价系统将旅行社产品细化并以旅游产品消费过程为基础,以官方机构为主体,运用网络认证码为保障确保结果的真实性。旨在为旅行社产品质量评价、监督提供可行、可靠的网络评价系统。通过评价使旅游信息更加对称,并对旅行社产品质量改进起到督促作用,对实现旅游企业间的良性竞争具有重要的现实意义。     

Cost effectiveness of rosuvastatin in patients at risk of cardiovascular disease based on findings from the JUPITER trial

Abstract

Objective:

This study assessed the long-term cost effectiveness of rosuvastatin therapy compared with placebo in reducing the incidence of major cardiovascular (CVD) events and mortality.

Methods:

A probabilistic Monte Carlo simulation model estimated long-term cost effectiveness of rosuvastatin therapy (20?mg daily) for the prevention of CVD mortality and morbidity. The model included three stages: (1) CVD prevention simulating the 4 years of the JUPITER trial, (2) initial CVD prevention beyond the trial, and (3) subsequent CVD event prevention. A US payer perspective was assessed reflecting direct medical costs, and up to a lifetime horizon. Sensitivity analyses tested the robustness of the model estimates.

Results:

For a hypothetical cohort of 100,000 patients at moderate and high risk of CVD events based on Framingham risk of ≥10%, estimated quality-adjusted life-years (QALYs) gained with rosuvastatin therapy compared with placebo was 33,480 over a lifetime horizon, and 25,380 and 9916 over 20-year and 10-year horizons, respectively. Approximately 12,073 events were avoided over the lifetime; 6,146 non-fatal MIs, 2905 non-fatal strokes, and 4030 CVD deaths avoided. Estimated incremental cost-effectiveness ratio (ICER) for cost per QALY was $7062 (lifetime), $10,743 (20-year horizon), and $44,466 (10-year horizon). For a hypothetical cohort similar to the overall JUPITER population, the cost per QALY ICER was $11,025 for the lifetime and $60,112 for a 10-year horizon.

Limitations:

The cost-effectiveness comparison of rosuvastatin 20?mg was against no active treatment (as opposed to an alternative statin) due to lack of comparative cardiovascular morbidity and mortality risk reduction data for other statins in a population similar to the JUPITER trial population. The analysis was conducted from the payer perspective and lack of inclusion of indirect costs limit interpretability of results from a societal perspective.

Conclusions:

Treatment with rosuvastatin 20?mg daily, is a cost-effective treatment alternative to no treatment in patients at a higher risk (Framingham risk ≥10%) of CVD.     

政府支出与私人消费的关系研究——基于跨国数据(1983-2008年)的面板协整分析

文章运用面板协整分析方法和世界上36个国家(20个发达国家和16个发展中国家)1983-2008年的面板数据进行跨国研究,通过建立变系数面板模型并结合可支配收入和宏观经济环境的影响,分析了政府支出和私人消费的关系。研究结果显示,总体上而言,样本国家的政府消费支出与私人消费成互补关系,可支配收入仍然是影响私人消费的主要因素,宏观经济环境(经济开放程度和失业率)对消费的影响在统计上很不显著。为了扩大消费,中国政府应实施积极的财政政策、扩大财政支出和提高社会保障水平以及切实解决民生基本难题。     

Does different NPD project’s characteristics lead to the establishment of different NPD networks? A knowledge perspective

In today’s highly competitive and globalised marketplace, firms need more and more to develop new knowledge and capabilities to leave behind their competitors, thus gaining market share. Knowledge is fundamental for success because a firm that knows more, often develops more sustainable competitive advantage. Networks, like those oriented to New Product Development, seem to be valuable means of learning, as firms could not achieve alone the same results, or at least not as quickly. Through this integrative systematic review, we are interested in understanding whether different New Product Development projects correspond to different New Product Development networks in terms of knowledge exchanged among the partners involved. Our results highlight the presence of four types of New Product Development networks deriving from the combination of the degree of innovation characterising the project and its mode of development. Implications and future research are also proposed.
