价值运筹——价值工程在世※界经济新运行形态下的发展

认知世界经济的巨大变化需要新的观念,人类经济总体发展模型又称“四方式二形态”假说,可以作为研究经济和管理问题的基本框架和准则。由此得出当前世界经济按功能经济形态运行。列出了一些与物质经济运行形态不同的主要的新特征。总结出六条关于功能价值的基本原理,以供处理有关问题之用。给出了“价值运筹”的定义,指出价值运筹的实质是“智能经营”,因此“全员价值运筹”是必然的选择。它将推动企业管理创新     

Efficient rank tests for semiparametric competing risk models

We consider a semiparametric competing risk model given by k independent survival times. The paper offers an asymptotic treatment of tests for the semiparametric null hypothesis of equality of the underlying risks. It turns out that modified rank tests are asymptotically efficient for certain semiparametric submodels, where the baseline hazard is a nuisance parameter. In addition, the asymptotic relative efficiency of the present tests is derived. A comparison of asymptotic power functions can then be used to classify various tests proposed earlier in the literature. For instance a chi-square type test is efficient for proportional hazards. Data driven tests of likelihood ratio type are proposed for cones of alternatives. We will consider certain stochastically increasing alternatives as a special example. The paper shows how the concept of local asymptotic normality of Le Cam works for hazard oriented models.     

The impact of low-cost carriers on airport choice in the US: A case study of the Washington–Baltimore region

Previous research has shown that low-cost carriers (LCCs) may stimulate traffic at an airport by offering low fares. Using passenger survey data from the Washington–Baltimore region’s three airports, we find that the benefits of LCCs to airports extend beyond the traffic generated directly by the LCCs through their low fares. In addition, we find that the mere presence of an LCC at an airport can attract passengers, even to competing carriers. These “halo effects” from LCC presence increase the significance to airport managers of attracting LCCs in order to generate passenger demand.     

生态消费模式:社会主义生态文明建设的必然选择

当前,我国消费伴随着经济的快速发展日益被异化为"病态式消费"模式,这使国民经济的协调发展遭到了严重破坏,甚至生态系统也面临着崩溃的危险。我国新富群体缺乏正确的消费观念,加上西方消费主义影响,引发了诸多的社会问题。实践证明,只有树立正确的消费观念、克制消费欲望、调整消费行为,才能建立生态消费模式,才能符合社会主义生态文明的要求,实现人与自然的协调发展。     

The Responsiveness of Households to Energy Demand Management Initiatives: Segmenting by Household Types

Segmentation is often a complex and costly process, which commonly involves identifying groups with differing attitudes and behaviors or demographics. However, the segments generated may not adequately explain differences between consumers, or it can be difficult to identify households for target marketing, which consequently makes it difficult to use segmentation in practice. In this paper we present segmentation by household type as a simple method of segmentation, accessible to nonprofit organizations with limited resources and able to be employed using a secondary data set or with relatively simple data collection and analysis. Despite its simplicity, our findings show that this form of segmentation differentiates well between segments in terms of their actual electricity use, their past efficiency behaviors and preferences for efficiency programs. The results of focus groups and a survey of 4,000 households reveal, among other things, the effect of having children and of marital status on energy use and efficiency behaviors, the high curtailment but low investment behaviors of single parent households, and the low efficiency behaviors of shared households.     

Investigating the impact of surprise rewards on consumer responses

Adopting an experimental approach, this research compared surprise rewards with membership discount rewards in terms of their impact on customer responses of delight, frustration and satisfaction. In addition, this research examined the circumstances under which surprise rewards should be offered in order to yield maximum benefits for hospitality firms. In particular, the study examined how the customer's cumulative satisfaction (high vs. low) influences the effectiveness of surprise rewards (vs. membership discount rewards) in increasing customer delight and satisfaction and decreasing customer frustration. Consistent with the theoretical predictions, results show that surprise rewards are more effective than membership discount rewards for enhancing customer delight and satisfaction and attenuating customer frustration, particularly when the customer's cumulative satisfaction is low. These findings have important implications for the hospitality industry. Hospitality managers and marketers could use this information to design effective loyalty reward programs.     

对于劳动力市场的性别歧视的实证分析——以美国的2007年劳动力市场的数据为例

通过借鉴美国2007年美国劳动力市场的数据,对于劳动力市场中的性别歧视现象作了实证分析。考虑到了影响工资收入的职业类型、技术差异,劳动者偏好等影响因素对于劳动群里女性比例与该劳动群体里的工资收入进行了多元回归分析。该研究结果对于改善较不成熟的中国劳动力市场的就业问题具有一定的借鉴意义。
