"两岸共同市场":理念架构及其现实意义

2000年底以来,"两岸共同市场"已成为大陆与台湾政界、经济界、学术界共同关心和探讨的一个重要议题.随着中国国民党、亲民党、新党代表团相继访问大陆,两岸经贸合作问题更是引起了有关各方的高度重视.     

Optimal insurance in the presence of reinsurance

This paper studies an optimal insurance and reinsurance design problem among three agents: policyholder, insurer, and reinsurer. We assume that the preferences of the parties are given by distortion risk measures, which are equivalent to dual utilities. By maximizing the dual utility of the insurer and jointly solving the optimal insurance and reinsurance contracts, it is found that a layering insurance is optimal, with every layer being borne by one of the three agents. We also show that reinsurance encourages more insurance, and is welfare improving for the economy. Furthermore, it is optimal for the insurer to charge the maximum acceptable insurance premium to the policyholder. This paper also considers three other variants of the optimal insurance/reinsurance models. The first two variants impose a limit on the reinsurance premium so as to prevent insurer to reinsure all its risk. An optimal solution is still layering insurance, though the insurer will have to retain higher risk. Finally, we study the effect of competition by permitting the policyholder to insure its risk with an insurer, a reinsurer, or both. The competition from the reinsurer dampens the price at which an insurer could charge to the policyholder, although the optimal indemnities remain the same as the baseline model. The reinsurer will however not trade with the policyholder in this optimal solution.     

难舍老房子情结——访青岛房产置业集团总经理、党委书记姜岱积

2005年，青岛房产置业集团承诺利用3年时间，自筹资金4000万元，对市区70处125栋总建筑面积14万平方米的国有直管优秀历史建筑、名人故居和具有较高历史文化价值的建筑进行保护性修缮，使其重新焕发历史风采。如今，3年过去了，随着广西路37号（侯爵饭店旧址）、中山路1号（德国青岛俱乐部旧址）、沂水路11号（德国总督府旧址）等老房子修缮工作的完成，这一承诺也已经变成了现实。

基于电子鼻技术对调味品中非法添加罂粟壳的检测

采用便携式PEN3电子鼻检测调味品中非法添加罂粟壳。分别对非法添加有不同比例罂粟壳的花椒粉、孜然粉、烧烤粉进行辨别,用线性判别式(LDA)与多层感知器(MLP)两种方法对数据进行分析。结果表明:电子鼻能够较好的识别调味品中非法添加不同比例的罂粟壳,多层感知器相较于线性判别具有更好的区分效果,并且对未知样品进行准确预测。     

冲泡条件对辣木茶中稀土浸出率的影响研究

本文采用ICP-MS方法测定辣木茶的稀土总量,以及不同冲泡条件下稀土的浸出率。实验结果表明,辣木茶的稀土浸出率随冲泡时间的延长而升高,且增长逐渐趋于平缓。此外,随冲泡次数的增加,样品的稀土浸出率基本上呈减小趋势。五次冲泡后辣木茶中稀土的累计浸出率为18.15%。虽然原茶中稀土含量较高,但由于稀土氧化物主要残留于茶渣中,总体上处于比较低的暴露水平,对饮茶人群的健康影响较低。     

Brand Loyalty Versus Store Loyalty: Consumers’ Role in Determining Dependence Structure of Supplier–Retailer Dyads

Purpose: This article aims to integrate consumers into a channel dependence framework and explores the influence of consumers’ brand loyalty and store loyalty on the dependence structure within the supplier–retailer relationship. It also examines effects of the dependence structure on perceived conflict.

Methodology/approach: The authors test the proposed triadic relationship model among department store, supplier, and consumer by collecting matched data from both retailers and consumers in a Chinese retailing channel of sports and leisure apparel. Polynomial regression in conjunction with a response surface analysis (RSA) approach is used to test the hypotheses.

Findings: The results indicate that consumers’ brand loyalty positively affects retailer’s dependence on supplier, while consumers’ store loyalty positively affects supplier’s dependence on retailer. In addition, the retailer’s dependence is higher when consumers’ brand loyalty is higher than store loyalty; the supplier’s dependence is higher when consumers’ store loyalty is higher than brand loyalty; and the retailer’s dependence increases with the increase of both consumers’ brand and store loyalty when consumers’ brand and store loyalty are equal. Moreover, supplier’s dependence has a negative linear effect on retailer’s perceived conflict, whereas retailer’s dependence has an inverted U-shape effect on perceived conflict. A retailer would perceive more conflict when the retailer is relatively more dependent on the supplier; but the symmetrical interdependence has no significant effect on retailer perceived conflict.

Research implications: Researchers are encouraged to explore channel behaviors from a network perspective. Consumers, in particular, should be included in research frameworks related to channel dependence and behaviors. Suggestions for further research on the effects of dependence on the conflict are also proposed.

Originality/value/contribution: This study goes beyond the dyadic paradigm by integrating consumers into the framework of the channel dependence structure. It develops and tests a mechanism of consumers’ brand and store loyalty influencing dependence structure within a supplier–retailer dyad. It also enriches the literature of channel conflict by exploring the effects of retailer and supplier unilateral dependence on retailer perceived conflict with RSA methods.

Practical implications: The article provides several insightful implications for managers in understanding and managing interdependence structure in business-to-business marketing, especially in supplier–retailer relationships.     

Deterrence or Conflict Spiral Effect? Exercise of Coercive Power in Marketing Channels: Evidence from China

Purpose: The article aims to test the appropriateness of deterrence and conflict spiral models in marketing channels. Both models have been alternatively used as bases to explain firms’ power-related behaviors in marketing channels. However, the issue of the appropriateness of such an application in various contexts has not yet been addressed.

Methodology/approach: The authors develop the hypotheses based on deterrence theory and their alternatives based on conflict spiral theory. They gather data from 204 sales representatives of suppliers in China and use linear regression analysis to test their hypotheses versus alternatives.

Empirical findings: The data analysis offers supportive evidence for the deterrence logic but with unexpected results. By elaborating on the empirical results, the original assumption of deterrence theory, and the nature of interfirm relationship in marketing channels, the authors modify the deterrence model for research on power related-behaviors in the given context. The analysis implies a possible explanation for inconsistent findings in the literature regarding exercises of coercive power.

Originality/value/contribution: This article proposes a revised deterrence model that can interpret the empirical results with a consistent logic and better predict power-related behaviors in marketing channels.

Research limitations/implications: The research results may lack generalizability with respect to channel type and culture. It does not directly test the cognitive mechanisms that mediate the impact of power on its exercise. Researchers are encouraged to directly test the mediating constructs in other channels or countries.

Practical implications: The article includes some insights and implications for managers in understanding power structure and implementing influence strategies in business-to-business marketing.     

Inquiry and Review of Dependence in Marketing Channels: An Economics of Exchange Approach

This article extends the economics of exchange for bilateral monopolists to more general situations in marketing channels, that is, exchange between two members with alternatives, by incorporating insights drawn from power-dependence theory, interdependence theory, and the concept of switching cost. It proposes a framework of three factors of channel dependence and reviews the literature on the operationalizations of channel dependence based on the framework. This study concludes that the approaches used by channels researchers, explicitly or implicitly, more or less, capture the three factors of channel dependence. It also notices weaknesses in some approaches, including missing important aspects of a factor, possibilities of inflating or deflating channel dependence, and falling short of being a one-dimensional construct. The article finally draws conclusions and reports implications from the findings of this inquiry and literature review.
