中国住宅投资引领经济增长吗?

本文运用1985—2009年中国各省、直辖市、自治区的数据,对住宅投资与经济增长之间的领先—滞后关系进行分析。结果表明,无论是1985—2009年全时段还是以1998年大规模房改为分界线的分时段,无论是全国各省市还是分区域的各省市面板数据,经济增长引领住宅投资的单向Granger因果关系是稳定的;不同于一些研究和政策措施所主张的住宅投资引领经济增长的观点,本文认为找不到证据来支持住宅投资带动经济增长的论点。由此可见,所谓"住宅引领增长假说"在我国并不成立,而我国自上世纪90年代中期以来一直大力促进住宅投资以带动经济增长、把住宅建设当作国民经济的新增长点和支柱产业的政策值得反思。     

Evolutionary stability and lexicographic preferences

We explore the interaction between evolutionary stability and lexicographic preferences. To do so, we define a limit Nash equilibrium for a lexicographic game as the limit of Nash equilibria of nearby games with continuous preferences. Nash equilibria of lexicographic games are limit Nash equilibria, but not conversely. Modified evolutionarily stable strategies (Binmore and Samuelson, 1992. J. Econ. Theory 57, 278–305) are limit Nash equilibria. Modified evolutionary stability differs from “lexicographic evolutionarily stability” (defined by extending the common characterization of evolutionary stability to lexicographic preferences) in the order in which limits in the payoff space and the space of invasion barriers are taken.     

Have Employment Relationships in the United States Become Less Stable?

There has been considerable debate as to whether job stability has declined in the United States. This paper uses data from the Survey of Income and Program Participation (SIPP) to examine the incidence of labor market turnover between 1986 and 1993. Specifically, we calculate one- and two-year separation rates and then analyze turnover by the source of separation. We find that the incidence of job separations did not increase over the period under investigation, but appears to have declined somewhat. When analyzing separations by reason, conditional on separating from an employer, we find little evidence of temporal changes in the composition of turnover that would indicate greater employment instability. Therefore, we do not find conclusive evidence that employment relationships have become more unstable in the recent past.      

Candidate stability and nonbinary social choice

Summary. The requirement that a voting procedure be immune to the strategic withdrawal of a candidate for election can be formalized in different ways. Dutta, Jackson, and Le Breton (Econometrica, 2001) have recently shown that two formalizations of this candidate stability property are incompatible with some other desirable properties of voting procedures. This article shows that Grether and Plott's nonbinary generalization of Arrow's Theorem can be used to provide simple proofs of two of their impossibility theorems.

Testing the conflict-performance assumption in business-to-business relationships

There is little empirical research published testing the interdependency between conflict in business-to-business relationships and commercial performance. The “conflict-performance assumption”—all other factors being equal, relationships where conflict is low will outperform relationships where conflict levels are higher—remains central in the marketing channels' literature despite insufficient and contradictory empirical evidence. There are several explanations for the lack of a clear relationship between conflict and performance. Rosenbloom [J. Mark. 37 (1973) 26] theorises that the relationship between conflict and channel performance follows an inverted U-shaped curve, where conflict is most productive at moderate levels and least productive at very low or high levels. Others have argued for a simpler, linear relationship between conflict and performance, usually negative in nature. Various theories about the conflict-performance relationship are empirically tested in a large marketing channel, using a number of dyadic and monadic measures of conflict (latent, perceived, and affective) and two objective measures of performance (effectiveness and efficiency). A linear model (performance declining as conflict increases) is adequate to explain the relationship between dyadic measures of both perceived and affective conflict and channel effectiveness. A threshold model is found to be superior to a linear model in explaining the relationship between dyadic measures of perceived and affective conflict and efficiency. Conflict increases slowly as efficiency falls until a threshold is reached when conflict escalates. Practical implications include that companies need to consider whether performance criteria affecting efficiency are as important to their business partners as those affecting effectiveness. If they are not, then business partners should be rewarded for meeting any such criteria that are more important to the one side of a relationship dyad than to the other.     

The coexistence of transaction and relational marketing: Insights from the Chinese business context

Transaction and relational approaches to marketing have been promoted as alternative forms but recent evidence suggests that they may coexist. We explore this in the context of China. If firms operating in a highly relational society, such as China, exhibit transactional behavior, these two approaches must be compatible. We argue that Chinese values give rise to business practices consistent with both transactional and relational perspectives. These are summarized in six propositions for research. Theory building and managerial practice could benefit from thinking in terms of how elements from the two perspectives can be brought together rather than remain as alternatives.     

Organizational resources enabling service responsiveness: Evidence from Greece

This article examines the implementation of relationship marketing strategy based on a sample of business-to-business firms operating in Greece. Organizational resources, including a focus on learning and flexibility/adaptation in strategic planning, are demonstrated to be antecedents of effective relationship marketing strategies. The possession of these resources lead to superior customer performance (as measured by customer satisfaction and loyalty) and, ultimately, superior financial performance (as measured by profit levels, profit margin, and ROI). Our results provide support for the development of organizational resources that foster and enable relationship marketing in business-to-business environments since such resources are linked with improved firm performance.

Determinants of economic and social satisfaction in manufacturer-distributor relationships

The aim of this work is to examine the dimensions of satisfaction in manufacturer-distributor relationships as well as identifying the antecedents of both the economic and the non-economic dimensions of satisfaction. A literature review about satisfaction in marketing channels is followed by quantitative research into how this interchange process is perceived by food product distributors in their relationships with manufacturers. The results provide strong support for the impact of communication, trust and commitment on satisfaction, as well as the interrelationships among the economic and the non-economic dimensions of satisfaction. Theoretical and managerial implications are extracted from these findings.     

Relationship equity and switching behavior in the adoption of new telecommunication services

This paper first defines and then presents a model of “relationship equity” for business markets. It points out that the potential benefits of managing relationship equity have been largely ignored and that a general model and stream of relevant research questions could be useful to marketing and relationship practitioners. The model developed considers the special case of key account management as antecedent, two different types of moderator variables, relationship equity as a perception by the buyer, and switching behavior via adoption of new telecommunication services as a result of this perception. The model is used as a basis for developing a number of working propositions.
