A class of multipartner matching markets with a strong lattice structure

Summary. For a two-sided multipartner matching model where agents are given by path-independent choice functions and no quota restrictions, Blair [7] had shown that stable matchings always exist and form a lattice. However, the lattice operations were not simple and not distributive. Recently Alkan [3] showed that if one introduces quotas together with a monotonicity condition then the set of stable matchings is a distributive lattice under a natural definition of supremum and infimum for matchings. In this study we show that the quota restriction can be removed and replaced by a more general condition named cardinal monotonicity and all the structural properties derived in [3] still hold. In particular, although there are no exogenous quotas in the model there is endogenously a sort of quota; more precisely, each agent has the same number of partners in every stable matching. Stable matchings also have the polarity property (supremum with respect to one side is identical to infimum with respect to the other side) and a property we call {\it complementarity}.

Perceptional differences in the factors of local acceptance of spent nuclear fuel repositories

In the process of land use planning, massive social costs are incurred as various conflicts arise due to the location of locally unwanted land-use (LULU) such as spent nuclear fuel repositories. The factors affecting local acceptance of such facilities may vary according to individuals’ perceptional differences. This study aims to examine the differences in factors affecting local acceptance in regards to residents’ risk perception of spent nuclear fuel repositories. To do so, Q methodology was adopted. Three perceptional types—safety concerns-government distrust (type 1), safety trust-government trust (type 2), and safety concerns-conflict avoidance (type 3)—were identified and the differences in local acceptance factors among these types were verified via path analysis. The results showed that risk perception had the highest influence on local acceptance for types 1 and 3, whereas economic feasibility had the greatest influence for type 2. The methodology and results of this study may contribute to developing a policy on siting LULU facilities in consideration of local acceptance and the risk perception of residents.

Causes and consequences of psychological contracts among knowledge workers in the high technology and financial services industries

As organizations shift the central focus of their competitive strategy away from value appropriation towards value creation it is to knowledge workers that they will look to provide the innovation to fuel their continued development. The state of the relationship between the knowledge worker and the employer - the psychological contract - will determine whether this source of innovation and creativity is released. In this study, we developed and tested a causal model of the causes and consequences of psychological contract. Over four hundred participants who were knowledge employees drawn from eleven leading edge companies in the high-technology software, manufacturing and financial services sector participated in the study. We found support for the hypothesis that the psychological contract and those organizational processes relating to procedural justice would have a direct effect on two critical organizational outcomes, namely, employee commitment and intention to remain with the organization. We also found support for the hypothesis that psychological contract variables mediated the relationship between organizational processes and employee commitment and intention to stay with the organization.     

情商及其在企业管理中的路径依赖——以情绪资本为视角

情商是一种克服内心冲突、洞察人生价值、协调人际关系、提高生活质量的能力。情商理论是人类对自身智力认识的一个飞跃,在管理学领域,情商与工作绩效之间存在正相关。在企业管理中,充分培养、挖掘和运用建立在高情商基础之上的情绪资本,企业定能成就不平凡的事业。     

The investment development path of newly developed countries

According to foreign direct investment (FDI) path theory, developed countries are grouped into two phases, known as the fourth and fifth phases. Fourth‐phase countries (newly developed economies) show a technological and institutional “gap” in comparison with fifth‐phase economies, which explains their lesser capacity to generate direct investment. We found that these countries, which were less developed economies in the 1980s, had undergone a deep structural transformation. This transformation encouraged the multinationalization of firms, which is a differentiating element and one outcome of their development process. These results have clear policy implications: the governments of newly developed countries should take steps to increase the endowment of knowledge‐intensive assets. The main contribution of this paper is the theoretical reformulation of the fourth phase of the investment development path theory.     

Path Dependencies and the Long-term Effects of Routinized Marketing Decisions

The purpose of this paper is to discuss a simulation of marketing budgeting rules that is based on a simplified version of the market share attraction model. The budgeting rules are roughly equivalent to those that may be used in practice. The simulation illustrates the concept of path dependence in dynamic marketing systems and shows how it might result from decision rules potentially applied by marketers and retailers. Path dependence results from positive feedback in dynamic systems that imparts momentum to market choices. Where the potential for path dependence exists, there are implications for defining and measuring long-term effects of marketing decisions in a way that is meaningful to managers and researchers. In the simulations presented we show that limited retail assortments may contribute to path dependence when firms use either percentage-of-revenue rules or market learning experiments to set budgets. While other budgeting procedures (e.g., matching competition) may stabilize market share, this stability in the share dimension comes at the cost of instability for budgets and profits.     

中国—巴基斯坦自贸区贸易创造与贸易转移效应的实证分析

2007年7月1日,《中国—巴基斯坦自由贸易协定》正式实施,推动了中巴双方的经贸合作。文章运用巴拉萨模型检验了中国—巴基斯坦自由贸易区的贸易创造与贸易转移效应,根据实证的结果得出中巴自由贸易协定的实施,无论是对区内两国的贸易创造还是对区外国家的贸易转移效应都不明显,应利用中巴双方产品结构的互补性,促进双边贸易进一步增长。
