A one-sided many-to-many matching problem

This study discusses a one-sided many-to-many matching model wherein agents may not be divided into two disjoint sets. Moreover, each agent is allowed to have multiple partnerships in our model. We restrict our attention to the case where the preference of each agent is single-peaked over: (i) the total number of partnerships with all other agents, and (ii) the number of partnerships that the agent has with each of the other agents. We represent a matching as a multigraph, and characterize a matching that is stable and constrained efficient. Finally, we show that any direct mechanism for selecting a stable and constrained efficient matching is not strategy-proof.     

Habit Formation in an Overlapping Generations Model with Borrowing Constraints

We introduce habit‐formation in the three‐period OLG borrowing‐constrained framework of Constantinides et al. (2002) by allowing the utility of the middle‐aged (old) to depend on consumption when young (middle‐aged). This specification enables us to separate the effect of the two habit parameters (middle‐aged and old) since each representative age‐group can face different levels of habit persistence. The two‐habit setup underlines some important issues with regards to savings and security returns which do not always conform to the standard findings in the literature. In addition, the model produces equity premium consistent with US data for relatively small levels of risk aversion.     

Role of search for domain knowledge and architectural knowledge in alliance partner selection

Research Summary: The literature on technological alliances emphasizes that search for knowledge drives alliance formation. However, in conceptualizing technological knowledge, prior work on alliances has not made a distinction between domain knowledge—knowledge that firms possess in distinct technological domains—and architectural knowledge—knowledge that firms possess about how to combine elements from different technological domains. We argue that firms seek partners that are similar in domain knowledge to deepen their knowledge, and partners that are dissimilar in architectural knowledge to broaden their knowledge. Our results indicate that the likelihood of alliance formation increases when two firms are similar in domain knowledge and dissimilar in architectural knowledge. Further, our results show that these effects are positively moderated by the degree of decomposability of a firm's knowledge base. Managerial Summary: In dynamic environments, companies need to continually deepen and broaden their technological knowledge, and they often look for alliance partners who can provide them that knowledge. For knowledge deepening, companies are more likely to form alliances with those companies that have expertise in similar technological fields. For knowledge broadening, they are more likely to form alliances with those companies that have expertise in the same technological fields, but have different recipes for combining knowledge from those fields. Furthermore, a company with a modular knowledge base is more likely to seek a partner that has expertise in similar technological fields or whose recipes for combining knowledge from different technological fields are different from the recipes it has.     

徐家围子断陷区营城组火山岩识别

勘探实践表明徐家围子断陷营城组火山机构是深层天然气藏良好的储集体。本文以徐家围子断陷中部营城组火山岩为研究对象,该区火山岩厚度大,爆发相、喷溢相和火山沉积相等各种相带均较发育,通过对火山岩地震反射特征的系统分析,总结了各种相带的具体震相特征。并以此为依据,应用趋势面属性、相干体分析技术等多种手段,对火山机构的空间分布进行了识别与预测,在营城组共识别出44个火山锥,对本区火山岩气藏的勘探开发具有一定的指导作用。

金融发展与中国的经济增长——从储蓄动员型向市场配置的消费型经济转变

隐形税收机制瓦解后,储蓄动员型的金融发展模式取代了财政投资的主导地位,通过金融支持政策为公有经济部门融资,支撑了经济的高速增长。然而,随着市场约束机制的变化,金融支持政策的收益逐渐下降,成本却在递增。本文认为储蓄动员型的金融支持政策在一定阶段促进了经济的发展,但是也伴随着一系列经济发展的成本,比如降低了资本配置效率,过度投资产生的宏观经济成本和经济持续增长的外部风险加大等。因此,中国金融体制应深化改革,提高金融体系的资本配置效率,促进技术进步和生产效率的改进。同时,通过发展消费信贷和商业保险,减少信贷约束和不确定性,推动消费型经济的增长。     

高校财务风险的形成机理及防范机制分析

大量举债、资金运营以及学费拖欠等给高校财务管理带来极大风险。构建高校财务风险防范机制必须发挥政府主导作用,在加大教育经费投入的基础上规范高校办学规模;引导社会力量进入办学领域,在营造社会办学环境的基础上拓宽筹资渠道;建立现代大学制度,在规范管理的基础上强化内部监督;提高银行向高校贷款的门槛,在严格控制贷款规模的基础上落实还款渠道。     

合同的形式瑕疵及其补正——《合同法》第36条的解释与完善

我国《合同法》第36条应该解释为:法定或约定形式是合同的特别成立要件。合同的形式瑕疵可以因履行而补正,但《合同法》第36条对于合同义务的履行程度、形式瑕疵补正是否有溯及力以及继续性合同形式瑕疵补正的效力等问题缺乏完备的规定,对于约定形式的欠缺没有予以特殊处理。对此,应当予以完善。     

基于消费者认知的零售店铺印象形成过程拆解

基于消费者认知的零售店铺印象形成是解释消费者购买决策行为的重要内容,消费者对零售店铺印象的形成源于其对店铺重要属性的感知和三个认知参照标准:消费者以往的购物经历、零售店铺业态、店铺选址环境,这三个方面从不同的视角影响着消费者对零售店铺重要属性的判断和整体店铺印象的形成。本文在理顺以往学者研究结论的基础上,拆解并理顺了消费者零售店铺印象的形成过程。     

Interpartner legitimacy in regional strategic networks

Our aim is to add to the knowledge on a network level, focusing on if, and how, interpartner legitimacy affects the success or failure of network formation and development processes. Existing network theories and research tend to focus on resource exchange rather than on how actors perceive each other in terms of being legitimate or not. The purpose of the article is to analyze the interpartner legitimacy's influence on the formation and development processes of regional strategic networks (RSNs) from a network level. Two Swedish cases are discussed in terms of pragmatic, moral and cognitive interpartner legitimacy. The cases and the following discussion illuminate that interpartner legitimacy is important to incorporate into the analytical model if we wish to understand the processes of negotiations on the rules and norms which set the possibilities for survival of multi-actor interactions.
