21世纪中国学界辽金经济史研究回顾与展望

辽金经济史一直是学者研究的重点,21世纪以来学界在辽金农业概况、发展原因、土地制度,畜牧业结构,货币种类、税收制度及贸易几个方面研究深入,取得了丰硕的成果。但对区域农业特点、土地买卖及粮食供给、辽金农业思想史等问题缺乏深入研究。     

Fair Trade Certification: The Case of Tea Plantation Workers in India

This article analyses the impact of Fair Trade certification by focusing on its interactions with the patron–client relations traditionally established between management and workers in tea plantations in India. It argues that the invisibility of Fair Trade among workers, which generally reinforces existing patron–client relations through Fair Trade premiums, inversely hides the patronage of the management, and that workers are empowered when a premium is invested in a community development project led by an independent third‐party organisation.     

浙江非公企业劳资矛盾与工会调节作用研究——基于农民工租住地工会的实证研究

随着社会经济的发展,非公有制经济对我国经济的贡献越来越大,非公有制企业的劳资关系问题也日益突出.今天的中国,尽管工会面临着种种困境,但工会的作用仍然很重要.当前迫切需要解决的是工会代表工人利益的有效性问题.农民工租住地工会通过组建工会的方式吸纳农民工精英进入工会管理层,并动员农民工参与社区的公共生活,逐渐使他们产生了“社区认同”,农民工管理发生了由社会被动防控与管理型向主动引导、服务、建设型的转变,由分割向融合的转变,破解工会在农民工集聚的地方如何组织管理与协调劳资矛盾,促成了社区的和谐与稳定.探讨市场经济条件下企业外工会力量的成长或许能为中国工会转型提供一些借鉴和帮助,为转型期创新社会管理提供有益探索.     

埃及过渡政府的外交政策之调整

埃及过渡政府成立以来,已在外交政策方面做出多方面调整:对中东和周边的以色列、伊朗、尼罗河流域国家等,过渡政府的外交政策调整以转向和改变为主,且调整幅度较大;对以美国为首的欧美大国,采取了延续基础上的调整；对包括中国在内的传统友好国家,则继续维持与深化与这些国家的关系.过渡政府对外交政策作出调整的原因主要包括:国内群众的诉求、重塑阿拉伯世界的领导形象以及革命后埃及“本土化”意识的兴起.埃及在外交方面的调整涉及美国、伊朗、以色列、海湾国家、非洲各国等,无疑对地区安全与合作产生了重要影响.     

加入WTO与中国社会保障制度的发展与完善

十年来中国社会保障建设取得了很大的成就,社会保障成为改善民生和社会建设重要领域和促进力量,对于克服经济全球化深入发展背景下各种矛盾、促进经济发展和社会稳定发挥着积极的作用。但是,中国社会保障制度还不完善,面对世界贸易组织框架下越来越复杂的国际国内形势,需要进一步加快社会保障制度建设,选择科学合理的社会保障模式和管理体制,加强社会保障公共服务体系建设,实现人人享有社会保障。     

埃及“7·3”事件后美国对埃援助政策研究

埃及被认为是美国在中东地区和阿拉伯世界最坚定的盟友。美国自1979年埃及与以色列签署和平协议以来，每年向埃及提供大量的军事与经济援助。2013年7月3日，埃及民选总统穆罕默德·穆尔西被埃及军队废黜。根据联邦法律，美国暂停对埃及的部分援助。本文从“7·3”事件后美国对埃及援助的变化及其特点、影响援助变化的主要原因进行分析，展现美国对埃及援助政策中的复杂利益和战略考量，根据对历史与现实的分析，预测美国今后对埃援助政策的走势。     

Generalized correlation and kernel causality with applications in development economics

New generalized correlation measures of 2012, GMC(Y|X), use Kernel regressions to overcome the linearity of Pearson's correlation coefficients. A new matrix of generalized correlation coefficients is such that when |r*_ij| > |r*_ji|, it is more likely that the column variable X_j is what Granger called the “instantaneous cause” or what we call “kernel cause” of the row variable X_i. New partial correlations ameliorate confounding. Various examples and simulations support robustness of new causality. We include bootstrap inference, robustness checks based on the dependence between regressor and error, and on the out-of-sample forecasts. Data for 198 countries on nine development variables support growth policy over redistribution and Deaton's criticism of foreign aid. Potential applications include Big Data, since our R code is available in the online supplementary material.     

Coordinating contracts for a financially constrained supply chain

We consider a financially constrained supply chain in which a supplier (leader) sells products to a retailer (follower) who has no access to bank financing due to her low credit rating. However, the supplier can borrow from a bank and offer trade credit to the retailer to alleviate her financial constraint. Failure to pay off a bank loan or trade credit incurs a variable default cost. We analyze the centralized version of the supply chain to obtain new coordination requirements. We then examine whether revenue-sharing, buyback, and all-unit quantity discount contracts can coordinate our supply chain. We show that the all-unit quantity discount contract fails to coordinate. However, the revenue-sharing and buyback contracts can coordinate the supply chain, but only when the supply chain has a sufficient total working capital. Moreover, they cannot allocate profit flexibly unless the supplier has a large enough working capital. Finally, we design a generalized revenue-sharing contract that coordinates the supply chain with flexible profit allocation, and also show by numerical examples its superiority over the revenue-sharing and buyback contracts.     

欧盟区域经济一体化的投资效应研究

区域经济一体化是当今世界经济发展的一个重要特征,一体化发展的程度和范围正日益突破仅以贸易自由化为主的浅度一体化,向包括投资政策等更广泛政策的深度一体化发展。区域经济一体化发展对区域内国际直接投资(FDI)的流入是否产生了预期的促进效应,这种效应的发生又与哪些因素密切相关?从跨国公司的投资动机出发,对欧盟1996-2006年面板数据的分析发现,区域经济一体化发展对FDI流入有显著促进作用,成员国的经济发展水平、服务业发展水平等经济初始禀赋条件对投资效应有显著影响。我国在制定参与区域经济合作的相关措施时可以从中得到一些有益的启示。     

局部均衡函数及其构造

研究了局部均衡函数,定义了改进的局部变权向量,提出了与之对应的状态局部变权向量和局部均衡函数,证明了两类函数是局部均衡函数;利用局部变权向量建立了企业信用评估模型,并通过实例说明了该理论是有效的和合理的.
