We use line integral theory to lay out in a more general theoretical framework the conditions under which it is possible to measure with market data the welfare effects of a change in a nonmarket good. We present in detail a numerical method of measuring the value of nonmarket goods using market data, under either weak neutrality or weak complementarity. Our numerical method is more flexible than the existing analytical method because it can be used with any well-behaved Marshallian demand function, and can be used even when the willig condition does not hold.  相似文献

中韩自由贸易区的可行性与障碍分析   总被引:2,自引:0,他引:2  
中韩自由贸易区作为推动中日韩乃至整个东亚地区经济合作的有效途径,它的建立十分重要.在建立中韩自由贸易区是必要的这一前提下,从中韩政界和企业界的态度、经贸文化交流、经济互补性和建立后的贸易效应四方面论证建立中韩自由贸易区是可行的;同时,指出建立中韩自由贸易区的障碍并提出了相应的对策.  相似文献

知识表达、知识互补性、知识产权均衡   总被引:16,自引:0,他引:16  
基于知识的“代数格”表达方式和知识的互补性原理 ,这篇文章讨论知识产权的博弈均衡问题。每个人都拥有“局部知识” ,显然 ,如果法律对每个人的局部知识设立产权并由政府全面加以保护的话 ,人类知识将无法获得任何发展。另一方面 ,如果法律不承认任何知识的产权且政府对任何知识产权都不加以保护的话 ,人类知识也难以获得发展的激励。这里将证明 ,N个具有局部知识的社会成员在社会整体知识构成的代数格上关于各自的“局部知识”的价格的博弈存在至少一个纳什均衡———此即该社会内部自恰的和最优的知识产权配置。由周林 ( 1 994) ,这类均衡点构成一完备格。又由MilgromandShannon( 1 994) ,博弈的每一参与者最佳对应集内的最大策略和最小策略在社会知识的代数格上 (按集合强序 )单调非减 ,这意味着当社会成员的初始知识水平有所提高时 ,由产权博弈均衡所决定的各个局部知识的知识产权价格将相应有所上升。所有上述结果都不需要通常的凸性假设 ,因此在以“知识”为核心要素的经济分析中 (包括收益递增经济学 )具有独特重要的意义  相似文献

文章在对场景理论进行回顾的基础上,确立了场景化架构的三要素:空间、产品和消费者,刻画了场景化架构的架构属性:空间的审美性、产品作为场景文化价值载体的媒介性、消费者对场景传达的文化价值的认同性,构建了场景化架构零售商业模式的理论模型。实证研究表明场景化架构理论模型各变量具有很好的聚合效度和区别效度,也验证了新颖性和互补性在场景化架构对体验价值创造影响的中介作用。文章的主要贡献在于提出了场景化架构这一构念,并构建了场景化架构零售商业模式的理论模型,探索和验证了该商业模式实现价值创造的内在机理,同时验证了在以往实证研究中对商业模式价值属性讨论极少的互补性是一个重要的中介变量。  相似文献

Ronald Jones made seminal contributions to general‐equilibrium theory, moving away from an emphasis on the existence of equilibrium to algebraic formulations which enabled us to characterize key relationships between parameters and variables, such as that between tariffs and domestic factor prices and welfare. But the analysis remained limited in value for policy evaluation: the analysis was local, it provided only qualitative results, it was limited to very small models, and strictly interior solutions had to be assumed. The contribution of this paper is largely pedagogic and methodological. I show how the tools and approach pioneered by Jones can be generalized via the use of duality, complementarity and the Karush–Kuhn–Tucker theorem into a global, quantitative analysis of large changes in high‐dimensional models which also allows for regime changes and corner solutions. I then show how the resulting nonlinear complementarity problem directly translates into a numerical model using the General Algebraic Modeling System (GAMS).  相似文献

In this paper, we examine the match between resource relatedness and post-merger integration on technology innovation of acquiring firms to find the rationale behind technology-sourcing cross-border mergers and acquisitions (M&As) of Chinese multinational enterprises. Using a sample of 88 Chinese technology-sourcing cross-border M&As, we find that the acquirer will improve technology innovation when greater resource similarity between the acquirer and target firms is matched with a high integration degree and a low target autonomy level. Meanwhile, the acquirer can improve technology innovation when greater resource complementarity is matched with a low level of integration degree in technology-sourcing cross-border M&As. This paper provides the acquiring firms with fresh ideas of how to make the integration decisions of technology-sourcing overseas M&As. We hope to help multinational enterprises to achieve more outstanding technology innovation performance through technology-sourcing overseas M&As in an intense global competitive environment.  相似文献

In this paper we study the effectiveness of different types of cohesion policies with respect to convergence of regions. A two-region agent-based macroeconomic model is used to analyze short-, medium- and long-term effects of policies improving human capital and fostering adoption of technologies in lagging regions. With fully integrated labor markets the human capital policy positively affects the economically stronger region but reduces production in the targeted weaker region. Subsidies for high technology investment in the weaker region have a positive local output effect and a negative effect on the neighboring region, thereby fostering convergence. When labor markets are not integrated both policies support convergence.  相似文献

Various government laws have recently been enacted to alleviate the environmental deterioration of transportation systems. Environmental constraint is a valid means to explicitly reflect various environmental protection requirements imposed by the government. In this paper, we examine the environmentally constrained traffic equilibrium problem (EC-TEP), which is a fundamental tool for modeling and evaluating environmental protection requirements. Specifically, we provide an equivalent reformulation for the EC-TEP. The proposed reformulation adapts the concept of gap function to simultaneously reformulate the nonlinear complementarity conditions associated with the generalized user equilibrium conditions, environmental constraints, and conservation constraints as an equivalent unconstrained optimization problem. This gap function reformulation has two desirable features: (1) it can handle a general environmental constraint structure (linear or nonlinear; link-based or area-based) and a general link and route cost structure, enhancing the modeling adaptability and flexibility; (2) it is smooth and unconstrained, permitting a number of existing efficient algorithms for its solution. A gradient-based solution algorithm with a self-regulated averaging stepsize scheme is customized to solve the reformulated unconstrained optimization problem. Numerical examples are also provided to demonstrate the modeling flexibility of the proposed EC-TEP reformulation.  相似文献

从世界银行企业投资调查数据中可以发现,中国出口企业内部的工资差距高于非出口企业.由于处在生产技术结构与所在地区比较优势更为接近的行业中的企业,在没有保护和补贴的情况下具有自生能力,能够获得较高的剩余,所以这类企业在开放竞争的条件下资本积累速度更快,在资本技术互补的假设下,增加了对更高技能劳动力的需求.出口对企业内高级管...  相似文献
