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

作为东亚地区经济发展的核心,中日韩三国服务贸易的发展一直备受关注。日本服务贸易的竞争力水平是中日韩三国中最强的,其次是中国,最后是韩国。中国具有竞争力的行业主要是建筑、电信、计算机和信息以及其他商业服务,韩国具有竞争力的行业主要是旅游和建筑服务,日本具有竞争力的行业主要是运输、建筑、专业权利和特许服务以及政府服务。进一步对中日韩服务贸易的影响因素进行分析发现:人均国内生产总值、外商直接投资、货物贸易出口额和服务贸易开放水平与中日韩服务贸易竞争力水平都呈显著正相关关系,其中,服务贸易开放度水平对中日韩服务贸易竞争力水平的影响最大,外商直接投资对中日韩服务贸易竞争力水平的影响最小。 相似文献

采用国际市场占有率、显性比较优势指数及贸易互补性指数分析了中美两国纺织品在国际市场中的竞争地位及各纺织品类贸易互补性强度,并将美国发布的纺织行业技术通报(TBT)作为技术变量纳入随机前沿引力模型,进一步实证分析中美纺织品贸易的影响因素。结果表明:中国纺织品国际竞争优势强于美国,尤其表现在纺织制成品类;出口角度看,两国在纺织制成品类上呈现显著贸易互补性,进口角度看,两国在纺织原料上具有较强互补性。在影响因素中,技术壁垒、进口国经济、出口国人口及两国距离负向抑制中美纺织品贸易,出口国经济、进口国人口及人均收入之差正向促进中美纺织贸易发展。 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

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

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

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

This paper explores the role of trade integration—or openness—for monetary policy transmission in a medium-scale new Keynesian model. Allowing for strategic complementarities in price setting, we highlight a new dimension of the exchange rate channel by which monetary policy directly impacts domestic inflation: a monetary contraction which appreciates the exchange rate lowers the local currency price of imported goods; this, in turn, induces domestic producers to lower their prices too. We pin down key parameters of the model by matching impulse responses obtained from a vector autoregression on time series for the US relative to the euro area. Our estimation procedure yields plausible parameter values and suggests a strong role for strategic complementarities. Counterfactual simulations show that openness alters monetary transmission significantly. While the contractionary effect of a monetary policy shock on inflation and output tends to increase in openness, we find that monetary policy's control over inflation increases, as the output decline which is necessary to bring about a given reduction of inflation is smaller in more open economies. 相似文献
