我国目前的市场结构具有典型的分散竞争型特征,这种市场结构制约了规模经济的实现,不利于企业的技术创新,也不能适应经济全球化条件下激烈的国际竞争需要.因此,我国应充分利用跨国公司对我国的投资,改善我国的市场结构,提升我国产业的国际竞争力,参与全球范围的垄断性竞争. 相似文献

This paper constructs a general equilibrium model in a world with two-symmetric countries. It explains welfare gains from international trade and horizontal Foreign Direct Investment (FDI) in the economy with firm heterogeneity and variable markups stemming from oligopolistic competition. My model shows that the pro-competitive effects of trade and horizontal FDI happen because trade openness induces an increase in product market competition that reduces markups and toughens selection, increasing aggregate productivity. The most significant contribution of the paper is that multinational firms, via horizontal FDI, produce the most significant welfare gains through the toughest selection and lowest markups. 相似文献

In this article, we present a two‐period model in which one firm operates in two markets: a monopoly and a duopoly. Assuming that this firm has private information on the cross‐price elasticity of demand between the products sold in both markets, it limits its quantity supplied in the monopoly market in order to make its rival in the other market believe that entry into the monopolized market is unprofitable. As a result of this strategy, the average prices observed in both markets increase. This result suggests that the detrimental effects of entry deterrence on consumers' welfare are stronger than those predicted by previous literature. 相似文献

We examine a quantity competition among branded and nonbranded firms. The market comprises two consumer segments: one purchases only branded products (the high-end market), while the other segment's consumers purchase less expensive products (the low-end market). When branded firms take actions sequentially, we show that the branded leader has an incentive to restrict its quantity to avoid entering the low-end market. As the follower recognizes this incentive, it can restrict the leader by implementing a quantity constraint, which is affected by the number of nonbranded firms. We find that both the branded leader and follower could benefit from the nonbranded firms and that the leader prefers to have more nonbranded firms in the market than the follower does. Furthermore, we show that the free entry of nonbranded firms could negatively affect total surplus as well as consumer surplus even without any costs, because of the premium pricing of branded products. 相似文献

We investigate the effects of free trade agreements (FTAs) on tariffs and welfare in vertical trade. We consider a three-country model, where an FTA is formed between a country exporting a final good and a country exporting an intermediate good. The FTA unambiguously leads to a reduction in the member country’s tariff, but may cause the non-member country’s tariff level to increase. In the case, where FTA raises the non-member country’s tariff level, the FTA increases that country’s welfare. In contrast, the FTA may render its member countries better off. This result implies that the formation of an FTA may not always be Pareto-improving. 相似文献

This study constructs a game of technology selection and Bertrand-like price competition in a market with free entry. It demonstrates the existence of a Nash equilibrium in which a small number of firms adopting a large-scale technology coexist with, and charge a lower price than, a large number of firms adopting a small-scale technology. In this equilibrium, both available technologies and resources are allocated efficiently. This result provides a new economic rationale for antitrust law in general and, in particular, the US Sherman Act, wchich regards free entry and price competition as of foremost importance for maintaining market quality. 相似文献

We show that the long-term properties of price and cost in Chamberlin's monopolistic competition model can be reproduced with a soft capacity constrained price competition oligopoly model for a homogeneous good with free entry. 相似文献

This paper analyzes market diffusion in the presence of oligopolistic interaction among firms. Market demand is positively related to past market size because of consumer learning, networks, and bandwagon effects. Firms enter the market freely in each period with fixed costs and compete in quantities. We demonstrate that the nature of the inefficiency under free entry can change as the market grows, and more importantly, that S-shaped diffusion can be a signal that the number of firms under free entry is initially insufficient, but eventually excessive. 相似文献

根据政府对金融业的干预程度,存在四种不同的控制策略:市场约束、法院诉讼、管制实施、国家所有。选择何种方式最有效取决于金融制度可能性边界(IPF)的形状,即依赖于各国金融部门的特定状况。这又包括三个层面:一是与整个经济金融环境相联系层面上的金融业管制与竞争关系;二是产业层面相联系的金融业管制与竞争关系;三是单个金融机构层面上的管制与竞争关系。这三种层面是相互联系,共同构成一国金融业管制与竞争的蓝图,并决定了一国的金融管制效率。根据中国金融业的实际情况,指出中国金融业管制与竞争的均衡方向。 相似文献

国际油价波动对中国经济影响的评估 总被引：1，自引：0，他引：1
文章运用一般均衡分析方法,通过修正传统CGE模型关于完全竞争与固定规模报酬的不合理假设（此即我国能源市场中两个甚为重要却常被忽略的特性）,评估国际油价上涨对我国总体经济与产业的影响。研究表明,国际油价波动对我国经济冲击幅度的评估受到生产技术与订价行为设定方式的影响。只考虑非完全竞争而忽略规模经济时,冲击幅度与传统CGE相差不大,均明显低于同时考虑规模经济与非完全竞争市场结构时的冲击幅度。与国外文献在油价上涨初期所做的预测相比,本文结果较为缓和,显示由需求拉动的油价上涨,对我国实际GDP的冲击并不如预期中的严重。 相似文献

This study empirically examines what drives candidates to oppose a free trade agreement (FTA), focusing on the difference in electoral rules and progress of FTA negotiations. We use as case studies Japan's 2013 and 2016 Upper House elections, a main issue of which was the Trans-Pacific Partnership (TPP). Candidates’ promises about the TPP are unrelated to whether they run for one-seat, multi-seat, or proportional representation constituencies. Candidates who have more rival candidates belonging to the same party are less supportive of the TPP, whereas candidates who face fiercer competition with rival candidates of other parties are more supportive. This result, however, is not observed after the conclusion of the TPP negotiations. The presence of agriculture in local economies relates to candidates’ opposition of the TPP before the conclusion of negotiations, but not thereafter. Conversely, candidates’ stances on the TPP are affected by their parties’ policies and own ideologies regardless of the different stages of promoting the TPP. These results indicate that the major determinants of candidates’ positions toward an FTA vary according to the changes in circumstances surrounding the FTA. 相似文献

供应商管理用户库存(VMI)作为一种有效的补货机制,能对购买渠道的需求信息做出积极正确的反应。现在对VMI系统的研究往往集中于单个零售商和单个供应商组成的系统,不考虑VMI系统受市场上其他零售商或供应商的影响。一般来说,在独立的单个零售商和单个供应商间导入VMI系统后,零售商在短期和长期内都能获利,而供应商的利润变化则是不确定的,供应商往往在短期内会损失利润,在长期内则会获利。文章研究表明,当零售商所处的市场为垄断竞争市场,在零售商和其对应的供应商间导入VMI系统后,零售商在短期内能获利,在长期内利润不变 相似文献

This paper develops a production-based model for analyzing a role of asset trade in pooling risks among countries and provides new evidence for the international consumption-output puzzle and risk sharing among countries. Efficient risk sharing rules among countries are the same as the conditions for full financial integration. Input prices and interest rates as well as technology shocks are found to be the driving variables for cross-country output co-movements. The international correlation puzzle reflects an inability to account for production risk sharing among countries in previous studies. The degree of international risk sharing is substantial relative to earlier estimates, which is largely realized from pooling production risks rather than consumption risks among countries. 相似文献
