This paper endogenizes the number of firms in an industry with positive network effects, complete incompatibility, and firms that compete in quantity. To this end, we compare two possibilities: free entry and second‐best number of firms (the one that maximizes social welfare). We show that with business‐stealing competition, free entry yields, in general, more firms than the socially optimal solution. In addition, we find that by the nature of the industry with firm‐specific networks, total production may be greater or lower under free entry than with a regulator; moreover, some industries attain their maximum social welfare with a monopoly.  相似文献

Developing countries today have become more active participants in regional trade agreements. This raises questions about how the benefits of integration are distributed, and the extent to which lower‐income countries are able to capture development gains. Historically, such impacts have been difficult to identify with precision. This paper seeks to address this gap by empirically analysing the impact of regional integration on development, particularly the effects on growth and welfare. Using both bilateral and regional integration measures, we show that the ability to capture gains from integration varies across developing country regional groups, with developing Asia benefiting on par with developed countries. The findings in the paper indicate that trade and trade policy play an important role in reducing inequality and poverty in developing countries. It also shows that regionalism can function as a channel to make multilateralism a more adept way of addressing national challenges.  相似文献

As the formal process of Brexit has already started, there is much uncertainty about Brexit's impacts on Britain's social, political and economic future. This paper examines the economic impact. After briefly discussing some significant EU treaties that serve as the background materials, it presents the key arguments advocated by the leave and remain camps. The economic impact depends critically on the negotiation outcomes. Aside from the debate on the divorce costs, there are numerous issues that must be negotiated, such as immigration, trade in goods, services, agriculture, fisheries and financial regulations. We discuss various scenarios of possible new trade regimes, resulting in different impacts on the UK economy. With each side having its bargaining chips to play, the trade‐offs between “give and take” in the negotiation game are analysed. Considering various strategic options, this paper urges rationality and cooperation, especially weighing both sides’ entwined economic interests, in addition to their mutual security, defence, environmental and world concerns. The potential gains and losses in the event where the UK contemplates new trade arrangements with the non‐EU countries are analysed in the Appendix .  相似文献

为了掌握福鼎市桐江溪卤乙酸(HAAs)的含量、时空分布规律及其来源,对水体中HAAs化合物进行取样调查。根据桐江溪水文情势及沿岸特点设置10个取样点,于2017年12月及2018年7月按照涨潮、退潮情况分别对水样进行采集,检测HAAs分布情况,同时将卤乙酸(HAAs)与水质特性、涨退潮进行了相关性分析。研究发现,HAAs是普遍存在于桐江溪中的污染物质。其中,一氯乙酸(MCAA)、二氯乙酸(DCAA)、三氯乙酸(TCAA)、一溴乙酸(MBAA)、二溴乙酸(DBAA)等5种卤乙酸(HAA_5)质量浓度为0.44~3.39μg/L;一氯乙酸(MCAA)、二氯乙酸(DCAA)、三氯乙酸(TCAA)、一溴乙酸(MBAA)、二溴乙酸(DBAA)、三溴乙酸(TBAA)、一溴一氯乙酸(BCAA)、一溴二氯乙酸(BDCAA)、二溴一氯乙酸(CBDAA)等9种卤乙酸(HAA_9)质量浓度为0.83~56.15μg/L。桐江溪中HAAs主要为DCAA,TCAA,TBAA 3种,其中DCAA为制药厂及医院排水导致,主要分布在下游;TCAA主要来源于河段上游的农业生产活动;TBAA为上游沸石矿尾矿库受雨水冲刷而流入的Br~-所生成,主要分布于河流中下段。相关性分析结果表明,温度与HAA_5,HAA_9质量浓度呈现正相关,pH值与HAA_5,HAA_9质量浓度呈现负相关;TCAA质量浓度于相同季节不同潮汐及不同季节相同潮汐时均呈现上游高于下游的现象,其他HAAs均不因涨潮、退潮的差异造成质量浓度分布的变化。掌握桐江溪HAAs的含量、时空分布规律及来源,探讨其与水质的相关性,对于净水工艺选择、水厂出水HAAs含量的溯源分析、水体环境风险评估以及研究水生生物体内HAAs的累积效应等有重要意义。  相似文献

With sluggish external demand and increasing trade protectionism by the USA and the European Union, China is facing severe challenges in implementing its deeper, ongoing reforms. To respond actively to such challenges, the Communist Party of China's 19th National Congress proposed to “promote a new pattern of all‐round opening up.” In particular, the establishment of free trade ports is considered an important means to realize deeper integration with the world economy. This paper discusses the background, the motivation, the possible challenges as well as a feasible path for the successful implementation of free trade ports in China. Based on the international experience, the construction of free trade ports in China requires freer trade in goods, high mobility of talent and free capital flow.  相似文献

中共十九大为中国自由贸易试验区下一步的发展指明了方向。中国自由贸易试验区在经济市场化方面取得重大进展,颁布了一系列法律规范,旨在营造国际化、法制化和市场化的营商环境,但在开放方面还不够深入和系统化,因此十九大为自由贸易试验区的进一步发展提出了更高目标,指明了新的方向。我们建议把每个自由贸易区分为海关监管的自由贸易区和非海关监管的改革试验区。自由贸易区把成熟的经验推广到改革试验区,改革试验区再把经验推向全国。所有的自由贸易试验区采用不同模式,包括货物贸易和服务贸易自由贸易区、直接投资与金融自由贸易区和金融中心自由贸易区等。  相似文献

Abstract

This article surveys the changing role of fraud (dishonest and immoral commercial practices) in public justifications for corporate management of overseas trade in England across the seventeenth century. It argues that the perceived likelihood of fraud in international commercial settings played a critical role in public justifications for trading corporations at the beginning of the seventeenth century. The article suggests that these justifications were challenged from the 1690s. It explores three aspects of this challenge: first, the ways in which agents of the East India Company convinced the Company to liberate private trade (an activity previously defined as fraudulent by the Company and the Courts); second, the arguments from the 1680s that depicted the joint-stock corporation as an unaccountable, soulless entity whose claim to public trust looked less credible; third, how decades of accumulated experience of international trading contexts (and interactions with non-European merchants) prompted pamphleteers to promote the possibility (and reality) of unregulated trade in those settings. All three helped to erode the former association between private individual trade in international contexts as likely to encourage dishonesty, immorality, and fraud. This change therefore led to the corporate body itself becoming a possible vehicle for fraud rather than the individual international merchant (who the corporation was meant originally to regulate). The article analyses public deliberations about fraud and corporations to make interventions in the history of economic thought, the history of trading companies, and the history of economic crime (and especially its rhetorical role in debates about the regulation of trade).  相似文献

制定海南自由贸易港法在我国立法史上是全新的创举,彰显了中国坚定不移对外开放的决心和信心。草案赋予了海南省人大及其常委会就贸易、投资及相关管理活动制定法规的权力,这是创新性的授权立法。草案需要增加对自由贸易港的定义,以法律明确海南自由贸易港是最高开放形态的定位。在框架结构上需借鉴通行国际经贸规则,调整数字贸易条款和金融服务条款的内容。在管理职权、清单制定的主动权等方面,要遵循充分赋予海南改革自主权原则,通过法律方式将行政许可权下放给海南。在税费征收问题上,明确税费的底线与上限,给市场主体以明确的预期。同时增加评估条款,将行之有效的对海南自由贸易港建设进行评估的做法予以制度固化。通过对草案的这些修改,以期未来通过的海南自由贸易港法更为完善。  相似文献

Abstract

Development strategies followed by many countries in the 20th century bestowed a relevant role to the State. During the 1970s, it all reversed, and free markets became paramount to efficiency. F. von Hayek and the Mount Pelerin Society led the way to eliminate the State as a significant economic player, while P.T. Bauer extended such ideas to development economics, which would eventually give way to the Washington Consensus. Beyond actual results of such policies, it is surprising to see the appeal of Bauer’s theoretical approach, considering that it is constructed disregarding both empirical evidence, as well as the abundant discussion on development that was taking place contemporarily. This article explores the theoretical process of such reversal in development economics theory.  相似文献

从“海南自贸区(港)建设”战略、链接国家“一带一路”倡议视角出发,建立海南现代物流与对外贸易指标评估体系,根据协调发展度模型对海南2009-2018年现代物流和对外贸易发展的协调性进行测评。结果显示:海南现代物流综合发展指数高于对外贸易综合发展指数,海南对外贸易发展滞后于现代物流发展;海南现代物流与对外贸易发展逐渐呈协调发展趋势,二者协调发展水平不断提高。在此基础上提出强化国际物流协同建设、拓展对外贸易新业态与新模式等促进海南现代物流与对外贸易协调发展的建议。  相似文献
