成本信息不对称、产品市场竞争与自动出口限制政策研究

自动出口限制政策是各国在国际贸易中经常采用的一种非贸易保护措施。结合不完全信息并同时以厂商利润、社会福利为指标,重新探讨VER的政策含义及出口国是否自愿执行的问题。研究结果发现,在本国对外国厂商信息不完全的情形下,其结果将与既有文献有所不同。若为Coumot竞争,VER将对两国产生实质的影响;对出口国而言,不论其厂商为何种类型,此时的VER政策都是非自愿的;本国的福利变化则需视出口厂商之类型而定。若为Bertrand竞争,则VER只在出口厂商为高成本类型时方对出口国有利,且不论外国厂商为何种类型,VER皆无法使两国同时获利。     

出口退税与出口促进:完全信息静态博弈分析

在不完全竞争市场中，各国都将出口贸易视为彼此间的市场份额竞争。在出口竞争中，出口退税政策之所以广受各国政府欢迎，是因为它有助于扩大本国在国际市场的份额(出口促进效应)，增加利润收益(利润转移效应)，改善本国厂商在与其它国家厂商的非合作性竞争中的相对地位。非合作性纳什出口退税均街是：各出口国政府都实行出口退税。但这不是实现共同福利最大化的最优解。     

扶持我国出口导向企业实施RRC战略的理论依据

文章探讨本国企业与外国企业在以产量竞争的方式争夺出口市场的情况下,本国政府对本国企业实施提高竞争对手成本(RRC)战略的投资进行补贴的理论依据。通过两次运用两阶段博弈,文章对由补贴政策、企业RRC投资、产量和利润水平决定构成的三阶段博弈进行了因果关系的比较静态分析,认为在一般情况下,对本国企业RRC投资补贴有利于本国企业在国际市场中产量、市场份额和利润的增加,也有利于本国社会总福利水平的增加,对外国企业产量、利润和社会福利则形成负面影响。由于RRC战略较之掠夺性定价温和且更易实施,这一政策对于保持我国出口稳定增长具有一定积极意义。     

出口导向贸易政策与发展中国家间FDI竞争——基于寡占竞争模型的理论分析

文章建立了一个两国竞争模型,重点分析了进口关税与出口补贴等战略贸易政策对发展中国家吸引FDI竞争的影响。研究发现:(1)当两国都采取出口补贴的外资激励政策时,工资水平和进口关税对发展中国家间FDI竞争并没有直接影响;(2)对全要素生产率较高的国家来说,当两国的关税水平都较高时,出口补贴政策增加流向本国的FDI,而当两国关税水平大幅下降后,出口补贴政策反而不利于本国FDI竞争。文章的结论对当前我国战略引资和出口退税等政策的调整具有重大的指导意义。     

外国技术授权策略与本国关税政策之探讨

该文将以一个拥有技术优势,且将其产品输往本国寡占市场中的外国厂商为对象,探讨其对本国厂商的最适技术授权策略,以及该策略是否受关税保护贸易政策之影响.在该文的研究结论中,我们可以发现下列三点:(1)在自由贸易条件下,当外国企业可授权国内二家厂商时,其最适授权策略,会选择同时授权于国内二家技术劣势厂商.当外国厂商仅可授权国内一家技术劣势厂商时,若市场规模相对较小,国外技术优势厂商之最适单位权利金订定为存在内部解,且会受市场规模的影响,市场规模值愈大,权利金愈高.当市场规模相对较大时,则国外技术优势厂商之最适单位权利金恰等于其技术创新所能节省的成本幅度.(2)在关税政策条件下,国外技术优势厂商可同时授权国内二家厂商时,其授权策略不受关税政策影响.在可授权国内一家技术劣势厂商时,若市场规模相对较大,其授权策略不受关税政策影响.若市场规模相对较小,在自由贸易条件下外国厂商的授权权利金将高于采取关税政策条件下的水准.(3)在本国政府的最适关税政策下,不论是当外国厂商可授权本国二家厂商之 Nash 均衡或可授权本国一家厂商之 Nash 均衡,皆有助于本国福利水准的提升.     

不完全信息、反倾销威胁与最优出口贸易政策

通过扩展Brander和Spencer(1985)的基本模型,本文首先证明了,在反倾销威胁下,基于完全信息假设的最优出口贸易政策要求出口国政府给予低成本企业更高的出口补贴或更低的出口征税,在无效激励机制下必然导致出口企业隐匿自己的真实成本类型,基于完全信息假设的最优出口贸易政策失效。在此基础上,本文进一步论证了不完全信息和反倾销威胁下激励相容的最优出口贸易政策,该政策要求出口国政府依据进口国国内要求保护压力的大小,采用不同的出口征税和一次性转移支付政策组合,激励出口企业如实报告成本类型,并使国家整体福利最大化。     

外国技术授权策略与本国关税政策之探讨

本文将以一个拥有技术优势，且将其产品输往本国寡占市场中的外国厂商为对象，探讨其对本国厂商的最适技术授权策略，以及该策略是否受关税保护贸易政策之影响。在本文的研究结论中，我们可以发现下列三点：（1）在自由贸易条件下，当外国企业可授权国内二家厂商时，其最适授权策略，会选择同时授权于国内二家技术劣势厂商。当外国厂商仅可授权国内一家技术劣势厂商时，若市场规模相对较小，国外技术优势厂商之最适单位权利金订定为存在内部解，且会受市场规模的影响，市场规模值愈大，权利金愈高。当市场规模相对较大时，则国外技术优势厂商之最适单位权利金恰等于其技术创新所能节省的成本幅度。（2）在关税政策条件下，国外技术优势厂商可同时授权国内二家厂商时，其授权策略不受关税政策影响。在可授权国内一家技术劣势厂商时，若市场规模相对较大，其授权策略不受关税政策影响。若市场规模相对较小，在自由贸易条件下外国厂商的授权权利金将高于采取关税政策条件下的水准。（3）在本国政府的最适关税政策下，不论是当外国厂商可授权本国二家厂商之Nash均衡或可授权本国一家厂商之Nash均衡，皆有助于本国福利水准的提升。     

战略性贸易政策理论的产生、发展及研究展望

战略性贸易政策理论兴起于20世纪80年代,以不完全竞争的市场结构和规模收益递增为理论基础,以战略性出口政策、战略性进口政策和进口保护促进出口的政策为主要观点。其基本结论为:政府可以通过一定的贸易干预政策改变本国厂商与外国厂商之间的博弈关系,使博弈的结果有利于本国厂商,从而提高国民福利。20多年来对战略性贸易政策理论的扩展、反驳和修正促进了理论的发展。未来的研究将更注重理论的深化和实证的丰富。     

战略性贸易政策在出口管理中的运用

一、战略性贸易政策在出口管理实践中的运用 战略性贸易政策指一国能在实际或潜在的国际市场上影响企业战略决策结果的贸易政策,它的基本主张是在具有规模经济或垄断性的行业,当本国企业与国外厂商竞争时,政府应采取关税或补贴等措施,使垄断利润从外国垄断厂商转移到本国厂商,从而使本国企业获得"垄断租".     

我国出口补贴转变为技改补贴的有效性分析

文章探讨了本国企业与外国企业在以产量竞争的方式争夺出口市场的情况下,本国政府对本国企业技改投资进行补贴的理论依据。通过两次运用两阶段博弈,文章对由补贴政策、企业技改投资、产量和利润水平决定构成的三阶段博弈进行了因果关系的比较静态分析,认为在一般情况下,对本国企业技改投资补贴有利于本国企业在国际市场中产量、市场份额和利润的增加,也有利于本国社会总福利水平的增加,对外国企业产量、利润和社会福利则形成负面影响。这一政策可接替在未来实施中具有不确定性的出口补贴政策。     

考虑港口收费管制的进出口贸易竞争研究

考虑港口的收费管制因素,建立了进出口贸易竞争模型。该模型由一个出口国和两个进口国组成,且各国都拥有一个港口,位于出口国的两家公司均向两个进口国销售商品,并在各个进口国展开市场竞争（古诺竞争或伯川德竞争）,各贸易国的港口根据其是否存在价格管制确定港口收费。针对进出口公司的每种竞争模式,得到了不同的港口收费管制组合下各贸易国的港口收费、港口利润和社会福利,并将竞争均衡结果进行了比较。研究发现： （1）在进出口公司古诺竞争模式下,若三个贸易国的港口都无收费管制（有收费管制）且进出口产品的差异较大 （小）时,各贸易国的社会福利和港口利润均更高; （2）在进出口公司伯川德竞争模式下,若进出口产品的差异较大 （小）,则出口国的港口利润主要取决于港口收费 （贸易量）,而进口国恰好相反; （3）当进出口产品的差异较大 （小）时,进出口公司在古诺 （伯川德）竞争模式下各贸易国的社会福利、港口利润以及港口使用费都更高。     

Dumping And Double Crossing: The (In)Effectiveness Of Cost‐Based Trade Policy Under Incomplete Information*

We argue that the rise of antidumping protection and the proliferation of voluntary export restraints (VERs) are fundamentally interrelated. We show that both can be explained by a cost‐based definition of dumping when the domestic government has incomplete information about the foreign firm's costs. Given that its costs are only imperfectly observed and knowing the government's incentives to protect, efficient foreign firms will voluntarily restrain their exports prior to the antidumping investigation. In turn, the VER distorts the government's perception of the foreign firm's efficiency and leads to undesirably high duties regardless of the foreign firm's efficiency.     

跨国多期技术授权方式选择及社会福利分析--基于空间数量歧视竞争的框架

跨国技术授权作为企业获得竞争优势的重要途径已经受到理论界的关注。与以往的内部技术授权研究不同,文章构建了一个外国拥有技术的企业与东道国企业的空间数量歧视竞争模型,考察多期技术授权存在技术泄露、关税内生及空间竞争对外国拥有技术的企业的最优授权策略选择以及东道国社会福利的影响。研究表明：(1)外国拥有技术的企业偏好双重收费方式,且固定收费方式优于特许权收费方式;(2)双重收费方式不能同时实现拥有技术的企业和社会福利的最优,但可以实现社会福利的次优;(3)外国企业应该通过双重收费方式或固定收费方式进行技术授权,而东道国政府不应一味地提高关税水平,适当地降低进口关税有利于跨国技术授权的实现。文章的结论对于发展中国家的技术引进以及技术出口政策的制定具有一定的现实意义。     

Who Benefits from Voluntary Export Restraints?

Using a simple Cournot-oligopoly model, the paper examines the effects of voluntary export restraints (VERs) on profits, market shares, consumers' surplus, and domestic welfare when the domestic market is open to foreign direct investment (FDI) or exports from a third country. A VER may induce FDI from the VER-restricted country or exports from the third country. Under certain circumstances, the domestic firm loses from a VER. Even if the domestic firm gains, the increase in the market share of the domestic country induced by the VER could be less than that of the third country.     

The Impact of Exporting and Export Destination on Manufacturing Wages: Evidence for Sub-Saharan Africa

This paper investigates wage effects of trade status of African firms. Using data for manufacturing firms, we find a positive overall association between individual earnings and export status. Moreover, the skill wage premium in exporting firms is significantly higher. These results are consistent with either trade inducing higher wages in the exporting country, or with more productive (higher wage) firms self‐selecting into exporting. The results are not robust, however, to disaggregation by export destination. Exporting to outside Africa generates a negative wage premium whereas exporting to African markets yields a positive premium in export firms of the exporting country. This suggests that there is a disciplining effect on the wages of exporting firms only when exporting is to more competitive markets.     

Why exporting countries agree to voluntary export restraints: the oligopolistic power of the foreign supplier

This paper studies the impact of VER on an exporting country. It shows that a VER at the free‐trade level favours the concentration of industry, allows firms with an export licence to expand, causes the contraction of the size of the firms producing for the domestic market only, and raises the price mark‐up in the domestic market. The impact on welfare is indeterminate depending upon the effect on global efficiency. If a VER is binding, also the price mark‐up in the foreign market rises and this effect on terms of trade, ceteris paribus, is welfare improving. An applied general equilibrium model for Turkey supports the conjecture that with a VER the increased oligopolistic power of incumbent firms with an export licence, the higher price mark‐up in the domestic market and a possible social welfare gain, are the key elements in understanding the rationale behind VERs. However, if authorities induce firms to engage in unproductive profit‐seeking activities, rent dissipation occurs and the impact on social welfare becomes negative.     

Foreign Aid under Quantitative Restrictions: Welfare Effects and International Factor Mobility

Using a two‐country, general‐equilibrium model of international trade, this paper incorporates pre‐existing quantitative trade restrictions and international factor mobility into the transfer problem analysis. The effects of foreign aid on the welfare of both the donor and recipient nations are identified under each form of quantitative trade restriction: quotas and voluntary export restraints (VERs). In doing so, this paper identifies conditions under which international transfers are strictly Pareto‐improving (i.e. increase global welfare). A central result of this analysis is the direct welfare effect of a transfer received by a nation with quota‐constrained (VER‐constrained) imports is enhanced (may be enhanced) by a worsening of the recipient’s terms of trade.     

Reaching up and reaching out: The impact of competition on firms’ productivity and export decisions

Using firm‐level data from 139 countries, this paper investigates the effect of competition in both the domestic and foreign markets on firm productivity and export decisions. Applying a sample selection endogenous treatment (SSET) Poisson model that tackles both the issue of endogenous sample selection and endogenous treatment at the same time, we document robust evidence that strong competition in the domestic market propels firms to be more productive, and decreasing domestic competition increases firms’ propensity to export. However, firms’ export intensity (i.e. how much they export) is not directly influenced by competition in the domestic market. Moreover, lower competition in the foreign market increases the propensity of domestic firms to export, enlarging the set of exporting firms to include firms with relatively smaller export amounts.     

On the International Linkages between Trade and Merger Policies*

In a three‐country model, this paper investigates linkages between merger incentives of exporting firms and the trade policy of an importing country. When exporting firms come from only one country, the tariff response of the importing country reverses the welfare effects of a merger in the exporting country. If there exist two exporting countries, a merger creates two types of conflicting international externalities. First, a merger in one exporting country increases profits of all firms. Secondly, non‐merged firms lose if the importing country is free to raise its tariff in response to a merger of foreign exporters.
