不完全竞争市场上的贸易和产业政策——以合成橡胶行业为例的经验分析

战略性贸易政策理论研究不完全竞争市场的贸易政策和产业政策。本文将该理论作为分析框架，以合成橡胶行业为分析对象，使用2003年的数据对我国在该行业实施贸易政策和产业政策进行经验分析。文章分析比较了4种不同的政策或政策组合，即自由贸易政策、进口关税政策、生产补贴政策、进口关税与生产补贴结合使用。研究发现，相对于自由放任政策，各种干预政策可增加国民福利，但幅度不大；而干预政策对不同行业厂商利润和政府收入的影响则要大得多，并使合成橡胶的数量和价格发生明显变化。最后，笔者考察了进口关税政策在多期的实施效果。研究结果支持传统幼稚工业保护论：贸易保护程度应随时间减弱，并且政策将在多期中不断降低厂商的市场力量。     

CAPITAL INFLOW UNDER VOLUNTARY EXPORT RESTRAINT

This paper investigates the welfare consequence of exogenous capital inflow for the host country when the source country implements ‘voluntary export restraint’. In an imperfectly competitive market with an increasing returns to scale (IRS) sector, we show the possibility of welfare immiserization. Two channels are identified leading to immiserization. First, and this is direct, resource reallocation following capital inflow can squeeze the underproduced sector and reduce welfare. Second, contraction of the IRS sector can raise the return to capital, even when the price of the capital‐intensive importable falls unambiguously. Thus, even with an improvement in commodity terms of trade, the factor terms of trade can worsen and reduce welfare.     

贸易自由化福利收益模型和我国服务贸易发展的现实选择

通过构建福利收益模型,将服务贸易自由化和货物贸易自由化的收益进行比较,可得出如下结论:服务贸易自由化比货物贸易自由化的收益大。以发展服务贸易为主,实现服务贸易的自由化是贸易自由化发展的高级阶段,但我国目前的服务贸易发展水平还不具备这种条件。针对我国服务贸易及服务业中存在的问题,本文为提高服务贸易竞争力、促进服务贸易自由化提出了相应的政策建议。     

服务业贸易自由化对开放国的福利影响

本文以福利经济学和李嘉图模型为理论基础,建立了一个探讨服务贸易自由化对一国经济福利影响的理论模型。通过实证分析,探讨了当东道国服务部门内的特定要素实现贸易自由化之后,外国特定要素不断流入东道国服务部门对东道国经济福利的影响,并对我国在服务业对外开放中应注意的问题提出了几点建议。     

国际贸易技术溢出对我国的影响——基于工业制成品部门的GTAP模型分析

本文运用GTAP模型实证模拟了北美等八大区域工业制品部门的技术进步对我国经济发展、国际贸易及社会福利等方面的影响。研究发现:八大区域均能通过国际贸易技术溢出促进我国工业制成品部门技术的进步及社会福利的增加;但与Jaumotte(1999)和Connolly(2003)等文献结论不同,俄罗斯、北美和欧洲等区域对我国工业制成品部门产出及GDP增长至少在短期内有较大冲击,并会加大我国的贸易逆差。     

Optimal trade,industrial, and privatization policies in a mixed duopoly with strategic managerial incentives

Abstract

This paper examines optimal trade, industrial, and privatization policies in a home-market model of mixed international duopoly with strategic managerial incentives. Under linear demand and constant marginal costs, the optimal degree of privatization is shown to depend crucially on cost and demand parameters and on the availability of strategic trade and industrial policies. If both firms are equally efficient, optimal trade and industrial policies drive out the foreign firm and the privatization policy loses its effect on national welfare; however, if the home firm is less efficient, then full privatization combined with an import tariff and a production subsidy is optimal for the home country, while an export subsidy is optimal for the foreign country. If trade and industrial policies are unavailable and if both firms are equally efficient, full state-ownership, which drives out the foreign firm, becomes optimal; however, if the home firm is less efficient, only partial privatization is optimal, The state-ownership share is increased if either the market size grows, the home firm's efficiency increases, or the foreign firm's efficiency decreases. Further, the paper demonstrates the potential conflict between privatization and trade liberalization policies.     

A Meta‐Analysis of General and Partial Equilibrium Simulations of Trade Liberalisation under the Doha Development Agenda

Model‐based simulation of welfare effects is commonly used to make a case for trade liberalisation and to inform participants and stakeholders in trade negotiations. However, the simulated welfare effects of trade liberalisation vary greatly, even across studies that model similar liberalisation scenarios. This undermines confidence in the reliability of model‐based simulations. A meta‐analysis of over 100 studies that model WTO Doha Development Agenda trade negotiation outcomes is employed to identify characteristics of models, databases and liberalisation experiments that influence simulated welfare effects. Meta‐regressions produce plausible results and explain a significant proportion of the variation in simulated welfare effects in a representative sample of Doha Development Agenda trade liberalisation studies. Results also reveal that many quantitative trade policy simulation studies fail to adequately document the assumptions and data on which they are based.     

A general equilibrium analysis of foreign investment and intersectoral linkage

In this paper, we demonstrate that a foreign capital induced growth in a protected sector, which provides an industrial input for agricultural products, may increase welfare even after the entire foreign capital income is repatriated. Such a policy may lead to an increase in the volume of trade along with an increase in the size of the protected sector, quite contrary to the usual perception. The analysed structure also incorporates migration and unemployment.     

FTA网络化发展中的“轮轴-辐条”模式:福利效应与中国的参与战略

由不同类型、不同规模的"轮轴—辐条"结构组成的错综复杂的FTA网络成为区域经济一体化的新模式,相关国内外文献较少从微观视角涉及这种新模式的福利效应分析。本文在一般均衡垄断竞争模型基础上,分析了"轮轴-辐条"及其扩展结构下不同地位国家的福利和FTA收益以及影响因素。结果发现:(1)轮轴国与辐条国之间存在不对称收益,轮轴国取得的福利大于辐条国,轮轴有自我强化效应;(2)辐条拓补和多轮轴-辐条结构的福利分配情况复杂,受到产品替代性、贸易互补性、市场份额以及规模报酬递增水平等共同影响;(3)从轮轴-辐条结构进化到全球自由贸易将会增加辐条国的福利和贸易额,降低轮轴国的福利和贸易额。在深入考察FTA网络的构建及其稳定性基础上,墨西哥、韩国、日本、俄罗斯及南非是优先的可选FTA合作伙伴。     

Regional Trade Agreements versus Global Trade Liberalisation: Implications for a Small Island Developing State

This study undertakes an empirical investigation of the macroeconomic and sectoral impacts of two forms of regional trade agreements vis‐à‐vis global trade liberalisation on a small island country, using Fiji as a case study. In order to capture the feedback effects of such a complex set of policies, we employ a dynamic computable general equilibrium model of the Fijian economy to investigate (i) the impact of the Pacific Island Countries Trade Agreement (PICTA), (ii) the impact of PICTA, the Pacific Agreement for Closer Economic Relations (PACER), and the Economic Partnership Agreements (EPAs), (iii) the impact of full tariff liberalisation (i.e. tariff removal only), and (iv) the impact of full trade liberalisation, with removal of both tariff and non‐tariff barriers. While PICTA consistently provides the least benefits across a range of macroeconomic indicators including real output, welfare, trade volumes and employment, full trade liberalisation involving the removal of tariff and non‐tariff barriers provides the greatest benefits compared to the other scenarios in terms of real output. However, the latter scenario is outperformed by PICTA, PACER, the EPAs and full tariff liberalisation in terms of welfare effects, trade volumes and employment. The policy implications hold important lessons for developing countries considering trade liberalisation.     

Does value chain integration dampen producer price developments? Evidence from the European Union

We draw on trade theory to empirically explore the effects of value chain integration on producer price dynamics. Using the EU as an example of an integrated area, we construct measures of backward and forward linkages with intra‐ and extra‐EU trading partners at the country‐sector level. We find that especially upstream integration and EU accession dampen inflation. The results for downstream integration indicate a price‐increasing relationship. We propose novel EU integration indicators and offer insights to both theory and applied research. We also add to the policy debate on the price effects of (dis‐)integration of EU countries.     

The Effect of Aggregation Bias: An NTB‐modelling Analysis of Turkey's Agro‐food Trade with the EU

We explore how different data aggregation levels affect the gravity estimates of non‐tariff barriers (NTBs) in the agro‐food sector, and we examine their related impacts on policy simulations of an expansion to the European Union (EU) that would include Turkey. We calculate two sets of ad valorem equivalents (AVEs) of NTBs using the gravity approach to disaggregated and aggregated Central Product Classification data for 15 Global Trade Analysis Project (GTAP) agro‐food sectors. We find that the AVEs of NTBs vary substantially across products and that using aggregated data primarily results in greater effects of NTBs. In a second step, we incorporate the AVEs of NTBs into the GTAP model to evaluate Turkey's EU membership and conclude that aggregation bias has considerable effects on both the estimation of NTBs and the general equilibrium simulation results. Utilising different data aggregation levels leads to a great variability of trade costs of NTBs and, hence, to misleading trade and welfare effects.     

Bilateral versus Multilateral Trade and Investment Liberalisation

To assess the welfare effects of bilateral versus multilateral trade and/or investment liberalisation in general equilibrium, we set up a three‐country and three‐factor knowledge‐capital model of trade and multinational activity. Numerical simulation results indicate that multilateral liberalisation tends to dominate bilateral liberalisation in welfare terms. A transition economy tends to prefer bilateral over multilateral liberalisation to avoid plant relocation. For similar reasons, a developed country may prefer bilateral over multilateral liberalisation, if the other economies exhibit big relative factor endowment differences.     

A trade theoretic analysis of outward capital flows: with special reference to Hong Kong

This paper sets up a trade theoretic model to explain the output, price and welfare consequences of the outward investment from Hong Kong to the Pearl River Delta. A four-good trade theoretic model is set up to incorporate some special features of the Hong Kong Economy. We assume that the economy produces four goods: an exportable good, an importable good and two non-traded goods. A special feature of the model is that one of the non-traded goods (locally produced) is also consumed by foreigners and produced under the assumption of non-competitive market framework. As tourist or business-centre trade is of great significance to Hong Kong, this model allows us to capture this phenomenon. First, precise conditions are derived regarding the decline in manufacturing output in Hong Kong. Second, it is shown that, in spite of the supply side determination of the relative price of non-traded goods, income effects in this market are of great significance in both income (welfare) and output movements. These income effects cannot be captured in industrial organization type applied work. Third, it is shown how outflow of capital affects labour productivity. A surprising result obtained for this part of the analysis is that a fall in productivity (outflow of capital and de-industrialization) creates a favourable terms-of-trade effect in the monopolized sector. The welfare effect consists of four terms: (1) a terms-of trade effect via the price of non-traded goods consumed by tourists/foreigners; (2) the loss (gain) in productivity due to an outflow of capital; (3) repatriation payments; and (4) the gains from exporting from the Special Economic Zones as well as other Pearl River Delta cities. Our decomposition has two very important features in contrast to traditional models: a terms-of-trade effect from the consumption of services and productivity gains or losses. The last point is exceedingly important for policy makers specifically if outward flow of capital affects productivity negatively.     

TRADE,NON‐SCALE GROWTH AND UNEVEN DEVELOPMENT

This paper investigates the relationship between trade and economic development using a two‐country, non‐scale growth model. Depending on the share of the expenditure for manufactured goods, we obtain two different results with regard to long‐run production patterns. Whether or not the follower country can catch up with the leader country in the long run depends on two factors: (1) the patterns of production in both countries and (2) the measure of economic welfare that is used, i.e. per capita income or per capita consumption.     

Tariff‐tax Reforms in Large Economies

This paper studies tariff‐tax reforms in a two‐region global New Keynesian model composed of a developing and an advanced region. In our baseline calibration, a revenue‐neutral reform that lowers tariffs in developing countries can reduce domestic welfare. The reason is that the increase in developing countries welfare due to higher output is dominated by the welfare losses stemming from the deterioration of the terms of trade. On the other hand, the reform increases output and welfare in the advanced countries and in the world as a whole. The effects that we highlight have not been studied in previous contributions to the literature, which looks at tariff‐tax reforms using a small open economy framework. Nominal rigidities have important implications for adjustment dynamics in our model. In the case of a ‘point‐for‐point’ reform, for example, price stickiness implies that the international dynamics of output is reversed compared to a revenue‐neutral reform.     

Foreign influence and welfare

How do foreign interests influence policy? How are trade policies and the viability of trade agreements affected? What are the welfare implications of such foreign influence? In this paper we develop a model of foreign influence and apply it to the study of optimal tariffs. In a two-country voting model of electoral competition, we allow the incumbent party in each country to take costly actions that probabilistically affect the electoral outcome in the other country. We show that policies end up maximizing a weighted sum of domestic and foreign welfare. Using this formulation we show that foreign influence increases aggregate world welfare when there are no other means of alleviating the externalities that arise from cross-border effects of policies. In contrast, when countries can engage in international agreements, foreign influence can prove harmful as powerful countries may refuse to offer concessions. We also show that power imbalances are particularly detrimental to cooperation when they are positively correlated with economic size.     

我国战略性贸易政策实践

本文对改革开放以来我国的战略性贸易政策实践进行了分析。虽然我国政府从未明确提出要实行战略性贸易政策,但是通过和日本经济高速增长时期的战略性贸易政策相比较,可以发现,在我国广泛推行的产业政策中,战略性贸易政策早就存在。只是由于产业组织政策失效所导致的市场竞争程度低下,使得我国战略性贸易政策的实施效果很不理想。因此,协调产业政策和竞争政策,打破地方保护,建立国内统一大市场就成为我国今后战略性贸易政策成功的关键。     

Who in Brazil Will Gain from Global Trade Reforms?

The potential impacts of multilateral trade liberalisation on developing countries are the subject of numerous controversies. One particular concern is that Brazil, a major agricultural exporter and a country with one of the world's most unequal income distributions, will reap a substantial share of the potential benefits to developing countries from agricultural trade reform, and that most of those benefits will go to large‐scale commercial farmers rather than to the country's smallholders. This claim is explored via a global general equilibrium model and a national model of Brazil containing multiple agricultural and non‐agricultural households. Brazil is found to account for nearly one‐half of all the benefits to developing countries deriving from global agricultural trade reform. These gains are associated with improvements in the welfare of each group and a lower incidence of poverty. Large‐scale producers gain more than smallholders as they tend to be relatively specialised in export products, but there are important gains to agricultural employees, who are relatively poor, and to urban households, who benefit from the expansion of the agro‐food sector. Overall, there is no discernible impact on income inequality, and no evidence that the gains to commercial farmers occur at the expense of poorer households.
