State Trading Enterprises as an Impediment to Improved Market Access: The Case of the Korean Rice Market

The trade and welfare effects of tariffs are well known. Less well known, and more difficult to analyze, are the economic effects of state trading enterprises (STEs). Despite STEs in importing countries having the potential to limit market access, they are no longer on the agriculture agenda in the Doha Round Negotiations in the WTO, because some Members have asserted that importing STEs do not distort international trade. We evaluate this assertion through the use of a theoretical model of an STE, which is calibrated to data for the Korean rice market. We show that this STE does distort international trade by restricting market access relative to a Cournot benchmark, and that it affects the domestic and international distribution of social welfare. This finding permits the conclusion that an important opportunity is being missed in the negotiations to improve market access, because importing STEs are not on the agenda.     

Do state trading exporters distort trade?

In this paper, we analyse the trade-distorting effects of state trading enterprises (STEs) which exist in some exporting countries. Because of these potential effects, several countries have raised the issue of state enterprises in the Doha Round negotiations in the WTO. The belief is that STEs in certain developed countries have trade effects which are equivalent to an export subsidy. STEs also exist in developing countries, though since the aim of government policy may differ from the developed country case, the trade distortion may be equivalent to an export tax. We present a theoretical model that is sufficiently general to allow us to consider the case of exporting STEs in developed and developing economies. The model is calibrated with data on two examples of STEs, one typical of an STE in a developed country, the other typical of an STE in a developing economy. In each case, we allow for differences in the nature of the STE's pay-off function. The overall conclusion is that STEs do distort trade and the trade distortion effect is potentially significant.     

Redistribution,state trading enterprises and ‘politically optimal’ tariffs

State trading enterprises (STEs) are widely used and can be viewed as instruments of trade policy. We analyse two aspects: the first is their potential trade distorting effect; the second is how they modify the case for the ‘politically optimal’ tariff. We show that the STE can reduce the need for a tariff designed for domestic redistribution. This result introduces some ambiguity about how STEs are interpreted: from a multilateralist perspective, they should be dealt with in the same way as other non‐tariff barriers; from a nationalistic perspective, they can reduce the need for ‘politically optimal.’     

Trade prices and supply in the UK economy

Current account imbalances are a major source of instability in the world monetary and trading system. Measures to correct these imbalances have largely involved adjustments to exchange rates. In the international trade literature, when the current account is in deficit, the Marshall-Lerner condition is sufficient for a successful devaluation. However, this partial equilibrium condition — apart from being based on the assumption that supply elasticities are infinite — abstracts from how the domestic economy responds to the change in relative prices. In this paper we develop a model of price and output determination in an open economy with imperpectly competitive markets, and draw a distinction between goods which are exported and those which are supplied to the domestic market. This means that we have to determine jointly both export prices and the domestic price of house sales. We show that as long as there is no money illusion in the labour market a fall in the nominal exchange rate raises domestic and export prices proportionally and leaves trade volumes unaffected. However, shifts in domestic absorption relative to overseas demand — by changing relative prices — cause shifts in the relative supply of exports and domestically sold goods and affect the trade balance. Thus fiscal and monetary measures directed towards reducing domestic absorption are more likely to be successful in correcting current account imbalances than exchange rate depreciation.

State Trading and Tariff Rate Quotas: The Case of Korea's Rice Imports

This paper analyzes the effects of trade liberalization of tariff‐rate quotas under import “state trading enterprises” (STEs) in agriculture. An analytical framework is provided to determine the importance of which instrument is binding under competition (the in‐quota or out‐of‐quota tariff or the quota) and under the initial STE equilibrium. It also depends on whether or not the STE controls both the domestic market prices and owns/controls the import quota (and whether it is obligated to fill the quota or not). An empirical example of the rice STE in South Korea has simulations showing that an increase in imports can be achieved through a moderate expansion of the quota or a decrease in the out‐of‐quota tariff to the level where it becomes binding. However, a significant level of quota expansion induces the STE to switch to the autarky solution and social welfare declines.     

Assessing the Impact of State Trading Enterprises

State Trading Enterprises (STEs) are periodically subject to intense scrutiny for their suspected negative impact on the international trade of agricultural goods. Sound empirical assessment of the impact of STEs is scant, in spite of the ongoing and intense debate over their impacts, especially in the context of reform at the WTO. In this paper we use the case of world wheat trade between 2212 country pairs over a 35 year span to assess STE impacts. Using a gravity model, we estimate a Poisson pseudo maximum likelihood fixed effects model of world wheat trade to assess the role of both the presence of STEs and STEs with monopoly power. Further addressing estimation challenges, we also estimate zero-inflated versions of Poisson and Negative Binomial Regression models. We find consistent support for the hypothesis that monopoly export STEs are associated with higher exports for their host country. Similarly, import STEs appear to inhibit wheat imports, suggesting a protectionist function.     

贸易的技术创新效应*——国内外贸易联动与部门间分工的权衡

国际贸易可以通过技术溢出提升一国的技术创新水平,但发展中国家的价值链低端锁定却可能阻碍技术溢出效应的实现。在引入国内贸易的分析视角后,国内外贸易联动发展有助于提升贸易的技术创新效应。国内外贸易联动可通过竞争驱动效应、信息扩散效应与价值链组接效应强化技术溢出在竞争、模仿、上下游联系等方面的影响,进而推动技术创新。而国内外贸易部门专业化则在其中发挥着正向调节作用。本文构建了国内外贸易联动指标,通过面板固定效应、面板分位数模型对相关作用机制进行了实证检验,并通过了稳健性检验。实证结果支持了国内外贸易联动对技术创新的提升作用,并且在国内贸易专业化程度较高的地区,国内外贸易联动的正面影响更强。     

GATT TRADE RULES AND THE ENVIRONMENT

This paper addresses the alleged conflict between the GATT trade rules and the protection of the environment by GATT members. The author contends that the principal objective of the GATT rules on nontariff trade restrictions is to eliminate government interventions that promote the commercial interests of domestic producers and consumers in a manner that discriminates against foreign producers and consumers in either domestic or international markets. He further contends that this objective fundamentally does not conflict with protecting GATT members' domestic environment or the global environment. The GATT should explicitly recognize the objectives of environmental protection and natural resource consemation, either by an amendment to the GATT Articles or by resolution of the GATT Council. GATT members, in the interest of protecting their national and the global environment, should be free to impose restrictions on imports or exports so long as the interventions conform to the following conditions: (i) restrictions do not have the intent or signficant effect of discriminating against foreign producers or consumers in favor of domestic ones, (ii) restrictions are in the interest of protecting the global environment where the concerns are widely shared by other nations and do not simply reflect unique and parochial views of the individual member, and (iii) restrictions do not constitute an effort to force trading partners to adopt environmental standards of production that have no global or trans-border pollution implications .     

Market access and technology adoption in the presence of FDI

This paper theoretically investigates whether improved access to the domestic market speeds up new technology adoption by foreign firms. Foreign firms choose between exporting and foreign direct investment (FDI) to serve the domestic market. If two firms compete in the domestic market, multilateral liberalization of FDI or the realization of multilateral free trade may deter or delay technology adoption, while they always promote and accelerate technology adoption if only a single firm serves the domestic market. Technology adoption can be quickest and consumer welfare greatest when the fixed cost of FDI and the trade costs are neither very high nor very low. Preferential liberalization of FDI promotes the technology adoption of the targeted firm but may not benefit consumers because it discourages technology adoption of the non-targeted firm.     

市场一体化、非对称性贸易成本与制造业集聚*

国内市场一体化将会对中国制造业的空间分布造成何种影响？本文通过构建统一的理论分析框架验证了国内市场一体化影响制造业集聚的两种机制：其一是贸易成本总体水平的调节效应,其二是贸易成本非对称性的直接效应,而调节效应的方向则取决于模型理论范式选择。此外,本文基于中国区域间投入产出数据,系统地测算了中国地区间的非对称双边贸易成本,并基于测算结果进行回归分析。实证结果表明,在中国制造业发展初期,市场结构总体符合IRS MC范式设定,此时贸易成本的调节效应倾向于促进制造业在东部沿海区域集聚。伴随着制造业生产技术的成熟,制造业市场结构开始呈现CRS PC范式特征,此时市场一体化对制造业集聚的调节效应不再显著。     

Law and Preferences

Legal rules do more than provide incentives, they change people.When preferences and norms are endogenously determined via aprocess of imitation and learning, legal rules, by affectingthe market outcome, may affect the dynamics of preference formation.Analyzing the effect of different legal rules should thereforego beyond the analysis of the incentives they provide. It shouldalso include an analysis of their effect on the distributionof preferences and norms of behavior. We illustrate this claimby considering a simple market game in which individuals mayhave preferences that include fairness concerns. We show thatdifferent legal rules change not only the pattern of trade ina market game, but also individuals' fairness concerns. Thatis, different rules may eventually make individuals care more(or less) about a fair outcome. Specifically, our model suggeststhat enhanced remedies for breach of contract may reduce equilibriumpreferences for fairness.     

Foreign trade and innovation in domestic labor relations

For the most part, neoclassical trade theory has restricted its concerns to the effect that trade has on the production and distribution of commodities. It implicitly assumes that international trade leaves unchanged the institutional structure of domestic economies.The empirical evidence presented here supports the claim that international trade induces innovation in the institutions regulating the capital-labor relationship. Existing trade theories, neoclassical or otherwise, that assume away such changes give only a partial answer to one of the central questions a theory of trade must answer: What are the effects of trade, and are these effects beneficial?     

发展可持续性外贸：规避“壁垒”风险的战略选择

随着经济的不断发展和生活水平的不断提高,人们的环境意识逐渐加强,对环境保护和绿色产品的需求日渐增长,出现了一些以保护国内消费者利益和保护国内生态环境为由,限制国际贸易自由化、保护本国市场的一些制度,这些就是绿色贸易壁垒。从短期来看,尽管绿色壁垒能对威胁人类与动植物生命健康以及破坏生态环境的贸易活动进行一定的限制,减少这些活动产生的严重后果,但是它也成了发达国家乘机“搭便车”制定苛刻的环境标准进行贸易保护的主要形式之一。中国的外贸企业应采取相应措施规避风险,以实现对外贸易的可持续发展。     

Trade,labour market rigidity,and aggregate productivity in OECD countries

As the economy becomes more open to trade, aggregate productivity can increase by driving out the least productive firms (the selection effect). Since the selection effect reallocates resources toward the more productive firms, this process can be hindered by rigidity in domestic labour market institutions. Based on the selection effect by Melitz (2003), this article empirically examines how rigidity in labour market institutions affects the consequence of trade on aggregate productivity. Findings from panel dynamic ordinary least square (DOLS) estimators suggest that a high degree of labour market rigidity in an open economy reduces Total Factor Productivity (TFP). In particular, in the case of extremely high labour market rigidity but low foreign R&D capital stocks, openness to trade can cause a country to experience decreasing TFP.     

EXCHANGE RATE PROBLEMS IN NATIONAL ACCOUNTING OF DEVELOPING COUNTRIES*

Developing countries which typically have import surpluses and inflationary pressures because of insufficient savings are prone to use indirect taxes on imports (Tm) and subsidization of exports (Sx) in order to prevent deterioration of the balance of trade. If these substitutes for devaluation are included in the net indirect tax component of product at current market prices (Ym) the import surplus is likely to be understated, and Ym upward biased. This distortion will be avoided if imports and exports are measured at effective exchange rates (ER), that is, at official rates (OR) plus Tm and Sx respectively, and if (Tm - Sx) is deducted from the net indirect tax component of Ym. Only in this manner become imports and exports consistent with the other uses and resources at market prices and can be articulated with them. At base-year prices the volume index of product at OR diverges from that of ER to the degree that the composition of imports and exports in regard to tax and subsidy rates computed ad valorem significantly changes. Such a case is similar to that of the price indexes of imports and exports moving in diverging proportions: the trade balance at base-year prices will differ from that at current prices. The resulting discrepancies in national accounts have led to proposals of deflating, for example, exports by the price index of imports. Suchlike approaches are incompatible with the principle of national accounting that prices are supposed already to measure substitution values. Deflating exports by import prices means reintroducing substitution values, as does, for example, deflation of incomes by a consumer price index. Correspondingly, since the trade balance at ER conceptually expresses the value of imports at domestic market prices as compared to the corresponding domestic market value of exports, and if at ER the trade balance diverges from that at OR, the former balance has an important meaning (as has the trade balance at base-year prices as compared to that at current prices) and the resulting discrepancy between the two measures should not be removed merely for the sake of accounting smoothness. In contrast to the market price approach, the measurement of product at base-year factor cost is indifferent to the measurement of the trade balance at ER and at OR. It is, therefore, proposed in countries in which part of import taxation and export subsidization substitutes for devaluation, to record imports and exports in the national accounts at effective exchange rates, and to correct the net indirect tax component of product correspondingly. Imports and exports at official exchange rates should be shown within the balance of payments, and the latter separately as a memorandum item.     

Border effects and the availability of domestic products abroad

Abstract.  Trade between countries could fall short of trade within a country because (1) the volume of international trade is less than the volume of domestic trade for a given product (the intensive margin); or (2) some goods that are sold domestically are simply not exported (the extensive margin). My theoretical model illustrates that either of these two factors could explain a given aggregate 'border effect.' I examine the empirical relevance of this distinction by isolating the fraction of total domestic production attributable only to exporters, finding that around one‐half of the border effect may be attributed to each explanation.

出口贸易是否提高了我国企业的生产率?——基于中国2007年制造业企业数据的检验

文章在新—新贸易理论的框架下,选取了2007年我国30多万家制造业企业样本,从总体和分行业两个方面检验了我国出口贸易对于企业生产率的影响,结果显示其不但没有积极作用,反而存在负面效应,这其中的原因可能是我国加工贸易企业较多、出口企业的惰性以及我国国内市场进入成本较高引起的。由此,我国企业应该重视提高对外贸易的质量,加快结构转型和产业升级,发挥出口贸易对于企业生产率以及经济可持续发展的积极作用。     

Foreign Investment and Endogenous Protection with Protectionist Quid Pro Quo

The literature on quid pro quo foreign direct investment describes how unwarranted investment may be undertaken because of the endogeneity of trade policy. The quid pro quo is that foreign producers, who are exporters to the host economy, invest in return for a liberal trade policy. We describe converse circumstances. The nexus between foreign investment and endogeneity of trade policy is implicit (not explicit as in quid pro quo investment), and a government with socially correct objectives (perhaps imposed by international-agency conditionality) wishes (i) to privatize a domestic firm by sale to a foreign investor who can provide technology improvement for domestic production and (ii) to pursue a liberal trade policy. The government is electorally constrained by needs of political popularity. The outcome is that efficient private investments may not be undertaken—in contrast with the quid pro quo case where in efficient investments are undertaken. While our model is general, the conditions we describe appear to be in particular present in post-socialist economies. Our model offers a contributing explanation for the slow pace of progress in many such economies, which rely on foreign technological transfer to improve the technology and product quality of post-socialist industry, but fail to receive the requisite foreign investment despite governments' good intentions.     

Monopoly power,barriers to competition and the pattern of price differentials in international trade

Numerous studies have attempted to assess the influence of market structure on performance in domestic markets of industrial countries. With few exceptions, these investigations have shown that prices and profits are higher, and a less efficient allocation of resources prevails, in markets where agressive competition is absent. Using techniques similar to there applied in the industrial market studies, this analysis examines the pattern of iron steel prices in international trade. The findings parallel those for the industrial organization investigations. Typically, international markets which are more concentrated, or which rely on a smaller number of trade contacts, bear higher prices. Also, the magnitudes of these excess price margins are such as to have important policy implications since they constitute a serious drain on the foreign exchange reserves of some developing countries.
