Export Subsidies and Exchange Rate Pass‐through

This paper investigates effects of exchange rate on optimal trade policies and market prices within a standard export subsidy model. Shifts in exchange rate change relative efficiencies of firms in different countries. We show that depreciation of own currency increases subsidy levels when marginal cost is constant. Import dependency weakens this relationship, decreasing sensitivity of subsidy levels to depreciation. In general, subsidies reduce exchange rate pass‐through. Additionally, perverse exchange rate pass‐through effect arises with sufficiently intensive subsidies.     

ENDOGENOUS MARKET STRUCTURES AND STRATEGIC TRADE POLICY*

I characterize the optimal export promoting policy for international markets whose structure is endogenous. Contrary to the ambiguous results of strategic trade policy for duopolies, it is always optimal to subsidize exports when entry is endogenous, under both quantity and price competition. With homogenous goods the optimal export subsidy is a fraction 1/ε of the price, where ε is the elasticity of demand (the exact opposite of the optimal export tax in the neoclassical trade theory). Analogously, I show the general optimality of R&D subsidies and of competitive devaluations to promote exports in foreign markets where entry is endogenous.     

The Political Economy of Strategic Trade Policies*

This paper applies Grossman and Helpman's (1994 ) common agency model to investigate the formation of strategic export subsidy and strategic import tariff under both Cournot competition and Bertrand competition. The results of this paper indicate that even with political pressure, the Grossman–Helpman politically‐determined export policy is identical to the rent‐shifting export policy, which is export subsidy (export tax) in Cournot (Bertrand) competition. The politically‐determined import tariff will be higher than the optimal level. This paper highlights the possibility that lobbying can restore the level of trade intervention to a more efficient one in the absence of the benevolent dictator.     

Optimal Trade Policy under Homogeneous Bertrand Competition*

In a seminal paper, Eaton and Grossman (1986) conclude that an export tax is optimal if firms produce heterogeneous products and engage in Bertrand price competition. In particular, they made a comment that could be interpreted to mean that even in the case of a homogeneous product, the optimal policy is still an export tax. This paper has re‐examined the case and found that the optimal export policy can be an export subsidy, free trade, or an export tax, depending on the marginal cost differential between the domestic and the foreign firms. Moreover, if government intervention entails a cost, free trade becomes the only optimal policy.     

Strategic Trade Policy with Heterogeneous Costs

The paper examines optimal strategic trade policy under a heterogeneous cost oligopoly. The first‐best policy involves a structure of firm‐specific export subsidies/taxes in which the government favours the most efficient firms only with a sufficiently low social cost of public funds.     

STRATEGIC EXPORT POLICY IN VERTICALLY RELATED MARKETS

This paper analyses how strategic export policies are affected by introducing an imperfectly competitive intermediate good into a Bertrand duopoly model with product differentiation, where a home and a foreign final‐good firm export to a third‐country market. It is shown that when the home and foreign markets for the intermediate good are segmented, the optimal export policy towards the final good is a tax. In contrast, under integrated markets, the optimal export intervention is a subsidy. Whether bilateral export intervention is welfare improving compared with free trade, depends on the degree of product differentiation between the home and foreign final goods.     

Advertising Subsidy and International Oligopolistic Competition

This paper examines the strategic role of advertising subsidies in a third‐country trade model in which two firms located in different countries export their products to a third country. First a basic model of advertising in oligopolistic industries is developed in which firms decide how much to invest in either predatory or cooperative advertising and then engage in product market competition either as Cournot competitors or as Bertrand competitors. It is shown that firms invest in only one form of advertising; which form they invest in depends on the relative effectiveness of the two types of advertising, the degree of product differentiation, and the form of product market competition. The paper then studies strategic industrial policy and shows that an advertising subsidy is the optimal strategic policy irrespective of the form of product market competition and the form of advertising in which firms invest.     

Industrial heterogeneity and international product cycles

We analyze the superiority of the specific, demand and cost ad valorem subsidies in industrial and export policies. The criterion employed to measure the ranking of the superiority of the subsidy policies in this paper is that, given an identical total output, the smaller the amount of the subsidy, the superior the subsidy policy. We show that the demand ad valorem subsidy is the least efficient policy, regardless of whether it is measured in regard to the industrial or export subsidy policies. The superiority related to the specific and cost ad valorem subsidies hinges upon the production technology. We can thus provide a theoretical explanation to the real world phenomenon as to why governments usually offer a specific or cost ad valorem subsidy policy to agricultural products and exports.     

Learning by Doing, Precommitment and Infant-Industry Promotion

We examine the implications for strategic trade policy of different assumptions about precommitment in a two-period Cournot oligopoly game with learning by doing. The inability of firms and governments to precommit to future actions encourages strategic behaviour which justifies an optimal first-period export tax relative to the profit-shifting benchmark of an export subsidy. In the linear case the optimal subsidy is increasing in the rate of learning with government precommitment but decreasing in it without, in apparent contradiction to the infant-industry argument. Extensions to active foreign policy, distortionary taxation and Bertrand competition are also considered.     

Biofuel Subsidies and International Trade

This paper explores optimal biofuel subsidies in a general equilibrium trade model. The focus is on the production of biofuels such as corn‐based ethanol, which diverts corn from use as food. In the small‐country case, when the tax on crude is not available as a policy option, a second‐best biofuel subsidy may or may not be positive. In the large‐country case, the twin objectives of pollution reduction and terms‐of‐trade improvement justify a combination of crude tax and biofuel subsidy for the food exporter. Finally, we show that when both nations engage in biofuel policies, the terms‐of‐trade effects encourage the Nash equilibrium subsidy to be positive (negative) for the food exporting (importing) nation.     

Free Entry, Quasi-Free Trade, and Strategic Export Policy

This paper analyzes governments' choices between strategic export subsidies and free trade as a commitment when firms are free to enter or exit in response to these choices. Entry and exit is treated as a discrete process. Within the context of a four-stage game, two types of equilibria emerge: a quasi-free-trade equilibrium in which one of the two governments commits to free trade, while the other has a Nash equilibrium subsidy that is zero and bilateral export subsidies. Concerning welfare effects, if fixed costs are large enough, both countries achieve a welfare gain relative to free trade.     

Strategic Investment Subsidies under Asymmetric Oligopoly

This paper examines strategic investment subsidies in an international oligopoly. A general oligopoly model is constructed in which firms compete in two stages and governments commit to investment subsidies prior to firms' actions. The paper considers asymmetry among firms that arises from the nature of goods they produce rather than their cost structures. When firms produce asymmetrically differentiated goods, it is found that a change in the number of foreign competitors may alter the sign of the optimal unilateral investment subsidy. An example of policy reversal is provided in the case of strategic research and development subsidies for a quality‐differentiated industry.     

Is Corporate Environmentalism Good for Domestic Welfare?

Many private firms voluntarily care about the environment and declare that their products and production processes are environmentally friendly. This paper shows that corporate environmentalism may reduce the effectiveness of government policies. A simple third‐market trade model with strategic environmental and trade policy is employed, in which an environmentally conscious domestic firm competes with a profit‐maximizing foreign firm. It is shown that even if emission taxes and export subsidies are both available, corporate environmentalism may reduce domestic welfare when pollution is transboundary. In the realistic situation where export subsidies are prohibited, welfare may fall even if pollution is local.     

Trade Policies for Exporting Industries under Free Entry

This paper computes optimal export taxes and domestic production subsidies for exporting industries under free entry. We show that domestic welfare is not at maximum, as is typically believed, when the export price is a monopoly price, and the domestic price is a competitive price, because a market structure effect has to be taken into account. Furthermore, we show that the optimal tax/subsidy formulas for an oligopoly coincide with those under perfect competition, if foreign and domestic demand functions are both linear. We also discuss optimal trade policies when only one instrument is available, and we run numerical simulations to determine and compare optimal trade taxes under endogenous and exogenous market structures.     

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。     

EXPORT SUBSIDIES VERSUS EXPORT QUOTAS WITH INCOMPLETELY INFORMED POLICY MAKERS*

This paper analyses export subsidies (price incentives) and export quotas (quantity controls) in the Brander‐Spencer (1985) model when policy makers have limited information on demand and cost structures. We examine necessary or sufficient information for policy makers to determine welfare‐enhancing policies. It is crucial that they know the elasticity value of the slope of the inverse demand curve and the market share. It is also shown that for policy makers, export quotas are superior to export subsidies under certain conditions.     

A re-analysis of the trade and welfare effects of export subsidies

This article proposes a new analysis of the market and welfare effects of export subsidies. Current analysis uses a default assumption of imports being prohibited by the exporting country. We contend that this assumption fails on several fronts: it is not consistent with the ceteris paribus assumption used in economic analysis; it is unrealistic in a world of fast-dropping transportation costs and free trade; and it hides the true effect of an export subsidy which is to create inefficient intra-industry trade. Correcting the analysis is important as, even with a proliferation of treaties, governments continue to enact policies to promote trade that may have similar effects to an export subsidy. Proceeding at a basic level, this article presents graphical analysis of export subsidies to replace the content in current undergraduate textbooks, in order to train the next generation of economists to think clearly about the effects of this policy.     

Trade policy and quality leadership in transition economies

Trade policy and quality leadership in transition economies are analyzed in a duopoly model of trade and vertical product differentiation. We first show that the incidence of trade liberalization is sensitive to whether firms in transition economies are producers of low or high quality. Second, we find that neither free trade nor the absence of a domestic subsidy are optimal: Both a tariff and a subsidy increase price competition and while the former extracts foreign rents the latter results in quality upgrading. Third, there exists a rationale for a government to commit to a socially optimal policy to induce quality leadership by the domestic firm when cost asymmetries are low. Finally, we establish an equivalence result between the effects of long-run exchange rate changes and those of trade policy on price competition (but not on social welfare).     

Specific vs Ad Valorem Strategic Export Subsidies with Taxation Distortion

This paper employs a model to compare the welfare between optimal specific and ad valorem export subsidies if the subsidy payment is financed by distortional taxation. It is found that the welfare under the specific subsidy regime is higher (lower) than that under the ad valorem subsidy regime if the social cost of taxation distortion is low (high). Moreover, the signs of the two optimal subsidies are also crucially dependent on this social cost. They are positive (negative) if the social cost is low (high).     

国际多市场寡头条件下的贸易政策和产业政策

国际多市场寡头是Bulow( 1 985)提出的多市场寡头概念在国际贸易领域的自然延伸。在本文中 ,市场之间联系的纽带是本国企业具有规模收益递减的生产技术。本文的主要结论是 ,第一 ,如果本国企业与外国企业在外国市场进行价格竞争 ,那么 ,最优干预组合包括国内生产补贴与出口税 ,它们对本国福利的作用是一致的。第二 ,如果本国企业与外国企业在外国市场进行数量竞争 ,那么 ,最优干预政策组合包括国内生产补贴与出口补贴 ,它们作用于本国福利的方向是不一致的 ,这时 ,本国政府用国内生产补贴执行反托拉斯职能 ,用出口补贴执行利润转移职能。第三 ,作为模型的一个应用 ,本文论证了出口退税政策会加剧国内市场的扭曲 ;而且它不一定能够提高本国福利。
