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.     

Trade policy and mixed enterprises

Abstract .  This paper demonstrates that the degree of state ownership affects neither the level of socially optimal activities nor welfare if the government chooses optimal trade policy instruments. In the case of rivalry in the home market, the optimal import tariff is independent of the degree of state ownership, and the optimal production subsidy decreases with state ownership if the optimal tariff is positive. For the case of Cournot rivalry in a third market, the optimal export subsidy increases with state ownership, while in the case of Bertrand rivalry with differentiated products, the optimal export tax increases with state ownership.     

Optimal Tariffs under a Revenue Constraint*

This paper examines the optimal tariff structure under a revenue constraint. When a fixed level of tax revenue has to be collected from the tariff alone, no adjustment in tariff rates can achieve an efficient resource allocation, even in a small open economy. Hence, the optimal tariff problem arises under a revenue constraint. We show that the revenue‐constrained optimal tariff structure is characterized by the following two rules: (i) the optimal tariff rate is lower for the import good that is a closer substitute for the export good, and (ii) the stronger the cross‐substitutability between imports, the closer the optimal tariff is to uniformity. This provides a theoretical explanation for the finding in empirical studies that the efficiency loss from a uniform tariff structure is negligible.     

Trade taxes and the current account

We show that, under some conditions, a temporary import tariff improves the current account, whereas a temporary export tax deteriorates it. Permanent import tariffs and export taxes have an identical, although ambiguous, effect on the current account.     

Import Protection Bias

Rodrik (1995) notes that trade regimes tend to be biased towards import protection, while the standard political economy models either yield no prediction on the bias of the trade regime or predict, counterfactually, a bias towards the export sector. This constitutes an important shortcoming in the political economy of trade literature. In this paper, the Grossman and Helpman (1994 ) “Protection for Sale” model is extended by adding government expenditure. This expenditure may be financed via a combination of tariff revenue and a distorting wage tax. In addition to the government expenditure, export subsidies need to be financed either via tariff revenue or a distorting wage tax. With this addition, plausible values of the model's parameters yield import protection bias.     

Revenue-Constrained Combination of an Optimal Tariff and Duty Drawback

A duty drawback is an export subsidy determined as a percentage of the tariffs paid on the imported inputs used in its production. This paper examines the revenue-constrained optimal tariff structure in a small open economy including a duty drawback as a trade policy tool. This paper has two main aims. First, we show that the revenue-constrained optimal combination of tariff and duty drawback for a given revenue level is not unique. Second, we show that if the optimal import tariff rates are all positive when the duty drawback rate is zero, then the optimal import tariff rates are always positive when the duty drawback is positive.     

Countervailing Duties, Foreign Export Subsidies and Import Tariffs

Given that countervailing duties and import tariffs are set in different ways and for different purposes, I re-examine the relationship between countervailing duties, foreign export subsidies and import tariffs under imperfect competition. I find that (i) the optimal countervailing duty depends on the existing import tariff level; (ii) the optimal import tariff is so high that the optimal countervailing duty is zero and hence foreign export subsidization occurs; and (iii) it is more likely for countervailing duties to be imposed on a foreign firm whose government takes no action when other foreign countries reduce or eliminate their subsidies on exports.     

Asymmetric Tax Policy Responses in Large Economies With Cross-Border Pollution

We build a model of cross-border pollution between two large open economies, one importing the polluting good and the other exporting it, and derive their non-cooperative trade and environmental tax policies. We show among other things, that (1) in response to a bilateral reduction in trade taxes by both countries, the former country’s optimal policy is to lower its Nash emissions tax while the latter’s is to raise it, and (2) in response to an increase in emissions tax rates by both countries, the former country’s optimal reaction is to raise its Nash import tariff, while the latter’s is to reduce its Nash export tax. That is, in the present context, freer trade leads the exporting country to adopt stricter while the importing country laxer environmental tax policies.     

Optimal policy for environmental goods trade in asymmetric oligopolistic eco-industries

In this paper, we examine the optimal structure of an environmental tax to pollution, a production subsidy to a domestic eco-industry, and an import tariff on environmental goods (EGs) in a two-country model where the home country imports EGs from the foreign country. Home and foreign firms that produce EGs engage in Cournot competition. We then assume that the number of the home local firms which produce EGs is constant, but that of the foreign firms is variable. Our main findings are as follows: (I) The optimal environmental tax level may be lower than the Pigouvian level even if the tax has a positive impact on the output of EGs produced by a domestic firm. (II) The optimal tariff level may be positive when the country implements the first best policy combination in a closed economy regarding the environmental tax and the subsidy. (III) The optimal subsidy level may be positive, and then the subsidy may be substitutive for the import tariff on EGs.     

A Supply and Demand Exposition of a Constitutional Tax Loophole: The Case of Tariff Symmetry

The U.S. Constitution permits import tariffs but bans export duties. Yet import taxes are de facto export taxes, just as export taxes are de facto import taxes. Access to this symmetry proposition has been limited by its illustration being in daunting analytics largely restricted to international economics. This is unfortunate. Tariff symmetry exposes a tax loophole of constitutional proportions, a case where economics trumps the intentions of America's Founding Fathers. Moreover, tariff revenue was the U.S. government's pivotal revenue source from 1789 until the 1913 constitutional sanctioning of the income tax. Because U.S. exports were heavily agricultural, tariff symmetry implies that federal taxation had an export dimension with disparate economic and regional consequences. By making tariff symmetry more accessible, this paper lowers the cost of examining important issues.     

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。     

Welfare‐improving Coordinated Tariff and Sales Tax Reforms under Imperfect Competition

This paper studies the welfare effects of coordinated domestic sales tax reform associated with a reduction of the import tariff under imperfect competition. We set up a simple oligopoly trading model where domestic and exporting firms compete in the home market. We show that, if the initial levels of import tariff and sales tax are positive, there always exist welfare‐improving sales tax reforms. In some cases, a reduction of the sales tax accompanied by a reduction of the import tariff increases social welfare, whereas in other cases, raising the sales tax can increase social welfare.     

Trade Liberalization in the Presence of Foreign Direct Investment and Tax Credits: Estimates for Costa Rica

The paper uses a calibrated general-equilibrium model to quantify the welfare impact of trade liberalization—and compute the optimal tariff structure—for Costa Rica when trade-policy-induced foreign direct investment and international capital taxation with credits are present. It shows that complete trade liberalization reduces Costa Rica's welfare, as it leads to an outflow of capital and loss of tax revenue which more than offset the efficiency gains from an enhanced resource allocation. The optimal tariff structure for the Costa Rican economy turns out to be a mixture of relatively small import tariffs and subsidies.     

US Ethanol Trade Policy: Pollution Reduction or Domestic Protection

To mitigate dependence on fossil fuel and reduce pollution, the US government has undertaken several policies—an import tariff, tax credit, and mandate—to augment domestic ethanol production and increase ethanol in the fuel supply. This study uses a general equilibrium model to analyze the effects of the US ethanol import tariff on welfare by internalizing the externality and incorporating US fuel and ethanol policies and to determine the optimal tariff. The results show that because of the environmental benefits of imported ethanol, the adverse effects of domestic ethanol on the environment, the need for the imported ethanol to boost the blended gasoline production, and the economy‐wide interactions of various markets, the optimal trade policy may call for subsidizing rather than taxing ethanol imports.     

TARIFFS AND IMPORTS MISINVOICING UNDER OLIGOPOLY

Mismatch of trade statistics between developed and developing countries indicate a substantial misinvoicing of trade figures, primarily by developing country traders. This is due to the inflexible exchange rate regimes, severe import restrictions and export subsidies prevailing in Less Developed Countries (LDCs). In this paper, we focus on import underinvoicing due to high tariff barriers in a market where domestic producers compete with importers. Specifically, we examine how tariff levels, market structure and government intervention (in the form of intensity of monitoring and severity of penalties) affect the levels of underinvoicing. We also look at the optimal levels of import tariff and instruments of government intervention in these circumstances.     

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。     

A Partial Equilibrium Analysis of Trade with Decreasing Transport Costs

Decreasing transport costs are incorporated in the standard partial equilibrium analysis of trade by allowing the divergence—introduced by transport costs—between export and import price to decrease with the volume of trade. When the excess demand (supply) curve is steeper than the long run average cost curve for imports (exports), we observe that an import (export) tariff raises (lowers) the domestic price by an amount exceeding the tariff. Further, when the excess demand (Supply) curve is less steep than the long run average cost curve for imports (exports), the possibility exists that an import (export) tariff may lower (raise) the domestic price. These results lead to the important conclusion that tariffs cannot be used as measures of nominal protection across industries. [F10]     

Endogenous Timing in a Strategic Trade Policy Game: A Two-Country Oligopoly Model with Multiple Firms

This paper examines strategic trade policy games where the number of firms in the importing and exporting countries differs and all firms play as Cournot oligopolies. Under the assumption of linear demand and constant marginal cost, we show that, if the number of firms in the exporting country exceeds that in the importing country by more than three, the government of the exporting country chooses to move as a leader, imposing an export tax on firms. The government of the importing country then becomes a follower and imposes an import tariff. This lies contrary to the previous study, which assumed that there is only one firm in each country.     

Measuring China’s trade liberalization: A generalized measure of trade restrictiveness index

Neither simple average nor import-weighted average tariff indexes are ideal measures of tariff barriers. In this paper, we propose a generalized trade restrictiveness index (GTRI) that extends Feenstra’s (1995) tariff restrictiveness index (TRI) by relaxing the crucial assumption of a small open economy. We show that the GTRI can be measured using import tariffs, import shares, and the corresponding import and foreign export elasticities. We then apply the GTRI to examine how trade restrictiveness has evolved in China from 1997 to 2008, the period in which China entered the WTO. The GTRI indicates a higher level of protection than simple and import-weighted averages, but lower than the TRI. We further show a negative correlation between tariffs and product export supply elasticity, indicating that strategic trade policy was being pursued prior to China’s WTO accession. Finally, we calculate the welfare loss and terms-of-trade gain due to tariff protection. The overall tariff pass-through increases from around 28% to almost 47% because of the WTO.     

Strategic interoperability standards and trade taxes

In a two-country international trade framework, the paper considers the interplay between the governments' incentives for conducting traditional trade policies and their incentives for the policies toward compatibility between the products of the firms competing in the international market. The model assumes that one domestic and one foreign firm supply partially incompatible products for the home country market while consumers value both variety and a network externality. Motivated by the benefits of the network externality, the home government sets a standard requiring the foreign firm to guarantee a minimum level of compatibility between its own product and the product of the domestic rival. The paper analyzes the home country standard setting and import tariff policies as well as the incentives of the foreign country for imposing the export tax and conducting a policy which enhances the degree of compatibility between the rival products in the export market.
