Trade Policy in the Presence of Technology Licensing*

We consider strategic trade policy when a high‐cost and a low‐cost firm belonging to two different countries compete in quantities in a third country, and technology is transferable via licensing. We characterize the effects of subsidies on (i) licensing payments—a new source of rents, (ii) the decision to license, and (iii) the subsidy bill difference (compared to when licensing is infeasible). We find that, in the presence of licensing, optimal strategic trade policy has several interesting features. For example, even under Cournot competition, optimal policy can be an export tax instead of an export subsidy. Also, unlike results in strategic trade policy with asymmetric costs, we find that optimal export subsidies are not necessarily positively related to the cost‐competitiveness of firms. In other words, governments need not necessarily favor “winners” when licensing is possible. Furthermore, there exist parameterizations such that a government, if it can, might ban licensing.     

Second-best trade policies in Cournot oligopoly

In this paper we study the optimal import policy in an oligopolistic market with a given number of quantity-setting firms. In the absence of fixed costs, we show that if the policy instrument is an import quota, the optimal policy is either free trade or autarky, while if the instrument is a tariff the optimal policy is neither free trade nor autarky. In the case of fixed costs, we show that contrary to the traditional protectionist argument, a restrictive import policy might increase domestic welfare by increasing domestic consumers' surplus, instead of increasing domestic profits.     

出口退税是一项稳健的贸易政策吗?

出口退税作为一项被WTO允许的政策工具,为许多国家的政府所使用。本文在一个国际多市场寡头模型之中,研究出口退税的稳健性。主要结论如下:(1)如果本国政府的目标是最大化国家福利,那么,出口退税不是一项稳健的贸易政策;(2)如果本国政府关心收入分配,对于国家福利的不同组成部分赋予不同的权重,那么,如果政府过于关注本国企业利润,而不是本国消费者剩余和出口退税成本,出口退税就会成为一项稳健的贸易政策;(3)本国政府过于关注本国企业利润的一个可能原因是,本国企业可以通过政治捐献去游说政府,制定对于自己有利的政策。那么,如果相对于国家福利而言,政府过于关注政治捐献,出口退税就会成为一项稳健的贸易政策。     

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.     

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.     

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.     

Strategic Trade Policy and Vertical Structure

We introduce intermediaries into the Brander-Spencer model of strategic trade policy. A key finding is that in regimes involving independent retailers, output competition and linear pricing (and two-part tariffs under certain restrictions), the optimal policy involves an export tax instead of a subsidy. If firms commit to vertical structure before governments commit to policy then under output competition firms choose integration, whereas if policy precedes structure then at least one firm chooses separation. Under price competition separation is a dominant strategy regardless of whether the structure decision is made before or after the policy decision.     

International Trade Policy towards Monopoly and Oligopoly*

This paper highlights the importance of product differentiation and endogenous R&D in determining the optimal R&D policy, in a model where investment in cost‐reducing R&D is committed before firms compete in a differentiated‐goods third‐country export market. R&D is always taxed in oligopolies for high degrees of product differentiation. For lower degrees of product differentiation the duopoly is subsidized or the government remains inactive. In contrast, the monopoly is always subsidized. The government with a duopoly may be active or inactive depending on the degree of product differentiation. Thus, we may observe a reversal in the sign of the optimal R&D policy if the degree of product differentiation changes or, alternatively, if there is a change in the number of firms. Similar qualitative results hold if trade policy uses output subsidies, instead of R&D promotion.     

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.     

A Simple Model of Corporate Bailouts in a Globalized Economy*

In this paper, we explore how globalization influences the decision of governments to rescue inefficient domestic firms when bailouts affect firms’ markup. We develop a model of international trade in which immobile domestic-owned enterprises (DOEs) compete with foreign-owned enterprises (FOEs) in an oligopolistic market. The decision to bail out DOEs leads to lower corporate tax revenues if FOEs are immobile, whereas tax revenues might increase if FOEs are mobile. Interestingly, the mobility of FOEs makes governments more prone to rescuing inefficient domestic firms because tax competition reduces the opportunity cost of a bailout policy in terms of public good provision.     

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.     

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.     

Environmental Protection in the Presence of Unemployment and Common Resources

This paper examines the effects of an export tax (on a processed resource good), the number of harvesters and an afforestation policy in a small, open economy with urban unemployment. The export tax increases the urban unemployment rate, but improves the quality of the environment. Here, the optimal export tax is lower than the adjusted marginal environmental damage. Reducing the number of harvesters has a similar resource allocation effect to that of an export tax. However, the afforestation policy can resolve the trade‐off between urban unemployment and the quality of the environment and may also improve the welfare of a country.     

IS AN EXPORT SUBSIDY A ROBUST TRADE POLICY RECOMMENDATION TOWARD A UNIONIZED DUOPOLY?

Brander and Spencer (1988) and Bandyopadhyay et al. (2000) imply that the robust trade policy recommendation toward a unionized duopoly is an export subsidy. In this paper, we show that we cannot get such a result even in the linear case if the opportunity cost of public funds is sufficiently high. However, if we consider the case where the domestic firm and the trade union lobby the government to set favorable trade policies by giving the government political contributions, then the result of robustness will be restored if the government cares about political contributions sufficiently relative to national welfare.     

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。     

The Finnish Corporate Income Tax Reform and the Financial Strategy of Firms: A General Equilibrium Approach

This paper simulates the effects of the recent Finnish corporate tax reform with a computable general equilibrium model. It shows that the impact of the reform on the capital stock depends on the reactions of firms. If the financial strategy is changed to prefer dividend distribution and share issues, the cost of capital falls and the capital stock increases. On the other hand, if the criterion of financial policy is to minimise the welfare loss of current shareholders, the earlier financial behaviour should be continued. In that case,the induced higher cost of capital leads to a lower capital stock. The overall welfare evaluation of the tax reform is not sensitive to the regime shift: the reform should not have been implemented. This is because the increase in interest income taxation distorts saving decisions, expands the net foreign debt of the economy and weakens the terms of trade.     

Symbiotic Production and Optimal Export Policy

This paper constructs a two‐country trade model to examine the optimal policies relating to the export of final and intermediate products under Cournot as well as Bertrand competition when firms engage in symbiotic production internationally. The paper shows that given linear demand for the final product, the optimal export policies are to tax the exports of both the final and intermediate goods under symbiotic production, regardless of whether firms engage in Cournot or Bertrand competition in the final good market, which is contrary to the conventional wisdom.     

Buyer and Seller Concentration in Global Commodity Markets

In recent years there has been an increased incidence of export restrictions applied by developing countries to commodities and raw materials. Commodity markets may be characterized by concentration on the buyer side, with a small number of transnational intermediary firms purchasing from supplying countries and distributing to the market, and recent work has suggested that export taxes may be an optimal policy to recapture monopsony rent. However, in many commodity markets there are also a limited number of large supplying countries. This paper considers a situation where an oligopsonistic intermediary industry purchases from a small number of supplying countries, the governments of which act strategically in their policy choices both with respect to the intermediaries and any competing suppliers. In the resulting two‐stage game, the paper shows that an export subsidy, rather than an export tax, may arise as the optimal intervention.     

Taxation of firms with unknown mobility

We analyze optimal business tax policy when some firms are able to escape taxation by moving abroad. In contrast to the existing literature, we assume that the true number of mobile firms is ex ante unknown. While the government may learn from the firms' location responses to past tax rate changes, firms may anticipate this and adjust their choices accordingly. We find that incomplete information on mobility substantially affects the properties and the implications of equilibrium policy choices. First, the government may find it optimal to set a tax rate that triggers partial firm migration but full revelation of the true number of mobile firms. Second, we show that, if the firms' outside option is attractive (i.e., relocation cost and foreign tax rates are low), expected tax rates and expected firm migration are higher if the degree of mobility is unknown. Third, there is a positive value of learning, i.e., commitment on future tax rates cannot increase the government's expected revenue. However, if the government can commit to a rule‐based learning mechanism, i.e., credibly tie its future tax policy to present policy outcomes, it may obtain a Pareto improvement.     

Open-access renewable resources and pollution: Trade and policy implications in a two-country model

We examine the interaction between the relative inter-industry pollution externality and resource stock externality of harvesting in deciding trade patterns and welfare gains from trade in a two-country model (less-developed countries) with renewable resources in the absence of resource management. This paper focuses on the impacts of trade policies on resource conservation and welfare outcomes in two countries with different environmental management regimes. Differences in pollution management standards between both countries determine the direction of trade flow and gains from trade in a diversified production case. The country with a lower pollution intensity parameter, an exporter of resource goods, certainly experiences welfare loss in the post-trade steady-state and may also suffer a decline in utility throughout the transition path. However, a country with higher pollution intensity and importers of resource goods tend to gain from trade. Under national open-access resources, given that pollution is regulated up to a certain point in both countries, this study finds that implementing better restrictions on only one externality factor is not optimal from a post-trade welfare perspective. Lastly, from the point of view of policy suggestion, this paper offers an optimal trade policy that the economic and environmental effects of enforcing import tax on resource goods are likely to be Pareto-improving consequences compared to the implications of using an export tax.
