Tariffs and the adoption of clean technology under asymmetric information

Abstract.  This paper examines the effect of a tariff on the decision of a foreign monopolist to adopt 'clean' technology, which reduces the flow of a negative cross-border externality. The clean technology increases the marginal cost of production relative to the dirty technology, but only the firm knows the extent of the increase. Under complete information, despite its protectionist motivation, the importing country's optimal tariff induces the firm to adopt the clean technology if and only if it is globally efficient to do so. Under incomplete information, this efficiency property is disrupted, and the firm biases its choice in favour of dirty technology. JEL classification: F13, F18     

Tariff Policy and the Foreign Entry Decision in the Presence of a Cost-Based Informational Asymmetry

The paper demonstrates that the standard prediction on the relation between tariff rates and the mode of foreign entry—exports or direct investment—may not hold in the presence of incomplete information. A foreign firm lacks full information on the cost structure of an informed incumbent firm located in the domestic (potential) host country. Within a two‐period model, the local incumbent may behave in a manner which keeps the potential foreign entrant uninformed of its cost structure. In such a pooling equilibrium, the uninformed foreign firm either refrains from entering altogether or serves the host country via exports at tariff rates which would, otherwise under complete information, induce entry via direct investment. When entry mode is altered, other standard full‐information effects of trade policy may also no longer hold.     

Tax competition for foreign direct investments and the nature of the incumbent firm

We investigate tax/subsidy competition for foreign direct investments (FDI) between countries of different size when a domestic firm is the incumbent in the largest market and we study how the nature (public or private) of the incumbent firm affects policy competition. We show that, differently from the case of a private firm, the country hosting the incumbent always benefits from FDI if the domestic firm is a public welfare‐maximizing firm. We also show that the public firm acts as a disciplinary device for the foreign multinational that will always choose the efficient welfare‐maximizing location. An efficiency‐enhancing role of policy competition may then arise only when the domestic incumbent is a private firm, whereas tax competition is always wasteful in the presence of a public firm.     

Ranking the optimum tariff and the maximum revenue tariff in vertically related markets

This paper firstly shows that in a vertically related industry with either domestic upstream monopolist or foreign upstream monopolist, when the upstream firm adopts uniform input pricing, the optimum-welfare tariff is higher than the maximum-revenue tariff, if the number of foreign competitors is sufficiently large. Secondly, when domestic upstream monopolist adopts discriminatory input pricing, the maximum-revenue tariff is higher than the optimum-welfare tariff. Thirdly, when foreign upstream monopolist adopts discriminatory input pricing, the optimum-welfare tariff will exceed the maximum-revenue tariff if the sizes of domestic and foreign firms become more unequally distributed.     

Protecting consumers through protection: The role of tariff-induced technology transfer

We consider a duopolistic trade model where a tariff induces the foreign firm to transfer its superior technology to the domestic rival. Contrary to the conventional wisdom, such a tariff raises consumers’ surplus relative to the free trade situation. We characterize the optimal tariff with and without precommitment on the part of the local government. Possibility of technology transfer reduces the optimal tariff rate compared to the no-transfer situation.     

Environmental regulation and technology transfers

This paper analyzes the situation in which a national government introduces environmental regulations. Within the framework of an international duopoly with environmental regulations, an environmental tax imposed by the government in the home country can induce a foreign firm with advanced abatement technology to license it to a domestic firm without this technology. Furthermore, when the domestic firm's production technology is less efficient than that of the foreign firm, the foreign firm may freely reveal its technology to the domestic firm. These improvements through the voluntary transfer of technology imply that environmental regulations have positive impacts on innovation.     

Multinational Corporations, Stackelberg Leadership, and Tariff-jumping

In this paper we consider the traditional entry mode choice of an incumbent monopolist facing entry by a single foreign firm. By allowing entry to be either via exporting or foreign direct investment and for the possibility of Stackelberg equilibria where firms can set quantities in one of two time periods, namely “early” or “late,” we find conditions where both Cournot and Stackelberg equilibria emerge endogenously. Furthermore, by introducing a simple linear tariff, we see that it not only affects the choice of exporting and FDI in a nonlinear way, but that it can also affect the type of equilibrium that emerges.     

Location choice under trade and environmental policies

In this paper, we use a game theoretic model to analyze the trade-off between the attractiveness of FDI and the environmental damage caused by production under asymmetric information. In the first stage, the domestic developing country reveals the level of import tariff and pollution tax under information uncertainty about the environmental damage that the foreign firm can cause. The foreign firm from a developed country decides where to locate afterwards with complete information about its own damage. Results show that the developing country can be better off encouraging FDI if and only if the marginal damage of pollution is sufficiently low. The optimal level of pollution taxes attracting FDI is higher than the marginal damage of pollution. However, the optimal pollution tax without FDI can be lower than the marginal damage of pollution with sufficiently high demand in the developing country.     

Natural monopoly and differential pricing

Under uniform pricing a monopolist cannot make a positive profit in equilibrium. I analyze how differential pricing can be exploited by a natural monopolist to deter entry when entry is costless. In a two-stage game with price competition before quantity competition I show that the incumbent firm can deter entry and make a positive profit in equilibrium. The incumbent sets two different prices, the low price to deter entry and the high price to generate profit. Entry is not possible because of scale effects. If dumping is allowed for all firms no positive profits are realizable, but welfare is reduced. I show that for some parameter values the incumbent is forced to engage in a stunt (i.e., set a negative low price) to keep entrants out.     

MULTINATIONALS,TAX HOLIDAYS,AND TECHNOLOGY TRANSFER*

Host country governments often grant investment incentives to foreign firms located in their territories. We show that such preferential treatment of foreign firms can induce transfer of foreign technology, facilitate entry by the local firm, and improve host country welfare. However, this pro‐competitive outcome results when preferential treatment is granted for a limited time. Permanent tax concessions yield the opposite effect.     

OPTIMUM-WELFARE AND MAXIMUM-REVENUE TARIFFS IN MIXED OLIGOPOLY WITH FOREIGN COMPETITORS

This paper re-examines the important tariff ranking issue under a linear mixed oligopoly model with foreign competitors and asymmetric costs. We demonstrate that under Cournot competition, when the size of domestic private and foreign private firms become more unequally distributed, optimum-welfare tariff will exceed maximum-revenue tariff. We also show that under Stackelberg competition, when the domestic government protects its domestic sector, it will levy higher optimum-welfare tariffs versus maximum-revenue tariffs; however, when it decides to open its doors more for foreign competitors, it will need to levy higher maximum-revenue tariffs versus optimum-welfare tariffs. The above results remain valid whether the domestic public firm acts as a leader or a follower.     

Market Size,Local Sourcing and Policy Competition for Foreign Direct Investment

This paper analyzes policy competition for a foreign‐owned monopolist firm between two asymmetric countries. In particular, one country has a larger economy than the other country. At the same time, the small country produces an intermediate good for the final good production, while the large country does not. We show that whether a country will win foreign direct investment (FDI) competition is determined by the interaction between relative transport costs of intermediate and final goods and the market size of the large country relative to that of the small country; and policy competition for FDI may Pareto weakly improve national welfare of the competing countries.     

Tariff induced licensing contracts,consumers’ surplus and welfare

We construct a duopolistic trade model with technology transfer and consider two-part tariff licensing contracts. We show that a tariff on foreign products can influence the licensing strategy of the foreign firm. There is a trade-off between a tariff and a royalty license in affecting the product price. We show in particular that a tariff can be chosen so as to induce fee licensing and maximize both consumers’ surplus and domestic welfare. This resolves the so-called conflict between these two objectives in respect of the choice of a tariff. The paper provides a number of testable hypothesis.     

Welfare effects of competition for FDI between technologically asymmetric countries with varying trade costs

Given the traditional argument that host countries' excessive competition for FDI (foreign direct investment) deteriorates the host countries' welfare, this paper examines the impact of policy competition for FDI on social welfare considering varying trade costs. Based on a model where two technologically asymmetric countries compete for FDI, we determine an equilibrium where a multinational firm relocates to a less efficient country. Moreover, we demonstrate that the policy competition for FDI between less integrated economies might improve social welfare when the multinational firm relocates to a country with a lower technology and a less competitive market. Nonetheless, we show that the traditional argument can be true when the policy competition for FDI between highly integrated economies deteriorates host countries' welfare, as supported by the empirical evidences of moderated competition for FDI within EU member countries.     

Technical compatibility and the mode of foreign entry with network externalities

Abstract.  We examine the preferences of a foreign firm and a local government over two modes of foreign direct investment: de novo entry and acquisition of the domestic incumbent. Two crucial features of the model are network externalities and partial incompatibility between the domestic and the foreign technology. The relative welfare impact of the two entry modes depends on the degree of market competition and the strength of the network externality. The clash between the foreign firm's choice and the local government's ranking of the two entry modes can motivate limits on the degree of foreign ownership of the local firm.     

TARIFF JUMPING FOREIGN DIRECT INVESTMENT DECISION IN A QUALITY‐DIFFERENTIATED MARKET

Using a product differentiation model, this paper discusses the issue of transnational firms evading tariffs and investing directly in a host country (through foreign direct investment (FDI)). Where product quality is differentiated between foreign and host country firms and assuming a firm's quality requirement is a long‐term strategy and is not affected by a foreign firm's trade decision, we obtain the following findings. First, whether or not a host country firm produces high or low quality products, raising the quality requirement for foreign products will increase the possibility of a foreign firm choosing FDI instead of exporting a product to the host country. Second, raising the quality requirement for domestic products will lower the possibility of foreign firms choosing FDI without regard to the product's quality. Finally, given a competitor in the host country, in FDI, a foreign high‐quality product‐producing firm has an advantage over a low‐quality product‐producing firm. We also find that even when firms' quality decisions are affected by a foreign firm's trade decision, most of the above results will still hold.     

Host country's strategic policies and multinational firm's choice of entry mode

This paper examines the effects of contract enforceability and market structure on a firm's choice between licensing and foreign direct investment. Clearly, the firm's choice impacts upon social welfare in the host country. Therefore, the government of the host country is likely to set contract enforceability for inducing the multinational firm (MNF) to choose a desirable mode of entry. The paper takes into account two different cases. In the first case, the host country does not have an incumbent that can compete with the MNF, and in the second case, it has one incumbent that can compete. The paper shows that the government's choice of contract enforceability is crucially dependent upon the domestic market structure and the domestic capacity to absorb the advanced technology of the MNF.     

Strategic competition and optimal parallel import policy

Abstract In a two‐country Hotelling type duopoly model of price competition, we show that parallel import (PI) policy can act as an instrument of strategic trade policy. The home firm’s profit is higher when it cannot price discriminate internationally if and only if the foreign market is sufficiently bigger than the domestic one. The key mechanism in the model is that the home firm’s incentive to keep its domestic price close to the optimal monopoly price affects its behavior during price competition abroad. We also analyze the welfare implications of PI policies and show that our key insights extend to quantity competition.     

Technological innovation and multinational expansion: A two-way link?

The paper examines how investment in research influences the form of foreign expansion chosen by the firm, and vice versa. We consider a two-country model where a monopolist producing in one country can choose between export and foreign direct investment. We assume process innovation, where the cost-reducing technological innovations are an outcome of the firm's investment in R&D. The role of technology transfer costs is explored. The model shows that, with low costs of technology transfer, there is a two-way link between the firm's R&D effort and multinational expansion. We also prove that both the research choice and the multinational choice have a positive effect on consumers' welfare in both countries.     

Vertical technology transfer and the welfare implications of patent protection

Significant amount of vertical technology transfer occurs between developed and developing-country firms, and many trading companies from developing countries create competition in the developed countries, yet the literature on intellectual property rights did not pay considerable attention to these aspects. In a Cournot oligopoly with vertical technology transfer, we show that patent protection in the developing country raises developed-country welfare if the following three conditions hold together: (i) patent protection in the developing country deters entry in the final goods market, (ii) the marginal cost difference between the incumbent and the entrant final goods sellers is sufficiently small, and (iii) the marginal cost difference between the incumbent and the entrant developing-country producers is sufficiently high. We also show that patent protection in the developing country always creates higher developing-country welfare if no developing-country firm enters the final goods market. We also discuss the implications of Bertrand competition on our results.
