Mergers and Trade Policy under Oligopoly

For an oligopolistic industry, the effects of mergers on the domestic country's optimal trade policy are analyzed. If the domestic country pursues an optimal trade policy then it will always lose as a result of a foreign merger. The optimal domestic response to a foreign merger is to decrease (increase) the tariff if demand is concave (convex) and to increase the production subsidy. The foreign merger reduces foreign welfare when the domestic country pursues its optimal trade policy. The optimal domestic response to a domestic merger is to leave the tariff unchanged and to increase the production subsidy.     

Foreign direct investment subsidy in a dynamic stochastic general equilibrium model with heterogeneous firms

This study analyzes the macroeconomic impacts of subsidies to attract multinational corporations when firms are determining whether to enter or how to serve foreign markets. We show that a small FDI subsidy scheme induces consumption gains and delivers short‐term welfare improvement for the FDI host country if firms differ in productivity. However, the subsidy generates a new problem and results in the wealth reallocation effect, leading to welfare deterioration for the host country in the long run. Moreover, we find that a subsidy program induces a welfare improvement for the host country if it is offered to all domestic producers instead of foreign producers only in the host country.     

FDI Policy,Greenfield Investment and Cross‐border Mergers

This paper examines a multinational's choice between greenfield investment and cross‐border merger when it enters another country via foreign direct investment (FDI) and faces the host country's FDI policy. Greenfield investment incurs a fixed plant setup cost, whereas the foreign firm obtains only a share of the joint profit from a cross‐border merger under the restriction of the FDI policy. This trade‐off is affected by market demand, cost differential, and market competition, among other things. The host country's government chooses its FDI policy to affect (or alter) the multinational's entry mode to achieve the maximum social welfare for the domestic country. We characterize the conditions shaping the optimal FDI policy and offer intuitions on FDI patterns in developing and developed countries.     

Restrictions on Foreign Investments and the Relocation of Firms

We analyse why the Chinese government sets restrictions on foreign direct investment (FDI). We focus our analysis on the percentage of shares in relocated firms that the government allows to be foreign‐owned. The government's decision on this percentage depends on the entry cost, the number of firms that relocate and the weight of the consumer surplus in the objective function of the government. We show that by its choice of this percentage, the Chinese government may restrict or encourage FDI to its country. We also find that if the government may subsidise the fixed entry cost, it provides a subsidy only when the producer surplus has a greater weight than the consumer surplus in weighted welfare. In that case, the subsidy encourages relocation by both firms and permits the government to allow a lower percentage of shares to be foreign‐owned in relocated firms.     

The merger paradox in a mixed oligopoly

This paper examines the set of surplus maximizing mergers in a model of mixed oligopoly. The presence of a welfare maximizing public firm reduces the set of mergers for which two private firms can profitably merge. When a public firm and private firm merge, the changes in welfare and profit depend on the resulting extent of private ownership in the newly merged firm. When the government sets that share to maximize post merger welfare as assumed in the privatization literature, the merger paradox will often remain and the merger will not take place. Yet, we show there always exists scope for mergers that increase profit and increase (if not maximize) welfare. Interestingly, these mergers often include complete privatization.     

Trade Liberalization and the Profitability of Domestic Mergers

It is often thought that a tariff reduction, by opening‐up the domestic market to foreign firms, should lessen the need for a policy aimed at discouraging domestic mergers. This implicitly assumes that the tariff in question is sufficiently high to prevent foreign firms from selling in the domestic market. However, not all tariffs are prohibitive, so that foreign firms may be present in the domestic market before it is abolished. Furthermore, even if the tariff is prohibitive, a merger of domestic firms may render it nonprohibitive, thus inviting foreign firms to penetrate the domestic market. Using a simple example, the authors show that, in the latter two cases, abolishing the tariff may in fact make the domestic merger more profitable. Hence trade liberalization will not necessarily reduce the profitability of domestic mergers.     

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.     

Local content requirement on foreign direct investment under exchange rate volatility

This paper analyzes the effects of exchange rate volatility of both the host country and the parent country on host-government policy related to local content requirement (LCR) on export-oriented foreign direct investment (FDI) in the context of an oligopolistic market in a third country. We, inter alia, find that an increase in the volatility foreign exchange rate decreases optimal LCR both under free entry and exit of foreign firms and when the number of foreign firms is fixed. We also find that the government uses a less strict LCR policy when the number of foreign firms is endogenous than when it is exogenous.     

Foreign direct investment,international trade,and firm heterogeneity

We present an asymmetric model with firm heterogeneity and foreign direct investment (FDI) from a developed country to a developing country. We found that the successful entry firms could be sorted from highest to lowest according to productivity as reimport firms, FDI firms, export firms, and domestic firms. We also found that FDI decreases (increases) the gross national income of the developed (developing) country, but it can either increase or decrease the world income according to the level of the relative propensity to spend. In addition, we demonstrated that FDI influences welfare through variations in average price, national income, and the number of types of goods.     

Horizontal Mergers in a Liberalizing World Economy

This paper is concerned with the effect of horizontal mergers in an open economy environment. It is found that, with the presence of economies of scale and imperfect competition, a domestic merger may bring about an additional gain to the country in that it shifts profit from foreign to domestic firms. Consequently, the condition on the degree of economies of scale for permitting domestic horizontal mergers would be weaker under an open economy than under a closed economy. Furthermore, the analysis shows that such mergers can also raise foreign welfare. Finally, the model is used to discuss the need to coordinate merger policies among trading partners in tandem with trade liberalization.     

海外市场需求与跨国垂直并购——基于低端下游企业的视角

本文构建了一个产品从低端到高端分布的Hotelling模型,以探讨我国低端下游企业进行跨国垂直并购的时机选择和决定因素。研究表明,垂直并购国外高端上游企业能实现扩大市场份额、提升产品定位的双重效能。海外市场需求环境对低端下游企业拓展战略起关键性作用。在正常需求条件下,与直接出口及先并购国内上游企业再出口两种模式相比,跨国垂直并购并非最优选择。在遭受负向需求冲击时,国外上游企业生产成本的大幅上升以及国外下游竞争对手品牌价值的下降给跨国垂直并购带来了契机,此时在技术密集度较高的上游产业进行跨国垂直并购成为国内低端下游企业的最优选择。如果并购能实现足够大的品牌价值效应,还会改善被并购企业所在国的社会福利水平。     

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.     

外商技术转移、创新激励与东道国引资政策——走自主创新道路,我们能依靠外国技术吗？

文章在累积创新框架下建立一个附加拍卖的动态博弈模型,研究东道国企业利用外商技术转移实现技术升级的微观机制,以及东道国政府旨在改善社会福利的引资政策。研究后发现:对于核心技术,外商总有激励进行技术封锁;对于一般技术,外商愿意将其技术许可给东道国以赚取垄断利润;东道国企业只有坚持自主创新才能获得技术模仿的机会并最终突破外商对核心技术的封锁;若东道国政府能使外商将核心技术授权给本国企业,本国企业将绕过自主创新从而直接进行模仿创新,若不能有效控制外商技术转移方式但可对仅转移设备等"硬"核心技术的方式采取有效限制,可降低潜在技术模仿成本从而减少东道国激励本国厂商进行创新的补贴成本。最后,文章讨论了我国利用外资推动技术升级的方式。     

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.     

On Mergers and Agglomeration

We formulate a model of mergers and acquisitions assuming a monopolistic competitive industry that exhibits agglomeration economies. We provide the conditions for the existence of a non‐trivial Nash equilibrium in the acquisition market at which the most productive firm acquires a range of less‐productive firms. Most importantly, we show that domestic merger and acquisition activities are international trade promotionary. We also show that such types of mergers and acquisition will improve the competitive position of foreign firms leading to an increase in their market share. In addition, domestic mergers and acquisitions will increase the number of imported varieties.     

Lobbying, corruption and “optimal” tariff

This paper explores how a government officer enacts “optimum” import policy when confronting lobbies on trade policies from both domestic and foreign firms in a transition economy. Two results are found: firstly, if the inducement from the foreign firm on the government officer works, then the optimum tariff is negative, that is, import subsidy. However, this subsidy will turn to a positive tariff rate with the increasing lobbying inducement from domestic firms. Secondly, zero tariff duty is not an optimum choice under most circumstances. Besides, an asymmetric result is that when these two firms’ marginal costs are different, the optimum policy is to levy an import tariff on the one whose marginal cost is relatively small, while the other firm will get an import subsidy.     

The impact of multinational entry on domestic market structure and investment

We model the impact of different modes of multinational entry on the choices of domestic firms. Focusing on the competitive effects of foreign entry for the host country we demonstrate that greenfield investment will increase competition only if it is not countered by anti-competitive reactions on the part of the domestic firms. Together with cross-border mergers and acquisitions the model, thus, provides two alternative explanations for the increase in concentration ratios in industries with mostly horizontal foreign direct investment. Moreover, foreign presence is shown to raise total investment in the local industry at the cost of crowding out domestic investment.     

THE NUMBER OF FIRMS AND THE POLITICS OF STRATEGIC TRADE POLICY

Incorporating home firms' lobbying in a country into a third market model of oligopoly, this paper studies how such lobbying affects the government's strategic export policy scheme. We pay special attention to the home firms' lobby formation and its effect on domestic welfare. The home firms can organize a lobby more easily when the number of their rival foreign firms is larger than that of them, and/or when the government is overly concerned with political contribution relative to domestic welfare. The strategic export policy under lobbying cannot improve the domestic welfare, which depends on the number of firms, the government's concern about political donation and the level of socially wasted lobbying costs.     

National champions and globalization

Abstract .  In this paper, we offer an explanation why globalization (falling trade costs) may increase the government incentive to block foreign takeover of domestic firms and increase its incentive to allow mergers among national firms. This creation of 'national champions' occurs not only because the government may have a bias against foreign takeover, but also because consumer welfare gains associated with foreign acquisitions decrease with globalization. Endogenizing the government bias through lobbying efforts of the domestic firms, the paper shows that the bias does not need to be very strong before the government promotes domestic champions provided that barriers to trade are low.     

Training and Technology Transfer

This paper analyses technology transfer from a multinational corporation (MNC) to a developing economy via training of local workers by the MNC. The paper analyses the determinants of the level of training by the MNC assuming a local entrant can subsequently hire MNC–trained workers and compete with the MNC. It is shown that a small training subsidy paid by the host government may cause the MNC to switch from entry–deterring behaviour to entry–accommodating behaviour. Such a subsidy will cause an increase in the number of skilled workers but may increase or decrease the domestic welfare of the developing country.
