Corporate Social Responsibility and International Competition: A Welfare Analysis

This paper examines the welfare implications of corporate social responsibility (CSR) in international markets under imperfect competition. Based on a stylized model of an import‐competing duopolistic market, we show the feasibility of moving toward tariff reductions when both domestic and foreign firms launch CSR initiatives in that their payoffs include not only individual profits, but also the benefits of consumers. For the case where the foreign exporter unilaterally adopts the consumer‐oriented CSR as a strategy, there is a rent‐shifting effect because the foreign firm's payoff increases whereas the domestic firm's profit decreases. In response, the importing country's government raises its tariff on the foreign product. If, instead, the domestic firm adopts the CSR strategy unilaterally, the rent‐shifting effect disappears and both the competing firms’ payoffs increase. We further identify the conditions under which the CSR initiatives of the firms constitute the dominant strategy, leading to a Pareto efficient outcome at which the firms’ payoffs, consumer surplus, and social welfare are at their maximum levels.     

Welfare Effects of Reducing Home Bias in Government Procurements: A Dynamic Contest Model

This paper models an international contest for government procurement as a dynamic game between a domestic firm and a foreign firm. We show that trade liberalization, in the form of a reduction in bias against the foreign firm, improves both domestic and global welfare if (i) either the foreign firm's profit is sufficiently large or (ii) the initial degree of home bias is sufficiently small. If the initial home bias is large, a small reduction in the bias may reduce welfare.     

Corporate Social Responsibility Spillover and Competition Effects on the Food Industry

This paper examines the spillover and competition effects of corporate social responsibility (CSR) with duopoly competition. In employing the assumption that firm CSR increases consumer willingness to pay for the firm's products while consumer willingness to pay decreases for non‐CSR firm products, some interesting conclusions are achieved. First, CSR spillover effects increase CSR firm outputs and prices, while CSR spillover has the opposite effect on competitors. Second, CSR spillover decreases total outputs and total social welfare levels. Third, competition effects increase CSR expenditures, and CSR firms' CSR policies are the most robust when non‐CSR firms assume a leading position. It is found that total outputs and consumer utilities are highest when CSR firm acts as leader, while the relationships of social welfare among different cases are ambiguous depending on product substitution and spillover effects.     

Optimal Trade Policy with Horizontal Differentiation and Asymmetric Costs

This paper examines the optimal export policy under Bertrand competition when the products exhibit horizontal differentiation and production costs are asymmetric. The focus of this paper is on the product‐differentiation effect in the determination of the optimal export policy. We show that given that the equilibrium characteristic of a foreign firm's product R&D lies to the left‐hand side of its initial level , since the foreign firm has a unit cost advantage and the efficiency of its R&D technology is sufficiently low, a rise in the export subsidy of the domestic country increases a domestic firm's profits and then welfare by extending the degree of horizontal differentiation between the two products. Thus, the optimal export policy under Bertrand competition may turn out to be an export subsidy rather than an export tax. This result is in sharp contrast to that of Eaton and Grossman (1986 ).     

Domestic R&D,Foreign Direct Investment and Welfare

This paper provides a new rationale to examine the two‐way relationship between domestic research and development (R&D) and foreign direct investment (FDI), as well as their impacts on domestic welfare. Our analysis is based on the strategic interaction in cost‐reducing investment decisions between domestic firms and a foreign firm, which is different from the common factors that are discussed in the literature such as spillovers and technology sourcing. Our results are as follows. We show that domestic R&D investment may either increase or decrease the foreign firm's FDI incentives. Further, depending on the marginal cost of domestic firms, domestic R&D incentives can always increase regardless of the effects of domestic R&D investment on the foreign firm's FDI decision. Finally, we find that domestic welfare improves under domestic cost reduction if the slope of the marginal cost of domestic R&D investment is sufficiently small.     

Environmental Regulation: An Incentive for Foreign Direct Investment

Empirical evidence has so far failed to confirm that lenient environmental regulation attracts investment from polluting firms. In a Cournot duopoly with a foreign firm and a domestic firm, we show that the foreign firm may want to relocate to the domestic country with stricter environmental regulation, when the move raises its rival domestic firm's cost by sufficiently more than its own. The domestic (foreign) country's welfare is (usually) lower with foreign direct investment.     

Tariffs and privatization policy in a bilateral trade with corporate social responsibility

Corporate social responsibility (CSR) has become a global business strategy and thus it provides significant welfare implications for designing optimal policies. This paper investigates the impact of CSR on policy interaction between tariffs and privatization in an international bilateral trade model. We find that CSR is closely related to the government's policy decisions on tariffs. In particular, we find that the strategic tariff for increasing domestic welfare is always higher (lower) than the efficient tariff for improving global welfare when the degree of CSR is low (high). We also show that a privatization policy raises tariff and worsens (improves) domestic welfare when the degree of CSR is low (high). Finally, we demonstrate that both countries choose a nationalization policy even though the privatization policy is globally optimal when the degree of CSR is high.     

Privatization,Underpricing, and Welfare in the Presence of Foreign Competition

We analyze privatization in a differentiated oligopoly setting with a domestic public firm and foreign profit‐maximizing firms. In particular, we examine pricing below marginal cost by the public firm, the optimal degree of privatization, and the relationship between privatization and foreign ownership restrictions. When market structure is exogenous, partial privatization of the public firm improves welfare by reducing public sector losses. Surprisingly, even at the optimal level of privatization, the public firm's price lies strictly below marginal cost, resulting in losses. Our analysis also reveals a potential conflict between privatization and investment liberalization (i.e., relaxing restrictions on foreign ownership) in the short run. With endogenous market structure (i.e., free entry of foreign firms), partial privatization improves welfare through an additional channel: more foreign varieties. Furthermore, at the optimal level of privatization, the public firm's price lies strictly above marginal cost and earns positive profits.     

Corporate social responsibility,vertical product differentiation and international competition

Would a foreign firm’s consumer‐oriented corporate social responsibility (CSR) activities be rewarded by an importing country’s voluntary tariff reduction? The current paper addresses this question in an import‐competing duopoly model with vertical product differentiation. It is shown that the tariff will decrease if the foreign firm switches from a purely profit‐driven firm to a CSR firm. A consumer‐oriented CSR strategy will always hurt the domestic firm’s profit, whereas the relationship between the foreign firm’s profit and CSR sensitivity (the degree to which a firm cares about consumer welfare) is invertedly U‐shaped. When firms’ decisions to switch to CSR are endogeneized, only the foreign firm will become a CSR firm.     

Duopoly Competition with Corporate Social Responsibility

This paper highlights the effect of firms’ position on firms’ strategies with corporate social responsibility (CSR) practices under three different cases: Cournot competition; Stackelberg competition with the CSR firm taking the leader position and turnover, with the profit maximising (PM) firm playing as the leader. Some interesting conclusions are achieved. First, the CSR firm always produces more than the PM firm. Second, the outputs of both firms (the consumer surplus) under the PM firm's leading position are larger than those under Cournot. Third, the profits of both firms (producer surplus) under the PM firm playing the leading position are less than those under Cournot. Surprisingly, when the PM firm first moves, the PM firm's profits are the lowest while the CSR firm's outputs are the highest in all three cases. Finally, the relationship of social welfare under the three cases is ambiguous.     

Export Flexibility And Currency Hedging*

This article studies the behavior of an export‐flexible firm under exchange rate uncertainty. We show that the separation theorem holds if selling exclusively in the domestic market is suboptimal even under the most unfavorable spot exchange rate. Otherwise, the firm's optimal output depends on its preferences and on the underlying uncertainty. We further show that the full‐hedging theorem holds only when the firm always finds it optimal to sell its entire output in the foreign market. Otherwise, export flexibility introduces a convexity into the firm's foreign exchange risk exposure, which calls for the use of currency options for hedging purposes.     

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.     

FDI and Outsourcing in a Service Industry: Welfare Effects of Liberalising Trade and Investment

This study examines a foreign firm's entry decision and its effects on the host country's welfare in a model with a composite good in which both commodity and service generate utility for consumers. Along with the commodity it produces, a producer can provide the service by itself or outsource the service. The result shows that the incentive for foreign direct investment (FDI) in the service sector increases under liberalising trade in the final‐good market. Moreover, there exist policy combinations of trade and investment liberalisation, whereby the domestic firms' profitability is traded off with the host country's social welfare when the foreign firm provides a service through FDI or through outsourcing, respectively. Finally, the welfare after simultaneously liberalising trade and investment is not necessarily greater than that under autarky.     

On the Equivalence of Tariffs and Quotas under a Revenue Constraint

This paper sets out a duopolistic model to examine the price and welfare equivalence of tariffs and quotas, given the quota rent is equal to the tariff revenue. It shows that the domestic welfare ranking of the two trade policies crucially depends on the relative costs of the domestic and foreign firms; when the domestic firm's relative costs are lower than those of the foreign firm, a quota regime generally leads to a higher welfare level than that of an equivalent tariff regime. This finding contrasts sharply with the conclusions of Dasgupta and Stiglitz (1977 ), where it was found that a tariff regime always generates higher domestic welfare.     

Market Size and the Survival of Foreign‐owned Firms*

We develop a general equilibrium model with heterogeneous firms and foreign direct investment cost uncertainty and investigate the survival of foreign‐owned firms. The survival probabilities of foreign‐owned firms depend on firm‐level characteristics, such as productivity, and host country characteristics, such as market size. We show that a foreign‐owned firm will be less likely to be shut down when its parent firm's productivity is higher and its indigenous competitors are less productive. Although a larger market size will always reduce the survival probability of indigenous firms, it can lead to a higher survival probability for foreign‐owned firms if their parent firms are sufficiently productive.     

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.     

Welfare effects of competitive lobbying efforts in international oligopoly markets

Conventionally, rent-seeking activities have been considered to deteriorate social welfare and to distort resource allocation. This paper examines whether rent-seeking behavior can improve social welfare by focusing on the welfare effects of firms’ competitive lobbying efforts when governments can impose market entry regulation against foreign firms. We demonstrate that competitive lobbying efforts can improve social welfare when such lobbying efforts are directed to reduce market entry barriers. In addition, social welfare can be maximized when the government shows the maximum sensitivity to the foreign firm's political contributions while maintaining competitive market structure. Moreover, it is shown that the dominant strategy for a domestic firm is to allocate more resources to R&D sectors while it is optimal for foreign firms is to exert more efforts in lobbying to reduce the market entry barriers when a government makes political economic approach in market entry regulations.     

Export rivalry,vertically-related markets,and optimal public ownership policy

This paper considers the optimal public ownership policy of an upstream firm which competes with a foreign private rival. Both firms supply a produced input to the domestic and foreign downstream firms that compete in an export market. The paper shows that complete privatization of the domestic upstream firm is never optimal. It will likely be fully nationalized if its market share is high, the domestic downstream firms' market share is low, and the total number of firms in the downstream is large. Simulation results reveal that the public firm's optimal profit margin may be negative and that the government ownership level may exhibit a reswitching phenomenon as the number of domestic downstream firms keeps growing. The paper sheds light on the possibility of using government ownership policy as a pseudo-trade and industrial policy.     

Profit taxation and the mode of foreign market entry

Abstract This paper studies the role of profit taxation for an international firm's decision upon how to penetrate a foreign market – through exports or through foreign direct investment (FDI) and local supply. We show that with harmonized taxes the international firm may choose FDI even though this has welfare costs from a global point of view. With tax competition, the host country can enforce exporting instead of FDI. This leads to a Nash equilibrium associated with higher world welfare than harmonized taxes. Thus, because of the effect on entry mode, tax competition provides heretofore unexplored benefits as compared to tax harmonization.     

An analysis of entry-then-privatization model: welfare and policy implications

This study formulates a new model of mixed oligopolies in free entry markets. A state-owned public enterprise is established before the game, private enterprises enter the market, and then the government chooses the degree of privatization of the public enterprise (termed the entry-then-privatization model herein). We find that under general demand and cost functions, the timing of privatization does not affect consumer surplus or the output of each private firm, while it does affect the equilibrium degree of privatization, number of entering firms, and output of the public firm. The equilibrium degree of privatization is too high (low) for both domestic and world welfare if private firms are domestic (foreign).
