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.     

TARIFF POLICY AND WELFARE IN AN INTERNATIONAL DUOPOLY WITH CONSUMER‐FRIENDLY INITIATIVE

The purpose of this paper is to explore how strategic tariff policy and welfare are affected by the consumer‐friendly initiative of foreign exporting firms. We define a firm that is consumer‐friendly or non‐profit‐based if it considers both its own profit and consumer surplus. This paper extends Brander and Spencer by taking the consideration of consumer‐friendly firms into an international duopoly, and within such context examining the tariff policy and welfare. The consumer‐friendly initiative that leads to trade liberalization is a ‘Win‐Win‐Win’ solution in the sense that it is not only beneficial for foreign exporting firms, but also for the government and consumers of the importing country.     

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.     

Mixed oligopoly, optimal privatization, and foreign penetration

This paper examines the impact of foreign penetration on privatization in a mixed oligopolistic market. In contrast to the simple framework of single domestic market with foreign entry by entry mode of foreign direct investment (FDI) or exports, our result shows that government should increase the degree of privatization along with increasing proportion of domestic ownership of multinational firms. Furthermore, we show that an increase in domestic ownership of multinational firms raises all domestic private firms' profit and social welfare, while it may either increase or decrease public firm's profit. With the aid of numerical example, intensive competition from private firms in general will enhance the degree of privatization gradually; in particular, the degree of privatization is lower in the presence of multinational firms.     

Partial Privatization,Foreign Competition,and Optimum Tariff*

Using a simple international mixed oligopoly model with one public and one or more foreign firms, this paper examines the effect of partial privatization or foreign competition on optimum tariffs and finds that foreign competition lowers the optimal tariff rate but partial privatization raises it. This result implies that trade liberalization is welfare improving if a country opens up its economy by allowing foreign competition. However, the liberalization policy is not desirable when the country only partially or completely privatizes its publicly‐owned enterprises.     

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.     

Foreign competition and optimal privatization with excess burden of taxation

We examine in a mixed oligopoly setting how foreign competition and the excess burden of taxation will affect privatization policy in the presence of strategic tax/subsidy policies. We show that in the presence of excess burden of taxation with foreign competitors, output subsidy coupled with import tariff and partial privatization is adopted to improve the social welfare. However, if the excess burden of taxation is relatively large, the government may switch to use production tax coupled with tariff policy and partial privatization to improve the social welfare.     

Vertically Related Markets,Foreign Competition and Optimal Privatization Policy

This paper examines the optimal privatization policy in vertically related markets in which an upstream public firm competes with a foreign private rival in supplying a produced input to the domestic and foreign downstream firms competing in the domestic market. It shows that if the upstream public firm's market share is sufficiently high, full nationalization is optimal and the resulting profit margin is positive. However, complete privatization is never optimal. Numerical simulations reveal both the diverse optimal privatization regimes and the patterns of optimal privatization levels with varying numbers of the domestic and foreign downstream firms.     

Lack of commitment to future privatization policies may lead to worst welfare outcome

We investigate the welfare consequences of a lack of commitment to future privatization policies. The government implements a privatization policy after the competition structure is determined by the entry of private firms. We find that in an equilibrium, the government fully privatizes (nationalizes) a public firm if private firms expect that the government fully privatizes (nationalizes) the public firm. This is because an increase in the number of firms entering a market increases the government's incentive to privatize the public firm, which mitigates future competition and stimulates entries. The full-privatization equilibrium is the worst privatization policy among all possible (either equilibrium or non-equilibrium) privatization policies for welfare because it causes excessive market entry of private firms. Partial commitment of a minimal public ownership share may mitigate this problem.     

Brotherhood of competition: Foreign Direct Investment and domestic mergers

We examine the effects of mergers on Foreign Direct Investment (FDI), and on shaping national policies regarding FDI. In this work we develop a partial equilibrium model of an oligopolistic industry in which a number of domestic and foreign firms compete in the market for a homogeneous good in a host country. It is assumed that the number of foreign firms is endogenous and can be affected by the government policy in the host country. The government sets the policy (subsidies) to maximise social welfare. We allow domestic mergers. Our main results suggest that when the host country government imposes discriminatory lump-sum subsidy in favor of foreign firms, a merger of domestic firms will increase the number of FDI if the subsidy level is exogenous. With an endogenous level of subsidy, a merger of domestic firms will decrease (increase) the welfare if the domestic firms are more (less) efficient.     

Two-Part Trade Policy under Imperfect Competition

In this paper we consider the potential gain of a government pursuing a two-part trade policy: an import license for entry, along with a per-unit tariff on imports. The model is a two-stage game of complete but imperfect information. In the first stage, the domestic government sets trade policy, while in the second stage the home and foreign producers behave as Cournot competitors. The paper demonstrates that the optimal trade policy depends upon the number of firms, the degree of heterogeneity in cost functions, and the degree of convexity in cost functions.     

Presence of foreign investors in privatized firms and privatization policy

This paper investigates how the presence of foreign investors in privatized firms affects privatization policy in a mixed oligopoly. We find that an increase in the stockholding ratio of foreign investors in a privatized firm increases the optimal degree of privatization, whereas an increase in the penetration of foreign firms in product markets reduces it. These results imply that the degree of openness of financial markets and that of product markets have contrasting implications for the optimal privatization policy.     

The Optimal Privatization Policies under an International Mixed Duopoly

This paper explores the socially optimal privatization policies under the setting of international mixed duopoly. We find that partial privatization is socially optimal under Cournot competition and private leadership competition, whereas full nationalization is socially optimal under public leadership competition. Moreover, the equilibrium social welfare under private leadership competition is higher than that observed under Cournot competition and that observed under private leadership competition, which differs from the findings of Matsumura ( 2003b ). We also show that the endogenous timing game has a subgame perfect Nash equilibrium outcome, under which the government chooses a partial privatization policy, and private leadership competition emerges as the optimal output decision sequence of firms. An important policy implication from this paper is that the government should partially privatize the public firm and facilitate the emergence of private leadership competition in an international mixed market.     

MARKET‐DEMAND BOOSTING AND PRIVATIZATION IN A MIXED DUOPOLY

This study incorporates demand‐boosting strategies into a mixed duopoly model in order to consider the endogenous determination of market demand. The results indicate equilibrium characteristics that differ from those found under an exogenous demand setting. As consumers become more sensitive to the demand‐boosting strategies of firms, the government must choose a lower level of privatization. This suggests that the responsiveness of consumer demand to the demand‐boosting strategies of firms constitutes a limiting factor for privatization.     

Priorities and sequencing in privatization: Evidence from Czech firm panel data

While privatization of state-owned enterprises has been one of the most important aspects of the economic transition from a centrally planned to a market system, no transition economy has privatized all its firms simultaneously. This raises the question of whether governments privatize firms strategically. In this paper we examine the determinants of the sequencing of privatization. To obtain testable predictions about the factors that may affect sequencing, we investigate the following competing government objectives: (i) Maximizing efficiency through resource allocation; (ii) maximizing public goodwill from the free transfers of shares to the public; (iii) minimizing political costs; (iv) maximizing efficiency through information gains; and (v) maximizing privatization revenues. Next, we use firm-level data from the Czech Republic to test the competing predictions about the sequencing of privatization. Consistent with the hypotheses of a government priority on revenues and public goodwill, we find strong evidence that more profitable firms were privatized first. The sequencing of privatization is also consistent with maximizing efficiency through information gains. Our results indicate that many empirical studies of the effects of privatization on firm performance suffer from a selection bias.     

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.     

Optimal privatization policy with asymmetry among private firms

We revisit the relationship between the optimal privatization policy and market competition indexes such as the Hirschman–Herfindahl index. It is affected by the number of the firms and asymmetry among the sizes of the firms; the smaller the number of firms and the more asymmetry among firms, the higher the market concentration index. The literature on mixed oligopolies suggested that the optimal degree of privatization increases with the number of private firms, and thus, decreases with the market competition index, assuming that all private firms are homogeneous. We investigate how asymmetry among private firms affects the optimal degree of privatization. We propose the simplest and natural model formulation to discuss asymmetry among private firms. We find that the optimal degree of privatization is either nonmonotone or monotonically increasing, and thus never monotonically decreasing, in asymmetry among private firms.     

Profit tax and tariff under international oligopoly

A simple model of international duopoly is developed to examine the effects of tariff and corporate profit tax. It is shown that in an export-cum-on-site-production regime, a tariff continues to be an effective instrument for shifting net profit away from foreign to domestic firms. A corporate profit tax, on the other hand, could lower the domestic output and employment and decrease the net earnings of both domestic and foreign firms. Thus when the host government's ability to raise tariff is limited, it should seriously consider a corporate tax cut policy to achieve the dual purpose of creating more jobs and increasing corporate earning at home.     

Tariff Rate as a Public Good

If domestic firms lobby for protection, the tariff rate is a public good to all domestic firms, whether they engage in lobbying or not. This paper analyzes how the endogenous tariff rate as a public good depends on the group size in two‐stage lobbying models. The result depends not only on whether domestic firms lobby cooperatively or not, but also on whether domestic firms incur indirect lobbying costs or not. This paper shows that if free riding is not very serious and if the number of domestic firms is small compared to the number of foreign firms, entry of a domestic firm is likely to increase the equilibrium tariff rate.     

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.
