PROFIT TAX AND FIRM MOBILITY IN A THREE‐COUNTRY MODEL

We construct a three‐country model that incorporates international relocation by imperfectly competitive firms and examine both the effects of each country's profit tax reduction on the consumption and welfare of all countries, and the incentive for the countries to decrease the profit tax. In such a model, both the terms of trade and international relocation of firms offer the key to understanding the impacts of one country's profit tax policy. In particular, we note that the relocation of firms from the other two countries is positively related to the wage incomes of the third country through a shift in labour demand, and the terms‐of‐trade improvement is not only positively related to the wage incomes, but also negatively related to profit incomes through a shift in world consumption demand. We show that (i) in a three‐country world economy, regardless of the reduction's source, the profit tax reduction of each country leads to relocation of firms away from foreign countries toward its own economy and deteriorates the terms of trade of its economy and (ii) this becomes a ‘beggar‐thy‐neighbour’ policy in the sense that it lowers the welfare of the other foreign countries.     

On selective indirect tax reform in developing countries

The current consensus on indirect tax reform in developing countries favors a reduction in trade taxes with an increase in VAT to raise revenue. The theoretical results on selective reform that underlie this consensus are, however, derived from partial models that ignore the existence of an informal economy. Once the incomplete coverage of VAT due to an informal economy is acknowledged, we show that, contrary to the current consensus, the standard revenue-neutral selective reform of trade taxes and VAT reduces welfare under plausible conditions. Moreover, a VAT base broadening with a revenue-neutral reduction in trade taxes may also reduce welfare. The results raise serious doubts about the wisdom of the indirect tax reform policies pursued by a large number of developing countries.     

Regional versus Multilateral Trade Liberalization,Environmental Taxation,and Welfare

The paper considers trade between identical countries with imperfectly competitive markets, and compares the impacts of regional and multilateral tariff reduction on strategic environmental taxation and welfare. While both forms of trade liberalization increase production and consumption in tariff‐reducing countries, regionalism also reduces production in a non‐participating country and may decrease its consumption. Consequently, regionalism and multilateralism change pollution tax and welfare in the tariff‐reducing countries in similar ways when pollution is local, but in dissimilar ways for global pollution. When pollution is global, regionalism is likely to be preferred to multilateralism for the establishment of free trade among countries.     

The effects of regional tax and subsidy coordination on foreign direct investment

This paper analyses the effects of a regionally coordinated profit tax or location subsidy in a model with three active countries, one of which is not part of the union, and a globally mobile firm. We show that regional coordination can lead to two types of welfare gain. First, for investments that would take place in the union in the absence of coordination, a coordinated tax increase can transfer location rents from the firm to the union. Second, by internalising all of the union's benefits from foreign direct investment, a coordinated tax reduction can attract more welfare-enhancing investment than when member states act in isolation. Depending on which motive dominates, tax levels may thus rise or fall under regional coordination.     

Trade and financial liberalization with asymmetric information in bank financing

We investigate trade and financial openness in a small developing country where entrepreneurs need bank financing to operate in an import‐competing sector but banks do not observe their ability. This informational asymmetry causes adverse selection of low‐ability individuals into entrepreneurship and also prevents poor but able individuals from being entrepreneurs. We find that trade opening improves national welfare, but a tax is needed on foreign financial capital. Trade opening reduces an income gap between the rich and the poor, while financial opening affects this income gap ambiguously.     

Tax Policies,Regional Trade Agreements and Foreign Direct Investment: A Welfare Analysis

In this paper, we develop a partial equilibrium three‐country model to examine the relationship between regional trade agreements (RTAs) and foreign direct investment (FDI) in an environment with double taxation. Our analysis shows that FDI is welfare‐improving for at least one or both of the two regional countries if wage asymmetry is significantly large. FDI and an RTA are also welfare‐improving for the high‐wage country and the region if the wage differential is not small. We also examine the role of repatriation taxes in affecting the determination of firm location under an RTA. Our results suggest that the signing of an RTA may induce relocation from the high‐wage country to the low‐wage country unless an increase in the repatriation tax rate also occurs.     

Strategic Environmental Policies when Waste Products are Tradable

The paper deals with international trade in hazardous waste products when there is an international oligopoly market for waste, and both waste‐importing and waste‐exporting countries act strategically to utilize national environmental policies to attach rents arising from trade in waste. The authors model a multiple‐stage game where waste is generated in an industrialized country as a byproduct of production, and potentially is exported to some less‐developed countries, if not abated locally, or imposed on local residents at a cost of an environmental tax. In the market for waste, an oligopolistic supply is assumed. The demand for waste is perfectly competitive, with waste‐processing firms guided by marginal disposal costs and environmental taxes levied by foreign countries. With each country playing Nash, the analysis finds domestic and foreign taxes to be distorted from the Pigouvian taxes in such a way that the domestic (waste‐exporter) tax rate is set below, and the foreign tax rate is set above, the Pigouvian taxes. However, a global welfare optimum requires tax distortions in the opposite direction, in the sense that foreign environmental taxes must be set below the Pigouvian tax rate.     

Tax Policy When Countries Compete for Third Market Exports

We examine the welfare and other consequences of tax policy in a third market export model where duopolists located in two countries compete in prices. With tax competition between governments, we allow for welfare‐maximizing governments in the two countries to delegate tax setting responsibility to policy‐makers who have different objectives than the governments. The unique equilibrium in the tax competition environment involves both governments delegating tax setting responsibility to tax revenue‐maximizing policy‐makers. This equilibrium yields higher welfare for both countries than the outcome when the governments delegate to welfare‐maximizing policy‐makers. The paper also compares tax competition with tax harmonization and shows that when the entire export market is served, tax harmonization improves the welfare of the country that houses the low cost firm, while the other country may be immiserized.     

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.     

Migration,Foreign Aid and the Welfare State

Aspects related to the links between international migration, foreign aid and the welfare state are highlighted in this paper. Migration is modeled as a costly movement from an aid‐recipient developing country with low income and no welfare state, towards a rich donor, developed country with a well‐developed welfare state. Within this model, it is found, among other things, that the best response of the developed donor country is to increase aid as the co‐financing rate by the recipient country increases. When the immigration cost decreases, e.g. as a result of greater economic integration between the two countries, it is beneficial for the donor country to increase aid and the recipient country to increase the co‐financing rate.     

International Commodity Taxation under Monopolistic Competition

We analyze non‐cooperative commodity taxation in a two‐country trade model characterized by monopolistic competition and international firm and capital mobility. In this setting, taxes in one country affect foreign welfare through the relocation of mobile firms and through changes in the rents accruing to capital owners. With consumption‐based taxation, these fiscal externalities exactly offset each other and the non‐cooperative tax equilibrium is Pareto efficient. With production‐based taxation, however, there are additional externalities on the foreign tax base and the foreign price level that lead non‐cooperative tax rates to exceed their Pareto efficient levels.     

Trade policies, concentration, growth and welfare

The aim of this paper is to analyse, through a theoretical model, the effects that the trade integration of two countries may have on industrial location, growth and welfare.The conclusions reached finally depend both on whether the import or the export costs are affected by the trade policies on which the integration process is based and on whether the rich or the poor country introduces them. In general, when integration leads to an increase of industrial concentration in the rich country, the growth rate increases and welfare improves in both countries. If integration means that industry moves to the poor country, the growth rate decreases; in spite of this, in this case the poor country can also improve its welfare.     

The effects of labour unions on international capital tax competition

Abstract We analyze the impact of labour market rigidities on tax competition between two imperfectly integrated countries. Following a shift from a competitive to a unionized labour market in both countries, the capital tax can be adjusted upward in the country with the less rigid labour market, whereas the capital tax is always adjusted downward in the other country. Moreover, by reducing the labour cost differential between countries, trade liberalization gives rise to tax and welfare convergences. Finally, when a country adopts a flexible labour market, the unionized country may attract the majority of capital.     

The limitations of decentralized world redistribution: An optimal taxation approach

A centralized scheme of world redistribution that maximizes a border-neutral social welfare function, subject to the disincentive effects it would create, generates a drastic reduction in world consumption inequality, dropping the Gini coefficient from 0.69 to 0.25. In contrast, an optimal decentralized (i.e., with no cross-country transfers) redistribution has a miniscule effect on world income inequality. Thus, the traditional public finance concern about the excess burden of redistribution cannot explain why there is so little world redistribution.Actual foreign aid is vastly lower than the transfers under the simulated world income tax, suggesting that voluntary world transfers - subject to a free-rider problem - produces an outcome that is consistent with rich countries such as the United States either placing a much lower value on the welfare of foreigners, or else expecting that a very significant fraction of cross-border transfers is wasted. The product of the welfare weight and one minus the share of transfers that are wasted constitutes the implicit weight that the United States assigns to foreigners. We calculate that value to be as low as 1/2000 of the value put on the welfare of an American, suggesting that U.S. policy is consistent with social preferences that place essentially no value on the welfare of the citizens of the poorest countries, or that implicitly assumes that essentially all transfers are wasted.     

Trade agreements, bargaining and economic growth

Rebelo’s two-sector endogenous growth model is embedded within a two-country international trade framework. The two countries bargain over a trade agreement that specifies: (i) the size of the foreign aid that the richer country gives to the poorer one; (ii) the terms of the international trade that takes place after the aid is given. Foreign aid is given not because of generosity, but because it improves the capital allocation across the world and thus raises total world production. This world production surplus enables the rich country to raise its equilibrium consumption and welfare beyond their no-aid levels. To ensure it, the rich country uses a trade agreement to condition the aid on favorable terms of trade.     

Environmental capital flight and pollution tax

This paper analyzes the impacts of a production pollution tax on environmental capital flight and national product in a two-country static general equilibrium model with two-way foreign investment. It is assumed that the capital input in both countries is a composite good of domestic and imported capital. And pollution is assumed to originate in the production process. The productivity of capital in each country is negatively (or positively) related to the worldwide aggregate emissions.The analysis shows that when a domestic pollution tax is levied, domestic capital outflows increase and foreign capital inflows decrease for sufficiently high elasticities of substitution between labor (immobile input) and capital (mobile input) in both countries. Moreover, with negative transnational externalities, increases of a domestic pollution tax reduce domestic production and increase foreign production. The difficulty of substitution between immobile and mobile inputs hinders the optimal allocation of worldwide capital and national product. In this paper, the optimal pollution tax is based on global welfare maximization, not on global income maximization, taking into consideration the impact of income change on individual welfare. Therefore, an optimal pollution tax in the developing country should be lower for a given rate of pollution.     

Tax Principles and Tariff‐Tax Reforms under International Oligopoly

In a two‐country duopoly model, this paper compares destination‐ and origin‐based commodity taxes adjusted to tariff reductions so that the world price and foreign welfare remain unaltered. We first find that this tariff‐tax reform reduces domestic welfare under the destination principle while the opposite holds under the origin principle. Then, it is shown that this ranking is reversed if exports are taxed. In short, which is preferable between destination and origin taxes depends on the tax principle and which between imports and exports are taxed.     

Does Preferential Trade Benefit Poor Countries? A General Equilibrium Assessment with Nonhomothetic Preferences

We develop a Ricardian model of trade with nonhomothetic preferences to analyze preferential trade agreements (PTAs) among countries of different stages of economic development. The richer a country is, the more likely will PTAs improve its terms of trade, also when it is a non‐member. Rich non‐member countries are also less likely to incur welfare losses from PTAs. PTA membership only guarantees welfare gains for countries that are too poor to import the goods rich countries produce. For all other countries, the welfare effects of joining PTAs depend on the world income distribution and on the strength of comparative advantages.     

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.     

Tax Enforcement Policy and the Provision of Public Goods with the Presence of Tax Havens

A tax competition model is presented to investigate the effects of tax havens on the public good provision. We show that when countries facing a rise in tax havens change their tax enforcement strategies in response, the existence of tax havens may result in a higher level of equilibrium public good provision as compared to the case with no tax havens. Accordingly, tax havens could be welfare enhancing for non‐haven countries. This result offers a possible explanation for the recent empirical evidence that the corporate tax revenues in high‐tax countries have actually increased with the growth in the flow of foreign direct investment to tax havens.
