This paper analyzes the relationship between market shares and welfare under the assumption of Cournot-oligopolistic interdependence in production. The model is general enough to deal with multiple countries, oligopolists with different levels of marginal costs within each country, and any distribution of world demand across countries. It is found that the elimination of a minor firm harms the country if the country's total production is very little. However, such a policy always benefits the country if it exports the commodity. The welfare effect of production subsidies and the case of foreign ownership of firms are also discussed. 相似文献

This paper shows that under imperfect competition, the welfare effects of indirect tax harmonization may depend crucially on whether taxes are levied by the destination or the origin principle. In a standard model of imperfect competition, while harmonization always makes at least one country better off, and may be Pareto-improving, when taxes are levied under the destination principle (which currently applies in the European Union), harmonization of origin-based taxes (as recently proposed by the European Commission) is certain to be Pareto-worsening when the preferences in the two countries are identical, and is likely to be so even when they differ. 相似文献

We show that the core is non-empty and coincides with the set of competitive equilibria for an assembled product industry.

Cross-Border Pollution,Terms of Trade,and Welfare 总被引:2,自引:1,他引:1

We construct a two-good general equilibrium model of international trade for two small open economies where pollution from
production is transmitted across borders. Governments in both countries impose emission taxes non-cooperatively. Within this
framework, we examine the effect of changes in the degree of cross-border pollution on Nash emission taxes, emission levels
and welfare. We do so under two scenarios: when changes in cross-border pollution do not affect domestic pollution (non-strategic)
and when they do (strategic). We also examine the effect of changes in international terms of trade on pollution and welfare
when cross-border pollution is non-strategic.

This paper develops a theoretical model of product innovation where research and development (R&D) effort by a monopolist firm is endogenous and its outcome uncertain. The government attempts to aid such efforts with a matching grant. We consider different scenarios depending on whether two parties act simultaneously, act sequentially, or take part in a dynamic cooperative game with a trigger strategy. We also consider cases (i) when the products are exported, (ii) when the firm lobbies for R&D subsidy, and (iii) when the firm is foreign owned. We characterize situations when government intervention increases the chances of product innovation and when it does not. 相似文献

We develop a two‐country Cournot oligopoly model with product differentiation across countries and production‐generated pollution. The abatement of pollution by the firms in response to emission taxes is endogenous, and the number of firms can be fixed or there may be free entry and exit of firms in both countries. We propose particular unilateral and multilateral piecemeal policy reforms of emission taxes and production subsidies such that domestic industries will not suffer any loss of international competitiveness (defined in terms of either market share or profits), emission levels will be lower, and welfare could be higher in both countries. 相似文献

This paper examines whether linking environmental cooperation with international trade agreements improves the welfare of the participating countries and allows countries to move closer to free trade compared with trade‐only agreements. The model is an infinitely repeated game with the threat of reversion to Nash equilibrium if an economy deviates from the cooperative agreement. It is found that such a synergy exists in a symmetric two‐country model with two goods, both emitting pollutants even when the externalities have local impact. A combination of analytic and numerical simulation analysis is used to derive the conclusions. 相似文献

This paper attempts to measure pure tax efficiency of fifteen major Indian states (Andhra Pradesh, Assam, Bihar, Haryana,
Gujarat, Karnataka, Kerala, Madhya Pradesh, Maharashtra, Orissa, Punjab, Rajasthan, Tamilnadu, Uttar Pradesh and West Bengal)
for the period 1980–81 to 1992–93 in a manner that allows this efficiency to vary both across time as well as across states.
It is discovered that there is a moral hazard problem in the design of central grants in that higher grants by the central
government to the state governments reduce efficiency of tax collection by these states. The less poor states are more efficient
in tax collection. The rankings of states by tax efficiency for the various years do not converge. An index of aggregate tax
efficiency is calculated and it appears that this index has been stagnating. It is argued that the weight placed on tax effort
in the formula determining central grants to state governments should be increased to improve tax efficiency of state governments.

This paper examines the implications of ex ante skill heterogeneity for long run inflation. We develop a dynamic general equilibrium model in which there are two types of labor (skilled and unskilled), two types of capital (human and physical), and money is introduced via a cash in advance constraint on consumption purchases. Skill heterogeneity is characterized in terms of (i) a parameter governing the ease with which the two types of labor can be substituted for each other in production; and (ii) the “productivity” of human capital in the production of skill. The model includes the accumulation of human capital which in turn creates skill heterogeneity among workers through an efficiency wage mechanism. Numerical experiments indicate that there is a range of parameter estimates in which the Friedman Rule may not be optimal. Furthermore, our quantitative experiments also indicate that there is a range of parameter values in which a greater degree of skill heterogeneity may be associated with a greater preference for inflation. Empirically, we also find that the inflation and heterogeneity correlation is positive. 相似文献
