Abstract We introduce an explicit environmental incentive into a managerial compensation contract in the context of a Cournot duopoly with pollution externalities under an emissions tax regime. We show that, depending on the effectiveness of “green” R&D, compared to a standard sales compensation contract, the explicit environmental focused contract results in more abatement. As a consequence, the regulator sets a lower emissions tax, and social welfare is higher. Moreover, in general, firm owners earn higher profits when adopting the environmental delegation contract.

AbstractBy analysing interlocking cross-ownership, this work reconsiders the inefficiency of activist governments that set subsidies for their exporters (Brander and Spencer, J Int Econ 18:83–100). Making use of a third-market Cournot duopoly model, we show that the implementation of strategic trade policy in the form of a tax (subsidy) when goods are differentiated (complements) is Pareto-superior to free trade within precise ranges of firms’ cross-ownership, richly depending on the degree of product competition. These results challenge the conventional ones in which public intervention (1) is always the provision of a subsidy and (2) always leads to a Pareto-inferior (resp. Pareto-superior) equilibrium when products are substitutes (resp. complements).

Although oligopoly theory is generally concerned with the single-product firm, what is true in the real word is that most of the firms offer multiproducts rather than single products in order to obtain cost-saving advantages, cater for the diversity of consumer tastes, and provide a barrier to entry. We develop a dynamical multiproduct Cournot duopoly model in discrete time, where each firm has an owner who delegates the output decision to a manager. The principle of decision-making is bounded rational. And each firm has a nonlinear total cost function due to the multiproduct framework. The Cournot Nash equilibrium and the local stability are investigated. The tangential bifurcation and intermittent chaos are reported by numerical simulations. The results show that high output adjustment speed can lead to output fluctuations which are characterized by phases of low volatility with small output changes and phases of high volatility with large output changes. The intermittent route to chaos of Flip bifurcation and another intermittent route of Flip bifurcation which contains Hopf bifurcation can exist in the system. The study can improve our understanding of intermittent chaos frequently observed in oligopoly economy.

We examine the effects of and the incentives for increasing input efficiency within a spatially segregated  Cournot duopoly with monopoly trade unions whose utility functions depend on both wages and employment. We show that with neoclassical as well as Leontief technology, unions raise wages to appropriate fully the gains from labor-saving technological (or organisational) improvements, leaving the firm with no incentive to invest in increasing the efficiency of workers. However, capital-saving     technological improvement may be profitable depending on the elasticity of substitution. Finally, we examine the implication of a fixed minimum wage (or competitive labor market) in one country.
