We investigate a dynamic Cournot duopoly with intraindustry trade, where firms invest in R&D to reduce the level of iceberg transportation costs. We adopt both open-loop and closed-loop equilibrium concepts, showing that a unique (saddle point) steady state exists in both cases. In the open-loop...

We adopt a dynamic approach to model the behaviour of a multiproduct monopolist investing in process innovation, and either product differentiation, or product proliferation, or both. Irrespective of the number of activities appearing in the R&D portfolio, we prove that, depending on initial...

This paper investigates the strategic effect of the bundling strategy that is adopted by a multi-product firm that produces two complementary goods and faces one single-product rival in each market. I consider both the Cournot and Bertrand cases. When firms compete in quantities, bundling is...

We revisit a recent literature on productive asset exploitation describing a differential oligopoly game of resource extraction under static, linear feedback and nonlinear feedback strategies, where we explicitly allow for the possibility of resource exhaustion. We show that (i) feedback rules...

We consider a start-up firm run by an owner-manager who applies for a bank loan to implement a project based on two complementary activities. Complementarity can be improved by coordinating the activities, either by the manager or by an internal employee to whom the task is delegated. In the...

We consider a two-stage Cournot duopoly game with horizontally differentiated products where firms decide whether to improve transport technology or to activate product innovation. Transport technology increases the quantity sold in the market, while product innovation reduces product...

In this article we study complementarity between market-enhancing product innovation and cost-reducing process innovation in a monopoly setting. First, we consider the possibility for a firm to alternatively invest only along one of the two directions and compare the incentives of process vs....

We revisit Maxwell's (1998) analysis to show that his results are incompatible with the assumption of full market coverage. As a consequence, the effects of MQS regulation on the high-quality firm's incentive to adopt a more efficient technology cannot be assessed in this model.
