The issue of the persistence of monopoly when at least one labour-managed firm takes part in an auction for a cost-reducing innovation is tackled in this paper. It is shown that (i) when the incumbent is a profit-maximizing firm while the entrant is a labour-managed firm, monopoly persists; (ii)...

We revisit the Cournot–Bertrand debate in the light of Cournot, Edgeworth and Launhardt, tracing back to Launhardt the origin of price competition in duopoly models with constant returns to scale. Then, we discuss the formalisation of consumer utility function for differentiated products,...

Different market settings are considered in a free trade environment, where firms can choose technology, quality, and price or quantity. The shape of competition in prices requires the intervention of governments, via a common antidumping policy to make firms converge on the simultaneous...

This paper examines the impact of voluntary export restraints (VERs) in an international duopoly modelled as a differential game. With a Ramsey capital accumulation dynamics, the game admits multiple steady states, and a VER cannot be 'voluntarily' employed by the foreign firm in case of Cournot...

A methodological discussion is proposed, aiming at illustrating an analogy between game theory in particular (and mathematical economics in general) and quantum mechanics. This analogy relies on the equivalence of the two fundamental operators employed in the two fields, namely, the expected...

We take a game theory approach to study the make-or-buy decisions of firms in a mixed duopoly. We assume that a managerial firm and a profit-oriented firm compete in a duopoly market for a final good, and they can choose whether making an intermediate input or buying it from a monopolistic...

In this paper we analyse a setup where consumers are heterogeneous in the perception of environmental quality. The equilibrium is verified in a setting with horizontal and vertical (green) differentiation. Profits are increasing in the mis- perception of quality, while the investment in green...

In recent years Open Innovation (OI) processes have been receiving growing attention from the empirical and theoretical economic literature, where a debate is taking place on the aspects of complementarity or substitutability between internal R&D and OI spillover. By means of a differential game...
