We characterize the interplay between firms’ decision in terms of product differentiation and the nature of their ensuing market behaviour. We prove the existence of a non-monotone relationship between firms’ decision at the development stage and their intertemporal preferences.

The authors characterize the interplay between firms' decisions in terms of either horizontal or vertical product differentiation and their ensuing price behavior, be that collusive or not. They prove the existence of a non-monotone relationship between firms' decisions at the development stage...

We characterise the interplay between firms' decision in product development undertaken through a research joing venture (RJV), and the nature of their ensuing market behaviour. Participant firms in an RJV face a trade-off between saving the costs of product innovation by developing similar...

We characterise the interplay between firms' decisions in product development, be it joint or independent, and their ensuing repeated price behaviour, either collusive or Bertrand- Nash. Firms face a choice between participating in a joint venture inventing a single product, and in independent...

We characterize the interplay between firms' decision in terms of product standardization and the nature of their ensuing market behaviour. We prove the existence of a non-monotone relationship between firms' decision at the product stage and their intertemporal preferences.

We analyse optimal penal codes in both Bertrand and Cournot supergames with product differentiation. We prove that the relationship between optimal punishments and the security level (individually rational discounted profit stream) depends critically on the degree of supermodularity in the stage...

We inspect the interlink between the endogenous choice of price- and quantity- setting behavior in an oligopolic market, and cost sharing among oligopolists. A typical situation of this sort is an oligopoly game where firms invest in product development first, and ten play a marketing game...
