In a domestic market, a duopoly produces a homogeneous final good, pollution, pollution abatement and R&D. One of the firms (foreign) has superior technology. The government regulates the duopoly by levying a pollution tax to maximize domestic welfare. We consider the potential implementation of...

The purpose of this paper is to analyse the question, whether copyright infringement of digital products like software commonly labelled as piracy impedes innovation. We find the answer depends on the nature of piracy i.e. whether it is end-users or commercial piracy. For end user piracy,...

We consider the optimal licensing strategy of an insider patentee in a circular city of Salop’s model and in a linear city of Hotelling’s model when firms have asymmetric pre-innovation marginal costs of production and compete in prices. We completely characterize the optimal licensing...

This paper explores the effects of innovation efficiency on technology gap and product diversity between a leading firm and its competitor. Our analysis shows some interesting results: when innovation efficiency is sufficiently large and increases, the leading firm may expand technology gap, and...

This article explores the possibility of associating firm size vis-à-vis industry size with firm-level R&D led-innovation and the resultant impact(s) on industry level output and price. We consider an oligopolistic industry having one dominant firm and some fringes. Innovation by the dominant...

This paper studies the impact of cooperative R&D and advertising on innovation and welfare in a duopolistic industry. The model incorporates two symmetric firms producing differentiated products. Firms invest in R&D and advertising in the presence of R&D spillovers and advertising spillovers....

In this paper, we address the incentives to invest in environmental innovation of enterprises that exercise market power in the output market and also buy and sell pollution permits. Differently from the existing literature, using a market approach we explicitly model the interaction between the...

We characterize the effect of overlapping ownership (OO) on investments in product innovation. We analyze two opposing forces: (1) OO induces firms to internalize that success on their own behalf erodes the rivals’ business, reducing investments; (2) OO softens competition in the product...

Two suppliers of a homogenous good know that, in the second period, they will be able to collude. Gains from collusion are split according to the Nash bargaining solution. In the first period, either of them is able to invest into process innovation. Innovation changes the status quo pay-off,...

A duopoly model of cost reducing R&D-Cournot competition is extended to study the endogenous timing of R&D strategic investment. Under the assumption that R&D spillovers only flow from the R&D leader to the follower, sequential and simultaneous play at the R&D stage are compared, in order to...
