We first study the optimality of a committed policy mix of tax and subsidy to control pollution when firms are involved in abatement technology R&D that is subject to knowledge spillovers. Then a comparison of tax and subsidy is provided when the policy mix is not available and the regulator can...

We examine the relationship between competition and innovation in an industry where production is polluting and R&D aims to reduce emissions ("green" innovation). We present an n-firm oligopoly where firms compete in quantities and decide their investment in "green" R&D. When environmental...

This paper provides a review of the literature on competitiveness and leakage concerns associated with differentiated climate abatement commitments among countries. The literature reviewed is not exhausted, but it is sufficient to provide a balanced view of both academics and policy circles....

The idea that properly designed environmental regulations can improve a firm's competitiveness while simultaneously contributing to a cleaner environment through the development of so-called 'win-win' innovations (i.e., that reduce environmental damage while simultaneously increasing profits) is...

There is an increasing concern about the imbalance between urbanisation and environmental conservation, with over half of the world's population living in urban environments. Therefore, urban greening aims to incorporate nature into the city, recovering native flora in a sustainable way. Urban...

This paper evaluates the effects of the lack of regulatory commitment on emission tax applied by the regulator, abatement effort made by the monopoly and social welfare comparing two alternative policy games. The first game assumes that the regulator commits to an ex-ante level of the emission...

This paper performs a comparison of two well known approaches for modelling R&D spillovers associated with investment in green technology, namely D'Aspremont-Jacquemin and Kamien-Muller-Zang. We show that there is little qualitative difference between the models in terms of total surplus...
