We employ a common agency model to examine how green lobbies affect the determination of trade and environmental policy in two large countries that are linked through trade flows and transboundary pollution. We show that, when governments are not restricted in their ability to use trade...

We describe a model of international, multidimensional policy coordination where countries can enter into selective and separate agreements with different partners along different policy dimensions. The model is used to examine the implications of negotiation tie-in - the requirement that...

In this paper we build an endogenous growth model where human capital and ideas are complements in the long-run equilibrium and technological progress takes the form of a continuous increase in the number of horizontally differentiated varieties of intermediate inputs. One peculiarity of the...

Using a vertical differentiation model of endogenous growth with stochastic R&D activity, we characterise the optimal patent lifetime a government would set in order to maximise economic growth. We show that a finite patent lifetime does exist and is unique provided that the expected rate of...

Tools for recreational resources management are topics of great theoretical and practical interest. The most commonly used tool undoubtedly is the licence or permit. The implementation of a system of licences to regulate the use of a natural resource is far from simple as it presupposes the...

We incorporate a renewable resource into an overlapping generations model without capital and with quasi-linear preferences. Besides being an input for production the resource serves as a store of value. We characterise the dynamics, efficiency and stability of the steady state equilibria. The...

The most cost-effective policies for achieving CO2 abatement (e.g., carbon taxes) fail to get off the ground politically because of unacceptable distributional consequences. This paper explores CO2 abatement policies designed to address distributional concerns. Using an intertemporal numerical...

The Clean Development Mechanism (CDM) offers abatement cost savings under the Kyoto Protocol by allowing credits for emission reductions obtained in signatory developing countries. The paper shows that it is necessary to include technology transfers in the CDM to obtain correct incentives for...

In this paper we consider Voluntary Agreements (VAs) as an information-sharing device. In a duopoly model firms compete à la Cournot and aim to reduce environmental damages because consumers have green preferences that partially internalise negative externalities. However both firms are...
