This paper addresses two basic issues related to technological innovation and climate stabilisation objectives: i) Can innovation policies be effective in stabilising greenhouse gas concentrations? ii) To what extent can innovation policies complement carbon pricing (taxes or permit trading) and...

This paper analyses a set of new scenarios for energy markets in Europe to evaluate the consistency of economic incentives and climate objectives. It focuses in particular on the role of natural gas across a range of climate policy scenarios (including the Copenhagen Pledges and the EU Roadmap)...

This paper sheds light on the role of the impact of taxes on energy production versus tariffs on imported goods for trade, energy demand, and welfare. For this, we develop a structural Eaton-Kortum type general equilibrium model of international trade which includes an energy sector. We estimate...

If some, but not all, countries are cooperating to reduce CO2 emissions, it can be argued that: A high carbon tax on carbon-intensive tradable sectors in the cooperating countries will reduce the production of goods from these sectors, and therefore CO2 emissions, in those countries. This will...

Both the mining and the burning of coal is pollutive, so one might expect to observe taxes on coal production and consumption. Yet several countries in Western Europe subsidize coal production, and most East European countries subsidize coal consumption. The first part of this paper shows that...

This paper looks at the interplay between human capital and innovation in the presence of climate and educational policies. Using recent empirical estimates, human capital and general purpose R&D are introduced in an integrated assessment model that has been extensively applied to study the...

The paper analyses the problem of optimal taxation in oligopoly when environmental degradation induced by the industry production process feeds back into market demand. The main assumption is that economic agents and the policy-maker care about the environment only because its degradation...

We analyse how, in representative democracies, income distribution influences the stringency of environmental policy and economic growth. Individuals (who differ in abilities) live for two periods, working when young and owning capital when old. Externalities are caused by a polluting factor....

This Paper explores the relationship between environmental protection and international capital movements, when tax policy is endogenous (through voting). A two-period general equilibrium model of a small open economy is specified to compare the effects of two different constitutions (commitment...

We derive conditions of individual preferences and technology that give rise to a negative correlation between income inequality and environmental protection. We present a class of models (which captures a static model as well as an overlapping-generations model) in which individuals differ in...
