We derive the optimal contributions to global climate policy when countries differ with respect to income level and pollution intensity. Countries' growth rates are determined endogenously, and abatement efficiency is improved by technical progress. We show that country heterogeneity has a...

Environmental policy affects the distribution of market shares if intermediate goods are differentiated in pollution intensity. When innovations are environmental friendly, a tax on emissions skews demand towards new goods, which are the most productive. In this case along a balanced growth path...

This paper presents a two-sector green endogenous growth model to explore a mechanism that explains why carbon-intensive capital is not necessarily shut down during transition to a green economy. Without accumulating clean capital to offset carbon emissions, a tightening of climate regulation...

The energy transition from fossil fuels to alternative energy sources has important consequences for technological change and resource extraction. We examine these consequences by incorporating a non-renewable resource and an alternative energy source in a market economy model of endogenous...

This doctoral thesis, organized in three self-contained chapters, provides an analysis of the economic effects associated with the extraction of natural resources and the transition from an economy based on fossil fuel use to an economy relying primarily on renewable energy sources. Chapter 1...

In this paper, we study the implications of assuming different technologies for physical capital accumulation and consumption. More precisely, we assume that physical capital accumulation is relatively more energy-intensive than consumption. We conclude that this hypothesis, together with the...

This paper studies the possibilities of technical progress to deal with the growth limit problem imposed by the usage of non-renewable energy resources, when physical capital production is relatively more energy-intensive than consumption. In particular, this work presents the conditions under...

It is often argued that policies designed to protect the environment may harm economic growth. Moreover, if introduced unilaterally by a given country, they may reduce the competitiveness of domestic firms. These arguments are generally based on the assumption that environmental protection has...

We provide steps towards a welfare analysis of a two-country endogenous growth model where a relatively small follower absorbs part of the knowledge generated in the leading country. To solve a suitably defined infinite-horizon dynamic optimization problem a specialized version of the Pontryagin...
