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...

Eradicating extreme poverty from the face of the earth once and for all is a central goal of the post-2015 development agenda. Without a rapid transition of the world economy to a low-carbon growth path over the next few decades, this ambitious goal will remain elusive. Under current greenhouse...

The paper considers a climate change growth model with three R&D sectors dedicated to energy, backstop and CCS (Carbon Capture and Storage) efficiency. First, we characterize the set of decentralized equilibria: A particular equilibrium is associated to each vector of public tools which includes...

The paper investigates socially optimal patterns of economic growth and environmental quality in a neoclassical growth model with endogenous technological progress. In the model, the environmental quality affects positively not only to utility but also to production. However, cleaner...

We determine the core characteristics of a climate coalition's optimal policies in a dynamic two country directed technical change framework. Unilateral policies alter the structure of production and thereby innovation incentives across countries. Whenever feasible, optimal policies implement...

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...

Growth theory is supposed to enhance welfare of the population by raising their per capita output, income and consumption. But, if for that purpose population is reduced, such theory is anti-growth. This paper proves that Solow's growth theory is anti-growth, and that his use of population...

The paper develops an integrated baseline model to assess the trade-offs between the natural environment and economic growth. Consumption growth is considered under welfare and sustainability aspects. The framework features capital accumulation and the sectoral structure of the economy as key...
