The problem of non-renewable energy resources in the production of physical capital

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 which energy-saving technologies can sustain long-run growth, although energy is produced by means of non-renewable energy resources. The mechanism behind that is energy efficiency.Nonrenewable resources, Energy-saving technical progress, Economic growth

Energy Saving Technological Progress in a Vintage Capital Model

Fossil fuel is an essential input throughout all modern economies. The reduced availability of this basic input to production, and the stabilization of greenhouse gases concentration - which requires reductions in fossil fuel energy use - would have a negative impact in GDP and economic growth through cutbacks in energy use. However, this trade-off between energy reduction and growth could be less severe if energy conservation is raised by ernergy saving technologies. Here we study this hypothesis and, in particular, the effect of tax over the energy expenditure of firms as a way to promote investments in energy saving technologies. To this we consider a general equilibrium model with embodied and exogenous energy saving technological progress in a vintage capital framework, where the scrapping rule is endogenous and linear simplifications are eliminated.Environment, Nonrenewable resources, Eneregy, Energy saving,

Capital Accumulation and Non-Renewable Energy Resources : a Special Functions Case

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 possibility of technical progress (in particular, energy-saving technical progress), has important implications on economic growth. This model entails some technical difficulties. However, we provide a full analytical characterization of both short and long-run dynamics usig Gauss Hypergeometric functionsNon-renewable resources, Energy-saging technical progress, Special Functions

Energy Saving Technological Progress in a Vintage Capital Model

Fossil fuel is an essential input throughout all modern economies. The reduced availability of this basic input to production, and the stabilization of greenhouse gases concentration?which requires reductions in fossil fuel energy use?would have a negative impact in GDP and economic growth through cutbacks in energy use. However, this tradeoff between energy reduction and growth could be less severe if energy conservation is raised by energy saving technologies. Here we study this hypothesis and, in particular, the effect of a tax over the energy expenditure of firms as a way to promote investments in energy saving technologies. To do this we consider a general equilibrium model with embodied and exogenous energy saving technological progress in a vintage capital framework, where the scrapping rule is endogenous and linear simplifications are eliminated

A Comparative Study of Energy Saving Technical Progress in a Vintage Capital Model

We analyzed the hypothesis about the effectiveness of energy saving technologies to reduce the trade-off between economic growth and energy preservation. In a general equilibrium vintage capital model with embodied energy saving technical progress, we show that the success of energy saving technologies is questionable in a scenario of decreasing energy supply. Only constant returns to scale, with constant energy supply, yields long run growth

A comparative study of energy saving technical progress in a vintage capital model

We analyze the hypothesis about the effectiveness of energy saving technologies to reduce the trade-off between economic growth and energy preservation. In a general equilibrium vintage capital model with embodied energy saving technical progress, we show that positive growth is only possible if the growth rate of the energy saving technical progress exceeds the decreasing rate of the energy supply

Land Use Dynamics and the Environment

International audienceThis paper builds a benchmark framework to study optimal land use, encompassing land use activities and environmental degradation. We focus on the spatial externalities of land use as drivers of spatial patterns: land is immobile by nature, but local actions affect the whole space since pollution flows across locations resulting in both local and global damages. We prove that the decision maker problem has a solution, and characterize the corresponding social optimum trajectories by means of the Pontryagin conditions. We also show that the existence and uniqueness of time-invariant solutions are not in general guaranteed. Finally, a global dynamic algorithm is proposed in order to illustrate the spatial-dynamic richness of the model. We find that our simple set-up already reproduces a great variety of spatial patterns related to the interaction between land use activities and the environment. In particular, abatement technology turns out to play a central role as pollution stabilizer, allowing the economy to reach a time-invariant equilibrium that can be spatially heterogeneous
