This paper develops an endogenous growth model featuring environmental externalities, abatement R&D, and market imperfections. We compare the economic performances under three distinct regimes that encompass public abatement, private abatement without tax recycling, and private abatement with...

The purpose of the model developed in the paper is to provide a simple economic framework to address an economic policy question, namely the optimal size of military R&D investment within total public expenditures. To capture the long-run impact of military R&D on the growth rate of the economy,...

This paper studies energy bias in technical change. For this purpose, we develop a computable general equilibrium model that builds on endogenous growth models. The model explicitly captures links between energy, the rate and direction of technical change, and the economy. We derive the...

This paper reviews fundamental concepts in environmental economics and explores theoretical results regarding the choice of the key policy instruments for the control of externalities: taxes, subsidies and marketable permits. The paper explains why today market mechanisms are increasingly being...

We model the value chain of Carbon Capture, transport and Storage (CCS) by focusing on the decisions taking by actors involved in either capture, transport or storage of CO2. Plants emitting CO2 are located along a Salop circle. If these invest in carbon capture facilities, the captured CO2 is...

The paper develops the Basic Climate Economic (BCE) model featuring the core elements of climate economics and climate policy. The BCE model incorporates fossil stock depletion, pollution stock accumulation, endogenous growth, and climate-induced capital depreciation. We first use graphical...

Empirical studies show that pollution is one of the world's most significant causes of premature death. However, despite its importance macroeconomics still largely neglects this negative externality. To fill the gap, we build a model where productivity growth, emissions, mortality and fertility...

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...
