This paper studies the cost effectiveness of climate policy if there are technology externalities. For this purpose, we develop a forward-looking CGE model that captures empirical links between CO2 emissions associated with energy use, directed technical change and the economy. We find the...

This paper examines the macroeconomic effects of an environmental tax reform in a growing economy. A model of endogenous growth based on human capital accumulation is used to numerically simulate the growth effects of different environmental tax reforms and compute their impact on welfare in the...

This paper shows that the assumption of elastic fertility choices represents an unconsidered way of introducing nondegenerate dynamics within an immortal small open economy, facing perfect capital mobility and no adjustment costs associated with capital accumulation, and having a fixed discount...

This paper analyses environmental fiscal policy within a two-sector endogenous growth model with elastic labour supply. Pollution is modelled as a side product of production. The framework allows us to analyse the consequences of an environmental tax on the economic dynamics. Both transitional...

Existing models of open-access resources are applicable to non-storable resources, such as fish. Many open-access resources, however, are used to produce storable goods. Elephants, rhinos, and tigers are three prominent examples. Anticipated future scarcity of these resources will increase...

This paper distinguishes relative risk aversion and resistance to intertemporal substitution in climate risk modelling. Stochastic recursive preferences are introduced in a stylised numeric climate-economy model using preliminary IPPC 1998 scenarios. It shows that higher risk aversion increases...

We incorporate a renewable resource into an overlapping generations model without capital and with quasi-linear preferences. Besides being an input for production the resource serves as a store of value. We characterise the dynamics, efficiency and stability of the steady state equilibria. The...

Climate change is a phenomenon beset with major uncertainties and researchers should include them in Integrated Assessment Models. However, including further dimensions in IAM models comes at a cost. In particular, it makes most of these models suffer from the curse of dimensionality. In this...

This paper proposes different methods to aggregate heterogeneous policies for renewable energy. We compare time-varying indicators built using principal component analysis with average-based indicators. The main goal of the paper is to account for the evolution of both types of policy indicators...
