This paper analyzes the transitional dynamics in a model of economic growth with endogenous technological change and two alternative sources of energy: renewable and non-renewable resources. The conditions for the existence and saddle point property of the steady state are given. Finally, we...

We consider a general equilibrium model in asset markets with a countable set of states and expected risk averse utilities. The agents do not have the same beliefs. We use the methods in Le Van - Truong Xuan (JME, 2001) but one of their assumption which is crucial for obtaining their result...

This paper examines a model of optimal growth where the aggregation of two separate well behaved and concave production technologies exhibits a basic non-convexity. First, we consider the case of strictly concave utility function: when the discount rate is either low enough or high enough, there...

This paper shows that for a time-independent specific tax and a time-independent ad valorem tax that induce the same competitive equilibrium in the Hotelling model of resource extraction, the ad valorem tax yields a higher level of discounted tax revenues than the specific tax. Moreover, given...

The paper presents a synthesis of the economics of exhaustible resources and that of endogenous fertility in an overlapping-generations model. Renewable energy is produced by a backstop, while the consumption good is produced from energy – provided by the backstop or from a stock of...
