We study a dynamic carbon pollution model where carbon accumulates both inside a nonrenewable and a renewable reservoir with a constant regeneration rate. Two primary energy sources are available: a cheap exhaustible fossil fuel (coal) and an expensive clean energy alternative (solar). To avoid...

The paper considers an endogenous growth model with climate change as well as three R&D sectors dedicated to energy, CCS (Carbon Capture and Storage) and backstop efficiency. First, we characterize the set of decentralized equilibria: a particular equilibrium is associated with any vector of...

We develop a stochastic endogenous growth model involving a non-renewable resource, in which innovation arrivals are governed by a non-stationary Poisson process. Using a CRRA analytical example, we characterize the optimal trajectories of the model and analyze the effects of uncertainty in the...

In this paper we analyze the dynamic implications of recycling for resource use, the level of economic activity and the long-run development of the economy. In contrast to former approaches, we take explicit account of the circulation of matter in the economy. We consider virgin resources and...
