We model biological invasions as an unintended by-product of capital accumulation. We distinguish three spillover effects: (1) a negative production externality, (2) a negative or positive consumption externality and (3) an increase in the risk of future welfare loss. We also consider the...

A global planning problem is analyzed for extracting an exhaustible resource like oil when resource extraction - the only source for current consumption - also generates additions to the stock of GHGs that influence the likelihood of hitting a threshold representing climate change. We derive...

This paper studies the implications for reserve lifetime and related quantities in a continuous time model of resource extraction under uncertainty. Both the resource price and the extracted amount are assumed to follow stochastic processes. Reserve lifetime is determined by the...
