Abstract

This study investigates the optimal use of ‘dirty’ technologies for economic development and when to stop polluting (either temporarily or forever). This question is addressed within a real option framework where three different kinds of options arise: for stopping pollution temporarily or forever and for re-starting. The possibility to shelve a polluting technology temporarily allows for a more conservationist policy. Costs associated with the option of a re-start lead to hystereses effects that complicate empirical cross-country comparisons of environmental policies.
