Abstract
Triggered by concerns about impacts of long-run climatic change the use of dual-rate discounting to evaluate projects and policies has been suggested. Environmental goods should be discounted at a lower rate than conventional consumption goods. We consider the appropriate use of dual-rate discounting for a class of models where environmental amenity values of a stock of resources are built into the utility function. We argue that dual-rate discounting can only be justified either as a pragmatic device for valuation when future prices for environmental goods are unavailable or when consumption goods and environmental goods are not substitutable and relative prices are not well-defined.
