A key issue in the book is an analysis of the experience with the application of economic instruments, such as charges and tradable discharge permits.
At the level of the firm tradable permits facilitate adaptive management.
Through this effect industry can be partially protected through trade policies that can make a sector a 'quasi non-tradable'.
This may be a realistic representation of the problem if all consumption from converted land and harvesting of wild species are non-tradable commodities.
The technologies and practices discussed, with the exception of soil erosion control, are all tradable goods.
It should not be surprising that groundnut hay became a tradable commodity, highly valued for fattening.
For example, suppose that the common resource were divided such that each country received equal per capita tradable emission rights.
First, approximately two-thirds of the gains from tradable water rights are captured with a spot market alone.
