When pollution damages are stochastic, emissions create financial risks. Pollution levels allowed under Coasian contracts then in...

When economic agents decide their optimal environmental behavior, they have to take into account non continuos evolutionary trends and irreversible changes characterising environmental phenomena. Given the still non perfect biophysical and economic knowledge, decisions have to be taken in an...
