Based upon a critical review of various works about nitrate NPS pollution, we show that in the debate opposing price vs. quantity instruments to regulate pollution, it is possible to refine ? and even more to go past ? the measures which fail to reduce pollution, but at a significantly higher...

We consider an overlapping generations model with environment and an elastic labor supply. In this framework, consumers have to choose between consumption, environmental quality, and leisure. We show the existence of both deterministic cycles and indeterminacy. In contrast to previous results,...
