[en]To study the relationship between a Laffer Curve and the Green Paradox, we consider a Ramsey model with endogenous labor supply, where pollution increases the consumption demand (compensation effect). In the long run, the conditions for a Laffer curve and the Green Paradox are mutually exclusive: the curve exists under a weak compensation effect while the paradox under a strong effect. In the short run, limit cycles arise only if a Laffer curve exists but never occur in the case of Green Paradox.[/en]
