Are the Laffer curve and the green paradox mutually exclusive?

In this paper, we study the relationship between the Laffer curve and the green paradox in the context of a Ramsey model with endogenous labor supply in which pollution increases consumer demand (through a compensation effect). We find that—in the long run—the conditions under which a Laffer curve and a green paradox emerge are mutually exclusive. Indeed, the Laffer curve exists under a weak compensation effect, while the green paradox requires a strong effect. Also, we find that, in the short run, limit cycles may arise in the presence of a Laffer curve, while they never occur under a green paradox.
