In this paper we use a modified Ramsey-Cass-Koopmans model to show that the inverse U-shaped income-pollution relationship may be explained through the declining behavior of the interest rate over time and as income grows. If the problem of the benevolent planner is to implement an environmental...

In this paper we use Copeland and Taylor's model [1994] to show that international trade is always environmental quality improving, under the condition of exogenous pollution taxes. Indeed, we demonstrate that in cases where the marginal disutility of pollution emissions is strictly positive,...

In this paper we use Pindyck's model (2002) to show that the discount rate may play an important role in explaining for the income-pollution pattern observed in the real world. Low levels of income involve high values of discount rate, that are obstacles to the adoption of a pollution abatement...

In this short comment to the paper of Andreoni and Levinson (2001), we show that we are able to explain the shape of the Environmental Kuznets Curve (EKC) without considering to increasingreturns of scale in pollution abatement technology, but simply making explicit that the marginal disutility...
