Evidence from English real wages and real land rents for the period 1500-1800 are used to evaluate the impact of temperature and precipitations on under-developed economies. Estimating key parameters of an AK-growth model, we extract Total Factor Productivity (TFP hereafter) shocks and estimate...

This paper surveys the existing Environmental Kuznets Curve studies and discusses to what extent they may be valid and applicable for developing countries. We found that, given the shortcomings in both the theoretical and empirical aspects of the analyses applied to this hypothesis, no...
