Abstract: | We formulate and test the hypothesis that expectations regarding changes in future income influences the WTP for environmental goods. For valuation of environmental goods in forests and other habitats in Denmark, we find that both current income and expected changes in future income are significant determinants for preferences. The effect of income on WTP seems to be caused by changes in preferences for environmental attributes rather than by marginal utility of income. The results suggest that to evaluate the distributional impacts of environmental improvements, researchers need a better measure of expected future consumption options than current income. |
