Abstract: | The paper examines the effects of uncertainty on the relationship btw. comprehensive NNP and sustainable-equivalent consumption. It is shown that the classical identity continues to hold when the discount factor is a stochastic diffusion process taking the form of geometric Brownian motion with drift. Such a result might be useful as a point of departure in classifying the effects that various forms of uncertainty have on the welfare significance of national product. |
