| The influence of socioeconomic variables on nutrient intake is studied using nonparametric procedures that admit estimation of multivariate functions. The analysis indicates a nonlinear relation between intake, age, education, and income. Specifically, intake rises with income reaching an inflection point beyond which it is essentially flat. Socioeconomic variables influence intake primarily at lower income levels. Nonparametric procedures prove useful in avoiding ad hoc specifications that would fail to uncover these findings. |

| In the presence of uncertainty and irreversibility, dynamic decision problems should not be solved using expected net present value analysis. The right to delay a decision can be valuable. We show that the value of this right equals Arrow and Fishers (1974) quasi-option value. In a discrete model we show how to derive quasi-option value using methods from finance, methods that remove altogether the need to take expected values of future stochastic variables. Two main findings are presented. First, if the stochastic dynamic process underlying the problem is known, the Arrow and Fisher and Henry (1974) result that improper use of net present value leads to too much early development, is correct. Second, if the process is not known perfectly, their... |
