In this paper we estimate oil and nonoil import demand functions for the United States under the assumption that import prices are uncertain. Both import demand functions are formally derived from an expected utility maximization problem, treating imports as inputs to the technology. The model allows us to test for risk aversion and to assess the impact of uncertainty on the volume of imports, gross output, and the distribution of income. We find that uncertainty leads to a reduction in welfare, imports, and gross output. Moreover, it hurts labor relatively much more than capital. The impact of uncertainty, however, is found to be quite small.

The purpose of this paper is to examine production decisions under output price uncertainty. Using a nonparametric estimation technique to estimate the first four moments of the unknown price distribution and applying duality, we provide a simple empirical framework for the analysis of supply and demand decisions under price uncertainty. The model is used to examine the importance of higher moments in the firm's production decisions and to investigate underlying attitudes toward risk.
