Price Uncertainty, The Competitive Firm and the Dual Theory of Choice Under Risk

Abstract: This paper undertakes an analysis of the competitive firm facing output price uncertainty based on Yaari's dual theory of choice under risk. The axiomatic foundation of Yaari's non-expected utility approach permits the formulation of a preference functional which is linear in profit but non-linear in distribution. Yaari's approach allows seperation of the firm's attitude towards risk from its attitude towards wealth and is consistent with experimental evidence on decision-making under uncertainty. In Yaar's dual theory the linearity in profit of the preference funcional stems from a constant marginal utility of wealth and is compatible with either risk aversion or risk inclination. This appealing feature of the dual theory allows us (1) to obtain a characterization of output and input decisions of firms which , unlike the von Neumann-Morgenstern theory of the firm, is in comformity with the main results of the theory of the firm under certainty; (2) to find intuitive comparative statistics effects of increases in risk and risk aversion; (3) to define the profit function for a firm with dual theoretic preferences and show how Hotelling's lemma can be applied to find the firm's output supply and input demand functions.

Keywords: theory of the firm; risk; risk aversion; increase in risk; non-expected utility model; duality and the profit function. (search for similar items in EconPapers)
