摘要

The starting point for this paper is the realization that the utility function used in the expected utility (EU) model is actually an indirect utility function. Nearly every application of the EU model in economics begins with a utility function that is continuous and concave over profit, income or wealth; that is, money is treated as the root of all happiness. The present paper considers preferences that depend on both income and a discrete factor, where the realization of this discrete factor depends stochastically on income. This model begins with the basic EU format for preference over both income and status. It then considers behaviour under a reduced-form model over income alone that is consistent with the S-shaped curve having both concave and convex segments. This status model further relates to behaviourally based safety rule models for critical income levels and suggests considerable heterogeneity of risk attitudes among individuals..
