This study estimates a von Neumann-Morgenstern utility function using market data and microeconometric methods. We investigate the decision whether to purchase insurance against the risk of telephone line trouble in the home. Using the choices of approximately 10,000 residential customers, we determine the shape of the utility function and the degree of risk aversion. We find that risk aversion varies systematically in the population and varies with the level of income and that the observed choice behavior is consistent with expected utility maximization.

We analyze taxpayer choices of return preparation services. We distinguish between two types of nonpaid preparers, six types of paid third parties, and self-preparation. Among other things, we find significant differences in the factors which explain the demand for paid third parties who are and are not able to represent clients before the IRS. Among these factors are increases in IRS audit rates and the frequency of IRS penalties.
