The elegant economic picture of rational consumers achieving Pareto optimality through trade in decentralized self-organized markets is blurred by market imperfections and choices inconsistent with consumer self-interest. Behavioral economics has documented these errors in choice, and considered...

Economists since the days of Adam Smith and Jeremy Bentham have traditionally viewed consumers as driven by relentless and consistent pursuit of self-interest, with their choices in the marketplace providing all the measurements needed to reveal their preferences and assess their well-being....

A common problem in applied economics is to determine the impact on consumers of changes in prices and attributes of marketed products as a consequence of policy changes. Examples are prospective regulation of product safety and reliability, or retrospective compensation for harm from defective...

We describe two methods for correcting an omitted variables problem in discrete choice models: a fixed effects approach and a control function approach. The control function approach is easier to implement and applicable in situations for which the fixed effects approach is not. We apply both...

This paper considers discrete choice, with choice probabilities coming from maximization of preferences from a random utility field perturbed by additive location shifters (ARUM). Any ARUM can be characterized by a choice-probability generating function (CPGF) whose gradient gives the choice...

We consider demand systems for utility-maximizing consumers facing general budget constraints whose utilities are perturbed by additive linear shifts in marginal utilities. Budgets are required to be compact but are not required to be convex. We define demand generating functions (DGF) whose...

This expository paper describes the factors that contribute to failure of health insurance markets, and the regulatory mechanisms that have been and can be used to combat these failures. Standardized contracts and creditable coverage mandates are discussed, along with premium support, enrollment...

This paper investigates whether subjective expectations about future mortality affect consumption and bequests motives. We estimate a dynamic life-cycle model based on subjective survival rates and wealth from the panel dataset Asset and Health Dynamics among Oldest Old. We find that bequest...

Testing life-cycle models and other economic models of saving and consumption at micro level requires knowledge of individuals' subjective believes of their mortality risk. Previous studies have shown that individual responses on subjective survival probabilities are generally consistent with...

The trend towards giving consumers choice about their health plans has invited research on how good they actually are at making these decisions. The introduction of Medicare Part D is an important example. Initial plan choices in this market were generally far from optimal. In this paper, we...
