We assess the willingness to pay (WTP) for eyeglasses in an adult population in rural Burkina Faso using a variant of the Becker-DeGroot-Marschak (BDM) method. We combine the BDM approach with video and deferred payment options to analyze the role of information and liquidity constraints....

The ability to uncover preferences from choices is fundamental for both positive economics and welfare analysis. Overwhelming evidence shows that choice is stochastic, which has given rise to random utility models as the dominant paradigm in applied microeconomics. However, as is well known, it...

This paper critically discusses the standard concept of hierarchical preferences, which presupposes that a stable system of higher- and lower-order preferences exists, wherein the former contains an individual's fundamental purposes and values, while the latter guides everyday choices. It is...

With few exceptions, today's retailers sell products across multiple categories. One strategic consideration of such retailers is product location, which determines how easy or difficult different categories are for customers to access. For example, grocery or department stores determine which...

Studies show that consumers are often unaware of the price of their purchases. We examine if such ignorance may be willful. We develop a model entailing consumers who may feel conflicted about spending – some people have an inherent preference for overspending (“spendthrifts”). We show...

Considerable evidence shows that people have optimistic beliefs about future out- comes. I present an axiomatic model of wishful thinking (WT), in which an endowed alternative, or status quo, influences the agent's beliefs over states and thus induces such optimism. I introduce a behavioral...

An agent makes consumption choices in multiple periods. Choice objects vary in type and quality; objects of the same type are inter-temporal substitutes. The current choice set is informative about the distribution over future choice sets. Thus, the presence of unchosen alternatives may...

It is often assumed (for analytical convenience, but also in accordance with common intuition) that consumer preferences are convex. In this paper, we consider circumstances under which such preferences are (or are not) optimal. In particular, we investigate a setting in which goods possess some...

We consider optimal consumption and portfolio investment problems of an investor who is interested in maximizing his utilities from consumption and terminal wealth subject to a random inflation in the consumption basket price over time. We consider two cases: (i) when the investor observes the...
