In a simple conceptual framework, we organize a multitude of phenomena related to the (mis)prediction of utility. Consequences in terms of distorted choices and lower wellbeing emerge if people have to trade-off between alternatives that are characterized by attributes satisfying extrinsic desires and alternatives serving intrinsic needs. Thereby the neglect of asymmetries in adaptation is prop...

The structural consumer demand methods used to estimate the parameters of collective household models are typically either very restrictive and easy to implement or very general and dif cult to estimate. In this paper, we provide a middle ground. We adapt the very general framework of Browning, Chiappori and Lewbel (2007) by adding a simple restriction that recasts the empirical model from a hi...

This paper develops a revealed preference methodology for exploring whether time inconsistencies in household choice are the product of nonstationarities at the individual level or the result of individual heterogeneity and renegotiation within the collective unit. An empirical application to household-level microdata highlights that an explicit recognition of the collective nature of choice al...

Using a unique panel data set from a U.K. credit card company, we analyze the interest rate sensitivity of subprime credit card borrowers. In addition to all individual transactions and loan terms, we have access to details of a randomized interest rate experiment conducted by the lender on existing (inframarginal) loans. For the whole sample, we estimate a statistically significant £3.4 reduct...

Neoclassical economic theory rules out systematic errors in consumption choice. According to the basic view, individuals know what they choose. They are able to predict how much utility an activity or a good produces for them now and in the future and they can maximize their utility. This implies that behavior reveals consistent preferences. This approach makes it impossible to detect and under...

This lecture address the following two key criticisms of the empirical application of revealed preference theory: When the RP conditions do not reject, they do not provide precise predictions; and when they do reject, they do not help characterize the nature of irrationality or the degree/direction of changing tastes. Recent developments in the application of RP theory are shown to have rendere...
