Rationality places strong restrictions on individual consumer behavior. This paper is concerned with assessing the validity of the integrability constraints imposed by standard utility maximization, arising in classical consumer demand analysis. More specifically, we characterize the testable...

Berkson errors are commonplace in empirical microeconomics and occur whenever we observe an average in a specified group rather than the true individual value. In consumer demand this form of measurement error is present because the price an individual pays is often measured by the average price...

We develop a model of demand where consumers trade-off the utility of consumption against the disutility of expenditure. This model is appropriate whenever a consumer's demand over a strict subset of all available goods is being analyzed. Data sets consistent with this model are characterized by...

Abstract Standard economic models predict that individuals smooth consumption over the life cycle. In contrast, there exists controversial empirical evidence showing that consumption declines at retirement. This paper investigates whether there is evidence for this so-called Retirement...
