We analyze weight and fat percentage measurements of respondents in an online general population panel in the Netherlands, collected using wireless scales, with an average frequency of 1.6 measurements per week. First, we document the existence of a weekly cycle; body mass is lowest on Fridays...

Each week, the Dutch Postcode Lottery (PCL) randomly selects a postal code, and distributes cash and a new BMW to lottery participants in that code. We study the effects of these shocks on lottery winners and their neighbors. Consistent with the life-cycle hypothesis, the effects on winners’...

Interdependent preferences generally imply Pareto inefficiency. For a general demand system, we provide a characterization of Pareto improvements. For a prominent parametric specification, the Linear Expenditure System, we characterize in detail the welfare loss associated with interdependent...

In the first part of this paper, the authors derive explicit expressions for the direct utility functions, conditional demand equations, and concavity conditions in both price/income and quantity space for the demand system introduced by Hausman and Ruud (1984). These results are then used in an...
