The authors study labor supply of elderly couples by means of a collective model. The model allows individuals to enjoy leisure more (or less) in company of their spouse (complementarity/ externalities in leisure). Preferences and the intra-household bargaining process are identified by using...

The implementation of Gary Becker's (1965) time allocation model is hampered by the fact that values of the different time uses are usually not observed. In practice, one often assumes that the value of time is uniform across time uses by using market wages. This approach implies a fundamental...

We provide a nonparametric 'revealed preference' characterization of rational household behavior in terms of the collective consumption model, while accounting for general individual preferences that can be non-convex. Our main result is the Collective Afriat Theorem, which parallels the...

We apply the collective consumption model of Browning et al. (2010) to analyse economic well-being and poverty among the elderly. The model focuses on individual preferences, a consumption technology that captures the economies of scale of living in a couple, and a sharing rule that governs the...

We propose a collective labor supply model with household production that generalizes a model of Blundell, Chiappori, and Meghir (2005). Adults' preferences depend not only on own leisure and individual private consumption of market goods. They also depend on the consumption of domestic goods,...

There is a general interest in ranking performances (e.g., in sports or policy) that essentially implies aggregating several performance dimensions. The usual approach considers a “cardinal†linear weighting of the different single-dimensional performance indicators. The authors...

Robust Rankings of Multidimensional Performances: An Application to Tour de France Racing CyclistsDr. Knut M. Wittkowski (The Rockefeller University) pointed out that his u-score given in Equation 3 of Wittkowski (2003) and Equation 3 in Wittkowski, Lee, Nussbaum, Chamian, and Krueger (2004) is...
