We apply the collective consumption model of Browning, Chiappori and Lew- bel (2006) 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...

If decision-makers (DMs) do not always do what is in their best interest, what do choices reveal about welfare? This paper shows how observed choices can reveal whether the DM is acting in her own best interest. We study a framework that relaxes rationality in a way that is common across a...

We study the public policy implications of a model in which agents do not fully internalize all the conscequences of their actions. Such a model uni es seemingly disconected models with behavioral agents. We evaluate the scope of paternalistic and libertarian-parternalistic policies in the light...

This paper contrasts the normative implications of a model of decision- making with endogenous frames to those of choice theoretic models of Bernheim and Rangel (2007, 2009) and Rubinstein and Salant (2008) in which observed choices are determined by exogenous frames or ancillary conditions. We...

We provide a revealed preference analysis of the transferable utility hypothesis, which is widely used in economic models. First, we establish revealed preference conditions that must be satisfied for observed group behavior to be consistent with Pareto efficiency under transferable utility....

Recent insights from the ‘embodied cognition’ perspective in cognitive science, supported by neural research, provide a basis for a ‘methodological interactionism’ that transcends both the methodological individualism of economics and the methodological collectivism of (some) sociology,...

In this paper we axiomatically characterize two recursive procedures for defining a social group.The first procedure starts with the set of all individuals who define themselves as members of the social group, while the starting point of the second procedure is the set of all individuals who are...

Recent work by Kasher and Rubinstein (1997) considers the problem of group identification from a social choice perspective.These authors provide an axiomatic characterization of a liberal aggregator whereby the group consist of those and only those individuals each of which views oneself a...

We consider the problem of ranking sets of objects, the members of which are mutually compatible.Assuming that each object is either good or bad, we axiomatically characterize three cardinality-based rules which arise naturally in this dichotomous setting.They are what we call the symmetric...

By generalizing the standard solution for 2-person games into n-person cases, this paper develops a new solution concept for cooperative games: the consensus value.We characterize the consensus value as the unique function that satisfies efficiency, symmetry, the quasi dummy property and...
