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...

How much income would a woman living alone require to attain the same standard of living that she would have if she were married? What percentage of a married couple`s expenditures are controlled by the husband? How much money does a couple save on consumption goods by living together versus...

This paper proposes a joint model of tobacco consumption and mortality over the life-cycle. The decision to smoke is a trade off between current utility derived from smoking and a mortality risk increasing with age. Individuals with a longer potential life expectancy have more incentive to cut...

Euler equation estimation of intertemporal consumption models requires many, often unverifiable assumptions. These include assumptions on expectations and preferences. We aim at reducing some of these requirements by using direct subjective information on respondents’ preferences and...

This paper studies the effect of the HIV/AIDS epidemic on saving behaviour. Two important characteristics of HIV result in opposing forces on savings: mortality increases, which reduces savings, and long-term illness risk increases, which enhances savings. We use a two period life-cycle model...

Counselling agencies assist borrowers in financial difficulties by administering repayment plans, the so-called debt management plans (DMPs).  In this paper, we use unique administrative data from a major credit counselling agency in the UK to analyze the determinants of debt repayment...

The paper explores how repeated revisions of consumption plans increase long-run utility. If agents value present anticipations of future consumption, some revisions may be viewed as a benign form of self-delusion. We consider a minimal generalization of the Samuelson discounted utility model to...

Consider a finite data set where each observation consists of a bunde of contingent consumption chosen by an agent from a constraint set of such bundles.  We develop a general procedure for testing the consistency of this data set with a broad class of models of choice under risk and under...

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...

We identify necessary and sufficient conditions under which a finite data set of price vectors and consumption bundles can be rationalized by a weakly separable utility function.  Our result could be understood as a generalization of Afriat's Theorem.
