We investigate the controversial issue whether unemployment is related to productivity growth in the long run, using U.S. data in a framework of infrequent mean shifts. Tests find (endogenously dated) shifts around 1974, 1986, and 1996, system techniques indicate that the shifts are common...

Widowhood and retirement are likely to change the economic environment of elderly households. While retirement primarily changes income and expenditure patterns, widowhood fundamentally changes the structure of the household. Beside high non-monetary cost of losing the partner, resources are no...

This paper combines income and expenditure with time use data to provide a unique picture of the time paths of labour supplies, saving and full consumption for two-adult households over the life cycle. These data are used to test the life cycle model presented in the paper, at the core of which...

Whether couples pool their resources and behave like a unit or spend their income individually is crucial for social and tax policy. In this paper, I provide a test of the income pooling hypothesis using administrative cross-sectional survey data on expenditures and individual incomes of couple...

The availability of quantity information along with expenditure information in some household surveys allows the estimation of price reactions on the basis of unit values. We compare two specifications that have been proposed in this context by Deaton (1990) and Crawford et al. (1997) in order...

Many budget surveys present the interesting features that for a wide range of goods they contain quantity information along with expenditure information, and that the geographical location of households is fairly precise. We take advantage of these features to develop a method for estimation of...

We adopt the collective approach to consumer behavior with egoistic agents, and assume that the household consumption is either private or public. We then show that (i) household demands have to satisfy testable constraints and (ii) some elements of the decision process can be retrieved from...

We evaluate the income elasticity of the aggregate budget share spent on a sub-group of commodities, in a competitive framework, by a continuum of agents having the same income, but heterogeneous behavior described by an "homothetic preferences scaling factor" having a bounded Pareto...
