We consider a simple model of competition under moral hazard with constant return technologies. We consider preferences that are not separable in effort: marginal utility of income is assumed to increase with leisure, especially for high-income levels. We show that, in this context, Bertrand...

The paper is concerned with the empirical modelling of domestic demand for energy in the United Kingdom at the level of the individual household (most previous British work has used aggregate time-series data). The paper develops a two-stage budgeting model of the household's demand for energy...

In this paper we examine the link between wage inequality and consumption inequality using a life cycle model that incorporates household consumption and family labor supply decisions. We derive analytical expressions based on approximations for the dynamics of consumption, hours, and earnings...

Many of the recently developed alternative econometric approaches to the construction and estimation of life-cycle consistent models using individual data can be viewed as alternative choices for conditioning variables that summarise past decisions and future anticipations. By ingenious choice...

This Paper uses panel data on household consumption and income to evaluate the degree of insurance to income shocks. Our aim is to describe the transmission of income inequality into consumption inequality. Our framework nests the special cases of self-insurance and the complete markets...

How does firm entry affect innovation incentives and productivity growth in incumbent firms? Micro-data suggests that there is heterogeneity across industries - incumbents in technologically advanced industries react positively to entry, but not in laggard industries. To explain this pattern, we...

We present identification and estimation results for the “collective” model of labour supply in which there are discrete choices, censoring of hours and nonparticipation in employment. We derive the collective restrictions on labour supply functions and contrast them with restrictions...

In this paper we develop the collective labour supply framework to allow for corner solutions and nonparticipation in employment.We derive conditions for the complete non parametric identification of individual preferences.We extend our results to allow for unobserved heterogeneity and show...

A model is developed that allows for a lay-off rate and a job arrival rate in the intertemporal choice of consumption and labor market state. The identification of such a model is established without recourse to dynamic programming solutions and the minimum date requirements for estimation are...

In this paper we extend the "collective" model of labour supply developed by Chiappori (1988) to allow for discrete choices, censoring and nonparticipation in employment. We derive the collective restrictions on labour supply functions that we contrast with restrictions implied by the usual...
