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...

We develop an equilibrium lifecycle model of education, marriage and labor supply and consumption in a transferable utility context. Individuals start by choosing their investments in education anticipating returns in the marriage market and the labor market. They then match based on the...

This paper analyzes ex ante and ex post moral hazard in car insurance using Dutch longitudinal micro data. We specify a dynamic model of an insuree's dynamic risk (ex ante moral hazard) and claim (ex post moral hazard) choices. We use this model to characterize the heterogeneous dynamic changes...

This paper derives necessary and sufficient conditions for nonparametric transformation models to be (i) correctly specified, and (ii) identified. Our correct specification conditions come in a form of partial differential equations; when satisfied by the true distribution, they ensure that the...

Studies of inequality often ignore resource allocation within the household. In doing so they miss an important element of the distribution of welfare that can vary dramatically depending on overall environmental and economic factors. Thus, measures of inequality that ignore intra household...

In this paper we develop an approach to measuring inequality and poverty that recognizes the fact that individuals within households may have both different preferences and differential access to resources. We argue that a measure based on estimates of the sharing rule is inadequate as an...

We develop a bidimensional matching model under transferable utility, where individuals are characterized by a continuous trait (e.g., socioeconomic status) and a binary attribute (e.g., smoking status).  The model is "truly multidimensional", in the sense that the impact of the traits cannot...

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...
