Several models of intra-household decision making have been suggested in the literature. We present a framework that includes all suggested models and variants as special cases. We derive the theoretical predictions of these models for the relationship between expenditures on goods and the...

In the empirical modelling of demands and labour supply we often lack data on a full set of goods. The usual response is to invoke separability assumptions. Here we present an alternative based on modelling demands as a function of prices and the quantity of a reference good rather than total...

The literature on the characterization of aggregate excess and market demand has generated three types of results: global, local, or 'at a point'. In this note, we study the relationship between the last two approaches. We prove that within the class of functions satisfying standard conditions...

We compare the wage and employment consequences of a job displacement in Belgium and Denmark. These two countries both have generous unemployment insurance schemes but job protection laws vary dramatically between the two. Using comparable data we find that the incidence of displacement and the...

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...
