This paper analyses the welfare effects of changes in cross-sectional wage dispersion, using a class of tractable heterogeneous-agent economies. We emphasize a trade-off in the welfare calculation that arises when labour supply is endogenous. On the one hand, as wage uncertainty rises, so does...

Budget constraints are drawn up for annual hours and net pay, typically composed of two linear segments: 'benefit-constrained', where extra work forfeits benefit and 'normal', where extra work is subject to the standard marginal tax rate. There are additional linear segments for those on upper...

This Paper explores the implications of the recent sharp rise in US wage inequality for welfare and the cross-sectional distributions of hours worked, consumption and earnings. From 1967 to 1996 cross-sectional dispersion of earnings increased more than wage dispersion, due to a rise in the...

This paper develops an analytical framework to study consumption and labour supply in a rich class of heterogeneous-agent economies with partial insurance. The environment allows for trade in non-contingent and state-contingent bonds, for permanent and transitory idiosyncratic productivity...

Data on the life-cycle profiles of inequality in wages, earnings, hours worked and consumption contains precious information for answering questions about the ability of households to insure labor market risk and about the sources of this risk. This Paper demonstrates that the choice of whether...

Using the recent EC Commission report `One Market, One Money' as a point of reference, we consider the merits of a single currency in Europe. The main benefit is the reduction in transaction costs, which the report estimates at 0.4% of European Community (EC) GDP (but much less in countries with...

The paper uses a general equilibrium model of regional labor markets, in which national and local factors interact to determine local wages and unemployment; when mobility between regions is obstructed by rent subsidies and controls, unemployment and wage differentials arise. Because...
