This paper studies consumption and labor supply in a model where agents have partial insurance and face risk and initial heterogeneity in wages and preferences. Equilibrium allocations and variances and covariances of wages, hours and consumption are solved for analytically. We prove that all...

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 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...

A welfare analysis of unemployment insurance (UI) is performed in a general equilibrium job search model. Finitely-lived, risk-averse workers smooth consumption over time by accumulating assets, choose search effort when unemployed, and suffer disutility from work. Firms hire workers, purchase...

This paper quantifies the size of precautionary savings implied by a dynamic general equilibrium model with heterogeneous agents when explicitly considering the labor supply decision of households. Key parameters as the intertemporal elasticities of substitution of consumption and leisure are...

In 1997 Chancellor Kohl proposed a major pension reform and pushed the law through Parliament explaining that the German PAYG system had become unsustainable. One limitation of the new law -- one that is crucial for our identification strategy -- is that it left the generous pension entitlements...

This paper analyzes the self-identification process and its role in motivation. We build a model of self-confidence where people have imperfect knowledge about their ability, which in most tasks is a complement to effort in determining performance. Higher self-confidence thus enhances...

We propose and test a general equilibrium model in which longer working time and higher labor force participation lead to a fall in unemployment. Longer working hours and higher labor force participation have two direct effects: People have higher incomes and less (leisure) time. This has...

Much of the literature on time inconsistency has studied the external commitment devices that individuals use to address their self-control problems: tying oneself to the mast, staying away from temptation, holding illiquid assets, or "asking controls" from others. This paper, by contrast,...
