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...

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. I find that precautionary savings are smaller than if they were measured by use of a model economy...

This paper quantifies the macroeconomic implications of the lack of insurance against idiosyncratic labour market risk. I show that in a model economy calibrated to observed individual level data, households make ample use of work effort as a consumption smoothing mechanism. As a consequence,...

I structurally estimate an incomplete markets lifecycle model with endogenous labor supply, using data on the joint distribution of wages, hours and consumption. The model is successful at matching the evolution of both the first and second moments of the data over the lifecycle. The key...

I structurally estimate an incomplete markets life-cycle model with endogenous labor supply using data on the joint distribution of wages, hours, and consumption. The model is successful at matching the evolution of both the first and second moments of the data over the life cycle. The key...

We develop a general equilibrium model of earnings, income and wealth heterogeneity in continuous time. We extend existing analytical and numerical methods to solve the model. We calibrate the model to U.S. data and find that stochastic interest rates provide a mechanism to link earnings, income...

When the challenges of population aging are being debated, the uncertain future of pension systems is a topic of high priority and large controversy. The aim of this chapter is not to provide a “consensus view” on social security and public insurance in aging populations but to put structure...

This paper examines the importance of ex-ante heterogeneity for understanding the relationship between wealth and labor supply when markets are incomplete. An infinite horizon model is estimated where labor supply is indivisible and households are ex-ante heterogeneous in their labor disutility...

This paper applies Canova JAE 1994 methodology to perform a thorough sensitivity analysis for the Aiyagari QJE 1994 economy. This is a calibrated GE model with incomplete markets and uninsurable income risk, designed to quantify the size of precautionary savings and the degree of wealth...
