- Abstract
- In this paper we examine the link between wage inequality and consumption inequality using a life cycle model that incorporates household consumption and family labour supply decisions. We derive analytical expressions based on approximations for the dynamics of consumption, hours, and earnings of two earners in the presence of correlated wage shocks, non-separability and asset accumulation decisions. We show how the model can be estimated and identified using panel data for hours, earnings, assets and consumption. We focus on the importance of family labour supply as an insurance mechanism to wage shocks and find strong evidence of smoothing of male

- Abstract
- Most of the empirical literature on consumption behaviour over the last decades has focused on estimating Euler equations. However, there is now consensus that data-related problems make this approach unfruitful, especially for answering policy relevant issues. Alternatively, many papers have proposed using the consumption function to forecast behaviour. This paper follows in this tradition, by deriving an analytical consumption function in the presence of intertemporal non-separabilities, "superior information", and income shocks of different nature, both transitory and permanent. The results provide evidence for durability, and show that people are relatively better at forecasting short-term rather than long-term shocks
