We model earnings processes allowing for lots of heterogeneity across agents. We also introduce an extension to the linear ARMA model which allows the initial convergence in the long run to be different from that implied by the conventional ARMA model. This is particularly important for unit...

This paper provides an exhaustive characterization of testability and identifiability issues in the collective framework in the absence of price variation; it thus provides a theoretical underpinning for a number of empirical works that have been developed recently. We first provide a simple and...

Household-level data on consumer expenditures underpin a wide range of empirical research in modern economics, spanning micro- and macroeconomics. This research includes work on consumption and saving, on poverty and inequality, and on risk sharing and insurance. We review different ways in...

In this article, we survey the literature on individual earnings dynamics with a particular focus on allowing for pervasive heterogeneity across individuals. We structure the discussion around ARMA processes with nonlinear trends for each individual. We show that allowing for pervasive and...

The authors assess the empirical validity of the life-cycle model using a time series of cross sections and a novel parametrization of preferences. The main findings are as follows: the excess sensitivity of consumption growth to labor income disappears when the authors control for demographic...

The purpose of this paper is to estimate the parameters of household preferences that determine the allocation of goods within the period and over the life cycle, using micro data. In doing so, the authors are able to identify important effects of demographics, labor market status, and other...
