Recent research on earnings dynamics reveals a great deal of heterogeneity in all parameters that govern underlying processes. In particular, there appears to be considerable heterogeneity in the trend, with some workers having a strong positive trend, and other having no trend, or, even a...

All empirical models of earnings processes in the literature assume a good deal of homogeneity. In contrast to this we model earnings processes allowing for lots of heterogeneity between agents. We also introduce an extension to the linear ARMA model that allows that the initial convergence to...

We develop a model for consumption and income that allows for pervasive heterogeneity and co-dependence between the structural parameters. This provides a comprehensive unifying framework to study income and consumption dynamics jointly. We estimate a full set of structural parameters that...

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...
