This paper introduces time-varying grouped patterns of heterogeneity in linear panel data models. A distinctive feature of our approach is that group membership is left unspecified. We estimate the model’s parameters using a “grouped fixed-effects” estimator that minimizes a least-squares...

Sorting, Employment and Wages in multi-worker firms

Proving the folk theorem in a game with three or more players usually requires imposing restrictions on the dimensionality of the stage-game payoffs. Fudenberg and Maskin (1986) assume full dimensionality of payoffs, while Abreu et al. (1994) assume the weaker NEU condition ("nonequivalent...

This paper examines how employer and worker specific productivity shocks transmit to wage and employment in an economy with search frictions and firm commitment. I develop an equilibrium search model with worker and firm shocks and characterize the optimal contract offered by competing firms to...

In this paper, we build a model of earnings dynamics and estimate it on a representative three-year panel, the French Labour Force Survey. We use the model to simulate individual earnings trajectories beyond the period of observation, and to compute permanent income values. We measure the ratio...

We use detailed information on labor earnings and employment from Social Security records to document earnings inequality in Spain from 1988 to 2010. Male earnings inequality was strongly countercyclical: it increased around the 1993 recession, showed a substantial decrease during the 1997-2007...

Dans cette étude, nous proposons un modèle de la dynamique salariale adapté à une estimation à partir de panels courts comme l’enquête Emploi. Nous utilisons le modèle pour simuler des trajectoires individuelles de salaires au-delà de la période d’enquête et calculer des revenus...

In this paper, we document whether and how much the equalizing force of earnings mobility has changed in France in the 1990's. For this purpose, we use a representative three-year panel, the French Labour Force Survey. We develop a model of earnings dynamics that combines a flexible...

Many approaches to estimation of panel models are based on an average or integrated likelihood that assigns weights to different values of the individual effects. Fixed effects, random effects, and Bayesian approaches all fall into this category. We provide a characterization of the class of...
