We develop a model for decomposing the covariance structure of panel data on firms into a part due to permanent heterogeneity, a part due to differential histories with unknown ages, and a part due to the evolution of economic shocks to the firm. Our model allows for the endogenous death of...

We present a method that accommodates missing data in longitudinal datasets of the type usually encountered in economic and social applications. The technique uses various extensions of missing at random' assumptions that we customize for dynamic models. Our method, applicable to longitudinal...

We test for sorting of workers between and within industrial sectors in a directed search model with coordination frictions. We fit the model to sector-specific vacancy and output data along with publicly-available statistics that characterize the distribution of worker and employer wage...

We study the relation between product quality and worker quality using an economic model that, under certain conditions, provides a direct link between product price, product quality and work force quality. Our measures of product quality are the evolution in the detailed product price relative...

We decompose the real annual full time compensation costs of 1.1 million French workers followed over 12 years into a part that reflects their external opportunity wage and a part that reflects their internal wage rate. Using these components of compensation we investigate the extent to which...

Our empirical analyses distinguish between flows of workers, directly measured, and job creation and destruction, again, directly measured. We use a representative sample of all French establishments for 1987 to 1990. Our most important findings are that (1) annual job creation can be...

We use longitudinal individual wage and employment data for young people in France and the United States to investigate the effect of intertemporal changes in an individual's status vis-…-vis the real minimum wage on employment transition rates. We" find that movements in both French and...

We study a longitudinal sample of over one million French workers and over 500,000 employing firms. Real total annual compensation per worker is decomposed into components related to observable characteristics, worker heterogeneity, firm heterogeneity and residual variation. Except for the...

In this paper we model the determinants of firm level wages and employment explicitly allowing for firm and worker heterogeneity. Our firms have three types of workers (cadres, skilled and unskilled) and may explicitly choose from among three distinct contracting regimes (strong form efficiency,...

We use longitudinal individual wage and employment data in France and the United States to investigate the effect of changes in the real minimum wage on an individual's employment status. We find that movements in both French and American real minimum wages are associated with mild employment...
