The quasi-simplex model makes use of at least three repeated measures of the same variable to estimate its reliability. The model has rather strict assumptions about how various parameters in the model are related to each other. Previous studies have outlined how several of the assumptions of...

We propose a novel procedure, built within a Generalized Method of Moments framework, which exploits unpaired observations (singletons) to increase the efficiency of longitudinal fixed effect estimates. The approach allows increasing estimation efficiency, while properly tackling the bias due to...

In this paper I develop an intertemporal discrete choice model of female labor supply that allows to analyze state dependence and labor supply along the extensive and the intensive margin. Drawing on microsimulation the nonlinearities in the household budget set are captured and thus work...

We analyze the effects of ownership type and concentration on performance of a population of firms in a model large-scale privatization economy. Using specifications based on first-differences and unique instrumental variables, we find that few types of private ownership improve dynamic...
