A generalized stochastic frontier system is fitted with unbalanced panel data of Egyptian floor tileries and estimated using OLS, `within', feasible GLS, and maximum likelihood. Hausman tests indicate ...

This article considers the problem of using categorical data from a panel survey in which there is nonrandom nonresponse to estimate gross flows. The methods are illustrated for the case of estimating ...

Tilt-Up Design Systems, LLC — a company that develops integrated project design and construction technology solutions for the site-cast precast (tilt-up) concrete industry — has released a free ...

In this paper we study neural networks and their approximating power in panel data models. We provide asymptotic guarantees on deep feed-forward neural network estimation of the conditional mean, ...
