This paper considers the problem of estimating a partially linear semiparametric fixed effects panel data model with possible endogeneity. Using the series method, we establish the root N normality result for the estimator of the parametric component, and we show that the unknown function can be...

This paper derives Lagrangian multiplier (LM) tests to jointly test for functional form and spatial error correlation. In particular, this paper tests for linear and log-linear models with no spatial error dependence against a more general Box-Cox model with spatial error correlation....

This paper considers the problem of prediction in a panel data regression model with spatial autocorrelation in the context of a simple demand equation for liquor. This is based on a panel of 43 states over the period 1965-1994. The spatial autocorrelation due to neighboring states and the...
