简介 |
<p>This paper studies uniform inference in a linear panel data model when the slope coefficients may exhibit heterogeneity over both the individual and time dimensions and they can be correlated with the regressors. We propose a generalized fixed effects (GFE) estimation procedure to estimate the model under suitable identification restrictions. To establish the asymptotic properties of the GFE estimators, we invert a number of large dimensional square matrices by approximating them with quasi-Kronecker structured matrices. We establish the asymptotic normality of our GFE estimators and show that their convergence rates depend on the unknown degree of parameter heterogeneity. To make a uniform inference on the common slope component, we propose a novel triple-bootstrap procedure and a hybrid procedure to estimate the asymptotic variance.</p> |
