This paper develops a break detection procedure for the well-known AR(p) linear panel data model with exogenous or pre-determined regressors. The test allows for a structural break in the slope parameters as well as in the fixed effects. Breaks in the latter are not constrained by any type of...

Missing data or missing values are a common phenomenon in applied panel data research and of great interest for panel data unit root testing. The standard approach in the literature is to balance the panel by removing units and/or trimming a common time period for all units. However, this...

We investigate for human capital threshold effects on economic growth dealing with the issue of endogeneity of the threshold variable. We consider two measures of human capital: (i) the education level and (ii) an extended measure of it accounting for the health level. We provide clear-cut...
