In presence of panel data, technical efficiency is used to compare the performances of Decision-Making Units (DMUs). The novelty of this paper is the consideration of the dependence between the two error terms in the case of panel data and the introduction of time effect models in the Stochastic...

This paper studies asymptotic theory for a nonstationary panel autoregressive model when cross-sectional dimension (n) and time dimension (T) are large. We considers the nonstationary case in the presence of both cross-sectional and time fixed effects, which is not investigated in existing...

In this paper, we develop tests for structural change in cointegrated panel regressions with common and idiosyncratic trends. We consider both the cases of observable and nonobservable common trends, deriving a Functional Central Limit Theorem for the partial sample estimators under the null of...
