Abstract
 
In this paper we propose a unified framework for accommodating both time and cross-section dependence in modelling technical efficiency in stochastic frontier models.  In particular, we adopt the multi-step procedure advanced by Bailey et al. (2013)  within the non linear panel data model advanced by Kapetanios et al. (2013, KMS). This extended KMS approach enables us to deal with both weak and strong forms of cross section dependence by introducing exogenously driven common factors and an  endogenous threshold selection mechanism. Using the dataset of 26 OECD countries over the period 1970-2010, we provide the satisfactory estimation results for the production  technology parameters and the associated efficiency ranking of individual countries. We find positive spillover effect on efficiency, supporting the hypothesis that knowledge spillover is more likely to be induced by technological proximity. Furthermore, our approach enables us to identify efficiency clubs endogenously in the stochastic frontier analysis.
