Arbitrary temporal heterogeneity in time of European countries panel model

Abstract : It considers a panel data model for 24 European countries with unobservable multiple interactive effects, which are correlated with the regressors. Grounded on properties of the traditional micro-economic theory of production, the arbitrary temporal heterogeneity in time with a factor structure is fit to the Cobb-Douglas stochastic distance frontier with multiple inputs/multiple outputs model and a semi-parametric approach is applied to parameters estimation. The results show that heterogeneity over time and across the European countries matters. The model distinguished 5 unobserved factors that influence the European industry production. The unobserved common factors have a cyclical behavior with the approximate length of 2 years.
