Bayesian treatments for panel data stochastic frontier models with time varying heterogeneity

Liu, Junrong; Sickles, Robin C.; Tsionas, E. G. - In: Econometrics 5 (2017) 3, pp. 1-21

This paper considers a linear panel data model with time varying heterogeneity. Bayesian inference techniques organized around Markov chain Monte Carlo (MCMC) are applied to implement new estimators that combine smoothness priors on unobserved heterogeneity and priors on the factor structure of...

Bayesian approach to disentangling technical and environmental productivity

Malikov, Emir; Kumbhakar, Subal C.; Tsionas, Efthymios G. - In: Econometrics 3 (2015) 2, pp. 443-465

the traditional (desirable-output-oriented) technical productivity and the undesirable-output-oriented environmental, or … so-called "green", productivity. To measure the latter, we derive a Solow-type Divisia environmental productivity index … which, unlike conventional productivity indices, allows crediting the ceteris paribus reduction in undesirable outputs. Our …
