When, where and how to perform efficiency estimation

Badunenko, Oleg; Henderson, Daniel J.; Kumbhakar, Subal - 2011

In this paper we compare two flexible estimators of technical efficiency in a cross-sectional setting: the nonparametric kernel SFA estimator of Fan, Li and Weersink (1996) to the nonparametric bias corrected DEA estimator of Kneip, Simar and Wilson (2008). We assess the finite sample...

Corporate R&D and firm efficiency : evidence from Europe’s top R&D investors

Kumbhakar, Subal; Ortega-Argilés, Raquel; Potters, Lesley - 2009

The main objective of this study is to investigate the impact of corporate R&D activities on firms' performance, measured by labour productivity. To this end, the stochastic frontier technique is applied, basing the analysis on a unique unbalanced longitudinal dataset consisting of 532 top...
