Welcome to the Oviedo Efficiency Group

The Oviedo Efficiency Group (OEG) comprises a group of researchers working in the fields of efficiency and productivity analysis. The Group was created in 1997 by Dr Antonio Álvarez, who led it until 2010 and consolidated its international standing. The international quality of the Group is demonstrated by the large number of articles published in top international journals (more than 50 since 2015) and the invitations to be Associate Editors of Journal of Productivity Analysis and Empirical Economics. In early 2015, the Group began collaborating with the Cluster of Energy, Environment and Climate Change created by the University of Oviedo through the framework of the Campus of International Excellence project. The OEG members have collaborated with top researchers such as Subal Kumbhakar, Peter Schmidt, Knox Lovell, Tooraj Jamasb and Bert Balk, among others. Their research activity has often received financial support from the regional government of Principality of Asturias, the Spanish government and the European Union.

The OEG organized a course titled “The Measurement of Firms’ Efficiency and Productivity” in Madrid (21th-25th May, 2018). The course's main objective was to promote knowledge of advanced techniques in benchmarking (frontier) analysis using a practical, “hands-on” approach. The course was very successful in terms of attendants (more than 40) from both Spain and abroad.
