Efficiency Series Papers


The Efficiency Series Papers are issued by the Oviedo Efficiency Group and deal with theoretical and applied issues of efficiency and productivity. The series also includes contributions from researchers who have presented their work at the Permanent Seminar on Efficiency and Productivity as well as invited articles from specialists in the field. The only requisite for a paper to be considered for inclusion in the series is that it not be published in any journal and that it be reviewed by a member of the OEG. Papers should be submitted in English (style) and anyone interested in having their work appear in the Series should contact the Series Coordinator, David Roibás (droibasuniovi.es).
