Author(s): Taptuk Emre Erkoc,Mehmet Fatih AcarThe purpose of this paper is to estimate technical efficiencies of 123 universities in Turkey between 2009 and 2013 with using Data Envelopment Analysis as well as to investigate the extent to which ownership influences the efficiencies of universities. Overall efficiencies of universities are computed on the basis of certain production models motivated by different sets of input/output. The results of those models, firstly, have shown that public universities in Turkey are performing in unsatisfactory levels although some of them are doing fairly well. Secondly, after employing mean-comparison t-test and Kruskal-Wallis rank procedures, results indicate that efficiency scores are significantly diverging between public and non-profit universities. Accordingly, the ownership seems to matter for the efficiency performances of universities in Turkey, which refers that the non-profit universities are apparently more efficient than their public counterparts. Thirdly, efficiencies of universities are evidently varying from each other concerning the teaching and research output models.
