Analysis of efficiency in multi-period systems: an application to performance evaluation in education

Data envelopment analysis (DEA) is a non-parametric method for efficiency and performance analysis of decision making units. The paper deals with production systems where decision making units are described by their inputs and outputs in several consecutive periods. The paper presents multi-period DEA models that allow evaluation the efficiency of DMUs within the whole production chain. Efficiency and super-efficiency DEA models for multi-period systems are formulated and illustrated on a case study. The study consists in analysis of research and teaching performance of Czech economic faculties in four years period from 2007 until 2010. The model considers two inputs (number of academic employees and labour costs), two outputs for teaching efficiency (number of students and number of graduated) and the number of publications in various important categories and the number of RIV points for research efficiency.
