This paper develops an index for comparing the productivity of groups of operating units in cost terms when input prices are available. In that sense it represents an extension of a similar index available in the literature for comparing groups of units in terms of technical productivity in the...

In this study Malmquist productivity indexes are used to evaluate the performance of acute hospitals in the UK over the period after the introduction of the internal market in the National Health Service in 1991. The indexes are computed using nonparametric programming, known as Data Envelopment...

The purpose of conventional Data Envelopment Analysis (DEA) is to evaluate the performance of a set of firms or Decision-Making Units using deterministic input and output data. However, the input and output data in the real-life performance evaluation problems are often stochastic. The...

The free disposal hull (FDH) models are used as an alternative to data envelopment analysis (DEA) models for performance measurement and efficiency assessment. The conventional FDH models are used to evaluate the performance of a set of firms or decision-making units (DMUs) using deterministic...

Recently Leleu [A linear programming framework for free disposal hull (FDH) technologies and cost functions: Primal and dual models] presented a linear model for assessing the FDH-cost function with various returns to scale assumptions. He stated that economic inefficiency can be computed as the...

This paper describes an attempt to evaluate cost efficiency in UK university central administration. The funding councils of higher education institutions have progressively evolved elaborate systems for measuring university performance in teaching quality and research. Indeed, funding of...
