The research interest group in efficiency and productivity analysis comprises academic researchers and research students working on the theory and applications of econometric analysis and mathematical programming models for measuring the relative economic performance of firms and businesses, including banks, government agencies, public bodies such as hospitals and schools, social organisations and whole economies.
The analytical techniques known as data envelopment analysis (which uses mathematical programming) and stochastic frontier analysis (which uses regression analysis) are used to construct relative efficient performance frontiers from performance data on outputs, inputs, costs, revenues and profits assembled for samples of firms, organisations, institutions and economic agents of different kinds that are pursuing similar activities. It is widely used in benchmarking analysis and economic and social regulation of a wide range of business, economic and social organisations. It can be used to measure the effectiveness of policy initiatives for innovation. A major challenge is the careful analysis of what constitutes the outputs of different organizations and institutions, especially where these are operating in non-commercial markets.
Recent work for example has drawn on Professor Weyman-Jones’s role as the accredited consultants’ economic advisor to UK and German regulators: OFGEM and BundesNetzAgentur, the research led the implementation of panel data stochastic frontier analysis for benchmarking of transmission and distribution networks. In other work, Professor Baibing Li, Dr Hailin Liao and their research student Bin Wang (now at the World Bank) investigated how the performance of US industry changed as the revolution in ICT evolved. Drs Karligash Glass and Tony Glass working with Professor Robin Sickles analysed the how the productivity performance of EU economies is affected by economic integration amongst neighbouring economies. A wide range of applications ranging from the relative performance of investment funds, banks and financial institutions, all the way through to police services and regulated industries, has been carried out and is on-going. Numerous publications and conference papers have disseminated the group’s work around the world. Two members of the group are among the editors of the most significant journal in the field: Journal of Productivity Analysis.
As well as supporting current researchers in efficiency and productivity analysis, the aims of the EPA-RIG include mentoring and encouraging growth in membership of academics, particularly young researchers new to efficiency and productivity analysis in this expanding field which has increasing theoretical and empirical impact
