“…One variant of this has been implemented below for the case when student number increases are to be prioritised over research output. However, additional models for imposing weights restrictions in estimating efficiencies can be found in Thanassoulis et al (2004) and for imposing alternative preference structures when estimating targets in Thanassoulis and Dyson (1992).…”

As student numbers in the UK's higher education sector have expanded substantially during the last 15 years, it has become increasingly important for government to understand the structure of costs in higher education, thus allowing it to evaluate the potential for expansion and associated cost implications. This study applies Data Envelopment Analysis (DEA) to higher education institutions (HEIs) in England in the period 2000/01-2002/03 to assess the cost structure and the performance of various HEI groups. The paper continues and complements an earlier study by Johnes, Johnes and Thanassoulis (2008), who used parametric regression methods to analyse the same panel data. Interestingly, the DEA analysis provides estimates of subject-specific unit costs that are in the same ballpark as those provided by the parametric methods. We then extend the previous analysis by examining potential cost savings and output augmentations in different HEI groups using several different DEA models. The findings include a suggestion that substantial gains of the order of 20-27% are feasible if all potential savings are directed at raising student numbers so that each HEI exploits to the full not only operating and scale efficiency gains but also adjusts its student mix to maximise student numbers. Finally we use a Malmquist index approach to assess productivity change in UK HEIs. The results reveal that for a majority of HEIs productivity has actually decreased during the study period.

“…Allen et al (1997) and Thanassoulis et al (2004) present a review of the evolution of the incorporation of value judgments by weight restrictions. Angulo Meza and Lins (2002) consider that the addition of weight restrictions is one of the techniques that promote improvement of discrimination in DEA, adding subjective opinions.…”

Economic and socio-environmental performance assessment of beef cattle production systems: a data envelopment analysis (DEA) approach with weight restrictions

et al. 2015

-This study evaluated the performance of 21 beef cattle modal production systems that conduct only the raising phase. These production systems were developed in 21 municipalities in seven Brazilian states. We used two different DEA BCC models, corresponding to different points of view. Firstly we used an economic model that measured the ability of a production system to generate revenue with the preservation of native forest, using labor, capital, and current spending as inputs. The socio-environmental approach, corresponding to the second BCC model, uses the production factor labor as an output. In that model our interest was to assess whether the capital costs generate economic, environmental, and social benefits. Weight restrictions were imposed on the output variables of each model to explain the proposed viewpoints and to avoid inconsistent results. The results pointed out sources of inefficiency in terms of labor with low qualification, and use of bulls of questionable quality, factors that are common in extensive systems. These are some of the major bottlenecks in animal production systems as a whole.

“…However, Halkos et al (2015) notified an extreme case where the contribution of one stage is zero. As explained by Thanassoulis et al (2004) this may not be reasonable. Halkos et al (2015) proposed the weight assurance region (WAR) model to overcome this problem.…”

“…Halkos et al (2015) proposed the weight assurance region (WAR) model to overcome this problem. In addition, the WAR model allows for the incorporating a priori value judgements into the model, such as known information and/or widely accepted beliefs or preferences, and other types of information as described by Thanassoulis et al (2004). The WAR model is an advancement of the original additive two-stage DEA model which can be considered as a special case of the WAR model with no additional information.…”

Investigating bank efficiency in transition economies: A window-based weight assurance region approach

et al. 2017

This paper examines the efficiency of 116 banks for 9 new EU members in Central and Eastern European (CEE) countries over the period [2004][2005][2006][2007][2008][2009][2010][2011][2012][2013][2014][2015]. We employ the Weight Assurance Region (WAR) and we treat deposits as an intermediate variable in a two-stage data-envelopment analysis model. We then expand the WAR model by including a window-based approach to take into account the patterns of efficiency over time. The results indicate a low level of efficiency over the entire period of analysis, especially for Eastern European and Balkan countries rather than Central European countries. Overall, we find that inefficiency in CEE countries is mainly driven by the profitability stage rather than the value added activity stage.
