“…6 Caseload, consisting of pending and new cases, is included as an input in Schneider (2005) and Nissi and Rapposelli (2010), based on the argument that performance will be underestimated if the workload is a binding upper bound on utilization efficiency. This is, however, only an effect of the sticky nature of the inputs, because a lower workload can be compensated by less input to achieve higher efficiency, as argued by Mattsson et al (2018). Using caseload as an input may also introduce bias based on poor performance (through backlogging of demand) and/or lack of resources in previous periods (Santos and Amado 2014).…”

Judicial courts form a stringent example of public services using partially sticky inputs and outputs with heterogeneous quality. Notwithstanding, governments internationally are striving to improve the efficiency of and diminish the budget spent on court systems. Frontier methods such as data envelopment analysis are sometimes used in investigations of structural changes in the form of mergers. This essay reviews the methods used to evaluate the ex post efficiency of horizontal mergers. Identification of impacts is difficult. Therefore, three analytical frameworks are applied: (1) a technical efficiency comparison over time, (2) a metafrontier approach among mergers and non-mergers, and (3) a conditional differencein-differences approach where non-merged twins of the actual mergers are identified by matching. In addition, both time heterogeneity and sources of efficiency change are examined ex post. The method is applied to evaluate the impact on efficiency of merging the Swedish district courts from 95 to 48 between 2000 and 2009. Whereas the stated ambition for the mergers was to improve efficiency, no structured ex post analysis has been done. Swedish courts are shown to improve efficiency from merging. In addition to the particular application, this work may inform a more general discussion on public service efficiency measurement under structural changes, and their limits and potential.

“…Finally, Mattsson, Månsson, Andersson, and Bonander (2018) incorporate the potential heterogeneity between the output variables by a weighting based on differences in spent resources between the 14 categories, employ the super-efficiency model to eliminate outliers, and calculate the output-oriented Malmquist productivity index by applying a nonparametric frontier technology to evaluate the efficiency and productivity of Swedish district courts from 2011 to 2015: they obtain a 1.7% average productivity decline per year.…”

This contribution investigates the effects of horizontal mergers and acquisitions on the plant capacity utilisation of the Swedish district courts over the periods 2000-2017. More specifically, we empirically demonstrate the decomposition of input-oriented and output-oriented technical efficiency by incorporating several concepts of plant capacity utilisation. Moreover, we also explore the impact of convexity on input-oriented and output-oriented measures of plant capacity in the short-run scenario in an attempt to discover the potential rationale behind the merger wave. To the best of our knowledge, we are the first to assess horizontal mergers by employing plant capacity utilisation concepts. The results indicate that the horizontal mergers improve capacity utilisation. Furthermore, the nonconvex frontier method provides a more conservative estimate of plant capacity changes of this merger wave.

“…In the South African context, a recent study by Myeki and Temoso (2019) uses DEA to examine efficiency of public universities. Apart from the fact that the model has been widely utilised in the public sector where outputs are not sold on the market (Mattsson et al 2018), Myeki and Temoso (2019) justify their primary preference for DEA based on multiple performance indicators inherent with public universities in South Africa. In the view of Johnes and Tone (2017), DEA is very useful in cases where there is a multiplicity of inputs used to produce a multiplicity of outputs, and where market prices are not available.…”

“…Furthermore, unlike parametric models DEA does not need an assumption of a functional form linking inputs to outputs and the distributional assumption of the error term (Johnes and Tone 2017). One of the main limitations of the DEA technique is its deterministic nature, and therefore this technique is referred to as a non-statistical method (Mattsson et al 2018). Resampling techniques such as the bootstrap procedure suggested by Simar and Wilson (1998) can help with this issue to some degree.…”

This article seeks to assess the efficiency of 23 South African public universities using a Data Envelope Analysis (DEA) model for the period 2009-2016. A recent study on this subject matter found a decline in the average TE score of the South African public universities from 83 per cent in 2009 to 78 per cent in 2013. However, the study did not account for non-academic staff among other input variables that are assumed to potentially influence performance outcomes of the universities. We believed that a biased conclusion on the subject matter is likely if academic staff are assumed to dominate efficiency of public universities in South Africa, while the effort of nonacademic staff is not considered. In this respect, our model incorporates both academic and nonacademic staff as input variables among others. Our findings show that over the study period 2009-2016 the average Technical Efficiency (TE) of the South African public universities increased from 91 per cent to 95 per cent. For this result in particular, we deduce that in assessing efficiency of South African public universities, academic and non-academic staff can be deemed as mutually inclusive variables and therefore, neglecting either of the two can lead to biased estimated average TE scores. In addition to this empirical contribution, we also estimate scale and pure efficiency. Our findings show that on average South African public universities are relatively Nkohla, Munacinga, Marwa, Ncwadi A non-parametric assessment of efficiency of South African public universities 159 better off in scale efficiency (at 97%) as compared to pure technical efficiency (at 96%). The efficiency levels provided in this study can be used as performance benchmarks for identifying potential improvements required to reach a satisfactory level of efficiency.
