Efficiency of academic sports clubs operating in higher educationIn the article, the efficiency of 29 academic sports clubs in 2017 was measured using the NR-DEA non-radial-efficiency data envelopment analysis model. Two empirical models characterizing two different areas of activity of academic sports clubs were used in the study. The first model M1 fo­cused on club productivity, it includes the number of people practicing in the club and the total number of points obtained in the Polish Academic Championships. The second model M2 focused on club activity, it takes into account the number of organized events and participants taking part in the events. The results obtained show that sports clubs of technical universities were more often effective in terms of productivity than in terms of activity. A different situation occurs in university clubs, which were more often effective in terms of the activity of sports events, sporadically in terms of productivity.

The super-efficiency data envelopment analysis model is innovative in evaluating the performance of crude oil prices’ volatility forecasting models. This multidimensional ranking, which takes account of multiple criteria, gives rise to a unified decision as to which model performs best. However, the rankings are unreliable because some efficiency scores are infeasible solutions in nature. What’s more, the desirability of indexes is worth discussing so as to avoid incorrect rankings. Hence, herein we introduce four models, which address the issue of undesirable characteristics of indexes and infeasibility of the super efficiency models. The empirical results reveal that the new rankings are more robust and quite different from the existing results.
