“…For some years, e.g. 1999/0 and 2003/4, the congestion of other expenditure is hard to discern from the graphs butTable 2shows that it did exist 15. The discussion in this paragraph and the next mirrors that in[14,[73][74].…”

“…Intuitively, it does seem improbable that such overspending would have reduced the output of congested universities in terms of income from research grants and contracts, and the number of undergraduate and postgraduate awards. However, a possible explanation is that academic staff expenditure might be capturing the effects of an omitted variable such as the effectiveness of management 15 . It is also conceivable that the apparent existence of 'surplus' academic staff in the congested universities could be indicative of institutional inefficiency in a broader sense.…”

The focus of this paper is on the problem of congestion, which refers to a situation where the use of a certain input has increased by so much that output has actually fallen. This problem is explored using the methodological framework proposed by Färe et al. Annual data are examined for a sample of 41 new British universities in the period 1995/6 to 2003/4. These former polytechnics were granted university status in 1992. A widespread problem of congestion is identified. The results reveal that the order in which technical efficiency is decomposed into scale efficiency, congestion efficiency and pure technical efficiency makes a noticeable difference to the amount of congestion identified. The results also clearly indicate that an excessive number of undergraduate students is the largest single cause of congestion in these new universities. The paper concludes by considering the results from the alternative approach to the measurement of congestion formulated by Cooper et al.

The concept of congestion, which is mainly applied in economics, refers to a situation where inputs are overinvested. Many studies have focused on congestion measurement by means of data envelopment analysis (DEA). However, most of the previous investigations only considered the framework of desirable outputs. In fact, firms in the real world unavoidably generate undesirable outputs (such as pollutants or wastes) along with desirable outputs. Therefore, a new scheme is required for measuring congestion in the simultaneous presence of both desirable and undesirable outputs. This paper develops a nonradial efficiency measure for including undesirable outputs into the environmental performance. Based on the proposed model, a new definition and a new approach are presented to deal with congestion in the simultaneous presence of desirable and undesirable outputs. Then, this paper uses the presented method to study the pollutants (waste gas emission and waste discharge) of 31 administrative regions of China. The finding indicates that 7 industries pay attention to the reduction of their pollutants accompanying improvement of their commercial targets. Consequently, they do not show congestion in any input.
