“…It is based on a pair of input-oriented efficiency measures using a nonparametric frontier framework, very much in line with the output-oriented plant capacity utilisation measure that is based on a couple of output-oriented efficiency measures. In a recent study, Kerstens and Shen ( 2021 ) use these plant capacity concepts to measure hospital capacities in the Hubei province in China during the outbreak of the COVID-19 pandemic. Using the medical literature indicating that mortality rates increase with high capacity utilization rates leads to the preliminary conclusion that this relatively new input-oriented plant capacity concept correlates best with mortality.…”

The purpose of this contribution is to compute the popular Malmquist productivity index while adding a component representing plant capacity utilisation. In particular, this is—to the best of our knowledge—the first empirical application estimating both input- and output-oriented Malmquist productivity indices in conjunction with the corresponding input- and output-oriented plant capacity utilisation measures. Our empirical application focuses on a provincial data set of tourism activities in China over the period 2008–2016. The results contain the output- and input-oriented Malmquist productivity indices, some Spearman rank correlations between both, a t-test whether these indices differ from unity, and some bootstrapping analysis. Supplementary Information The online version contains supplementary material available at 10.1007/s10479-022-04771-8.

“…These various SR and LR O-oriented and I-oriented plant capacity measures have been empirically applied to measure hospital capacity in the Hubei province in China during the recent COVID epidemic in Kerstens and Shen (2021). Though the sample is limited, the empirical evidence indicates that the LR I-oriented plant capacity notion correlates best with the observed mortality.…”

This study investigates the existence of solutions for the key plant capacity utilisation (PCU) concepts using general nonparametric technologies. This is done via a theoretical review of existing and some new PCU concepts. Focusing on short-run and long-run output-oriented, attainable output-oriented, and input-oriented PCU notions, we first investigate the existence of solutions at the firm level. Under mild axioms, this question regarding the existence of solutions for these PCU concepts at the firm level is affirmatively answered under variable and constant returns to scale as well as under convex and nonconvex assumptions. However, short-run and long-run output-oriented and attainable output-oriented PCU concepts may not be implementable depending on certain conditions. There are no such reservations for the input-oriented PCU. Then, for this same range of PCU concepts, we explore the more difficult question as to the existence of solutions at the industry level. The output-oriented and attainable output-oriented PCU exist at the industry level under strict conditions: existence and attainability are interwoven at this level. The industry input-oriented PCU is always feasible at the industry model. This theoretical review is supplemented by a semi-systematic empirical review, and an empirical application. We conclude that input-oriented PCU is clearly the best concept.

“…Most existing research on output-oriented PCU focuses on fisheries and hospitals (see, e.g., Kerstens and Shen (2021) for a selective review). For example, Färe, Grosskopf, and Valdmanis (1989) find that the hospitals in their sample do not operate at full capacity.…”

“…The earlier PCU concepts only focusing on changes in the variable inputs can then be considered as short-run PCU concepts. Kerstens and Shen (2021) empirically adopt these various short-run and long-run inputoriented and output-oriented PCU measures to measure hospital capacity in the Hubei province in China during the recent COVID epidemic. This empirical study indicates that the input-oriented concept of long-run PCU is best associated with observed mortality, despite the limited sample size.…”

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.
