Impact of an input-output specification on efficiency scores in data envelopment analysis: A banking case study

Popis výsledku v původním jazyce

The paper stresses the importance of making an appropriate specication of inputs and outputs in technical eciency measurement and provides empirical evidence that this initial step of an eciency measurement project should not be underestimated. Oriented on a case study of Slovak commercial banks for the period from 2005 to 2016, the paper explores to what extent dierent input-output specications aect the comparability or congruence of technical eciency scores in a banking application produced by four dierent data envelopment models diering in the eciency measure and orientation. Building on the long-standing controversy in the banking literature about the most appropriate description of banking production, the paper compares technical eciency scores for 9 input-output specications of the intermediation approach, 9 specications of the production-like approaches and 3 network integrated specications. All these specications were empirically applied earlier in the literature. The eciency scores produced by dierent input-output specications and models are confronted by six measures of association or dependence, and their levels are explained in a regression framework. The results attest that the choice of the input-output set is a critical judgemental input to eciency measurement since there is vast diversity in eciency scores of input-output sets coming from dierent approaches but also for input-output sets associated with the same approach. In addition, intermediation input-output specications tend to produce higher eciency scores than production-like specications.
