Sata Envelopment Analysis (DEA) of efficiency is highly sensitive to the level of aggregation. Generally as the number of inputs and outputs increase, differences in measured relative efficiency across firms decrease. This paper advocates using the EKS index number formula to aggreagte inputs...

We often present data bank building (output-data calculation) as an only quantitative work. We think that economist should consider the context where his input-data were built, before to use them in his own data bank (we suggest to make an institutional and a bibliometric analysis of the...

In this paper using Data Envelopment Analysis (DEA) we evaluate the influence of national culture on education policy efficiency for 20 OECD countries. For that reason bootstrap techniques have been employed in order to produce biased corrected efficiency scores and confidence intervals are been...
