A generalized measure of technical efficiency

An epsilon-based measure of efficiency in DEA revisited -A third pole of technical efficiency-

In DEA, we have two measures of technical efficiency with different characteristics: radial and non-radial. In this paper we compile them into a composite model called “epsilon-based measure (EBM).” For this purpose we introduce two parameters which connect radial and non-radial models. These two parameters are obtained from the newly defined affinity index between inputs or outputs along with ...

Efficiency Measure by Generalized Fuzzy Data Envelopment Analysis Model

Data envelopment analysis (DEA) is a non-parametric technique to measure the efficiencies of a set of decision making units (DMUs) with common crisp inputs and outputs. In real-world problems, however, inputs and outputs typically have some levels of fuzziness. To analyze a DMU with fuzzy input/output data, previous studies provided the fuzzy DEA (FDEA) model and proposed an associated evaluati...

A Generalized Measure of Riskiness

T paper proposes a generalized measure of riskiness that nests the original measures pioneered by Aumann and Serrano (Aumann, R. J., R. Serrano. 2008. An economic index of riskiness. J. Political Econom. 116(5) 810–836) and Foster and Hart (Foster, D. P., S. Hart. 2009. An operational measure of riskiness. J. Political Econom. 117(5) 785–814). The paper introduces the generalized options’ impli...
