Efficiency Measurement of Bank Branches with Undesirable Output Using Non-Radial Models of Data Envelopment Analysis

Today, banks, as intermediaries, seek to attract and allocate resources to obtain greater benefit. Therefore, the bank assessment is considered as an important subject in the banking industry. Data envelopment analysis is an effective technique in evaluating the efficiency of decision-making units. There are factors among banking indices (such as receivables from resource allocation) that are i...

NPA as an Undesirable Output in Indian Commercial Banking: Additive Slack Based Efficiency DEA Model

Nonperforming assets (NPA) reflect the risk factor of the concerned commercial bank. Some of these banks operate at a threshold point where further reduction of NPA is not possible without reducing loans and advances, a desirable output. Pursuing an additive slack based efficiency DEA model the potential rate of reduction of NPA is explored for 50 commercial banks operating on Indian soil.

Efficiency Measurement in Two-Stage Network Structures Considering Undesirable Outputs

Since data envelopment analysis (DEA) introduced in 1970s, it has been widely applied to measure the efficiency of a wide variety of production and operation systems. Recently DEA has been extended to examine the efficiency of decision making units (DMUs) with two-stage network structures or processes, where the outputs from the first stage are intermediate measures that make up the inputs of t...
