Data Envelopment Analysis in Banking Efficiency
Research Guide
What is Data Envelopment Analysis in Banking Efficiency?
Data Envelopment Analysis (DEA) in Banking Efficiency applies nonparametric frontier techniques to measure technical, allocative, and scale efficiency of banks using multiple inputs and outputs.
DEA models rank Indian banks by efficiency during post-reform periods like 1992-2002 (Das and Ghosh, 2005, 332 citations) and 1997-2005 (Sahoo et al., 2007, 47 citations). Studies incorporate Malmquist indices for productivity changes and bad outputs like NPAs (Dar et al., 2021, 41 citations). Over 20 papers from the list analyze public vs private banks in emerging economies.
Why It Matters
DEA benchmarks enable regulators to identify inefficient banks for policy interventions, as shown in post-deregulation analysis (Das and Ghosh, 2005). Bank managers use efficiency scores for resource allocation, with rural bank restructuring impacts quantified (Khankhoje and Sathye, 2009). Recent applications link NPAs to efficiency gaps, informing NPA management strategies (Arora et al., 2018). Demonetization effects on CAMELS-adjusted efficiency highlight crisis response tools (Akhtar et al., 2022).
Key Research Challenges
Handling Bad Outputs in DEA
Incorporating undesirable outputs like NPAs distorts frontier estimation in banking DEA (Dar et al., 2021). Directional distance functions address this but require robust panel data adjustments. Meta-frontier models separate technology gaps across bank groups (Arora et al., 2018).
Dynamic Productivity Measurement
Malmquist indices capture intertemporal changes but assume constant returns, biasing scale efficiency in liberalizing markets (Sahoo et al., 2007). Window DEA handles time-varying efficiency yet increases model complexity (Akhtar et al., 2021). Post-reform volatility challenges baseline selection (Das et al., 2004).
Public vs Private Bank Comparability
Ownership differences create input-output heterogeneity, invalidating unified frontiers (Das et al., 2004). Meta-frontier analysis bridges gaps but demands extensive covariates (Narwal and Pathneja, 2015). Rural banks require separate models due to scale disparities (Khankhoje and Sathye, 2009).
