“…In addition, the data set used depicts a scenario, in which inputs are significantly and positively correlated with outputs, thereby fulfilling the “isotonicity” conjecture. This scenario is consistent with the common practice in prior studies (for examples, Nourani et al , 2018b; Nourani et al , 2020). Second, the current research uses the truncated regression technique with a bootstrapping approach (Barros et al , 2010).…”

PurposeThe purpose of this study is twofold. First, this research estimates banks' efficiencies from the perspectives of resource utilization and investment after incorporating risk measures as an exogenous input in the investment-efficiency stage. Second, the current study examines the relationship between intellectual capital (IC) and banks' efficiencies.Design/methodology/approachFirst, this study uses a dynamic network data envelopment analysis approach in investigating the efficiencies of 24 Taiwanese banks in 2007–2018 from two perspectives. Second, this research utilizes various regression techniques, namely, ordinary least squares (OLS), robust least squares and truncated regression, to gauge the impact of IC on banks' efficiencies. Typically, IC is determined based on a monetary value-based measure and value-added intellectual coefficient (VAICTM).FindingsResource-utilization (investment) efficiencies were observed as 0.941 (0.964), thereby contributing to the mean overall efficiency of the sample banks at 0.952. However, the related efficiency changes decline over the sample period, thereby suggesting that the average banks' efficiencies hardly increase. Regression analyses show a significantly positive relationship between IC and banks' overall resource-utilization and investment efficiencies.Research limitations/implicationsOverall, this study suggests that researchers should consider risks when estimating banks' efficiencies owing to their connection to banks' investment performance. From banks' dynamic two-stage efficiencies, this study demonstrated that investments in IC will bring improved future economic benefits.Originality/valueDifferent from prior studies, this study improves banks' efficiency evaluation models by incorporating risk measures and assuming weighted periods for the 2007–2008 global financial crisis. Moreover, the use of monetary value-based measure of IC provides consistent results as the commonly-used VAICTM does.

“…The dynamic DEA model we consider also accounts for any intertemporal effects of desirable and undesirable carry‐overs between years, including risk in the form of NPLs, and is particularly suited to study efficiency in the banking sector. This represents an improvement over aggregated indices, such as the Malmquist Productivity Index and the Luenberger Productivity Indicator, which do not account for these aspects (Wanke et al., 2015; Wijesiri, 2016; Wu et al., 2016; Nourani et al., 2020). Additionally, second‐stage Tobit and Beta regressions are based on stochastic nonlinear programming and bootstrapping techniques, which limits problems of lack of discriminatory power of the scores computed in the first stage (Wanke et al.…”

This paper investigates the relationship between bank ownership and efficiency before and after the 2008–2009 Global Financial Crisis. Using a sample of 58 Indian commercial banks from 2005 to 2017, we examine the interconnection between these factors in a dynamic data envelopment analysis (DEA) framework. We use an innovative modeling strategy based on a two‐stage dynamic DEA framework. The first stage employs the Dynamic Slack‐Based Measure model to measure bank efficiency, explicitly considering the effects of desirable and undesirable carry‐overs between consecutive periods. In a second stage, we perform a regression of the efficiency scores on bank ownership types and several other contextual factors, while also accounting for the presence of endogenous relationships between the variables involved. Our results show that foreign banks outperform their domestic competitors, with bank size and profitability being the main drivers. We also find that while foreign and state‐owned banks were more efficient than their rivals during the Global Financial Crisis, private banks recovered quickly, reaching the efficiency standards of state‐owned banks by 2017. The latter faced a prolonged decrease in efficiency, gradually losing their initial advantage over their private domestic counterparts. Our results are robust to alternative regression specifications, especially those aimed at addressing potential endogeneity issues. The applied methodology and the findings of our research should be of interest to scholars, bank managers, and policymakers. The latter, in particular, should be concerned about the medium‐term effects of reforms that unevenly affect banks with different ownership structures, especially in terms of bank resilience to aggregate shocks.
