    An MCDA composite index of bank stability using CAMELS ratios and shannon entropy
    (Springer Science+Business Media, LLC, 2024-05-09) Boubaker S; Ngo T; Samitas A; Tripe D
    This study uses the multi-criteria decision-analysis (MCDA) approach to construct a composite performance index (CPI) directly from the CAMELS financial ratios. The CPI has several promising characteristics, such as (i) being an absolute measure of performance that allows for adding or removing data without affecting the existing scores; (ii) employing CAMELS ratios directly in its calculation without the need for normalization or imputation of positive values; (iii) employing the dynamic weighting system of data envelopment analysis (DEA); (iv) providing more robust insights on the Vietnamese banking system under the Shannon entropy approach; and (v) can be an alternative measure of bank stability, compared to the CAMELS ratings and z-scores. Based on a rich dataset of 45 Vietnamese banks spanning from 2002 to 2020, our findings suggest that the proposed CPI could offer an overall view consistent with other approaches for measuring banking sector performance and stability and identifying specific strengths and weaknesses of banks.

    Estimating the productivity of US agriculture: The Fisher total factor productivity index for time series data with unknown prices
    (John Wiley and Sons Australia, Ltd on behalf of Australasian Agricultural and Resource Economics Society Inc., 2024-05-10) Ngo T; Tripe D; Nguyen DK
    In this paper, we propose a straightforward way to estimate the Fisher ideal total factor productivity (TFP) index (FI) in cases where price information is unavailable, using ‘shadow prices’ derived from data envelopment analysis (DEA). A Monte Carlo experiment shows that the shadow price Fisher ideal TFP index (SPFI) can effectively estimate the ‘true’ FI with relatively small (and stable) errors. The empirical application to the US agriculture sector (1948–2017) further suggests that the SPFI is a (superior) alternative to the traditional Malmquist DEA, especially in dealing with unbalanced panel or time series data when price data are unknown.

    Healthcare expenditure and bank deposits
    (Elsevier, 2023-10-01) Srivastava N; Tripe D; Yuen MK
    This paper investigates the effects of healthcare expenditure on bank deposits in a cross- country analysis. We use government healthcare expenditure, and government and compulsory contributions to the healthcare system as a proxy for healthcare development. The results show a positive relationship between healthcare expenditure and bank deposits. This result is stronger in high income countries and those with a high level of healthcare infrastructure. The results are robust with various specifications tests, including in the COVID-19 pandemic period.

    Operational Efficiency of Bank Loans and Deposits: A Case Study of Vietnamese Banking System
    (MDPI (Basel, Switzerland), 2018-03) Nguyen T; Tripe D; Ngo T
    This paper examines whether there is a causal relationship between bank loans and deposits in the Vietnamese banking system and the efficiency of the use of loans and deposits by the Vietnamese banks. In a country such as Vietnam, where inter-bank money markets are relatively underdeveloped, one would expect a reasonably strong relationship between deposits and loans. A pooled cross-sectional sample of financial ratios is collected from annual reports of 44 Vietnamese banks covering the period 2008–2015. The explanatory power of instrumental variables in relation to the endogenous variables is tested. A deterministic frontier model based on corrected ordinary least squares, estimated by three-stage least squares on a simultaneous equations model, is employed to derive the frontiers for the sampled banks as well as to estimate the causality between bank loans and deposits. Our findings suggest that, in an underdeveloped banking system such as Vietnam, bank deposits have a positive and significant impact on bank loans, but the reverse relationship is not significant. It is further suggested that in deposit-taking and loan-creating activities, Vietnamese banks performed moderately well over the period examined; however, in the near future, they should start to focus more on deposit-taking activities.
