Determinants of Hydrogen Bond Financing Costs: Gender Balanced Boards & Bond Maturity Type Risk
(Faculty of Commerce and Management Studies University of Kelaniya., 2024-11-01) Duppati, G.
This study examines whether board female representation and bond maturity type risk individually or jointly affect the issuing firms’ hydrogen bonds financing costs. It predicts that corporations with higher female representation on their boards have lower financing costs than issuing organizations with lower female representation. This paper addresses its research issues by examining a sample of 212 corporate and government institutions across 36 countries engaged in the issuing of Hydrogen green bonds, namely callable bonds or maturity bonds. The data is obtained from the Bloomberg database. This study addresses the research concerns mentioned using a variety of statistical estimating techniques, including regression techniques (OLS and Quantile) and propensity score matching tests. The theories considered in the study include masculinity theory, agency theory, and the study's findings. The study results confirm that female representation is a very important determinant of the hydrogen bond financing costs and are robust to testing with different samples, specifications, and explanations. Despite a significant negative relationship between female board representation and financing costs, firms in the lower segment of the bond coupon rate distribution experience a decrease in bond coupon rates with increased female board representation, as compared to the 50th, 75th, and overall average distributions. This suggests that gender diversity may have differential effects depending on the firm's bond financing conditions.
Factors Affecting the Adoption and Use of Mobile Money in Africa
(9th International Conference on Business and Information (ICBI-2018), Department of Management Studies and Toc H Institute of Science and Technology, India, Faculty of Commerce and Management Studies, University of Kelaniya, Sri Lanka, 2018) Alhassan, A.; Li, L.,; Reddy, K.; Duppati, G.
This research provides preliminary results on context based factors that determines the adoption and use of mobile money (MM) in Africa. Using data from several sources, including Research ICT Africa, International Telecommunication Union and the World Bank, the hypothesized research model tested the context based constructs such as the availability of electricity, enabling regulation and rural dwellings with the technology acceptance model (TAM) to determine how these constructs affect peoples’ intentions and attitudes towards the continuous adoption and use of MM. Exploring these constructs using the structural equation modelling (SEM) technique, the empirical results suggest that the perceived availability of electricity is an important factor for the mobile phone functionality to enable adoption and use of MM. Perceived enabling regulation also show a correlation with individuals’ intention to adopt and use MM. However, perceived rural dwelling is found to negatively correlate with individuals’ attitudes and intentions to adopt and use MM because of the inadequate or lack of mobile network and national grid in rural areas. The policy implication is that African governments’ public-private partnerships (PPPs) can assist with the construction of the relevant infrastructure for shared growth
Understanding GCC Banks: Credit risk, Interest Charges, and Operating efficiency
(Faculty of Commerce and Management Studies University of Kelaniya., 2024-11-01) Duppati, G.; Maamari, B.E.
This study empirically examines two research questions: First, whether the Credit Risk increases the operating efficiency of banks? And second, whether Interest Charges Influences the relationship between Credit Risk and Operating Efficiency? This study uses the secondary data and it is drawn from EIKON DataStream for the period 2005 to 2022. The sample size of the study includes 50 banks of the GCC region, covering eight states, which includes: Abu Dhabi, Dubai, Saudi Arabia, Sharjah, Kuwait, Oman, Qatar and UAE. For addressing the research questions raised in this study, we employ different regression techniques that include the fixed effects (FE) model and System dynamic panel-data estimation test to ensure robustness of the results. Our results show that high interest rates benefit the 25th and 75th percentiles, but the firm's ability to adapt, innovate, and restructure in response to the changing financial environment will determine how much they benefit lower efficiency quantiles. Banks that overcome these challenges may become more competitive, efficient, and streamlined. While higher interest rates increase financing costs and financial constraints for lower- efficiency banks, they can also spur good transformation.
