The Effect of Financial Innovation and Bank Competition on Firm Value
Oluwaseyi Ebenezer OLALERE,Marniati S.E.M. KES,Md. Aminul ISLAM,Shafiqur RAHMAN 한국유통과학회 2021 The Journal of Asian Finance, Economics and Busine Vol.8 No.6
This study examines the effect of financial innovation (FI) and bank competition on firm value. FI is the act of creating new financial instruments as well as new financial technologies, institutions, and markets. The study used the sys-GMM estimation technique based on data extracted from 26 commercial banks in Nigeria and Malaysia over the period 2009 to 2019, totaling 286 observations. Given the results of the study, FI has a significant negative effect on firm value in Nigeria, and bank competition has a significant negative effect on firm value in Nigeria. By contrast, FI has a significant positive effect on firm value in Malaysia, and bank competition has a significant positive effect on firm value in Malaysia. The return on asset (ROA), bank size, GDP growth, and the inflation rate are significantly related to firm value. The interactive effect (FI * COMP) has a significant positive relationship with firm value in Nigeria and Malaysia. The empirical study confirms the notion that FI is a real driver of economic progress, competitiveness, and economic development. According to the study, policymakers should address the weaknesses exposed by the financial crisis, which contributed to the introduction of various current financial regulatory frameworks to capture the risks posed by the FI process.

The present work focuses on the development and investigation of new composite materials based on regenerated nanocellulose, titanium oxide (TiO2) and zinc oxide (ZnO) with potentials for drug delivery applications. The new composite was developed using dispersion method. The physicochemical properties of the composites were extensively evaluated using scanning electron microscopy (SEM), X-ray diffraction (XRD), particle size analyzer and Fourier transform infrared spectroscopy (FTIR). The presence of O-H, C-H, C-O-C, Ti-O, Zn-O stretch and bend was confirmed using the FTIR, while the SEM revealed the TiO2 and ZnO immobilized on the surface of stiff and rod-like strands of regenerated nanocellulose. The XRD showed characteristic peaks at 2θ of 16.6o, 22.7o, 34.4o for nanocellulose, 17.5o, 24.5o, 32o for ZnO and 25.4o, 38o, 48.3o, 53.8o for TiO2. As the amount of the metal oxides in the composite increased, notable increase in physicochemical properties and morphology for drug delivery purpose was observed. The cumulative drug release profiles of the regenerated nanocellulose composites on tramadol hydrochloride were subjected to zero order, first-order, Higuchi and Korsmeyer-Peppas plots, and fitted most for Korsmeyer-Peppas with R2 and n value from 0.9831 to 0.9941 and 0.4188 to 0.9704, respectively.

Background :Fetal hemoglobin (HbF) levels in different hemoglobin variants in Osogbo, Nigeria, were estimated using two principal methods of estimation using existing information for HbF concentration and distribution of various hemoglobin variants in the area, as well as diagnosed cases of thalassemia. Two hundred and sixty samples collected from HbSS, HbSC, HbAA, HbAS, and HbAC subjects were analyzed. HbF level and hemoglobin type were determined in this study. Methods :The hemoglobin type was determined using cellulose acetate electrophoresis at an alkaline pH, and HbF was determined by the acid elution and alkaline denaturation methods. Results :The mean±SD of HbF in the respective hemoglobin variants was as follows: HbSS, 2.09±1.94%; HbSC, 0.85±0.54%; HbAA, 0.69±0.46%; HbAS, 0.52±0.31%; and HbAC, 0.57±0.26%. The mean HbF level across the hemoglobin variants was statistically significant (P<0.05). Investigating the sex distribution of the HbF level in the studied population revealed a slightly higher mean HbF level in females than in their male counterparts. Conclusion :Within the study population, the HbF level was found to be highest in HbSS and lowest in HbAS. The two methods of estimating HbF are equally reliable, since there was no significant difference between the results obtained from the two methods.
