The study employs [1]Exponential Generalized Autoregressive Conditionally Heteroscedastic (EGARCH) model for empirical modeling. The results suggest the presence of own transmission of returns in the banking sector. Further, they yield evidence of own transmission, high persistence, and asymmetric response of volatility in banking stock returns. Additionally, there is evidence of cross transmission of volatility from exchange rates to banking sector returns. The findings have several policy implications for investors, bank managers, and regulators. 2021-01-01T00:00:00Z https://repository.kcau.ac.ke/handle/123456789/1275 Day of The Week Anomaly and Stock Returns Volatility at Nairobi Securities Exchange Onuko, Esther A; Ondabu, Ibrahim T This study sought to investigate the effect of the day of the week anomaly on the stock market returns volatility on the performance of Nairobi Securities Exchange. The study sampled NSE - 20 share index closing prices from September 2000 to December 2019. Data was obtained from the Nairobi Securities Exchange database. Stata version 12 software was used and descriptive statistics to analyse the data using the EGARCH (1, 1) model. The mean analysis results showed the presence of the day of the week effect on the stock market returns of the NSE 20 Share Index at the Nairobi Securities Exchange. This implies that Nairobi Security Exchange performance still contravenes the Efficient Market Hypothesis Theory since investors can use the day of the week anomalies to make abnormal return. The variance analysis showed a positive asymmetric term, implying that positive shocks have greater impact on volatility more than negative shocks of the same magnitude. Positive information in the stock market generates less variance or volatility in the market since positive return translates to high equity prices. This implies that volatility tends to decrease when the stock market returns at the NSE increases than when the stock market decreases with the same amount. 2021-01-01T00:00:00Z https://repository.kcau.ac.ke/handle/123456789/1274 The Effect of Mobile Banking Accounts and Deposits on Operational Efficiency of Commercial Banks in Kenya Orina, Charles O; Ochogo, Fred O This study's main objective was to examine the mobile banking's effect on commercial banks' operational efficiency. The study looked at mobile banking accounts and mobile banking deposits concerning commercial banks' operational efficiency in Kenya. The research was led by the unified theory of acceptance and use of technology model (UTAUT) and Technology acceptance model (TAM). A descriptive research design was used, targeting all the 41 commercial banks. The research adopted a census survey while utilizing secondary data from Central Bank of Kenya and the commercial banks' annual financial reports in Kenya. Data on the number of bank deposits mobilized as savings and the number of registered bank accounts. The study period is from 2010-2018. STATA software was used in data analysis, descriptive and statistical inferential. The independent variables were measured against the dependent variable to examine if they affected commercial banks' operational efficiency. Multiple regression equations estimated the relationship between the variables. Hausman Test was used to specify the adoption of Random effect or Fixed effect models in panel data. The Hausman tested and fixed effect model was selected. The diagnostic tests covering heteroscedasticity, autocorrelation, multicollinearity, and normality tests were also conducted. The findings were presented using graphs and tables. The results were as follows: mobile bank accounts (β=0.0365, p>0.05), and mobile deposits (β=0.015, p>0.05). The study concluded that mobile accounts and mobile deposit had no significant effect on commercial banks' operational efficiency in Kenya. The study recommended that commercial banks invest more in mobile deposits since it had a positive relationship with commercial banks' operational efficiency in Kenya. The study results would enhance the adoption of more efficient financial innovation products and services in the banking industry that would enhance the overall commercial banks operational efficiency. 2021-01-01T00:00:00Z https://repository.kcau.ac.ke/handle/123456789/1273 Impact of International Trade and Foreign Direct Investment on Economic Growth: The Nigerian Perspective Rabiu, Ibrahim D; Adaramola, Anthony O The issues on the international trade and economic growth are of interest not only to policy makers.
