A critical review of the Nigerian banking system over the years shows that one of the problems confronting the sector has been that of poor corporate governance. In an attempt to investigate the linkage between corporate governance and financial performance of banks, this study contributed to the existing literature by assessing the effect of size of boards on the performance of banking sector in a developing economy like Nigeria. This study made use of a range of data drawn from the Nigerian Stock Exchange fact book (2008), which contains information on board size and the performance proxies. Regressing performance on board size, it was observed that banks with board size below 13 are more viable than those with board size above 13. The study further observed that banks with larger boards recorded profits lower than those with smaller boards. Therefore, this study concludes that there is a significant negative relationship between board size and bank financial performance with a t-value of -1.977 and a p-value of 0.053. This is because, increase in board size occurs with increase in agency problems (such as director free-riding) within the board and the board becomes less effective. However, the paper recommends a smaller board size for better financial performance and to reduce the problem of free-rider of banks in Nigeria.

The quality of financial report and the extent to which investors rely on them to forecast future earnings is dependent on the accounting standards employed. The impact of IFRS adoption on earnings predictability of listed banks in Nigeria was examined in this study considering a sample of 11 listed banks in Nigeria. Categorically, data were obtained from the financial statement 2013 to 2014 (post-adoption period) and 2010 to 2011 (pre-adoption period). The data obtained were analyzed using regression on the Statistical Package for Social Sciences (SPSS). The study found a decrease in the ability of current earnings to predict future earnings after the adoption period. Thus, IFRS adoption has a negative impact on earnings predictability. The study further suggested that regulatory bodies of the banking sector should enforce strict adherence to IFRS procedures and principles, as well as put in place measures that will improve investors' protection.

We examine the effect of social media advertising on the operating, financing and investing level of cash flow based on listed banks in emerging economies in Africa. We employ control variables such as board size and financial leverage to control other factors not captured in our model. Results obtained reveal that social media costs aid all levels of cash flow in Ghana and South-Africa. Social media costs in Botswana have a significant impact with operating and financing cash flow and an insignificant effect with investing cash flow. The results obtained from Kenya revealed a significant relationship between the independent variable and the financing and investing cash flow while an insignificant relationship was statistically obtained when social media cost was regressed against the operating level of cash flow. The Tanzanian results reveal a significant impact with the financing and investing level of cash flow but an insignificant value was obtained from the operating level of cash flow. The Nigerian results yielded an insignificant value, from the operating and financing level of cash flow, while investing cash flow generated a significant relationship.
