Despite significant technological innovation in retail banking services delivery, the number of Nigerian bank branches has grown steadily over time. This paper assesses the implications of these developments by examining the contribution of the branches to banks performance. The study uses the whole banks in Nigeria during the period 1981 and 2013 using a pooled data analysis on ordinary least square(OLS).The variables used include the total number of banks branches in rural and urban area and those domiciled abroad regarded as foreign branches. It also considered the total number of banks at each period and year of study while the growth in Total Asset is proxied as the dependent variable. Our findings showed that there is a positive relationship between the growths of the branches in the rural, urban and foreign centres which implies that there is need to open more branches if the banks wants the Asset to grow. We find no systematic relationship between number of banks and Asset growth perhaps because banking organizations optimize the size of their branch network operations as part of an overall strategy involving both branch-based and non-branch-based activities. The study suggested that branching activities should be a major work and decision of the banks so as to bring more customers to the bank who will now use the various electronic platforms for service installed by the banks.
This paper analyses the structure, conduct, and performance of commercial banks in Ghana. The empirical investigation uses two different measures of concentration to represent market structure and a market share variable to capture the effect of Market conduct on bank performance, and two accounting measures: return data on Return on Assets (ROA), return on equity (ROE) to represent banks’ performance. Annual time series data ROA, ROE and other ratios were collected from nineteen commercial banks over the period 2007 -2012. The results indicated that market concentration and market share significantly determines profitability in Ghana, signifying the strong acceptance of the SCP hypothesis. Consequently, the research suggests the need for improvement in bank capitalization, bank size, service product innovation and effective liquidity management for the Ghanaian banking industry
