This paper seeks to evaluate efficiency and competition dynamics of the banking sector in Kenya for the period 2001–2017 using bank‐level data for 37 commercial banks. We apply non‐parametric data envelopment analysis to analyze measures of various aspects of efficiency in the banking sector. We also adopt Panzar–Rosse, H‐statistics to assess the level of competition in the banking sector. To examine the effect of efficiency on competition, panel estimators are applied. The study findings indicate that efficiency was on an upward trend and averaged 69%. The banking sector is characterized by monopolistic competition as shown by an H‐statistic of.59. Managerial ability measured by data envelopment analysis efficiency score was found to be an important factor in promoting competition for the Kenyan banking sector. The study shows that there is room for Kenyan banks to improve their efficiency by optimizing the scale of operations and continuing to adopt technology. This paper recommends policy makers to continue adopting policies that promote greater banking sector efficiency and competition. [ABSTRACT FROM AUTHOR]

This paper examines the strategic fit of mergers and acquisitions (M&A) in Mozambican banks, using a two-stage data envelopment analysis (DEA) approach to compute the impact of contextual variables on efficiency scores and returns to scale of the resulting virtual merged banks. In an 'M&A DEA' model, different pairs of bidder and target companies are considered. In the first stage an M&A DEA model is used. Simplex regression is adopted in the second stage. The results reveal that ownership (public or foreign) impacts virtual efficiency levels. However, the findings also show that care must be exercised with M&A because the resultant banking organization could be oversized when foreign ownership is predominant, especially when public ownership is low. Given the relative sizes of the markets in terms of productive resources, M&A involving Mozambican banks can easily lead to decreasing returns to scale. Thus, a greater emphasis should be given to merging purely public banks with foreign ones and vice versa. [ABSTRACT FROM AUTHOR]

We analyse the evolution of competition and efficiency of the banking sector in South Africa using firm-level data for the period 1999-2008. We adopt a three-step estimation approach. First, we measure efficiency using the data envelopment analysis (DEA) methodology. Second, we use the Panzar-Rosse approach to derive the H-statistic for competitive conditions in banking. In the third stage, we take into account the role of managerial ability in competition by re-estimating the Panzar-Rosse model, with the DEA efficiency scores as an explanatory variable. Overall, the results show that although average efficiency was trending upwards over the period, the number of efficient banks was falling. Also, it is found that for the period 1999-2008, the structure of the South African banking industry was characterized by monopolistic competition. This result may reflect domination by five large banks, which together account for over 85 per cent of total banking assets. [ABSTRACT FROM AUTHOR]

This study estimates technical efficiency and total factor productivity change in the Nigerian banking sector for the period 2005–14, which encapsulates the post‐consolidation era and subsequent regime of banking reforms aimed at stabilizing the sector from the effects of financial crisis. The study applies both non‐parametric Data Envelopment Analysis (DEA) and parametric Stochastic Frontier Approach (SFA), using the Malmquist Productivity Index, and error component production function respectively, to ascertain if any significant variation in efficiency exists on a sample of 12 banks covering over 80 percent of total bank assets in Nigeria. The theoretical intermediation approach is applied for selection of input and output variables. The input variables considered are total deposits, total equity and operating expenses including staff costs, and output variables are loans and operating income, which accounts for off‐balance‐sheet items such as non‐interest or fee‐based income. Findings reveal that the mean technical efficiency under SFA and total factor productivity change in DEA decreases as bank output moves toward non‐interest or fee‐based income. Although the magnitude differs, both SFA and DEA follow a similar direction for technical efficiency and total factor productivity change. Study implications suggest that policymakers should be concerned about arbitrariness in bank's ability to earn fee‐based income, which portends high cost of banking services in the long run.

We investigate the interrelationships among bank competition, risk taking and efficiency during banking sector reforms in Nigeria (1993-2008). Our modelling procedure involves three stages: we measure bank productive efficiency, using data envelopment analysis, and the evolution of bank competition, using conjectural variations (CV) methods; then, we use the CV estimates to test whether regulatory reforms influence bank competition; finally we investigate the impact of the reforms on bank behaviour. The evidence suggests that deregulation and prudential re-regulation influence bank risk taking and bank productive efficiency directly (direct impact) and via competition (indirect impact). Further, it is found that as competition increases, excessive risk taking decreases and efficiency increases. Overall, the evidence on Nigeria affirms policies that foster bank competition.
