Knowledge Economy and Financial Sector Competition in African Countries

The goal of this paper is to assess how knowledge economy (KE) plays out in financial sector competition. It suggests a practicable way to disentangle the effects of different components of KE on various financial sectors. The variables identified under the World Bank’s four knowledge economy index (KEI) are employed. An endogeneity robust panel instrumental variable fixed-effects estimation strategy is employed on data from 53 African countries for the period 1996-2010. The following findings are established. First, education and innovation in terms of scientific and technical publications broadly bear an inverse nexus with financial development. Second, the incidence of information and communication technologies is positive on all financial sectors but increases the non-formal sectors to the detriment of the formal sector. Third, economic incentives have positive implications for all sectors though the formal financial sector benefits most. Fourth, institutional regime is positive (negative) for the semi-formal (informal) financial sector. The findings contribute at the same time to the macroeconomic literature on measuring financial development and respond to the growing fields of informal sector importance, microfinance and mobile banking by means of KE promotion. Policy implications and future research directions are discussed

Genetic gains in early maturing maize hybrids developed by the International Maize and Wheat Improvement Center in Southern Africa during 2000–2018

Genetic gain estimation in a breeding program provides an opportunity to monitor breeding efficiency and genetic progress over a specific period. The present study was conducted to (i) assess the genetic gains in grain yield of the early maturing maize hybrids developed by the International Maize and Wheat Improvement Center (CIMMYT) Southern African breeding program during the period 2000–2018 and (ii) identify key agronomic traits contributing to the yield gains under various management conditions. Seventy-two early maturing hybrids developed by CIMMYT and three commercial checks were assessed under stress and non-stress conditions across 68 environments in seven eastern and southern African countries through the regional on-station trials. Genetic gain was estimated as the slope of the regression of grain yield and other traits against the year of first testing of the hybrid in the regional trial. The results showed highly significant (p< 0.01) annual grain yield gains of 118, 63, 46, and 61 kg ha−1 year−1 under optimum, low N, managed drought, and random stress conditions, respectively. The gains in grain yield realized in this study under both stress and non-stress conditions were associated with improvements in certain agronomic traits and resistance to major maize diseases. The findings of this study clearly demonstrate the significant progress made in developing productive and multiple stress-tolerant maize hybrids together with other desirable agronomic attributes in CIMMYT’s hybrid breeding program
