abstract = {Purpose - This study investigates how bank size affects the role of information asymmetry on financial access in a panel of 162 banks in 39 African countries for the period 2001-2011.

Design/methodology/approach - The empirical evidence is based on instrumental variable Fixed Effects regressions with overlapping and non-overlapping bank size thresholds to control for the QLH (Quiet Life Hypothesis). The QLH postulates that managers of large banks will use their privileges for private gains at the expense of making financial services more accessible to the general public. Financial access is measured with loan price and loan quantity whereas information asymmetry is implicit in the activities of public credit registries and private credit bureaus.

Findings - The findings with non-overlapping thresholds are broadly consistent with those that are conditional on overlapping thresholds. First, public credit registries have a decreasing effect on the price of loans with the magnitude of reduction comparable across all bank size thresholds. Second, both public credit registries and private credit bureaus enhance the quantity of loans. Third, compared with public credit registries, private credit bureaus have a greater influence in increasing financial access because they have a significantly higher favourable effect on the quantity and price of loans Fourth, the QLH is not apparent because large banks are not associated with lower levels of financial access compared to small banks.

Originality/value - Studies of public credit registries and private credit bureaus in Africa are sparse. This is one of the few to assess linkages between bank size, information asymmetry and financial access.},

abstract = {This study assesses the knowledge economy (KE) performance of lagging African countries vis-à-vis their frontier counterparts with regard to the four dimensions of the World Bank’s knowledge economy index (KEI). The empirical exercise is for the period 1996-2010. It consists of first establishing leading nations before suggesting policy initiatives that can be implemented by sampled countries depending on identified gaps that are provided with the sigma convergence estimation approach. The following are established frontier knowledge economy countries. (i) For the most part, North African countries are dominant in education. Tunisia is overwhelmingly dominant in 11 of the 15 years, followed by Libya which is a frontier country in two years while Cape Verde and Egypt lead in a single year each. (ii) With the exception of Morocco that is leading in the year 2009, Seychelles is overwhelmingly dominant in ICT. (iii) South Africa also indomitably leads in terms of innovation. (iv) While Botswana and Mauritius share dominance in institutional regime, economic incentives in terms of private domestic credit are most apparent in Angola (8 years), the Democratic Republic of Congo (3 years) and Tanzania, Sierra Leone and Malawi (each leading in one year).},

abstract = {The study investigates how education, scientific output and the internet complement mobile phone penetration to affect technology commodity exports in Sub-Saharan Africa for the period 2000-2012. The empirical evidence is based on Generalised Method of Moments. The following main findings are established. First, the internet complements the mobile phone to boost technology goods exports. Second, the internet also complements the mobile phone to boost technology service exports. Third, positive marginal effects are apparent in the roles of educational quality and scientific output on technology goods exports and technology service exports respectively while negative marginal impacts are apparent in the roles of scientific output and educational quality on technology goods exports and technology service exports respectively. Practical and theoretical implications are discussed.},

abstract = {Using cross-country differences in the degree of isolation before the advent of technologies in sea and air transportation, we assess the relationship between geographic isolation and financial development across the globe. We find that pre-historic geographical isolation has been beneficial to development because it has contributed to contemporary cross-country differences in financial intermediary development. The relationship is robust to alternative samples, different estimation techniques, outliers and varying conditioning information sets. The established positive relationship between geographic isolation and financial intermediary development does not significantly extend to stock market development.},

abstract = {This study examines how information and communication technology (ICT) complements carbon dioxide (CO2) emissions to influence inclusive human development in forty-four Sub-Saharan African countries for the period 2000-2012. ICT is measured with internet penetration and mobile phone penetration. The empirical evidence is based on Generalised Method of Moments. The findings broadly show that ICT can be employed to dampen the potentially negative effect of environmental pollution on human development. We establish that: (i) ICT complements CO2 emissions from liquid fuel consumption to increase inclusive development; (ii) ICT interacts with CO2 intensity to negatively affect inclusive human development and (iii) the net effect on inclusive human development is positive from the complementarity between mobile phones and CO2 emissions per capita. Conversely, we also establish evidence of net negative effects. Fortunately, the corresponding ICT thresholds at which these net negative effects can be completely dampened are within policy range, notably: 50 (per 100 people) mobile phone penetration for CO2 emissions from liquid fuel consumption and CO2 intensity. Theoretical and policy implications are discussed.},

abstract = {This study examines how increasing ICT penetration in sub-Saharan Africa (SSA) can contribute towards environmental sustainability by decreasing CO2 emissions. The empirical evidence is based the Generalised Method of Moments and forty-four countries for the period 2000-2012. ICT is measured with internet penetration and mobile phone penetration while CO2 emissions per capita and CO2 emissions from liquid fuel consumption are used as proxies for environmental degradation. The following findings are established: First, from the non-interactive regressions, ICT (i.e. mobile phones and the internet) does not significantly affect CO2 emissions. Second, with interactive regressions, increasing ICT has a positive net effect on CO2 emissions per capita while increasing mobile phone penetration alone has a net negative effect on CO2 emissions from liquid fuel consumption. Policy thresholds at which ICT can change the net effects from positive to negative are computed and discussed. These policy thresholds are the minimum levels of ICT required, for the effect of ICT on CO2 emissions to be negative. Other practical implications for policy and theory are discussed.},

abstract = {This study assesses dynamics of openness and finance in Africa by integrating financial development dynamics of depth, activity and size in the assessment of how financial, trade, institutional, political and other openness policies (of second generation structural and institutional reforms) have affected financial development. The empirical evidence is based on Generalized Method of Moments with data from 28 African countries for the period 1996-2010. The following findings are established. (i) While the de jure (KAOPEN) indicator of financial openness improves financial depth, the de facto (FDI) measurement decreases it, with the effect of the latter measure positive on financial size. (ii) Whereas trade openness improves financial depth, its effect on financial activity and size is negative. (iii) Institutional openness has a positive effect on financial dynamics of depth and activity, while its effect on financial size is negative. (iv) Political openness and economic freedom are detrimental to financial depth and activity. Justifications for these nexuses are discussed.},
