Our empirical evidence, based on data from 96 countries, indicate a significant non-linearity between remittances, ICT and pension income coverage. First, we find a convex relation between remittances and pension income coverage, indicating that increases in remittance, initially decreases pension income coverage, but as remittance increases beyond a certain point, so too does pension income coverage. This inflection point, where the effect of remittances turns from negative to positive, is estimated to be around 3.09% of GDP. Second, we document a concave relationship between ICT (i.e. mobile subscription and internet penetration) and pension income coverage. An increase in ICT results in increased pension income coverage. However, when ICT reaches a certain point, any further increase is associated with lower pension income coverage. The estimated optimal point is found to be around 140.14 subscriptions (per 100 people) for mobile phone and 27.93 (per 100 people) for internet penetration, respectively. Other implications are discussed.}, keywords = {Mobile phones, Pension, remittances}, pubstate = {published}, tppubtype = {unpublished} } This study examines the impact of remittances and information and communication technology (ICT) on pension at the country level.

Using 25 policy variables, we investigate determinants of mobile phone penetration in 49 Sub-Saharan African countries with data for the period 2000–2012. The empirical evidence is based on contemporary and non-contemporary OLS, Fixed Effects, System GMM, and Quantile Regression techniques. The determinants are classified into six policy categories. They are: (i) macroeconomic, (ii) business/bank, (iii) market-related, (iv) knowledge economy, (v) external flows, and (vi) human development. Results are presented in terms of threshold and non-threshold effects. The former has three main implications. First, there are increasing positive benefits in regulation quality, human development, foreign investment, education, urban population density, and Internet penetration. Second, there is evidence of decreasing positive effects from patent applications. Third, increasing damaging influences are established for foreign aid and return on equity.
