This 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 a generalized method of moments. The following main findings are established. The internet complements the mobile phone to boost technology goods exports and technology service exports. In addition, 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.

The establishment of a currency union is a topical issue in the West African Monetary Zone (WAMZ). The subject of currency union formation needs to be reassessed in light of the recent efforts towards the economic integration of west African countries. This study employs the Markov Switching Model (MSM) to determine whether a currency union in WAMZ is feasible. The study analyzes the regime switching behavior in WAMZ countries’ foreign exchange markets before and after the formation of the union. The contribution of this study is two-fold. First, the study accounts for the success or otherwise of the latest efforts to integrate the fiscal and monetary strategies in the zone. Secondly, the study contributes to the literature on the currency union literature in WAMZ by using Markov Switching Model (MSM) to generate novel results. The results of the study revealed that prior to the WAMZ formation, the real exchange rates of member states were more divergent. In contrast, a growing but marginal, convergence was observed after the formation of the zone amongst four (Nigeria, Sierra Leone, Gambia, and Liberia) of the six countries. The authors conclude that while WAMZ is on course for establishing a currency union, their monetary authorities must work together, particularly with Ghana and Liberia, to synchronize their policy efforts, and policy makers must implement policies to strengthen harmonious trade interactions.
