In 2015, economic growth in Sub-Saharan Africa (SSA) slowed to 3.4 percent from 4.6 percent the previous year. The economic slowdown in the region was the result of an interplay of several external and domestic factors such as lower commodity prices, slowdown in the economies of major trading partners, tightening borrowing conditions, political instability and conflict, electricity shortages and other infrastructure deficiencies (World Bank, 2016). This sluggish growth trends is in contrast to the impressive growth recorded in the region, over the past decade.

This study examines the potential of regional trade in facilitating the achievement of inclusive development in the West African region. It employs descriptive analysis to examine the nature, composition and dimension of ECOWAS trade within the group and with the rest of the world, vis--vis three other Regional Economic Communities (RECs) in sub-Saharan Africa (SSA). From the preliminary study, it can be observed that the growth rate of West African economies is increasing, but the rising economic growth does not translate to improvement in inclusive development, as there was no significant reduction in poverty levels in the region. Further evidence reveals that extra-regional trade of the region is increasing at a very high rate, and also at a disproportionate rate with intra-regional trade, compared with SADC. This indicates the existence of opportunity to boost regional trade for inclusive development through conversion of part of the extra-regional trade into regional trade.

This study examines the hedging effectiveness of portfolio investment diversification between developed and developing economies; with focus on the Nigerian stock asset vis--vis the stock assets of the United States (US) and United Kingdom (UK). Its main contribution is in the analysis of optimal portfolio diversification using optimal portfolio weight (OPW) and optimal hedging ratio (OHR). Empirical findings show that the OPW and OHR are low, which indicates impressive potential gains from combining Nigerian stock assets in an investment portfolio with US and UK stock assets. In addition, exchange rate volatility is found to pose stern limitation on the potential benefits of this portfolio diversification arrangement. It is therefore recommended that the monetary authority in Nigeria should pursue policies towards reducing exchange rate volatility to the barest minimum. This will possibly attract more investors from developed economies who might be willing to combine Nigerian stock in their investment portfolio to minimize portfolio risk.

This study investigates the effects of merchandise trade and investment flows on the transmission of business cycles between members of ECOWAS and the major trading partnersbetween 1985 and 2014. Total trade and FDI significantly influence the transmission of business cycles with elasticities of 1.1% and 0.7%, respectively in the long run. There are little variations across the major trading partners and other measures of trade flows. Intra-industry trade flows with all partners, EU and USA influences the cross-country business cycles with elasticities of 1.0%, 0.5% and 1.8%, respectively. 

There is a link between primary commodity export prices and economic performance. Many African economies are primary commodities export biased, often in few primary commodities. Previous studies focus on the impact of commodity prices on growth in Africa with little attention paid to different primary commodities and level of diversification in primary commodities export. This study, investigates the effect of primary commodity prices on the long-run growth of 24 primary commodities-based African economies; by commodity types and level of diversification in primary commodities exports.
