Does exchange rate volatility deter trade in Sub-Saharan Africa?

Abstract: This study investigates the effects of exchange rate volatility on trade in 39 selected Sub-Saharan Africa (SSA) countries for the period 1995-2012. Export and import models were estimated using panel data econometric technique. Three measures of volatility are used. These are standard deviation, generalized autoregressive conditional heteroskedasticity and Hodrick-Prescott (HP)-Filter. The results suggest that the effect of exchange rate volatility on trade is dependent of the type of volatility measure used. This reflects the importance of not solely relying on a unique measure of volatility. The results revealed that exchange rate volatility (measured with standard deviation and HP filter) depresses exports, suggesting that SSA exporters are susceptible to reduce their export activities when exchange rates become volatile. However, the fact that the degree of the impact of exchange rate volatility on trade is relatively weak, suggest that should SSA’s policy makers decide to pursue a policy intended to reduce exchange rate volatility in order to boost trade, it might be of little or no value. The results also indicate that exchange rate volatility is associated with a reduction in imports

Technology and persistence in global software piracy

This study examines the persistence of software piracy with internet penetration vis-à-vis of PC users, conditional on Intellectual Property Rights (IPRs) institutions. The empirical evidence is based on a panel of 99 countries for the period 1994-2010 and the Generalised Method of Moments. The main finding is that, compared to internet penetration, PC usage is more responsible for the persistence of global software piracy. Knowing how technology affects the persistence of piracy is important because it enables more targeted policy initiatives. We show that the sensitivity of software piracy to IPRs mechanisms is contingent on the specific technology channels through which the pirated software is consumed

Revisiting the Finance-Inequality Nexus in a Panel of African Countries

The study assesses the role of financial development on income inequality in a panel of 48 African countries for the period 1996 to 2014. Financial development is defined in terms of depth (money supply and liquid liabilities), efficiency (from banking and financial system perspectives), activity (at banking and financial system levels) and stability while, three indicators of inequality are used, namely, the: Gini coefficient, Atkinson index and Palma ratio. The empirical evidence is based on Generalised Method of Moments. When financial sector development indicators are used exclusively as strictly exogenous variables in the identification process, it is broadly established that with the exception of financial stability, access to credit (or financial activity) and intermediation efficiency have favourable income redistributive effects. The findings are robust to the: control for unobserved heterogeneity in terms of time effects and inclusion of time invariant variables as strictly exogenous variables in the identification process. The findings are also robust to the Kuznets hypothesis: a humped shaped nexus between increasing GDP per capita and inequality. Policy implications are discussed

Does Exchange Rate Volatility Deter Trade in Sub-Saharan Africa?

This study investigates the effects of exchange rate volatility on trade in 39 selected SSA countries for the period 1995 to 2012. Export and import models were estimated using panel data econometric technique. Three measures of volatility are used. These are standard deviation, GARCH and HP-Filter. The results suggest that the effect of exchange rate volatility on trade is dependent of the type of volatility measure used. This reflects the importance of not solely relying on a unique measure of volatility. The results revealed that exchange rate volatility (measured with standard deviation and HP filter) depresses exports, suggesting that SSA exporters are susceptible to reduce their export activities when exchange rates become volatile. However, the fact that the degree of the impact of exchange rate volatility on trade is relatively weak, suggest that should SSA's policy makers decide to pursue a policy intended to reduce exchange rate volatility in order to boost trade, it might be of little or no value. The results also indicate that exchange rate volatility is associated with a reduction in imports.

The role of value added across economic sectors in modulating the effects of FDI on TFP and economic growth dynamics

This study investigates: (i) the effect of foreign direct investment (FDI) on total factor productivity (TFP) and economic growth dynamics, and (ii) the relevance of value added from three economic sectors in modulating the established effect of FDI on TFP and economic growth dynamics. The geographical and temporal scopes are respectively 25 Sub-Saharan African countries and the period 1980–2014. The empirical evidence is based on non-interactive and interactive Generalised Method of Moments. The following main findings are established. First, FDI has a positive effect on GDP growth, GDP per capita and welfare real TFP. Second, the effect of FDI is negative on real GDP and TFP, while the impact is insignificant on real TFP growth and welfare TFP. Third, values added to the three economic sectors largely modulate FDI to produce negative net effects on TFP and growth dynamics. Policy implications are discussed with particular emphasis on the need to complement added value across various economic sectors in order to leverage on the benefits of FDI in TFP and economic growth. To the best of knowledge, this is the first study to assess how value added from various economic sectors affect the relevance of FDI on macroeconomic outcomes
