    Do Real Exchange Rate Changes have Symmetric or Asymmetric Effects on Trade Balance in Nigeria? Evidence from Non-Linear ARDL Model
    (2019) Onatunji, Olufemi
    This paper investigates the asymmetric impact of real exchange changes on trade balance in Nigeria using quarterly data over the period 1999Q1-2017Q4. A non-linear Autoregressive Distributed Lag (NARDL) proposed by Shin et al (2014) is employed for this study. The findings shows that real exchange change have asymmetric impact on Nigeria’s trade balance in both time horizons. Specifically, the positive real exchange rate is highly sensitive to trade balance than the negative real exchange rate. These findings therefore suggest that using discretionary monetary policy to offset Nigeria’s trade deficit due to large differential between import and export is not sufficient enough. Thus, policy makers should adopt policy-mix to manage the current economic climate of the country such as imposition of quotas on certain imported goods, high tariff rate on imported goods, provision of credit facilities and higher tax rate that reduce disposable income of consumer.

    Exchange Rate Volatility and Domestic Investment: Evidence from Twelve ECOWAS Countries
    (African Journal of Economic Review, 2020) Onatunji, Olufemi
    This paper examines the dynamic relationship between exchange rate volatility and domestic investment for twelve ECOWAS countries over the period 1986-2017. We employed the ARDL bound testing approach for co-integration and error correction modeling techniques by incorporating real GDP, real interest rate, real exchange rate, and exchange rate volatility as essential drivers of domestic investment. The results of the ARDL Bound test confirm the existence of long-run relationship among the variables in the selected countries. Furthermore, the findings show that exchange rate volatility is negative and statistically significant only in the case of Nigeria, Sierra Leone, Guinea, Gambia, Cote d’lvoire, Togo, and Liberia but insignificant in Cape Verde, and Senegal. However, contrary to many theoretical predictions and hypotheses, exchange rate volatility is found to be positive but insignificant in Ghana, Benin, and Burkina Faso.

    Exchange Rate Volatility and Foreign Direct Investment in Selected West African Countries
    (The International Journal of Business and Finance Research, 2021) Onatunji, Olufemi
    This paper empirically investigates the exchange rate volatility-FDI nexus in selected Economic Community of West African Sates (ECOWAS) countries using time series data from 1986-2017. Using Autoregressive Distributed Lag (ARDL) model and Toda-Yamamoto (1995) causality techniques, the effects of exchange rate volatility on FDI and causality relationship between the two are examined. The empirical results show that the estimated coefficient of nominal exchange rate volatility is negative in all the selected countries but significant only in Ghana, Sierra Leone, and Nigeria. Conversely, the effect of real exchange rate volatility is negatively significant as expected, in Nigeria, Togo, Sierra Leone, and Cote d’lvore. However, the effect is positive but statistically insignificant in Ghana and Gambia. Furthermore, the causality test results show unidirectional causality from exchange rate volatility to FDI in all selected countries except in Ghana when the nominal exchange rate is employed. On the other hand, when real exchange rate volatility is employed, there is evidence of bidirectional causality between the two variables only in Nigeria and Sierra Leone.
