Migrant Remittances and Naira Price of the Dollar (Published)

This study investigated the possibility that the large amount of diaspora dollar remittance to the Nigeria economy could positively impact the naira price of the dollar (exchange) rate. Our methodology employed the Johansen cointegration test (JCT).The trace statistics result shows the null hypothesis that: there is no cointegration is rejected. Thus the trace test shows, there is at least one co-integrating vector. Furthermore, the output of the Max-Eigen statistics indicates that there is a strong evidence to reject the null hypothesis of no cointegration, implying there is long run relationship among the variables. Though diaspora remittance (logrem) has positive and significant long run effect on the domestic price of the naira (logexch) to the dollar, its coefficient (3.220574) is not sufficiently large when compared with oil price (24.56832) (logoilprice). We therefore conclude that though diaspora remittances influences the domestic naira price of the dollar, its impact on the domestic on the wider exchange rate market is insignificant.

Building Foreign Reserve in Nigeria: The Role of Oil and Non-oil Exports (Published)

This paper provides empirical evidence linking exports and foreign aid to international reserve accumulation. Country-specific data spanning from 1981-2015 on oil and non-oil exports and foreign aid in Nigeria were sourced from Central Bank of Nigeria Statistical Bulletin and analyzed using error correction mechanism (ECM) in addition to unit root and cointegration tests. As observed from the Augmented Dickey-Fuller test unit root, the variables are mixed integrated. Long run relationship was established amongst the series from the Johansen cointegration test result. The parsimonious ECM that lagged values of oil exports impact positively on foreign reserve holding. 1 percent increase in lag two of oil exports leads to 0.367 percent in the external reserve. Similarly, the first lag of non-oil exports is positively linked to external reserve. With 1 percent increase in non-oil exports, international reserve increases by 0.499 percent. The error correction estimate (-0.5099) indicates that the model is well behaved as any short run disequilibrium in the system is reconciled at the speed of 50.9 percent to achieve long run equilibrium position. On the basis of the findings, it is concluded that exports are helpful in boosting the foreign reserve holding in Nigeria. Thus, this paper recommends for the diversification of the export base in order to keep the foreign reserve holding on the path of rapid and sustainable growth.

The Determinants of Foreign Reserves in Nigeria (Review Completed - Accepted)

It has been seen that Foreign exchange reserves adequacy is a key component of good macroeconomic management. The modified version of the buffer stock model was applied to assess the determinants of foreign reserve in Nigeria. The study regressed foreign reserve variable on macroeconomic variables: real income, interest rate differential (a measure of opportunity cost), exchange rate volatility, financial openness, current account vulnerability, benchmark stock of reserves, and the demand for foreign exchange. In order to avoid any spurious regression results, the time series data from 1970 -2010 was subjected to stationarity tests. The ADF cointegration procedure used suggested the existence of long run relationships. Hence, the short run dynamics was examined by means of an error correction model. The empirical evidence shows that growth in Nigeria’s foreign reserves is not influenced in the long run by current account vulnerability (proxied by trade opennes), the opportunity cost of holding reserves (DID) and the benchmark stock of reserves but by other determinants such as the real Gross Domestic Products (Y), exchange rate volatility (Ev), financial openness (Fop), and the demand for foreign exchange (DFex).
