Exchange rate volatility and export growth in Nigeria

This article examines the impact of exchange rate volatility on Nigeria's exports to its most important trading-partner–the United States over the quarterly period January 1980 to April 2001. Using cointegration and vector error correction (VECM) framework, empirical tests indicate the presence of a unique cointegrating vector linking real exports, real foreign income, relative export prices and real exchange rate volatility in the long run. Furthermore, the results show that increases in the volatility of the real exchange rate raise uncertainty about profits to be made which exert significant negative effects on exports both in the short- and long-run. Our results also show that improvements in the terms of trade (represented by declines in the real exchange rate) and real foreign income exert positive effects on export activity. Most importantly, we found that the trade liberalization and economic reform policies implemented in the post-1986 structural adjustment period contributed to Nigeria's export performance. Overall, our findings suggest that Nigeria's exporting activities can be further boosted by policies aimed at achieving and maintaining a stable competitive real exchange rate.
