Abstract :
This study assessed the relationship between
exchange rate volatility and economic growthin the west
African monetaryzone (WAMZ). The study employed
annualized panel dataset that spans from 1989 to 2019,
using analytical technique ofthe fixed-effect panel
dynamic threshold model.The GARCH technique was
employed to ascertain the exchange rate volatility of the
selected WAMZ Member States including, Nigeria,
Ghana, and The Gambia, while Guinea, Sierra Leone
and Liberia were dropped from the observation owning
to non-availability of data. The results show thatthe first
lag of real GDP(Rgdp), has a significant and positive
relationship with the dependent variable. While
exchange rate volatility has a negative but insignificant
relationship with economic growth. The study also
indicate that inflation is negatively and significantly
related to economic growth within the countries,
whereas interest rate is positively and insignificantly
related to economic growth. Given the importance of
exchange rate on economic growth through facilitating
international trade and investment in the WAMZ region,
these countries’ monetary authorities, government and
other relevant agencies should adopt measures that will
discourage imports and encourage exports and adapt an
exchange rate policy that principally seeks to stabilize
exchange rates with the zone.
