Abstract
This study employs time series econometric techniques to examine
the dynamic relationship among economic growth, money supply, exchange rate and
inflation in The Gambia over the period 1966 to 2023. The empirical findings
reveal the existence of a long-run equilibrium relationship among the
variables, with money supply exerting a significant positive influence on
economic growth. Granger causality tests indicate a unidirectional causality
running from real GDP to the exchange rate, while inflation does not exhibit
any significant causal linkage with the other variables. The Vector Error
Correction Model (VECM) further underscores the pivotal role of money supply in
driving long-term growth, highlighting the importance of prudent monetary
policy and exchange rate stability for sustainable economic development.
Additionally, the analysis reveals that the trends in the time series data are
consistent with the statistical results in which money supply and economic
growth are positively correlated in the long run, whereas exchange rate
depreciation tends to fuel inflation. These findings underscore the critical
importance of maintaining currency stability to support The Gambia’s
macroeconomic performance.
