Fiscal, Monetary Policy, Trade Policies, and the Economy in Nigeria

Abstract

This study investigated the complex interrelationships between fiscal policy, monetary policy, trade policies and economic growth in Nigeria, employing a comprehensive econometric analysis using the Autoregressive Distributed Lag (ARDL) model. By analyzing quarterly time series data spanning from 1981 to 2023, the research explores both the long-run equilibrium relationships and short-run dynamics among the key macroeconomic policy variables and economic performance indicators. The results of the ARDL bounds test indicate a significant cointegrating relationship, suggesting that fiscal, monetary, and trade policies are jointly associated with longterm economic growth in Nigeria. The empirical findings reveal that fiscal and monetary policies exert a positive and statistically significant impact on economic growth. Specifically, increased government spending and prudent monetary management such as appropriate money supply and interest rate adjustments have contributed to improved macroeconomic performance. In contrast, trade policies were found to have a negative impact on economic growth, which may reflect challenges such as trade imbalances, poor implementation of trade agreements, and over-reliance on imports. Furthermore, the error correction mechanism (ECM) analysis shows a high speed of adjustment; indicating that short-term deviations from the long-run equilibrium are corrected relatively quickly, further confirming the stability of the underlying relationships. This study offers valuable insights for policymakers, emphasizing the need for better coordination and consistency among fiscal, monetary, and trade policy measures. It also contributes to the body of literature examining the nexus between macroeconomic policy frameworks and economic development, providing practical guidance for enhancing Nigeria’s policy effectiveness and long-term growth prospects.
