Trade Openness, Exchange Rate Dynamics and Unemployment in ECOWAS Countries: A Panel Econometric Analysis

Aims: This study examined the relationship between trade openness, exchange rates, and unemployment in ECOWAS countries. It investigated whether increased trade openness reduces or exacerbates unemployment and how exchange rate fluctuations impact labor markets. The analysis is grounded in a theoretical framework that integrates trade theory, labor market dynamics, and macroeconomic stability to contextualize the empirical findings.

Study Design: A panel econometric approach was employed, utilizing both Fully Modified Ordinary Least Squares (FMOLS) and Dynamic Ordinary Least Squares (DOLS) methods to ensure robust estimates.

Place and Duration of Study: The study covered 15 ECOWAS countries, with panel data spanning from 1991 to 2020, sourced from the World Bank Development Indicators (WDI).

Methodology: The research applied panel unit root tests (Im, Pesaran, and Shin; ADF; and Phillips-Perron) to determine variable stationarity. Pedroni co-integration tests confirm long- term relationships among trade openness, exchange rates, GDP, population growth, and unemployment. The FMOLS and DOLS models are then used to estimate the effects of these variables on unemployment.

Results: Findings indicate that trade openness has a positive and statistically significant effect on unemployment (FMOLS: 5.43, p<0.01; DOLS: 2.71, p<0.01), suggesting that increased trade is associated with higher unemployment. Conversely, exchange rates (FMOLS: -3.47, p<0.01; DOLS: -3.63, p<0.01) and GDP growth (FMOLS: -3.26, p<0.01; DOLS: -2.48, p<0.01) negatively correlate with unemployment, implying that economic growth and stable exchange rates help reduce joblessness. The population growth rate is significant in the DOLS model (1.87, p<0.10), indicating a nuanced effect on unemployment. The models demonstrate high explanatory power (R² = 0.88 for FMOLS; R² = 0.95 for DOLS).

Conclusion: The study highlights the complex interplay between trade, exchange rates, and employment in ECOWAS countries. Policymakers should balance trade policies with labor market reforms to mitigate unemployment. Stabilizing exchange rates and fostering economic growth through industrial and workforce development programs are crucial strategies for sustainable employment generation. However, the study acknowledges limitations, including potential omitted variable bias and the challenges of generalizing findings across diverse economies. Future research could explore sector-specific impacts of trade openness and exchange rate volatility, as well as the role of institutional quality in shaping labor market outcomes.
