This study by Evans Yeboah and Václav Adamec, published in the Journal of Social and Economic Development (Springer Nature, June 9 2025), examines the effects of investment and trade on economic performance across twelve ECOWAS member states from 1993 to 2022. Using PMG-ARDL and NARDL estimation techniques, the paper finds that gross capital formation and trade openness positively influence long-run GDP per capita growth, whereas population growth, labor participation, unemployment, merchandise trade, and FDI exert negative effects. External debt is statistically insignificant in the long term. In the short term, increases in FDI and merchandise trade enhance income growth. Nonlinear estimations show that both increases and decreases in FDI dampen growth, while trade expansion boosts economic performance. The authors recommend promoting trade liberalization, improving FDI quality, ensuring sustainable debt management, and implementing labor-market reforms and export diversification strategies.

This communication aims to analyze the cross-border migrations of women traders in sub-Saharan Africa. To carry out this study, we used a qualitative methodology comprising a semi-structured interview guide addressed to a number of 42 people, with 6 respondents per country. The approaches that are: historical, informality, comprehensive of Max Weber and the comparative method of Durkheim Émile were used for theoretical illumination. It follows from this study that cross-border migrations of women traders constitute a survival strategy and a fight against unemployment. In addition, they weaken the macroeconomy by promoting the flourishing of the informal economy. Thus, they allow the greatest number of vulnerable households to survive.
