  Productive capacity has emerged as a critical indicator of long-term economic development, particularly for regions undergoing rapid structural transformation, such as Sub-Saharan Africa (SSA). Despite increasing global interest, the key drivers of productive capacity in SSA remain insufficiently explored, especially within the context of tourism and migration. Existing studies predominantly rely on GDP-based growth models and often examine tourism and migration separately, overlooking their combined influence on structural development. Moreover, the role of institutional quality in shaping productive capacity is under-investigated. This study examines how international tourism and migration affect productive capacity growth in SSA, while also considering the contributions of urbanization, trade openness, and institutional quality. Using panel data from 38 SSA countries between 2011 and 2021, the analysis employs a dynamic System Generalized Method of Moments (System GMM) estimator to address endogeneity, unobserved heterogeneity, and simultaneity among variables. The results indicate that international tourism and migration exert positive and statistically significant effects on productive capacity. Institutional quality emerges as the most influential driver, followed by urbanization and trade openness. These findings underscore the importance of structural and governance-related factors in enhancing the region’s productive capacity. Tourism and migration contribute meaningfully to productive capacity growth; however, their impact is substantially conditioned by the quality of governance and structural enablers. Policymakers should adopt sustainable tourism strategies, strengthen security and infrastructure, develop migration-friendly frameworks, enhance human capital, and prioritize institutional reforms to maximize long-term productive capacity in SSA.

  The nexus between the agricultural sector, manufacturing sector, and FDI has been a topic of debate over the years. While the fundamental role of FDI in the growth of the overall economy has been widely recognized, findings of existing literature have remained unclear and inconclusive on how the impact of FDI varies across these distinct sectors, especially within the context of developing countries like Nigeria. This study aims to provide a comprehensive comparative analysis of the impact of FDI and other capital inflows on Nigeria’s agricultural and manufacturing sectors between 1980 and 2021. Using annual time-series data from the World Bank’s World Development Indicators (WDI) and the Central Bank of Nigeria (CBN), the study employs the Autoregressive Distributed Lag (ARDL) modelling approach. Four sector-specific ARDL models were specified, each subjected to extensive diagnostic and robustness checks to ensure the reliability of the estimates. The findings reveal a contrasting effect: while FDI exerts no statistically significant influence on manufacturing output, it has a strong and transformative impact on agricultural performance. In addition, other capital inflows, including official development assistance, development finance, and remittances, were found to significantly influence both sectors. The study concludes that FDI is not a universal driver of growth, and its effectiveness depends on sectoral characteristics, investment type, and policy environment. It contributes to the literature by offering one of the first sector-specific comparative analyses of capital flows in Nigeria, providing evidence to guide policies aimed at shifting the economy from consumption-driven patterns toward sustainable, production-oriented growth.
