Empirical evidence is scanty on the nexus between caregivers’ nutrition knowledge, market accessibility, and preschool children’s dietary diversity in remote communities of Africa’s most populous country, Nigeria. To fill this gap, this study evaluated the effects of caregivers’ nutrition knowledge and access to food market on dietary diversity of preschool children. We used cross-sectional data from four hundred households selected from twenty remote communities in Southeast Nigeria. The study adopted instrumental variable regression to estimate the impacts of nutrition knowledge and food market access on preschool children’s dietary diversity. The findings show that in remote communities, caregivers’ nutrition knowledge and households’ closeness to the market improved preschool children’s dietary diversity. The study demonstrates the potential of improving preschool children’s nutrition outcomes through enhancing access to food market and the nutrition knowledge of the caregivers.

Empirical evidence is lacking on the nexus between coffee commodity output, climate change, and commodity price volatility of Africa’s most populous country, Nigeria, and other developing countries. To fill this gap, this study analyzed the reaction of coffee output to climate change and commodity price volatility. We used secondary data from 1961 to 2015 from reliable sources for Nigeria. The study adopted generalized autoregressive conditional heteroscedasticity (GARCH), autoregressive conditional heteroscedasticity (ARCH), and fully modified ordinary least square (FMOLS) in analysis of coffee output reaction to climate change and commodity price volatility. The findings show that coffee output in Nigeria is influenced by climate change and the international commodity price of coffee. The study demonstrates the potential benefits of improving coffee output and export through climate mitigation and adaptation measures and revival of agricultural commodity marketing in Nigeria and other developing countries.

Employment relations in small-scale enterprises in Nigeria are influenced by power dynamics, labor regulations, cultural norms, and economic conditions, creating challenges for worker representation, and job security. This study focuses on the Nigerian context to examine the complexities of labor relations in these enterprises, emphasizing informal employment structures, employer-employee power asymmetries, and workforce management strategies. Analyzing regulatory gaps and sociocultural influences reveals the vulnerabilities of workers and explores employer-driven initiatives that can enhance labor conditions. The findings underscore the need for stronger labor protections, structured employment policies, and proactive human resource management to balance business sustainability with equitable labor practices. The study introduces the power and labor dynamics model as a conceptual framework to understand employment relations in small-scale enterprises. This model provides insights into how employer control, worker agency, and regulatory interventions interact to shape labor outcomes. The research concludes that integrated policy measures and employer-led strategies are essential for fostering sustainable and equitable employment conditions in Nigeria’s informal labor market. Recommendations for future studies include examining the impact of digitalization, automation, and alternative worker representation mechanisms on employment relations in small-scale enterprises.

Outsourcing has become an essential strategy for businesses seeking cost efficiency while maintaining innovation. However, the challenge of balancing cost reduction with service quality and technological advancement remains a pressing concern. This study explores the complexities of outsourcing decisions by employing a systematic literature review to synthesize insights from reputable scholarly sources. The research introduces the Cost-Innovation Balance Model (CIBM), which provides a structured framework for understanding the interplay between cost efficiency, supplier collaboration, digital transformation, and risk mitigation. Findings highlight that while outsourcing enhances operational efficiency, it requires careful management to prevent negative impacts on service quality, intellectual property security, and long-term sustainability. AI-driven analytics, automation, and incentive-based contracts emerge as crucial tools for optimizing outsourcing partnerships. The study underscores the importance of aligning outsourcing strategies with broader organizational goals to achieve sustainable competitive advantage. Policy and managerial implications suggest that firms should integrate technology-driven decision-making and regulatory compliance measures to enhance outsourcing effectiveness. This research contributes to the ongoing discourse on outsourcing by offering a conceptual model that can guide businesses in navigating the trade-offs between cost efficiency and innovation sustainability
