Elgar Research Agendas outline the future of research in each area. Leading scholars are given the space to explore their subject in provocative ways and map out the potential directions of travel. They are relevant but also visionary. This innovative Research Agenda investigates the complex relationship between social capital and economic development. Expert authors review existing research alongside recent trends, emphasizing the nuanced, context-specific effects of social capital on economic outcomes. Drawing on in-depth case studies from local to national levels, chapters examine the role of social capital in informal economies, socio-economic planning, and rural prosperity. They further assess diverse methods and frameworks including econometrics, network analysis, bibliometrics, and human ecology economics, providing novel perspectives and identifying important avenues for future research. Incisive contributions also consider various definitions of economic development, ultimately highlighting the necessity of multidisciplinary approaches for the successful implementation of social capital strategies. Presenting cutting-edge insights into research on social capital and economic development, this Research Agenda is an essential tool for students and scholars in development studies, economics, sociology and social policy. Its consideration of policy implications of social capital research through relevant practical examples also makes it an invaluable resource for policymakers.
