Social capital is fundamentally concerned with resources in social relations. This Handbook brings together leading scholars from around the world to address important questions on the determinants, manifestations and consequences of social capital. Various mechanisms of formal and informal social involvement, its relationship with other forms of social exclusion and its role in civic, instrumental and expressive domains of our socio-economic and community lives are explored. This unique Handbook: combines cutting-edge theory with appropriate data and methods; explores the mechanisms of formal and informal social involvement including the role of parental class and cultural influence, and the consequences for our personal and community lives; links social capital with other domains of social inequality such as cultural practice and philanthropic behaviour in an in-depth examination of the social stratification processes; conducts a thorough analysis of formal and informal social involvement, and bonding and bridging social ties on trust, tolerance, community cohesion, educational attainment, labour market position, quality of life and ethnic entrepreneurism; analyses social capital as both an outcome and as a mediating variable at the micro, meso and macro levels. Accessible yet rigorous, this Handbook presents a challenge to both social capital researchers interested in explaining social inequality and to policy-makers with responsibility for designing effective measures for combating social exclusion. It will also be essential reading for students in sociology, political science, developmental economics and management studies.
