This essay explores the development of the social resources theory, which examines the relationship between embedded resources in social networks and socioeconomic attainment. The theory posits that social capital, both in terms of access and mobilization of these resources, enhances the chances of achieving better statuses. Social capital is influenced by initial positions in social hierarchies and the extensivity of social ties. The essay reviews the theoretical and empirical foundations of this research, including the contributions of Mark Granovetter's work on the strength of weak ties and the convergence of social resources theory with social capital theory. It discusses two main processes: the access to social capital and the mobilization of social capital in the status attainment process. The essay also examines the joint effects of accessed and mobilized social capital and identifies critical issues and future research directions, such as the inequality of social capital and the relationship between social capital and human capital.This essay explores the development of the social resources theory, which examines the relationship between embedded resources in social networks and socioeconomic attainment.
