Nan Lin's essay explores the development of the social resources theory, which examines the relationship between embedded resources in social networks and socioeconomic attainment. The theory, viewed through the lens of social capital, suggests that social capital enhances the chances of attaining better statuses by accessing and mobilizing resources. Social capital depends on initial positions in social hierarchies and the extent of social ties. The essay discusses remaining critical issues and future research directions for this field. Status attainment involves mobilizing and investing resources for socioeconomic standing. Resources are valued goods in society, while values are normative judgments on these goods. Socioeconomic standings are valued resources attached to occupied positions, classified into personal and social resources. Personal resources are freely usable, while social resources are accessed through direct and indirect ties. The Blau-Duncan study (1967) established that achieved status (education, prior occupational status) was the most important factor in attained status. Subsequent studies have expanded on this, incorporating sociopsychological variables, status classes, structural entities, and comparative development. These studies have significantly amplified the original Blau-Duncan conclusion regarding the relative merits of achieved versus ascribed personal resources. In the last three decades, research has focused on the effects of social resources on attained statuses. The main proposition is that social resources significantly affect attained statuses beyond personal resources. Studies have examined theoretical explanations, measurements of social resources, empirical studies, and the relative importance of social resources compared to personal resources. These studies have been conducted in North America, Europe, and Asia, involving scholars from various nations and cultures. Granovetter's (1974) study of professional and managerial men in Newton, Massachusetts, suggested that those using interpersonal channels obtained more satisfactory jobs. Granovetter proposed a network theory for information flow, including the "strength of weak ties" hypothesis. However, he did not suggest that weaker ties lead to better job statuses. A small world study in upstate New York found that successful job search chains involved higher-status intermediaries, suggesting that access to hierarchical positions is critical in status attainment. A theory of social resources has emerged, emphasizing the macro-social structure with positions ranked by normatively valued resources. This structure has a pyramidal shape, with higher positions having fewer occupants and better views. Individuals within these constraints take actions for expressive and instrumental purposes. Instrumental actions, such as attaining status, benefit from contacts higher in the hierarchy. Three propositions were formulated: (a) the social resources proposition, (b) the strength of position proposition, and (c) the strength of ties proposition. These propositions remain valid in the framework of social capital theory, which complements and strengthens the development of a social theory focusing on the instrumental utility of accessed and mobilized resources. Research on the relationships between social resources and status attainment examines two processes: access to social capital and mobilization of social capital.
