Individual social capital: Accessibility and mobilization of resources embedded in social networks

The objective of the present paper is to characterize the structure of individual social networks and to provide new insights into the underlying mechanism of individual social capitalization process. In particular, we put to the test three main assumptions underlying Lin's seminal explanatory model of individual social capital determinants (Lin, 2001). We analyzed the results of an extensive and specifically designed survey on personal networks in Spanish society (OSIM, 2011). Our findings, based on the use of Principal Component Analysis (PCA), regression and structural methods allow us to complement Lin's general model distinguishing accessibility and mobilization of social resources. Furthermore, the empirical evidence suggests the need for introducing a significant distinction between instrumental-expert and expressive mobilization. Finally, our analysis allows us to identify the main determining factors of both forms of capitalization of personal relations. (C) 2016 Elsevier B.V. All rights reserved.
