ABSTRACT
This chapter discusses a particular kind of networks of people whose members are connected directly or indirectly by social capital. Social capital-rich networks convey important benefits to network members. It explores the structure of networks and how different network structures influence how networks function. The chapter describes the shared traits, or kernels of commonality, around which networks are organized, and follow up with a discussion of network maintenance requirements. It explains what kinds of institutions are required for networks to function effectively; what kinds of goods, including socio-emotional goods (SEGs), are exchanged within networks; and how network structure affects the effectiveness of networks. The permeability of networks whose membership requirements are inherited depends on the number of individuals possessing the trait. For major corporations, such as United Airlines, network maintenance is a major concern and may require network managers to readjust the institutions to changing economic or social conditions if the networks are to survive.
