Similarity breeds connection. This principle—the homophily principle—structures network ties of every type, including marriage, friendship, work, advice, support, information transfer, exchange, comembership, and other types of relationship. The result is that people's personal networks are homogeneous with regard to many sociodemographic, behavioral, and intrapersonal characteristics. Homophily limits people's social worlds in a way that has powerful implications for the information they receive, the attitudes they form, and the interactions they experience. Homophily in race and ethnicity creates the strongest divides in our personal environments, with age, religion, education, occupation, and gender following in roughly that order. Geographic propinquity, families, organizations, and isomorphic positions in social systems all create contexts in which homophilous relations form. Ties between nonsimilar individuals also dissolve at a higher rate, which sets the stage for the formation of niches (localize...

Birds of a Feather: Homophily in Social Networks

This paper reviews the origins and definitions of social capital in the writings of Bourdieu, Loury, and Coleman, among other authors. It distinguishes four sources of social capital and examines their dynamics. Applications of the concept in the sociological literature emphasize its role in social control, in family support, and in benefits mediated by extrafamilial networks. I provide examples of each of these positive functions. Negative consequences of the same processes also deserve attention for a balanced picture of the forces at play. I review four such consequences and illustrate them with relevant examples. Recent writings on social capital have extended the concept from an individual asset to a feature of communities and even nations. The final sections describe this conceptual stretch and examine its limitations. I argue that, as shorthand for the positive consequences of sociability, social capital has a definite place in sociological theory. However, excessive extensions of the concept may j...

Social Capital: Its Origins and Applications in Modern Sociology

This chapter aims to develop one of perhaps multiple specifications of embeddedness, a concept that has been used to refer broadly to the contingent nature of economic action with respect to cognition, social structure, institutions, and culture. Research on embeddedness is an exciting area in sociology and economics because it advances understanding of how social structure affects economic life. The chapter addresses propositions about the operation and outcomes of interfirm networks that are guided implicitly by ceteris paribus assumptions. While economies of time due to embeddedness have obvious benefits for the individual firm, they also have important implications for allocative efficiency and the determination of prices. Under the conditions, social processes that increase integration combine with resource dependency problems to increase the vulnerability of networked organizations. The level of investment in an economy promotes positive changes in productivity, standards of living, mobility, and wealth generation.

Social Structure and Competition in Interfirm Networks: The Paradox of Embeddedness

A growing number of sociologists, political scientists, economists, and organizational theorists have invoked the concept of social capital in the search for answers to a broadening range of questions being confronted in their own fields. Seeking to clarify the concept and help assess its utility for organizational theory, we synthesize the theoretical research undertaken in these various disciplines and develop a common conceptual framework that identifies the sources, benefits, risks, and contingencies of social capital.

Social Capital: Prospects for a New Concept

The Behavioral Model of Health Services Use was initially developed over 25 years ago. In the interim it has been subject to considerable application, reprobation, and alteration. I review its development and assess its continued relevance.

4 – Ideologies of Inequality and Their Transformation in the Periphery: The Case of Latin America

The implications of U.S. migration policy are evaluated with a focus on the demographic and sociological aspects labor market effects and economic implications of Mexican migration to the United States. (ANNOTATION)

[Immigration and the international system: some characteristics of recent Mexican immigrants to the United States].

We summarize the history of Latin American urbanization with a focus on the evolution of cities from the colonial and post-colonial eras to the adoption of the import-substitution model of development and its subsequent replacement by a neoliberal adjustment model. Consequences for the urban system of both import-substitution and neoliberal policies are examined, with a focus on the evolution of the urban population and trends in several strategic areas. We examine indicators of unemployment and informal employment; poverty and inequality; and urban crime and victimization rates as they evolved from the import-substitution era to the implosion of the neoliberal model that replaced it in the early twenty-first century. The consequences for cities of the disastrous application of this model are summarized as a prelude to the analysis of more recent trends. Based on the latest statistical indicators available, we document a significant decline in unemployment and economic inequality in six Latin American nations that jointly comprise 80 percent of the population of the region. Employment in the informal sector also declined steadily, although it still comprises a large proportion of Latin American labor markets. Consequences of this situation for the citizenry and alternative government policies to address it are discussed.
