Knowledge that Transforms

We propose a theoretical framework on the structural sources and spatially embedded nature of three mechanisms that produce collective efficacy for children. Using survey data collected in 1995 from 8,782 Chicago residents, we examine variations in intergenerational closure, reciprocal local exchange, and shared expectations for informal social control across 342 neighborhoods. Adjusting for respondents’ attributes, we assess the effects of neighborhood characteristics measured in the 1990 census and the role of spatial interdependence. The results show that residential stability and concentrated affluence, more so than poverty and racial/ethnic composition, predict intergenerational closure and reciprocal exchange. Concentrated disadvantage, by contrast, is associated with sharply lower expectations for shared child control. The importance of spatial dynamics in generating collective efficacy for children is highlighted—proximity to areas high in closure, exchange, and control bestows an advantage above and beyond the structural characteristics of a given neighborhood. Moreover, spatial advantages are much more likely to accrue to white neighborhoods than to black neighborhoods.

Recent scholarship claims that bilingualism has a positive effect on the academic achievement of immigrant children. According to this perspective, growing up speaking two languages is beneficial because it stimulates cognitive development and allows immigrants a means of resisting unwanted assimilation. Immigrant children who are fluent bilinguals can use their native-language ability to maintain beneficial aspects of their ethnic culture while accommodating to the linguistic demands of an English-speaking society. Using data on first- and second-generation Asian American students from the 1988 National Educational Longitudinal Study, we test for these hypothesized effects of bilingualism. We find no evidence that bilingualism per se has a positive effect on achievement. Instead, speaking a native language with parents has a temporary positive effect if the parents are not proficient in English. These results indicate that the academic importance of bilingualism is transitional: The educational benefits of delaying linguistic assimilation exist only before immigrant parents achieve a moderate level of English-language proficiency.

I investigate how social embeddedness affects an organization's acquisition and cost of financial capital in middle-market banking—a lucrative but understudied financial sector. Using existing theory and original fieldwork, I develop a framework to explain how embeddedness can influence which firms get capital and at what cost. I then statistically examine my claims using national data on small-business lending. At the level of dyadic ties, I find that firms that embed their commercial transactions with their lender in social attachments receive lower interest rates on loans. At the network level, firms are more likely to get loans and to receive lower interest rates on loans if their network of bank ties has a mix of embedded ties and arm's-length ties. These network effects arise because embedded ties motivate network partners to share private resources, while arm's-length ties facilitate access to public information on market prices and loan opportunities so that the benefits of different types of ties are optimized within one network. I conclude with a discussion of how the value produced by a network is at a premium when it creates a bridge that links the public information of markets with the private resources of relationships.

We investigate the forces affecting the distribution of income by analyzing an unbalanced panel of information for 16 industrialized countries for the years 1966 through 1994. Income inequality is measured with the Gini coefficient of equivalent disposable income; individuals are the unit of analysis; the statistical analysis uses panel methods. The results suggest that many factors affect the development of income inequality. Some factors are strictly economic: A decreased industrial sector generally fosters inequality, and some support is found for the view that increased trade of manufactured goods from developing countries is also a factor. Other forces are outside a strictly defined market sphere: Low inequality is found when a large proportion of the labor force belongs to a trade union and also when there is a large public sector. In addition, demographic circumstances are important, since the proportion of the population under age 15 has a positive effect on inequality. We find, however, no association between the unemployment rate and inequality.

I extend the theoretical domain of sociology into an area of social psychology that heretofore has been the exclusive domain of psychologists. Specifically, I develop a social structural perspective on the choice shifts that individuals make within groups. During interpersonal discussions of issues, choice shifts occur when there is a difference between group members’ mean final opinion and their mean initial opinion. Explanations of choice shifts have emphasized group-level conditions (e.g., a norm, a decision rule, a pool of persuasive arguments, a distribution of initial opinions). I argue that choice shifts are a ubiquitous product of the inequalities of interpersonal influence that emerge during discussions of issues. Hence, I bring choice shifts squarely into the domain of a structural social psychology that attends to the composition of networks of interpersonal influence and into broader sociological perspectives concerned with the formation of status structures.
