We review the literature in sociology and related fields on the fast global growth of consumer credit and debt and the possible explanations for this expansion. We describe the ways people interact with the strongly segmented consumer credit system around the world—more specifically, the way they access credit and the way they are held accountable for their debt. We then report on research on two areas in which consumer credit is consequential: its effects on social relations and on physical and mental health. Throughout the article, we point out national variations and discuss explanations for these differences. We conclude with a brief discussion of the future tasks and challenges of comparative research on consumer credit.

This paper criticizes traditional approaches to stratification, which suggest that education contributes to inequality solely by endowing people with different amounts of human capital (knowledge and skills) or credentials. What these approaches overlook is the social component of education-friends, acquaintances and other connections one accumulates while in school. These connections reduce the uncertainty inherently present in the hiring process by compensating for lack of information with trust. We argue that social capital gained while in school has an independent effect on individual income, and show how this effect varies by education and experience levels. Conceptualizing schooling as an important source of social capital and finding ways to disentangle the effects of human and social capital on individual income are a contribution that economic sociologists can make to the study of education and inequality.
