Economic insecurity describes the risk of economic loss faced by workers and households as they encounter the unpredictable events of social life. Our review suggests a four-part framework for studying the distribution and trends in these economic risks. First, a focus on households rather than workers captures the microlevel risk pooling that can smooth income flows and stabilize economic well-being. Second, insecurity is related to income volatility and the risk of downward mobility into poverty. Third, adverse events such as unemployment, family dissolution, or poor health commonly trigger income losses. Fourth, the effects of adverse events are mitigated by insurance relationships provided by government programs, employer benefits, and the informal support of families. Empirical research in these areas reveals high levels of economic insecurity among low-income households and suggests an increase in economic insecurity with the growth in economic inequality in the United States.

This essay reviews and evaluates recent comparative social science scholarship on healthcare systems. We focus on four of the strongest themes in current research: (1) the development of typologies of healthcare systems, (2) assessment of convergence among healthcare systems, (3) problematization of the shifting boundaries of healthcare systems, and (4) the relationship between healthcare systems and social inequalities. Our discussion seeks to highlight the central debates that animate current scholarship and identify unresolved questions and new opportunities for research. We also identify five currents in contemporary sociology that have not been incorporated as deeply as they might into research on healthcare systems. These five “missed turns” include an emphasis on social relations, culture, postnational theory, institutions, and causal mechanisms. We conclude by highlighting some key challenges for comparative research on healthcare systems.

Has income insecurity increased among U.S. children with the emergence of an employment-based safety net and the polarization of labor markets and family structure? We study the trend in insecurity from 1984-2010 by analyzing fluctuations in children's monthly family incomes in the Survey of Income and Program Participation. Going beyond earlier research on income volatility, we examine income insecurity more directly by analyzing income gains and losses separately and by relating them to changes in family composition and employment. The analysis provides new evidence of increased income insecurity by showing that large income losses increased more than large income gains for low-income children. Nearly one-half the increase in extreme income losses is related to trends in single parenthood and parental employment. Large income losses proliferated with the increased incidence of very low incomes (less than $150 per month). Extreme income losses and very low monthly incomes became more common particularly for U.S. children of nonworking single parents from the mid-1990s.
