The Russell Sage Foundation dedicates itself exclusively to strengthening the methods, data, and theoretical core of the social sciences as a means of diagnosing social problems and improving social policies. The Foundation is accepting letters of inquiry for its Behavioral Economics; Future of Work; Race, Ethnicity, and Immigration; and Social Inequality programs. The Behavioral Economics program supports research that uses behavioral insights from psychology and other social sciences to examine and improve social and living conditions in the United States. The Future of Work program supports research on the causes and consequences of changes in the quality of jobs for less- and moderately-skilled workers and their families. The Race, Ethnicity, and Immigration program seeks investigator-initiated research proposals on the social, economic, and political effects of the changing racial and ethnic composition of the U.S. population, including the transformation of communities and ideas about what it means to be American. The Social Inequality program supports research on whether rising economic inequality has affected social, political, and economic institutions, and the extent to which increased inequality has affected equality of opportunity, social mobility, and the intergenerational transmission of advantage. Awards are available for research assistance, data acquisition, data analysis, and investigator time for conducting research and writing up results.
