Corporate market power touches virtually every facet of American life—from health care costs and access to grocery stores to our environment and the strength of our democratic institutions. Public benefits programs, such as the Supplemental Nutrition Assistance Program (SNAP) and Medicaid, provide essential protections for workers and families from the harms of concentrated market power, including the prevalence of low-paid work. However, little attention has been paid to the complex relationships between public benefits and corporate market power. This working paper examines some of the relationships between corporate market power and public benefits and spotlights opportunities for further exploration of this emerging area of research.
