Casey Mulligan’s research centers on incentives to save and work and how the economy affects policy. He also has studied social security, aging and retirement, and has examined wage inequality between men and women.
He is the author of The Redistribution Recession: How Labor Market Distortions Contracted the Economy (2012) and Side Effects: The Economic Consequences of the Health Reform (2015). Redistribution, or subsidies and regulations intended to help the poor, unemployed and financially distressed, have changed in many ways since the onset of the recent financial crisis, he contends.
Mulligan studies the transmission of family work values and wealth between generations. In the book Parental Priorities and Economic Inequality (1997), he shows that parents share their resources unequally, giving more to those children with whom they spend more time.
