He conducts research at the intersection of three fields within economics. First, there is public finance, the field of economics that analyzes government taxation and spending, using models of choice to predict the effects of policy and economic notions of well-being to measure the policy’s benefit or harm to consumers. Second is household finance, the branch of economics that focuses on the financial decisions, saving, borrowing and insurance, at the household level. Finally, there is behavioral economics, the branch of economics that uses insights from psychology and empirical evidence to explore the ways in which human behavior deviates from the neoclassical model of consumer decision-making. His current research topics include income tax policy, social security, retirement and retirement savings, and the interaction between employer-provided benefits and labor market outcomes.
