Benefits Cliffs and Effective Marginal Tax Rates

I study how the structure of the U.S. tax and transfer system - featuring phase-outs as income rise - create disincentives for economic mobility of low- and moderate-income families.

Below is the full list of my work that explores this issue.

Marginal Net Taxation of American Labor Supply
With David Altig, Alan Auerbach, Laurence Kotlikoff, and Victor Ye

The U.S. has a plethora of federal and state tax and benefit programs, each with its own work incentives and disincentives. This paper uses the Fiscal Analyzer (TFA) to assess how these policies, in unison, impact work incentives. TFA is a life-cycle, consumption-smoothing program that incorporates household borrowing constraints and all major federal and state fiscal policies.

Benefits Cliffs and the Financial Incentives for Career Advancement: A Case Study of the Health Care Services Career Pathway
With David Altig, Alexander Ruder, and Ellie Terry

Benefits cliffs, which occur when earnings gains are offset by the loss of public benefits, have long been recognized to create financial disincentives for low-income individuals to earn more income. In this paper, we develop a new methodology to study benefits cliffs in the context of career advancement. We illustrate the change in net financial resources for an individual pursuing the health care services career pathway from certified nursing assistant (CNA) to licensed practical nurse (LPN) to registered nurse (RN).

Restructuring the Eligibility Policies of the Child Care and Development Fund to Address Benefits Cliffs and Affordability
With Brittany Birken, Alexander Ruder, and Ellie Terry

This paper explores how the current eligibility policies of the federal Child Care and Development Fund (CCDF) create affordability challenges and benefits cliffs that act as barriers to economic self-sufficiency. By examining Florida data and policies, the authors demonstrate how the program’s existing co-payment schedule affects the same hypothetical family living in two contrasting Florida counties: one with state median living costs and one with high living costs.

The Racial Income Gap and Benefits Cliffs

Income gaps along racial lines are the result of long-standing structurally discriminatory policies across U.S. institutions. Although laws have changed, the legacy of these policies still affects people today. This article examines how benefits cliffs differentially affect minority populations.

Amid the COVID-19 Crisis, a Tale of Two Southeastern Cities
With John Robertson, Alexander Ruder, and Ellie Terry
