Julie joined CEPR in June 2020 as an economist on the domestic team, supporting research and policy efforts on a wide range of labor market issues. Her areas of research include household income volatility, precarious work, economic inequality, and poverty measurement.

Since then she worked on topics including job churn, housing, income instability, child welfare, and the care economy, with a particular focus on the working class and gender and racial disparities. With the increasing economic precarity facing many low- and middle-income families, she has focused on understanding how the 2021 expanded Child Tax Credit can reduce parental income shocks and other public policies that have the potential to stabilize work hours and income. Her work has been published in peer-reviewed journals such as Child Abuse and Neglect, Social Forces, and Housing Policy Debate, and her analysis has appeared in outlets ​such as BBC, CNBC, and The Wall Street Journal.

​C​ai earned ​her PhD in social welfare and public affairs from University of Wisconsin–Madison​. She is an external affiliate with the Columbia Center on Poverty and Social Policy. ​Previously she was ​a lecturer at Columbia University ​and a visiting fellow at the Federal Reserve Bank of Boston from 2022 to 2023.
