Justin Ross is a public finance economist specializing in state and local tax policy. Ross joined O'Neill in 2008 and teaches public revenue theory, public managerial economics, and benefit-cost analysis. He is a two-time recipient of IU's Trustees Teaching award, in 2013 and 2009.

Ross's primary research interests include property tax-related issues such as assessment and zoning. His published works explore local governments' use and access to the property tax by examining how it affects the politics, fiscal capacity, land use regulation, and community decisions. Ross's articles have appeared in the top public finance, economics, and public administration journals including: National Tax Journal, Land Economics, Journal of Environmental Economics & Management, Public Finance Review, Public Budgeting & Finance, Journal of Public Administration Research & Theory, Contemporary Economic Policy, Public Finance & Management, and the Journal of Real Estate and Finance Economics.

His projects include the study of school district income taxes--a relatively new phenomenon in local public finance, as well as property reassessments and their impact on property tax revenue. Ross also explores the relationship that tax amnesty programs have with state and local tax administration, and their resulting behavior responses.
