Scheidel's research focuses on ancient social and economic history, with particular emphasis on historical demography, labor, and state formation. More generally, he is interested in comparative and transdisciplinary approaches to the study of the premodern world, and has been trying to build bridges between the humanities, the social sciences, and the life sciences.
The most frequently cited active-duty Roman historian adjusted for age in the Western Hemisphere, Scheidel is the author or (co-)editor of 17 books, has published well over 200 articles, chapters, and reviews, and has lectured in 26 countries. His most recent books are "The Great Leveler: Violence and the History of Inequality from the Stone Age to the Twenty-First Century" (2017), "On Human Bondage: After Slavery and Social Death" (2017, co-edited with John Bodel), "State Power in Ancient Rome and China" (2015, ed.), "Fiscal Regimes and the Political Economy of Premodern States" (2015, co-edited with Andrew Monson), "The Oxford Handbook of the State in the Ancient Near East and Mediterranean" (2013, co-edited with Peter Bang), "The Cambridge Companion to the Roman Economy" (2012, ed.), "The Oxford Handbook of Roman Studies" (2010, co-edited with Alessandro Barchiesi), "Rome and China: Comparative Perspectives on Ancient World Empires" (2009, ed.), "The Dynamics of Ancient Empires" (2009, co-edited with Ian Morris), and "The Cambridge Economic History of the Greco-Roman World" (2007, co-edited with Ian Morris and Richard Saller).
