David Jones’ research focuses on evaluating the impact of public health programs and policies, examining the composition of health care systems in the U.S. and the quality and cost of care delivered by systems, and assessing health policies and programs more broadly.
Jones currently leads the evaluation of several public health programs and policies, including studies of (1) the impact of sugar-sweetened beverage taxes on prices, purchases, and consumption among families and children, (2) fiscal and economic impacts of legalizing recreational marijuana use in Massachusetts on state and local budgets, (3) head impacts among youth football players, including a randomized control trial of an alternative tackling technique and robot tackling dummies and comparison of impacts in tackle and flag football, and (4) the Well-Integrated Screening and Evaluation for Women Across the Nation program, an initiative that provides cardiovascular screening and lifestyle programs to uninsured and underinsured women. Jones also leads Mathematica’s work with the Agency for Healthcare Research and Quality’s (AHRQ) Comparative Hospital System Performance (CHSP) Initiative to develop the Compendium of U.S. Health Systems and leverage the Compendium to study the formation of health systems and how they deliver care. Past work for AHRQ includes an analysis of the methods used to calculate the AHRQ quality indicators, with a focus on how the methods can be improved to better facilitate comparisons across types of hospitals.
Before joining Mathematica in 2008, Jones held positions at the University of North Carolina at Chapel Hill; Abt Associates, Inc.; and Duke University, where his research focused on issues related to preventive care for children. Jones holds a Ph.D. in economics from the University of North Carolina at Chapel Hill. He publishes in and serves as a reviewer for peer-reviewed journals.
Multi-City Evaluation of Sugar-Sweetened Beverage (SSB) Taxes
Understanding the Risks of Tackling in Youth Football
Using innovative mouth guard sensor technology, Mathematica is conducting a rigorous evaluation over 27 months to measure head impacts in more than 40 youth football teams.
Coordinating Center for Comparative Health System Performance
The Agency for Healthcare Research and Quality created the Comparative Health System Performance Initiative (1) to study how health care delivery systems promote evidence-based practices in delivering care and (2) to understand the connections between the dissemination of patient-centered outcomes research...
WISEWOMAN Evaluation and Technical Assistance
We are leading technical assistance and evaluation activities for this program that provides low-income, underinsured, and uninsured women ages 40 to 64 with health services to support prevention, management, and treatment of cardiovascular disease.
Evaluation Design for a Transformed Healthy Start Program
Mathematica developed an evaluation design and plan for the transformed Healthy Start Program, an initiative that aims to reduce racial and ethnic disparities in infant mortality. The data collection tools we developed included program surveys, a site visit protocol, and a focus group protocol.
Effects of Sweetened Beverage Taxes in Philadelphia and Oakland: Fewer Beverage Purchases, but Increased Cross-Border Shopping and Mixed Effects on Consumption
A Mathematica issue brief synthesizes new and recent evidence on how the two cities’ beverage taxes affected purchases, consumption, and the retail environment.
Study Documents Purchasing, Consumption Impacts of Philadelphia’s Sweetened Beverage Tax
New research reported in a National Bureau of Economic Research working paper finds that, after roughly one year, Philadelphia’s tax on sweetened beverages did not substantially reduce children’s consumption of such beverages overall.
