Dr. Riha Vaidya

Dr. Riha Vaidya (Ph.D. Economics, University of North Carolina at Chapel Hill) is an economist with expertise in health economics and applied microeconomics. She is trained in economic modeling and advanced econometric techniques such as program evaluation methods and panel data econometrics. She also has extensive experience in analyzing administrative data, and individual- and household-level survey datasets.

While at IMPAQ, Dr. Vaidya has served as task lead, health policy researcher, and program evaluation expert across several projects. Her work focuses on the evaluation of the Community-based Care Transitions Program (CCTP), a pilot program from the Center for Medicare and Medicaid Innovation (CMMI). As a part of the CCTP evaluation, her responsibilities include developing comparison groups, formulating regression models, and analyzing Medicare claims data to evaluate the impact of care transition models on readmissions and medical care expenditures of high-risk Medicare beneficiaries. Dr. Vaidya has also conducted research on health policy issues related to the Affordable Care Act under IMPAQ’s CCIIO health insurance marketplace analytic support contract. For the CCIIO contract, Dr. Vaidya has been responsible for leading initiatives to assess the policy landscape related to out-of-network emergency care payments, and to conduct a post-certification assessment of qualified health plans’ inclusion of specialists in their provider networks.

Dr. Vaidya’s previous work was in the area of global population health with a focus on analyzing the determinants of individual health behaviors and outcomes. In particular, she used a household panel survey dataset from China to assess the influence of the prices of various goods and services on individuals’ choices of health behaviors such as smoking and exercising, along with analyzing the impact of those behaviors on health outcomes.

In addition to her research in health economics and policy, Dr. Vaidya also has research interests and experience in education policy. While at the University of North Carolina, Dr. Vaidya was part of a research team assessing the impact of exposure to public school accountability policies on student outcomes such as grade retention and high school completion.
