Rosalie Liccardo Pacula is a professor at the Pardee RAND Graduate School, where she has served on several dissertation committees. She previously served as director of RAND's BING Center for Health Economics and co-director of the RAND Drug Policy Research Center. Her research at RAND largely focused on issues related to illegal or imperfect markets (health care markets, insurance markets, illicit drug markets), measurement of the size of these markets, the impact they have on behavior (suppliers and consumers), and the effectiveness of policy interventions at targeting behavior within these markets. More recently her work has shifted to evaluating the impact of recent opioid policies in the US. She has explored the influence of buprenorphine diffusion, OxyContin reformulation, insurance expansion, medical marijuana and naloxone distribution laws on opioid related harm. She has also done work examining the size of the market for illicit opioids. Pacula has been a member of the National Bureau of Economic Research (NBER) since 1997, serves on the editorial board of several journals, and is a scientific reviewer for the National Institutes of Health's HSOD committee. She received her Ph.D. in economics from Duke University.
