Dr. Anh Ngo, PhD
Dr. Ngo earned her PhD in Economics from the University of Illinois at Chicago in August 2018. Her research interests focus on tobacco control policies and alcohol taxes. Applying innovative research designs, Dr. Ngo and her colleagues examined the impacts of tobacco control policies (i.e. point of sale advertising bans, graphic warning labels, MPOWER) on smoking prevalence and cigarette consumption in a global context. Her research has been published in leading public health journals such as Addiction, Preventive Medicine, and International Journal of Research and Public Health.
Currently, Dr. Ngo is extending her research to e-cigarettes and alcohol taxes. Specifically, using online discrete choice experiments, she and her colleagues are examining the impacts of flavors, device types, and health warning messages on the choice of e-cigarettes among US young adults. In the other projects, using time-series data of alcoholic beverage prices and taxes from Organization for Economic Cooperation and Development (OECD) countries, she and her co-authors estimate the excise tax pass through rates to prices of alcohol products to provide evidence on factors associated with alcohol tax avoidance and evasion in both US and international contexts.
