Research Interests

Dr. Liu conducts research and teaching in public policy and management, with an overarching focus on public sector innovation for economic development and community building. Drawing on her expertise in statistics and economics, she uses quasi-experimental and experimental methods to study how state and local governments learn, adopt, evaluate, and terminate policies that support these goals. Her work also incorporates advanced network analysis and spatial econometric models to understand how executive leadership fosters innovation and policy learning across U.S. governments. In addition, she investigates how governments enhance efficiency and responsiveness during natural disasters—such as hurricanes and floods—and public health crises like the COVID-19 pandemic, further highlighting her commitment to improving policy effectiveness in times of crisis.

This study examines the impact of reductions in Indiana's corporate income tax rate beginning in July 2012. It employs the synthetic control method to construct a counterfactual, or “synthetic Indiana,” using quarterly manufacturing employment data from 23 states that did not change their tax rates during the 2003–2018 study period.
