Shigeoka specializes in applied microeconomics with concentrated focus on health economics, employing advanced statistical methodologies across administrative datasets, national surveys, and controlled laboratory experiments. His research portfolio examines critical policy questions including healthcare pricing effects on patient behavior, physician incentive structures, health insurance expansion consequences, and pandemic interventions like mask mandates and vaccine requirements. He also investigates broader socioeconomic phenomena such as prohibition policy impacts on mortality, educational reform effects, and AI-driven productivity shifts in labor markets.

His publication record reveals consistent output in top economics venues, with recent work demonstrating methodological rigor in causal inference through quasi-experimental designs. Key thematic clusters include health policy evaluation (accounting for 43% of recent output), labor market dynamics (29%), and education economics (14%), reflecting interdisciplinary engagement with public health, political economy, and technological disruption.
