Steven R. Hursh mainly investigates Behavioral economics, Consumption, Demand curve, Unit price and Pharmacology. Steven R. Hursh has included themes like Conceptual framework, Public economics and Substance abuse in his Behavioral economics study. His work deals with themes such as Social psychology, Reinforcement and Econometrics, which intersect with Demand curve.

His study in Reinforcement is interdisciplinary in nature, drawing from both Mathematical economics, Choice rule and Operations research. His work focuses on many connections between Unit price and other disciplines, such as Psychiatry, that overlap with his field of interest in Hydromorphone, Emergency medicine and Buprenorphine. His study in the field of Drug, Fentanyl and Onset of action also crosses realms of Remifentanil.
