Current Research

Dr. Yi employs behavioral economic approaches to examine basic processes underlying addiction and related behaviors. His research focuses on valuation of delayed outcomes (delay discounting) and dynamic inconsistency as principal factors in substance use, abuse, and relapse. More recently, Dr. Yi’s research has explored intervention approaches to remediate accelerated delay discounting associated with addiction and other loss-of-control health behaviors. He is also broadly interested in the intersection of intertemporal and interpersonal decision-making.
