Investigators from Stanford University Target Economics (Exogenous Exits, Market Structure, and Equilibrium Contracts In Health Care): Economics

2026 JAN 21 (NewsRx) -- By a News Reporter-Staff News Editor at Insurance Daily News -- Investigators publish new report on Economics. According to news reporting originating from Stanford, California, by NewsRx editors, the research stated, “This paper quantifies the causal effects of exogenous health insurer exits on contract structure and health care market outcomes, proposing market concentration as a likely mechanism for these effects.”

Our news editors obtained a quote from the research from Stanford University, “Leveraging the termination of the largest health insurer in Colombia, I find that the use of fee-for-service contracts increased after the termination relative to capitation contracts. Treatment effects are larger in markets with higher provider than insurer concentration at baseline.”

According to the news editors, the research concluded: “Results suggest that equilibrium contracts place the financial risk on insurers in markets where providers have higher bargaining leverage.”

This research has been peer-reviewed.
