Presentation by Beth Kilbreth (Univeristy of Southern Maine, Muskie School of Public Service) at AcademyHealth's 2011 Annual Research Meeting.  Dr. Kilbreth discusses the results of a SHARE-sponsored study evaluating risk selection in public health plans in Massachusetts, Maine, and Vermont.  Dr. Kilbreth explores: (1) whether state-sponsored public plans targeting low-income uninsured workers experience adverse selection; (2) to what extent enrollment risk in these programs is affected by enrollee cost sharing; and (3) how out-of-pocket cost sharing affects utilization among low- and moderate- income public plan enrollees.  The presentation concludes with a discussion of the policy implications of the study findings.Presentation by Beth Kilbreth (Univeristy of Southern Maine, Muskie School of Public Service) at AcademyHealth's 2011 Annual Research Meeting.  Dr. Kilbreth discusses the results of a SHARE-sponsored study evaluating risk selection in public health plans in Massachusetts, Maine, and Vermont.  Dr. Kilbreth explores: (1) whether state-sponsored public plans targeting low-income uninsured workers experience adverse selection; (2) to what extent enrollment risk in these programs is affected by enrollee cost sharing; and (3) how out-of-pocket cost sharing affects utilization among low- and moderate- income public plan enrollees.  The presentation concludes with a discussion of the policy implications of the study findings.
