Over at healthinsurance.org, I've noted them: 1) more "active renewals" than expected; 2) relatively low churn; and 3) a high level of takeup for Cost Sharing Reduction (CSR) subsidies -- that is, silver plan selection by buyers with incomes under 200% of the Federal Poverty Level. My takeaway:
Many healthcare professionals and scholars worry that a market providing choice from a large selection of private health plans with a complex array of features and coverage rules offers too much complexity for typical buyers, most of whom are on the lower end of the income scale.
