The paper “Community Rating and Distortions of Relative Prices in Insurance Menus” investigates the distortionary effects of community rating on relative prices in insurance markets with multiple products. We show that common community-rating approaches may generate counterintuitive distortions in the price differentials between plan options that run in the opposite direction as the distortions in overall price levels. We document that partial age-based community rating leads to this pattern in private health insurance exchanges in the U.S. The distortions are large enough that older individuals often face and sometimes choose dominated options. We discuss the potential effects of alternative menu-based approaches to community rating that would reduce relative price distortions.
