Behavioral Economics and Insurance Exchanges

A recent commentary (NEJM 2015; 372: 695-98) explains how information provided on healthcare exchanges influences choices on coverage and what types of modifications could help improve these decisions.

Current plans are categorized as Bronze, Silver and Gold based on monthly premiums and out-of-pocket expenses (Related link: Understanding Plans on Healthcare.gov).  Gold plans are characterized by higher monthly premiums and lower out-of-pocket expenses.  However, the authors sampled a group of people.  They found that plans that are labeled as “gold” were preferred by the majority whether the plans had higher monthly premiums and lower out-of-pocket expenses or the reverse (low monthly premiums and higher out-of-pocket expenses).  Rather than using “gold,'” “silver,” or “bronze,” their recommendation would be to provide more practical information by providing estimates of annual costs with best-case and worst-case scenarios.

On many exchanges, the plans are listed by order of lowest monthly premiums to highest monthly premiums.  “When people make choices, they often settle for options at the top of a menu…for example, all else being equal, politicians listed at the top of ballots receive more votes than those whose names appear lower on the list.” Also, using monthly premium differences rather than weekly premium differences also influences choices. Thus, even the innocuous design of a website, could adversely influence the selection of the best plan for a given participant.

Bottomline: If the affordable care act and health exchanges are not eliminated, improving the presentation of information could help many participants get the health coverage that actually meets their needs.
