A new study to be published in the INFORMS journal Marketing Science has revealed that health insurance has a small effect on brand enrollments, raising the question of whether health insurance television advertising is worth the expense.
The study to be published in the September edition of the INFORMS journal Marketing Science is titled “Advertising in Health Insurance Markets,” and is authored by Bradley T. Shapiro of the University of Chicago.
Shapiro’s research has indicated that industry regulators have long been concerned that the effect of television advertising by health insurers would serve to “cream skim,” or attract an advantageous risk pool, and to use certain deceptive claims to take advantage of the elderly. But what his research found was that since television advertising does not have a significant impact on brand enrollments, those concerns may not be as valid.
Shapiro found that there is no statistically meaningful relationship between advertising effectiveness and the average health risk. However, advertising was found to be more effective on populations with lower average income, and those populations often have worse health in ways that are difficult to capture with health risk scores. These two pieces of evidence combined suggest that the regulator fear of advertising-induced cream-skimming is not supported by data.
He added that his research also focused on whether it is imperative for health insurers to advertise just to compete, focusing on the effects on one health insurance firm when it decided to unilaterally cease television advertising.
“The estimates suggest that no material loss of brand share occurred,” said Shapiro. “This provides evidence against the assumption that health insurers must advertise to preserve or gain market share.
Shapiro found that while television advertising may not be the most effective way for health insurers to generate increase enrollments, it may serve more general societal, informative benefits, such as letting consumers know of open enrollment deadlines, and helping consumers choose plans that better reflect their own preferences.
