What does adverse selection in benefits enrollment typically refer to?

Adverse selection in benefits enrollment refers to the tendency of certain employees to enroll in specific benefits more than others, usually based on their risk characteristics or health status. This phenomenon can occur when employees who are more likely to need certain benefits (such as those with higher health risks opting for more comprehensive health insurance) choose these over other options, while those who may not anticipate needing those benefits may opt out.

This selection process can lead to an imbalance in the pool of enrollees for specific benefits, causing higher costs for the provider of those benefits. For example, if a health plan is primarily selected by individuals who are likely to require more medical care, the insurer will face higher claims. This can affect the sustainability of the benefits program and is a critical consideration in benefits design and management.

The other options do not capture the core principle of adverse selection accurately. While age-related choices and familiarity with benefits can influence selections, they do not necessarily highlight the risk-based nature of adverse selection. Additionally, opting for the most costly benefits describes decision-making based on cost, not the concentrated enrollment driven by risk factors among certain employee subsets.
