Which of the following assumptions about long-term care (LTC) policies in the 1980s and 1990s were proven incorrect?

The assumption regarding the need for higher-than-expected margins for adverse selection is considered incorrect based on the experiences in the LTC insurance market during the 1980s and 1990s. At that time, insurers underestimated the impact of adverse selection, which occurs when those who are most likely to need the insurance are the ones most inclined to purchase it. This led to financial strains on many long-term care policies, as carriers did not initially recognize the need for higher margins to accommodate this selection bias.

Carriers often found that they had not set sufficient reserves or premiums to manage the higher-than-anticipated claims resulting from adverse selection. Therefore, the assertion that higher margins were needed proved to be inaccurate, as the actual financial experience revealed a far more significant risk of adverse selection than they had accounted for.

In contrast, the other assumptions about morbidity experience and lapse rates were more aligned with the actual outcomes observed in the market of that era. Morbidity rates were indeed higher than expected, leading to a greater number of claims, and lapse rates, which reflect how many policyholders let their coverage expire, were also lower than anticipated, meaning that more people held onto their policies longer than originally forecasted. This confirms that the correct choice highlights a critical misconception
