Many insurance carriers enjoy a robust business. As an example,
UnitedHealth Group Incorporated,
headquartered in Minnesota, had about $185 million in sales in 2017
and employed approximately
230,000 people. Still, as an industry report from the business
research company Hoovers established,
insurers of all stripes, health or auto or property or anything
else, face two major hurdles. First, they “are
increasingly subject to a large number of regulations and reporting
requirements by states.
Consequently, some insurers have withdrawn from states that impose
burdensome requirements.”
Second, large-scale “claims have become more common, creating
problematic concentrations of risk for
individual insurers. . . . And some risks can be large enough to
drive insurers out of business or cause
them to curtail services offered, increase rates, or leave states
where risk is highest.”26 Thus, profits can
be high within the industry, but so can payouts in the aftermath of
major catastrophes. The report goes
on to say that “floods, hurricanes, and tornadoes” produce the
riskiest economic circumstances for the
industry. Consequently, states in which these weather events are
more common—Alabama, Florida, and
North Carolina—have seen some carriers cease business operations
within them.27
• In selecting coverage and setting prices, how does an insurance company choose the ethical balance between making a reasonable profit and risking catastrophic losses of its own?
• Should the law require that carriers offer property insurance
in states where harsh natural disasters
occur? Or should federal and state monies be used to subsidize
insurance companies’ resources in
these circumstances? In each case, why or why not?
