The purpose of this contribution is to investigate why private insuran
ce of the risk of long-term care (LTC) has known little market success
in major industrialized countries, even among the relatively well-to-
do. Using a principal-agent framework, it shows that the purchase of L
TC insurance by the parent (the principal) is likely to diminish the a
mount of LTC provided by the major caregivers; namely children earning
a comparatively low wage in the labor market. Anticipating this moral
hazard effect, the parent is predicted to renounce the purchase of LT
C coverage in many cases. This finding throws serious doubts on the we
lfare effects of recent moves to introduce compulsory social LTC insur
ance, as, for example, in Germany.
