General idea: we shorten risk adjustment transfers by an amount x
x is obtained by solving the following equation
(condition: let risk adjustment payments only rise by (1 ∆)௧
=ݔܥ̅ (1 ∆)௧ሾ1 − (1 ݀)௧ሿ − ܥ̅ሾ 1 ∆ ௧ −
1 ∆ ௧ሿ+ܥ̅ሾ 1 ∆ ௧ 1 ݀ ௧ − 1 ∆ ௧ሿ
Solution
15. The stabilization method is compatible with
additional (constant) RA reductions

If ߩ is an undefined factor <1 to reduce risk adjustment payments
for young adults, it can be shown that the following equation holds
We now project RA-transfers into the future
-without any changes (status quo)
-with stabilization
-with stabilization & additional reduction

17. Conclusion
(1) Young adults aged 19-25 years are among the most affected by
rising RA transfers in aging societies.
(2) Refusal to pay health insurance premiums more prevalent
among young insured (not shown). Acts of protest?
(3) Rather than demographic change, different health utilization
patterns of young and old is the main driver for expansion of
risk adjustment transfers.
(4) A reduction of RA payments made by young adults may be
appropriate, which could eliminate inefficiencies (e.g. premium
subsidies).
