Yes, those are the "simple" straightforward MA's.
Now, suppose the following.
In a pension scheme they have a rule for increasing allowances of retirees
by
either the indices of prices on the one hand or the indices of wages on
the
other. It is further stipulated that the highest of either at any moment
(1st of
January, or in practice every 1st October of each year in order to be able
to
have it effected in January) is applied, one an another in any 10-yearly
period
as from each individual retiree's maturity date in the scheme.
Here, it's really flouri****ng-time for APL, because of the geometric MA's.
(Since e.g. every quarter of a year participants may get retired, you need
to
keep track of two times four different indices per year. Plus you have to
take
in account the numerous tem****ary provisions to avoid hardness caused by
changing the rules.
Why do they make the rules so complicated? Pensionfund Boards don't care
about
complexity, they only *****s and decide what they think is justice for the
participants - and it can even be more complicated,. The actuary & the
(APL-)programmer do the "work" after).
