1) Is there an optimal length for an internal ferrite antenna?

Within limits, the bigger the better.

2) If so, then why don't all radios have one that size?

Not everyone wants to lug around a radio the size of a steamer trunk.

3) Is ferrite expensive or something?

Larger ferrite rods are considerably more expensive than smaller ones.
This was just a quick spot check, but one site was offering 2" ferrite
rods for $2, 7.5" for $12, and 12" for $75.

4) How can my little Degen 1102 (tiny ferrite antenna) do so well on MW
while my ATS505 does so poorly?

There could be any number of reasons. I know some of the other Sangeans
are purposely designed with a less than optimal antenna interface to
reduce overload problems in Europe where enormous transmitters are
fairly common. It could be simply that Degen put more effort into MW.
