I thought Turtledove's Worldwar series handled some of these ideas well -- the aliens invading Earth knew it would take centuries to get here, but they assumed nothing would be different when they arrived because that's how history played out on all the planets they knew about. (If he covered the economics of it with more than a handwave, I'm not recalling it now...)
