hmmm...intitially the prices would no doubt rise (if they couldn't absorb the cost) becasue of the lost investment in that other country. The higher prices of the products would have to offset that lost investment, factories, training, inventory storage, etc. On the other hand, if the corporation had enough money they could absorb the cost of the loss. I'm sure that could happen too.
Eventually the higher prices would probably come down after their products sold created revenues that overcame the lost investment. Unless of course they are pricks and like to make even more money. But the buyer would have to have confidence in them actually lowering the prices or they would flop. (But how do, if you are a corporation, tell the public "We are going to rasie the price of X but don't worry, because in two years we will lower them, and by the way 'We are proud to announce that we are made in America.'") I don't think people would buy it.

(pun intended)
