Would you say the firm is price discriminating? Why or why not, and if yes what type of price discrimination is this? If people began trading these hard drives freely between the US & Mexico, what would happen to the price? (Add the two demand functions together to get a combined demand function for both countries. You will get 2y = ... & then continue from there.) Would total surplus be higher or lower than when the hard drives were not being traded across the border, and why?
