Answer: d. the Japanese firm will sell steel at a higher price abroad than at home.
Explanation:
Price elasticity measures the change in quantity demanded resulting from a change in price. The higher the price elasticity, the more the change.
In this scenario, the price elasticity is lower abroad than it is in Japan. The company will therefore charge a higher price abroad because they know that the quantity demanded will not change as much even if they raise prices. This is as opposed to Japan where the quantity demanded will change more if they increase prices.
