Answer:
a. increase price in the short run but not in the long run.
Explanation:
The firms don't use resources that are available in limited quantities. So, as firm output increases, they can use resources in higher quantity but at the same price.
Therefore, as quantity demanded increases, the firms can supply higher quantity without any increase in resource cost. So, price increase in short run but not in the long term.
Tariffs can be helpful if the imports are unfairly cheaper than the domestic counterparts. This would level the playing field and help the domestic companies compete more effectively.
Tariffs can be harmful for consumers because there is strong possibility that the increased costs will raise consumer prices.
