Answer:
The correct answer is C. The U.S. economy could experience unsustainable? expansion, resulting in a sharp economic downturn.
Explanation:
Unsustainable economic growth is a theoretical economic situation proposed by Jagdish Bhagwati in 1958, where economic growth can become so counterproductive as to leave a country in worse conditions than before.
If growth is based solely on exports, these could lead to a fall in the terms of trade of the exporting nation. In rare circumstances, this fall could be even greater than the gains generated by the growth, worsening the country's situation. This result is viable only if the growing country influences international market prices.
