Economist: At the insistence of the International Monetary Fund, India slashed import duties from an average of 90 percent in 1991 to 30 percent in 1997. Many feared that the result would be a devastating drop in Indian manufacturing due to competition with imported goods, but the doomsayers were wrong. Manufacturing output increased by 50 percent in that time. The increase was due to the decrease in duties, since, with the decrease, imports of goods used in manufacturing were much higher than imports of consumer goods.
Which of the following, if true, would most strengthen the economist’s argument?The economist needs support for the causal jump from “duties fell and imports of manufacturing inputs rose” to
“that is why manufacturing output rose.” The best strengthener ties the higher input imports to a concrete improvement in manufacturers’ ability to produce more.
A. A significant portion of manufacturers in India continued to produce goods from the same raw materials as before 1997 but at much lower cost.
Yes. Lower production cost is exactly what you would expect if cheaper or more available imported inputs followed the duty cuts, and lower cost makes it easier to expand output. This directly supports the economist’s proposed mechanism.
B. Manufacturing increased significantly worldwide after 1992.
No. This suggests a global tailwind that could explain India’s increase without relying on the duty cuts, so it does not strengthen the specific causal claim.
C. Production of goods and services in India was significantly enhanced by an increase in telecommunication infrastructure in the 1990s.
No. This is a plausible alternative cause of higher output, which makes the economist’s “it was the duty cuts” explanation less compelling.
D. Economic growth did not increase everywhere in India in the 1990s and 2000s.
No. Regional unevenness does not help show that lower duties caused the nationwide manufacturing increase.
E. Much of the increase in manufacturing output was of goods for export.
No. Export growth describes where the output went, but it does not connect that growth to cheaper manufacturing inputs from lower duties, which is the economist’s key link.
