Final answer:
The consumer price index will increase, but the GDP deflator will not increase.
Step-by-step explanation:
If the price of Italian shoes imported into the United States increases, the correct answer is option b. The consumer price index will increase, but the GDP deflator will not increase.
The consumer price index (CPI) measures the average change over time in the prices paid by urban consumers for a market basket of consumer goods and services. Since Italian shoes are a consumer good, an increase in their price would be reflected in the CPI.
On the other hand, the GDP deflator is a measure of the overall price level of all final goods and services produced within an economy. It takes into account the prices of goods and services produced by both consumers and businesses. Since the price increase of Italian shoes only affects consumer goods and not the overall production of goods and services, the GDP deflator would not increase.
