48. Which statement about the GDP deflator is true?
Answer: A
Its percent change from one year to the next is the inflation rate.
The GDP deflator measures the change in prices of all new, domestically produced, final goods and services in an economy. Its percent change from one year to the next reflects the inflation rate, making this statement accurate.
A) Its percent change from one year to the next is the inflation rate.
This statement is correct because the GDP deflator is calculated by comparing the current year's GDP to the GDP from a previous year, adjusted for price changes. Therefore, the change in the GDP deflator directly indicates the inflation rate for the economy.
B) It includes fewer core economic measurements than the typical GDP.
This statement is incorrect. The GDP deflator encompasses all final goods and services produced domestically, similar to the comprehensive nature of GDP itself. It does not include fewer measurements but rather reflects a broader scope of price changes.
C) It is a more reliable indicator of economic well-being than real GDP.
This statement is misleading. While the GDP deflator provides valuable information about inflation, real GDP is a critical measure of economic well-being as it accounts for inflation and reflects the true output of an economy. Therefore, real GDP is often considered a more direct indicator of economic health.
D) It follows a nearly strict decreasing pattern starting from a given base year.
This statement is incorrect. The GDP deflator does not necessarily follow a strictly decreasing pattern; it fluctuates based on the economic conditions, inflation rates, and various other factors. Therefore, this statement misrepresents the nature of the GDP deflator's behavior over time.
Conclusion
The statement that the percent change of the GDP deflator from one year to the next is the inflation rate is definitively correct, as it accurately describes the function of the GDP deflator in measuring price changes. All other options fail to accurately represent the characteristics or implications of the GDP deflator, emphasizing the importance of understanding its role in economic analysis.
