Question

GDP Deflator is used to measure:

• A. Unemployment rate
• B. Inflation in the economy
• C. Poverty ratio
• D. Fiscal deficit

Hint:

Unlike the Consumer Price Index (CPI), which only tracks a "basket" of consumer goods, the GDP Deflator is broader because it includes everything produced in the country (including capital goods and government services).

Answer 1

The Correct Option is B

Step 1: Understanding the Concept:
The GDP Deflator, also known as the Implicit Price Deflator, is a comprehensive economic metric used to identify the level of price changes for all new, domestically produced, final goods and services within an economy. Unlike the Consumer Price Index (CPI), which tracks the cost of a fixed "basket" of goods and services typically purchased by urban consumers, the GDP Deflator is much broader in scope. It reflects the prices of all components of GDP, including consumption, investment, government spending, and net exports. Because it accounts for every item produced within the country's borders, it provides a more holistic view of inflation than other indices that focus only on specific sectors like retail or wholesale prices.
Step 2: Key Formula or Approach:
To calculate the GDP Deflator, one must understand the relationship between Nominal GDP and Real GDP. The formula is expressed as:
\[ \text{GDP Deflator} = \left( \frac{\text{Nominal GDP}}{\text{Real GDP}} \right) \times 100 \]
Here, Nominal GDP is the value of production at current market prices, meaning it includes the effect of inflation. Real GDP is the value of production at constant base-year prices, which isolates the actual change in the volume of production by removing the impact of price fluctuations.
Step 3: Detailed Explanation:
The primary utility of the GDP Deflator lies in its ability to separate "real" economic growth from "nominal" growth. When an economy reports a $10%$ increase in Nominal GDP, it is unclear if this is because the country produced $10%$ more goods or if prices simply rose by $10%$. By using a base year as a benchmark, the Real GDP tells us what the output would have been worth if prices hadn't changed. The ratio between these two figures reveals the extent of price inflation.
For example, if the Nominal GDP is $\$110$ billion and the Real GDP is $\$100$ billion, the Deflator is $110$. This indicates that the general price level has risen by $10%$ since the base year.
Comparing it to other measures:
1. Unemployment Rate (Option A): This measures the percentage of the labor force that is jobless and actively seeking work, unrelated to the price index of goods.
2. Poverty Ratio (Option C): This is a social indicator measuring the proportion of the population falling below the poverty line, based on income or consumption levels.
3. Fiscal Deficit (Option D): This is a budgetary metric representing the excess of total government expenditure over total receipts (excluding borrowings).
The GDP Deflator is unique because it is not based on a fixed basket of goods; its components change automatically based on what is being produced in the economy at any given time, making it a Paasche price index.
Step 4: Final Answer:
Therefore, the GDP Deflator is specifically designed to act as a tool for measuring inflation and the purchasing power of money by comparing current output values with base-year values.
