SSC Selection Post 2025 PYQ — Question 16

Correct Answer

Consumer Price Index (CPI)

Explanation

The Consumer Price Index (CPI) is a critical macroeconomic indicator used to track changes in the price level of a specific basket of goods and services typically purchased by urban households. It measures inflation or deflation by comparing the total cost of this representative basket at a given time to a predetermined base year, reflecting changes in the cost of living for average consumers.

The remaining choices refer to completely different economic concepts. Gross Domestic Product (GDP) quantifies the total market value of all finished goods and services produced within a country's borders during a specific timeframe. The Gini Coefficient is a statistical metric used to gauge income inequality or wealth distribution within a population. The Balance of Payments is a comprehensive statement tracking all financial and economic transactions between residents of a country and the rest of the world over a defined period.

Key Points

The CPI serves as one of the primary tools for central banks, like the Reserve Bank of India or the Federal Reserve, to formulate monetary policies and make adjustments to benchmark interest rates.

The basket of goods and services monitored by the CPI generally includes daily essentials such as food, clothing, housing, transportation, medical care, and education.

A rising CPI signals price inflation, meaning the purchasing power of the domestic currency is decreasing because consumers must spend more money to buy the exact same volume of goods and services.

Governments frequently utilize CPI data to adjust income tax structures and calculate cost-of-living adjustments (COLA) for social security benefits, pensions, and public wages to prevent inflation from eroding real income.

Additional Facts

While the CPI calculates inflation from the perspective of the end consumer, the Wholesale Price Index (WPI) tracks price changes at the factory gate or wholesale level before items reach the retail market.

The specific items included in the CPI basket, along with their assigned weights, are periodically updated by national statistical agencies to accurately reflect evolving consumer spending habits and lifestyle shifts.

Important Questions and Answers

Question: What is the primary difference between the Consumer Price Index (CPI) and the Wholesale Price Index (WPI)?

Answer: The CPI measures the average change over time in the prices paid by ultimate retail consumers for goods and services, whereas the WPI tracks price movements at the wholesale or producer level, focusing entirely on goods traded between businesses.

Question: How does a continuous, sharp increase in the Consumer Price Index affect the overall purchasing power of a nation's currency?

Answer: A continuous increase in the CPI indicates rising inflation, which directly reduces the purchasing power of the currency, meaning each unit of money buys a smaller quantity of goods and services than it did previously.
