The correct option is 2 only
Explanation
Macroeconomics distinguishes itself from microeconomics through the method of aggregation. While microeconomics analyzes individual markets and agents, macroeconomics combines these individual variables to study the economy as a whole. This involves aggregating all goods and services into a single composite output and all individual prices into a general price level.
Statement-wise Analysis
- Statement 1 is Incorrect: Macroeconomics simplifies the analysis of the economy by aggregating all goods and services produced into a single "representative good." This theoretical simplification allows economists to study aggregate demand and aggregate supply without getting lost in the complexities of millions of individual markets.
- Statement 2 is Correct: The price of this representative good corresponds directly to the general price level of the economy. It is not unrelated; rather, it serves as the aggregate measure of prices (e.g., Consumer Price Index or GDP Deflator) used to monitor inflation and the cost of living.
- Statement 3 is Incorrect: Aggregation inherently involves a loss of detail. By treating all output as a single good, macroeconomics abstracts away from the distinctive characteristics of individual sectors. It does not capture specific differences, such as the biological nature of agricultural production versus the mechanical nature of industrial production. These distinctions are the subject matter of microeconomics.
Key Takeaway
Aggregation allows macroeconomics to focus on economy-wide variables like total output (GDP) and the general price level, but it does so by intentionally overlooking the specific characteristics and distinctions of individual goods and markets.
