The economy operates at an equilibrium level of real Gross Domestic Product (GDP). Full employment GDP represents the maximum sustainable output an economy can achieve without generating accelerating inflation.
An inflationary gap specifically occurs when the equilibrium level of real GDP exceeds the full employment level of GDP. This situation implies the economy is producing beyond its potential capacity, which typically leads to upward pressure on prices.
The income multiplier explains how an initial change in spending leads to a larger change in national income, rather than defining the relationship between equilibrium and full employment GDP. An automatic stabilizer refers to policy mechanisms (like progressive taxes) that automatically dampen economic fluctuations. Neither term describes the scenario where equilibrium GDP is above full employment GDP.
With respect to inflation in the Indian context, consider the following statements:
1. Retail inflation, measured by the Consumer Price Index (CPI), is the primary metric used by the Reserve Bank of India (RBI) for monetary policy formulation.
2. Core inflation includes volatile components like food and fuel prices, providing a more stable measure of underlying inflationary pressures.
3. Supply-side factors, such as monsoons affecting agricultural output and global crude oil prices, play a significant role in India's inflation dynamics.
4. Headline inflation refers to the total inflation in an economy, including volatile components such as food and energy prices.
Which of the above statements are correct?
