Macro Aggregates & Economic Policies: Fiscal and Monetary Tools Explained
What are Macro Aggregates?
Macro aggregates are big-picture economic indicators that reflect the health of an economy. These help governments and economists understand trends and take action.
Key Macro Aggregates:
-
National Income (GDP, GNP)
-
Employment Level
-
Price Level (Inflation/Deflation)
-
Investment and Savings
-
Balance of Payments (Exports & Imports)
π Interrelationships between Macro Aggregates
These aggregates are interconnected. A change in one affects others.
π Example:
-
If employment increases, β people earn more β demand increases β production rises β GDP increases.
π Another Example:
-
If inflation rises, β purchasing power drops β demand may fall β production slows β employment may decrease.
π° Tools of Economic Policy
Governments use two main tools to manage these macro aggregates:
ποΈ 1. Fiscal Policy
Fiscal Policy = Governmentβs income and spending policy
Main Tools:
-
Government Expenditure β spending on infrastructure, salaries, etc.
-
Taxation β collecting money from individuals/businesses
β Goal: Control inflation, reduce unemployment, and promote economic growth.
Expansionary Fiscal Policy:
-
Used during recession
-
Govt increases spending or cuts taxes to boost demand
Contractionary Fiscal Policy:
-
Used during inflation
-
Govt reduces spending or increases taxes to lower demand
π¦ 2. Monetary Policy
Monetary Policy = Central Bankβs control over money supply & interest rates
β Goal: Control inflation, maintain currency stability, ensure economic growth
Tools of Monetary Policy:
-
Repo Rate (Rate at which banks borrow from RBI)
-
Reverse Repo Rate
-
Cash Reserve Ratio (CRR)
-
Statutory Liquidity Ratio (SLR)
-
Open Market Operations (buying/selling govt securities)
Expansionary Monetary Policy:
-
Lowers interest rates β more borrowing β more spending/investment β boosts economy
Contractionary Monetary Policy:
-
Raises interest rates β reduces money supply β controls inflation
π Interrelationship Between Fiscal and Monetary Policy
-
Both policies work together to stabilize the economy.
-
Fiscal policy is decided by government; monetary policy by central bank (RBI in India).
-
Sometimes they can support each other, or be in conflict if not coordinated well.
