Study Notes
Introduction
- Macroeconomics is a study of the whole economy, examining its overall health
- It differs from microeconomics, which focuses on individual markets
- Macroeconomics considers factors like prices, employment, and economic growth across the whole economy

Basic Concepts: Economics deals with factors like natural resources, labor, and capital to generate economic wealth
-
Flow of Production: Goods and services are produced and transformed through productive processes
-
Final Goods: Goods not used as inputs in further production
-
Capital Goods: Durable goods used in future production
-
Intermediate Goods: Goods used as inputs in another production process
-
Consumption Goods: Goods purchased for direct consumption.
-
Capital Goods: Goods used in a production process.
-
Methods:
- Product Method: Calculates the total value of all final goods and services produced in an economy
- Expenditure Method: Calculates aggregate expenditure on final goods and services
- Income Method: Calculates the income received by all factors of production
Money and Banking

Functions of Money:
- Medium of Exchange: Facilitates the exchange of goods and services
- Unit of Account: Provides a common way to measure and compare different goods and services (in monetary values)
- Store of Value: Holds purchasing power over time.
-
Demand for Money:

- Speculative Motive: Holds money in anticipation of future opportunities (e.g., buying assets when interest rates are low)
-
Supply of Money:
- Currency: Notes and coins issued by the central bank (e.g., RBI in India)
- Deposits: Balances in checking/savings accounts held at banks
- High-Powered Money (also called Monetary Base): Currency in circulation + reserves held by commercial banks
- Instruments of Monetary Policy: Tools used by central banks (e.g., RBI in India) to manage the money supply

- Ex ante: Planned or expected values of variables (e.g., consumption or investment) in a given period.
- Ex post: Actual values of variables in a given period
-
Autonomous Expenditure and the Multiplier:
- Autonomous Expenditure: Expenditures that are independent of the level of income
- Multiplier: The magnified effect of an autonomous expenditure change on the equilibrium level of income.
The Government: Functions and Scope
-
Functions of Government:
- Allocation: Providing public goods (e.g., national defense) as they are not provided efficiently by the private sector, due to free-rider problem
- Distribution: Ensuring distributive justice in the economy, through taxation, spending and transfers to households
- Stabilization: Regulating the economy through fiscal policy to manage fluctuations like unemployment and inflation
-
Components of Government Budget:
- Revenue Account: Current government income and expenditure
- Capital Account: Government capital income and expenditure
Open Economy Macroeconomics
- Open vs. Closed Economy: In an open economy, there are transactions with other countries (imports and exports)
- Balance of Payments: Records transactions between a country and rest of the world
-
Exchange Rates: The price of one currency in terms of another
- Flexible Exchange Rates: Determined by supply and demand within the foreign exchange market
- Fixed Exchange Rates: Governed by monetary authorities, a country pegs a currency to another stable currency or a commodity, like gold.
- Trade Deficits and Surpluses: Trade deficit (imports > exports) and Trade surplus (exports > imports)
- Saving-Investment Identity: Saving= Investment + Net Exports in an open economy
