Describe the four major sectors in an economy according to the macroeconomic point of view.
The four major sectors of an economy according to the macroeconomic point of view are:
1. Households
2. Firms
3. Government
4. External Sector
Below are the one by one explanations.
1. Households
Households buy goods and services for consumption and also supply factors of production like land, labour, capital, and entrepreneur. Households provide the market for the output of the firms.
2. Firms
Firms are economic units that carry out the production. They employ and organise factors of production and undertake the production process for the motive of profit making.
3. Government
A state/government provides law and order, maintains growth and stability and provides administrative services. The main motive of a government is to undertake developmental projects such as dams, roads, heavy industries that usually have long gestation periods. The government invests in education, health sector and provides these services at nominal price. The motive of a government is to serve and not to make profits.
4. External Sector
This sector is engaged in export and import (external trade) of goods and services. If domestically produced goods and services are sold to the rest of the world, then it is called export. If the goods and services are purchased from the rest of the world, then it is called import.
What is marginal propensity to consume? How is it related to marginal propensity to save?
Explain why public goods must be provided by the government.

What is a barter system? What are its drawbacks?
What is the difference between ex ante investment and ex post investment?
Distinguish between revenue expenditure and capital expenditure.
What are official reserve transactions? Explain their importance in the balance of payments.
Why should the aggregate final expenditure of an economy be equal to the aggregate factor payments? Explain.
What are the main functions of money? How does money overcome the shortcomings of a barter system?
What is marginal propensity to consume? How is it related to marginal propensity to save?
Suppose marginal propensity to consume is 0.75 and there is a 20 per cent proportional income tax. Find the change in equilibrium income for the following (a) Government purchases increase by 20 (b) Transfers decrease by 20.
Explain the automatic mechanism by which BoP equilibrium was achieved under the gold standard.
Explain why the tax multiplier is smaller in absolute value than the government expenditure multiplier.
Why should the aggregate final expenditure of an economy be equal to the aggregate factor payments? Explain.
Why is the open economy autonomous expenditure multiplier smaller than the closed economy one?
Explain why public goods must be provided by the government.
Differentiate between devaluation and depreciation.
Would the central bank need to intervene in a managed floating system? Explain why.
Suppose that for a particular economy, investment is equal to 200, government purchases are 150, net taxes (that is lump-sum taxes minus transfers) is 100 and consumption is given by C = 100 + 0.75Y (a) What is the level of equilibrium income? (b) Calculate the value of the government expenditure multiplier and the tax multiplier. (c) If government expenditure increases by 200, find the change in equilibrium income.
