Important Macro Economics Concepts For Your Interviews

 

2 Approaches to calculating GDP

Consumption Approach: GDP = H.H. Consumption + Investment + Govt. Expenditure + Net Exports

Income Approach: GDP = Wages + Interest + Rent + Profit + Tax + Depreciation

Out of the two, the consumption approach is preferred as the expenditure can be traced easily. This approach is used in India.

Per Capita Income

It is the average annual income of an individual expressed in dollars. It indicates the average income of an individual in a country or state.

Formula = GDP/Population

In Macroeconomics, we also try and classify the types of market-based on the competition level and nature. Let us look at the various categories -

Types of Market

1. Perfect Competition

A hypothetical market where no single producer or consumer has the market power to influence the prices.

Characteristics

A large number of buyers and sellers

Goods are perfect substitutes of each other

All buyers and sellers have perfect, complete and homogenous market information

There are no entry and exit barriers

2. Oligopoly

A market with a small number of sellers selling a similar commodity.

Characteristics

High interaction among sellers

Sellers are price makers

3. Monopoly

A market with a single seller with no close substitute for the product either due to technical reasons or licensing.

Characteristics

Seller is the price maker

The firm can enjoy abnormal profit

Fierce competitiveness of an existing firm

To influence the economy of a nation, we have two tools known as the monetary and fiscal policy.

Monetary Policy	Fiscal Policy
The government’s policy of achieving economic objective (employment, per capita income, the balance of trade, economic parity) through money supply.   Contraction policy: deflation or decrease in prices Incremental policy: inflation or increase in prices	The government’s policy of achieving economic objective (employment, per capita income, the balance of trade, economic parity) through government revenue collection and spending.   Fund sources: Taxes, duties, fines, borrowings Fund uses: Infrastructure, mining, public welfare, defence, power generation, R&D

In addition to these, here is a list of other important terms related to Macroeconomics.

Other Important Terms:

1. Goods and Services Tax: Consumption based tax levied on the manufacture, consumption and sale of goods and services at a national level. It is an example of indirect tax.

2. Inflation: It is the quantitative measure of the rate at which the average price level of a basket of selected goods and services in an economy rises over a period of time.

3. Deflation: Gradual decrease in the prices of goods and services typically a result of the contraction in the economy.

4. Recession: A period of temporary economic decline in trade identified by a fall in the GDP for consecutive quarter. It is a result of business cycle contraction in an economy.

5. Stagflation: Condition of slow economic growth and relatively high unemployment accompanied by rising prices.

6. Depreciation: Gradual decrease in the economic value of a capital, stock or firm.

7. Devaluation: Deliberate downward adjustment of the value of a country’s currency relative to the baseline.

8. Unemployment: It is the condition that arises when one is willing to work but cannot find any work at an economically productive age for a consecutive period of atleast 6 months.

9. Fiscal Policy: It is the means by which a government adjusts its spending level and the tax rates to monitor and influence a nation’s economy.

10. Balance of trade: This occurs when the total imports and the total exports of a country is equal. A positive balance of trade occurs when the exports are more than imports, whereas a negative balance of trade occurs when the imports are greater than exports.
