# Macroeconomics and Microeconomics - Class 12 Economics

Chit-Chat Time

(After getting 1000 rupees, Raju is going with his friend, Sunny, to purchase some articles.)

Raju: Hello Sunny, how are you?

Sunny: I am fine, Raju. What about you?

Raju: I am also fine. My mom gave me 1000 rupees as a gift yesterday for my birthday.

Sunny: Oh, wow! That is great. So, have you planned where you are going to spend that money?

Â Raju: Yes, I have many options. I want to purchase novels, a puzzle cube, fancy bracelets, and a Parker pen (Beta gold ). Will you come with me for shopping?

Sunny: Sure! Letâ€™s go.

Raju: (At the Shop)

Uncle, please show me some interesting novels, Parker pens,

bracelets, and puzzle cubes.

(Shopkeeper showing Raju all the demanded items)

Sunny: Uncle, please tell me how much I have to pay for the items.

Shopkeeper: Your bill is of Rs. 1200.

(Raju is bargaining with the shopkeeper, and he finally pays 1000 rupees to the shopkeeper.)

Raju: Thank you for this discount!

(Raju is coming with his friend, Sunny, back home.)

Sunny: Have you ever wondered what amount will it be if we add all the demands by consumers in India?

Raju: Hmm. It will be a huge amount. I need to go now, see you tomorrow!

(Raju reaches home and has a conversation with his father.)

Father: Hello son, where are you coming from?

Raju: Today I went to the market to purchase some articles from the money I received on my birthday.

Father: Great! So, what did you buy?

Raju: A Parker pen, a bracelet, and two novels. The total cost of these items is Rs. 1000 after bargaining.

Father: Very nice!

Raju: If we add all the purchases (demand) made by the consumers and all the sales (supply) by the sellers in our country, it will be a huge amount. Does someone calculate that amount?

Father: Yes! When you purchased these things and that seller sold these things, this purchase and sale was made at an individualâ€™s level and an individual firmâ€™s level. This is a small (micro) level.

However, when we talk about purchases and sales made in the whole country, then that is at a big (macro) level.Â Our government collects and uses this data.

 Important Topics in Economics:

Let us understand

(1) Microeconomics and Macroeconomics

Economics is broadly divided into two parts. They are:

• Â  Â  Â  Microeconomics
• Â  Â  Â  Macroeconomics

(a) Microeconomics

Microeconomics is the study of the economic behaviour of individuals, households, and firms in decision making and allocation of resources.

Microeconomics is concerned with the following:

• Â  Â  Â  Supply and demand in individual markets (Example: Textile)
• Â  Â  Â  Individual consumer behaviour (Example: Consumer choice theory)
• Â  Â  Â  Individual producer behaviour
• Â  Â  Â  Individual labour markets (Example: Demand for labour wage determination in that individual market)

(b) Macroeconomics

Macroeconomics is the branch of economics that deals with the behaviour and performance of an economy as a whole.

It is generally the study of central issues like:

• Â  Â  Â  Employment
• Â  Â  Â  The growth rate of national output
• Â  Â  Â  GDP
• Â  Â  Â  Inflation
• Â  Â  Â  General price level and stability

(2) Vital components of microeconomics

Â Â  (a) Theory of consumer behaviour

This theory states that a rational consumer allocates his income for the purchase of different goods and services with the aim to maximise his satisfaction.

Â Â  (b) Theory of producer behaviour

This theory states that a rational producer has to decide what and how much to produce with the aim of profit maximisation.

Â Â  (c) Theory of price

This is the theory that tells us how prices are determined in the market.
