4. Answer the following:
Question 1.
Explain various factors of production.
Answer:
Production means the creation of utility.
There are four factors of production. They are land, labour, capital, and entrepreneur.
They are explained as follows:
(i) Land: In economics, the land is a wider concept. It is the primary, natural and original factor of production. According to Prof. Marshall, land means all natural resources, available on, above, and below the surface of the earth.
E.g. On the surface of the earth – mountains, rivers, forests, etc.
Above the surface of the earth – air, sunshine, etc.
Below the surface of the earth – gold, silver, coal, etc.
E.g. A landlord gets rent for the productive use of land.
(ii) Labour: Labour is a living factor of production. It is the most active and human factor of production. Any physical or mental effort undergone during the production process to earn a reward is called labour. The remuneration of labour is wages. E.g. a labourer working in a factory.
(iii) Capital: Capital refers to produced means of production. It is the stock of capital assets that yield income. Capital earns interest for its productive use. Capital is a man-made factor of production.
E.g. machinery, raw material, etc.
(iv) Entrepreneur: The entrepreneur is the organizer and the controller of a business. He combines all the factors of production. He supervises the production process. He is a special kind of labourer who gets rewarded in the form of profit. An entrepreneur is regarded as a real captain of the industry.
Question 2.
Write a note on Kautilya’s views on Economics.
Answer:
Kautilya was traditionally known as ‘Chanakya’ or ‘Vishnugupta’. He is identified as the pioneer in the field of Political Science and Economics in India.
He was a teacher, philosopher, economist, and royal advisor of the Mourya Empire.
He wrote the ancient Indian Political treatise named “Arthashastra”, where Artha’ means ‘Wealth’ and ‘Shastra’ means ‘Science’. It covers various aspects of the political, social, economic, and military organization of the past economy.
Key-points based on Kautilya’s views are as follows:
- The role of the State or Government is crucial. The state should regulate economic activities.
- He focused on creating wealth as a means, to ensure the welfare of the state.
- He stated a great need for efficient administrative machinery for good governance.
- Compilation of Political ideas into Arthashastra.
- Kautilya attached great significance to public finance.
Question 3.
Explain ‘Trade Cycle’ in economics.
Answer:
The Trade cycle is also called the ‘business cycle’. It takes place due to fluctuations in business.
There are ups and downs in overall economic activities. These fluctuations arise due to inflation and depression.
It can be explained with the help of the following diagram.
Inflation means a continuous rise in the general price. Depression is a continuous fall in overall prices and lowering down economic activities in general.
In the given diagram, the ‘X’-axis indicates the time period and the ‘Y’-axis shows the level of economic activity. Line ab shows a steady growth path.
Various phases of the business cycle or trade cycle like Prosperity, Recession, Depression, Recovery, and Inflation indicate fluctuations in economic activities.
When unemployment is created due to the trade cycle (cyclical fluctuation), it is called cyclical unemployment. It is temporary in nature.
5. State with reasons whether you agree or disagree with the following statements:
Question 1.
Profit is a contractual income.
Answer:
No, I do not agree with the statement.
- Contractual income is that income that is paid as per the terms and conditions of payment.
- Profit is not a contractual income.
- It is residual income because profit is the earning of an entrepreneur.
- It is the income that is left over after making payments to all factors of production.
- Profit may not be always positive.
- It can be zero or even negative.
- Thus, it is a fluctuating income.
Question 2.
The concepts of economic development and economic growth are interrelated but not the same.
Answer:
Yes, I agree with the statement.
- Economic development and economic growth go hand in hand. They are interrelated but they do not mean the same.
- Economic growth refers to an increase in a country’s real output of goods and services, whereas economic development refers to the progressive changes in the socio-economic structure of a country.
- Also, economic growth considers the quantitative aspect whereas economic development considers the qualitative aspect.
- Again, economic growth is possible without economic development but, economic development is not possible without economic growth.
- Hence, economic development is a wider term and economic growth is a part of it which makes them two different concepts.
Question 3.
An entrepreneur plays an important role in the economic development of a country.
Answer:
Yes, I agree with the statement.
- In the history of developed countries, it has been shown that entrepreneurs have played a very important role in economic development. Hence quality entrepreneurship is a crucial indicator of economic development.
- Economic development requires a class of talented entrepreneurs because they are the ones who keep the wheels of the economy moving.
- An entrepreneur is a person who has the ability to recognize business opportunities.
- He is a person with some special qualities such as the ability to innovate, do hard work, have the vision, risk-taking capacity, social responsibility, positive thinking, etc.
Question 4.
There is no difference between individual wants and collective wants.
Answer:
No, I do not agree with the statement.
- Individual wants refer to those wants which are satisfied at the individual level. While collective wants are those wants that are satisfied at the general level or macro level.
- A doctor using a stethoscope is an example of individual wants while people travelling by train or bus is an example of collective want.
- Thus, there is a difference between individual wants and collective wants.
Question 5.
Microeconomic and macroeconomic are two different phenomena.
Answer:
Yes, I agree with the statement.
- Microeconomics deals with the economic behaviour of small units while macroeconomics deals with the economic behaviour of large units.
- Microeconomics uses the slicing method while macroeconomics uses the lumping method.
- Microeconomics is based on partial equilibrium analysis, while macroeconomics is based on general equilibrium analysis.
- The microeconomic analysis is also called a “Price theory” while macroeconomic analysis is also called an “Income theory”.
- Thus, microeconomics and macroeconomics are two different phenomena.
