Understanding Economics and the Economy

Economics is one of the most important and useful subjects in understanding how individuals, businesses, and governments make decisions regarding the use of limited resources. From the price of a packet of milk to the working of banks and national budgets, economics plays a vital role in our daily lives. This chapter introduces the meaning, nature, and scope of economics, along with its major branches and activities.

What is Economics?

Economics is the social science that studies how people, societies, and governments make choices about using limited resources to satisfy their unlimited wants. It helps us understand how individuals earn, spend, and save money, how businesses operate, and how governments manage the country’s finances and resources.

• It examines how people earn income, how they spend it, and how they make choices between different alternatives.

In simple words,

Economics is the study of scarcity and choice.

Economics is about:–

• Scarcity (limited resources),
• Choice (selecting the best possible option), and
• Efficiency (making the best use of resources).

Economics tries to answer:–

• Why do we face problems like poverty or unemployment?
• Why are some countries rich while others are poor?
• How can a country grow its economy and improve living standards?

Economics as a Developing Social Science

Economics is called a developing social science because:–

• It deals with human behavior, which is complex and ever-changing.
• It is not based on fixed laws like natural sciences (e.g., physics), but on trends and generalizations.
• New theories are constantly being developed to understand changing economic conditions.

Economics uses observation, analysis, and reasoning to study economic activities and human behavior in society.

Economics: A Science of Wealth

The classical economist Adam Smith, known as the “Father of Economics,” defined economics as a science of wealth.
In his famous book “An Inquiry into the Nature and Causes of the Wealth of Nations” (1776), he wrote:

“Economics is an inquiry into the nature and causes of the wealth of nations.”

According to Smith:

• The focus of economics should be on increasing the wealth of a nation.
• Wealth means material goods and services that have value.
• Economics should study how wealth is produced and distributed.

Economics According to Alfred Marshall

The British economist Alfred Marshall gave a broader view. According to him:

“Economics is a study of mankind in the ordinary business of life.”

He believed that:

• Economics is not just about wealth but also about human welfare.
• It studies how a person earns income and how he uses it to satisfy needs.
• Economics is a part of social science, closely connected with human behavior and choices.

Thus, economics is both the study of wealth and the study of human beings.

Economics as the Science of Human Behavior

Modern economists like Lionel Robbins gave a more precise definition:

“Economics is the science which studies human behaviour as a relationship between ends and scarce means which have alternative uses.”

This definition emphasizes:

• Ends = Unlimited human wants or goals.
• Means = Limited resources like land, labour, capital.
• Alternative Uses = Each resource can be used in multiple ways, so a choice must be made.

Thus, economics studies how we make decisions when resources are scarce and can be used in different ways.

Economics has a dual nature—it is both a science and an art.

(1) Economics as a Science

• Economics is considered a science because it studies cause-and-effect relationships and follows a systematic method of investigation.
• It uses data, observation, and logical reasoning to form theories and laws.

Characteristics of Economics as Science:

• Observation of facts
• Hypothesis and testing
• Theory formation
• Prediction of outcomes

Examples:

• When price increases, demand usually falls.
• If the cost of production rises, supply may decrease.

Thus, economics helps to explain and predict human behavior in economic terms.

(2) Economics as an Art

• Economics is also an art because it involves practical application of knowledge.
• It teaches us how to make better economic decisions—whether it’s budgeting, investing, or saving.

Economics as an Art Involves:

• Skill in choosing the best alternative
• Practical application of theory
• Finding solutions to real-life problems

Example:

• A businessman uses economic principles to maximize profit.
• A consumer uses it to maximize satisfaction within a limited budget.

Hence, economics is both a science that explains and an art that guides.

An economy refers to the system in which people in a country or region produce, distribute, and consume goods and services.

Every economy performs three basic functions:

1. Production – Creating goods and services using resources.
2. Distribution – Supplying goods and services to where they are needed.
3. Consumption – Using goods and services to satisfy human needs.

For example, in the Indian economy, farmers grow crops (production), traders and transporters distribute them (distribution), and people buy and use them (consumption).

So, the economy includes all economic activities that help fulfill human wants and improve the standard of living.

Economic Activities

Economic activities are the actions people take to earn a living and satisfy their needs and wants. These include:–

• Farming, fishing, and mining
• Manufacturing and construction
• Providing services like education, healthcare, banking, etc.

● These activities involve the production, exchange, and consumption of goods and services.

● Economic activities involve use of resources (land, labour, capital, and entrepreneurship) and are always directed toward the production and exchange of goods and services.

● People perform economic activities to fulfill their infinite needs, and these activities form the basis of economic study.

For example:

• A farmer growing wheat
• A teacher providing education
• A shopkeeper selling goods

All these are economic activities because they involve earning income or generating value.

Economic Problems

The biggest economic problem is that resources are limited, but human wants are unlimited.

For example, we may want better housing, education, health, transport, and entertainment—but there is only so much land, money, and labour available.

So, we must choose how best to use these resources. This leads to economic problems, which are common to all economies.

Economic activities are grouped into three major sectors:

1. Primary Sector – Activities that involve using natural resources.

• Examples: agriculture, fishing, forestry, mining.
• This sector is the backbone of developing economies like India.

2. Secondary Sector – Activities that involve manufacturing and processing.

• Examples: textile factories, steel plants, food processing.
• This sector converts raw materials from the primary sector into finished goods.

3. Tertiary Sector – Activities that provide services.

• Examples: banking, transportation, education, healthcare.
• This sector supports the primary and secondary sectors and plays a growing role in modern economies.

Based on ownership and decision-making, economies can be classified into three types:

Capitalist Economy:

• Private individuals own the means of production.
• Decisions about production and pricing are made by the market (demand and supply).
• Example: United States.

Socialist Economy:

• The government owns and controls the means of production.
• It plans and decides what to produce, how to produce, and for whom.
• Example: North Korea (historically the USSR).

Mixed Economy:

• Both the private sector and the government participate in economic activities.
• It combines the benefits of capitalism and socialism.
• Example: India is a mixed economy.

Every economy, whether rich or poor, must solve three central problems because of scarcity of resources and unlimited wants.

1. Limited Resources and Unlimited Wants

Resources like land, water, minerals, capital, and labour are scarce—they exist in limited quantities.

However, human wants are endless—people always want more and better goods and services. This mismatch creates a problem of choice.

Hence, we must decide:

• Which wants to satisfy first?
• How to use resources most efficiently?

2. Basic Economic Questions

To solve the problem of scarcity, every economy must answer the following three fundamental questions:

(i) What to Produce and How Much to Produce?

• A society must choose which goods it will produce (essential goods like food and clothes, or luxury goods like cars and phones).
• It must also decide how much to produce based on needs and available resources.

For example, should a country invest more in hospitals or defense?

(ii) How to Produce?

• This involves deciding the method of production:–

1. Labour-intensive methods use more human labour (common in developing countries).
2. Capital-intensive methods use more machines and technology.

The choice depends on the country’s resources, technology, and employment needs.

(iii) For Whom to Produce?

• This question is about distribution:–

1. Who gets how much of the produced goods?
2. Will the goods be equally available to all, or only to the rich?

This is linked to the distribution of income and wealth in the society. A fair distribution ensures social justice and welfare.

Economics is divided into five major branches based on types of activities. These are:

1. Consumption

• It refers to the use of goods and services by individuals or households to satisfy their needs.
• Example: Eating food, wearing clothes, using a mobile phone.

2. Production

• It refers to the creation of goods and services using inputs like labour, land, and capital.
• Example: A factory producing shoes, a farmer growing rice.

3. Exchange

• It means the buying and selling of goods and services, often using money as a medium.
• Example: Buying vegetables in a market, online shopping.

4. Distribution

• It deals with how the income or wealth generated from production is shared among different people.
• Example: Wages for workers, rent for landowners, profits for entrepreneurs.

5. Revenue

• It is the income generated from selling goods or services.
• Example: A shopkeeper earns ₹10,000 in a week from sales.

The sum total of all economic activities forms the core of economics as a subject.

Economics is a vital social science that helps us understand how people and societies use limited resources to meet unlimited wants. It is not only about wealth and production but also about choices, welfare, and human behavior. By studying economic activities such as consumption, production, exchange, distribution, and revenue, we can better understand how the economy functions. As both a science and an art, economics offers both theoretical knowledge and practical tools to improve our daily lives and decision-making.
