1.1 Definition of economics: Adam Smith, Alfred Marshall, Robbins

Origin and Meaning of Economics

The word economics is derived into English language from the Greek word "Oeconomicus" by Xenophon in 431 B.C. which is a Socratic dialogue principally about household management. So, economics means managing household worth limited resources i.e. indome. The history of economics is an old as the history of mankind. The start of economics traced back to Plato and Aristotle.

Plato gave his economic ideas in his book, "The Republic" and Aristotle in "Politics and Ethics". According to Aristotle, economics is the science of household management and an art of wealth getting and wealth spending.

Economics is a social science. Economics was treated as a part of political science, ethics and religion until 18th century. The classical economists developed it as a separate social science in 18th Century. Thus, economics is a science in the sense that the economists

aim to develop theories of human behaviour and to test them against the facts.

What is economics?

Trying to define economics is difficult because no one can agree on a single definition. Throughout history, famous economists, from Adam Smith, one of the first to study economics, to modern thinkers, have given their own ideas about what economics is all about. Adam Smith, who is known as the "father of economics," saw it as the study of how and why a country gets rich.

Alfred Marshall, a famous economist of the 20th century, said that economics is the study of how people act in everyday life, especially when it comes to getting and using things that are necessary for their well-being. Robbins, another pioneer economist, gave a more precise definition. He said that economics is the scientific study of how people decide how to use limited resources to achieve different objectives.

P.A. Samuelson added to the conversation by saying that economics is the study of how people and society decide to use limited resources to make things and services and distribute them to different people and groups. There are various definitions of "economics" in the literature, but none of them are universal.

Having said that, having a general idea of what economics is can help you understand its smaller parts, like microeconomics.

Economics as a Social Science

As a social science, economics looks into how people spend their money and the problems they face in society. At its root, economic behaviour is about economising, which means that people try to get the most out of the limited resources they have, like time, money, labour, and space.

The basic study of how people divide their limited resources among competing needs to make goods and services, in order to meet their endless wants and get the most benefits, comes from this desire to maximise gains. To put it more simply, economics is the study of how people and groups use their resources in the best way possible.

The reasons for this behaviour of saving money come from some basic economic facts about existence. To begin, people's wants and desires are unlimited and are always growing as their living standards, comfort, and knowledge improve. Second, the means that can be used to meet these needs are limited and insufficient.

These resources include natural resources like land, human resources like labour and skills, man-made resources like technology and tools, and the drive to be an entrepreneur that makes resource use possible. There is also an economic value for time and knowledge. But there are only so many of these resources that are available. This is called resource deficit, and it forms the centre of many economic problems.

People always have to make choices because their natural tendency is to get the most out of things. This is necessary because we know that not all wants are equally important or pressing, and resources can be used in different ways that give different results. So, people need to think about the pros and cons of each choice in order to make the best choice.

As a social science, economics looks at how people and groups make these decisions so they can reach their economic goals, provide goods and services that people want, and use resources effectively. Economics sheds light on the complicated ways people make choices about how to distribute resources by looking at different options and trying to find the best ones. Economics doesn't have a clear, agreed upon definition.

This lack of clarity comes from the fact that the field has changed over time, growing in size, scope, and difficulty since Adam Smith founded it. The lines between different areas of economics are still indistinct and hard to define. Some economists say that the field of economics is still very young and has a lot of uncharted territory to find.

According to Charles Schultz, "Economics is still a very young science, and many problems in it are almost untouched." In the same way, Zeuthen said that economics is an "unfinished science." Milton Friedman, a Nobel laureate in economics, stressed how important economics is for understanding how people act and make choices when resources are limited.

He quotes, "The existence of scarcity is the starting point for economics." Another Nobel Prize winner, Friedrich Hayek, talked about how prices and decentralised decision-making help keep all the different people in an economy working together. He said that the market process itself is a discovery process that is always changing based on new information and tastes.

In the same way, John Maynard Keynes stressed how important aggregate demand and government policies are in shaping economic results, especially when the economy is unstable. Despite this, economics is proud to be the oldest and most fully formed of the social sciences, even though it is still growing. Its continued growth in both scope and intellectual depth shows how important and relevant it will always be.

In short, economics looks at how people save money and what happens as a result. It also finds the links between different economic events and gives us the tools to understand them better. Finally, it predicts how economic decisions will turn out. Because it uses a methodical and organised technique, economics deserves to be called a social science.

The fields of economics are always changing and growing, but they will always be one of the oldest and most developed social sciences, with fields that are always getting deeper and broader.

1.1 Definition of Economics

According to Jacob Vainer

"Economics is what economists do".

This covered and extension area of economics depends upon economists. Thus there is no universal acceptable definition of Economics. As we know society are changeable, so definition of economics are also changed.

According to Barbara Wotton

"Whenever six economists are gathered

there are seven opinions"

Though, the great economist are:

Adam Smith

Alfred Marshall

Lionel Robbins

They have given the definition of economics, as follows:

Adam Smith Definition of economics: Wealth definition

Adam Smith (1723-1790), a citizen of Scotland, is popularly known as the father of economics as well as the leader of classical economists. Adam Smith was the first economist to present a systematic analysis of economics. Therefore, he is regarded as the "Father of Economics." Adam Smith published his epoch-making book "An Inquiry into the Nature and Causes of Wealth of Nation" in 1776 AD.

This book is popularly known as wealth of nation. It is considered as the Bible of the Science of Economics. From 1776 to 1850, several great economists, such as J.B. Say, David Ricardo, T.R. Malthus, J.S. Mill, etc., had fully supported and followed the economic ideas of Adam Smith. They were of the view that economics is concerned with production, consumption, exchange and distribution of wealth.

Hence, according to classical economists Adam Smith, economic is too subject that studies about wealth. Wealth is base of human happiness. Every person should think how to accumulate wealth. If has following feature/characteristics / components.

Characteristics of Wealth Definition

1). Study of Wealth

According to the wealth definition,

economists is concerned only with the

study of wealth. It deals with the

production, consumption, exchange and

distribution of wealth. Economics studies

the human beings who are engaged in

the production and consumption of wealth

and does not study those human beings

who are not engaged in production of mat-

erial things.

2) Main goal of human-being is to earn wealth

As per the wealth definition, the main goal of human being is to earn money because wealth or money is only one month which can satisfy the human wants. "By hook and cook," we have to work and accumulate wealth. Human wants are fulfilled by wealth. If we have no wealth, our existence is zero in our society.

3) Primary place to wealth

This definition gives primary focus to wealth

and the secondary emphasis to human beings.

This shows that the classical economists have regarded man as a means and wealth as an end. Hence, without wealth, no any human activities are possible. By the help of wealth, human wants are fulfilled.

Therefore, this definition has given first priority to wealth and second priority to Human beings.

4) Employed labour is the source of wealth

Adam Smith's definition of economics assumed that wages earned by active human resource is the only one and most important source of income of a country. He also suggests that the active laborers can earn high amount of wages only through division of labour in production and distribution of goods and services.

5) Study of economic man

Wealth definition has imagined the study of such a man who always thinks about earning more and more wealth throughout his life. Thus, Adam Smith explains that economics studies the behaviour of those human beings who have main objective of

earning more and more wealth. Human

being of such nature is an "Economic

Man".

He always things about earning more and more wealth.

He involves in production of wealth.

He has no concern with human qualities, like, love, affection, honesty, beauty, co-operation etc.

Critics / Weakness of Adam Smith definition of Economics

The wealth definition of economics has been criticized on several grounds by different economists like Caryle, Ruskin, Markiew and Morris etc. They have characterized it as a bastard Science, Dismal Science, Bread & Butter Science, and Gospel of Mammon. Neo-Classical economist Alfred Marshal has criticised this definition on following grounds.

i) Too much emphasis on wealth

Adam Smith considered that economics is the science that deals only with wealth and materials goods. But the critics pointed out that economics

studies not only materials goods. and wealth but also some non-material things such as service of a teacher, a lawyer, an engineer which also fulfill human needs and wants. Therefore, services produced by human resources also constitute important aspects of wealth.

ii) Incomplete definition (Ignorance of hot issues of society)

The wealth definition is incomplete. It lacks analytical approach. It does not shed any light on the nature of economic problems like unemployment, inequality, poverty, scarcity, corruption etc. It emphasises on learning and spending of wealth but ignores the scarcity and choice involved in the production and distribution of wealth.

ii). Wrong assumption of single source of wealth.

According to wealth definition, the source of wealth of a nation is only employed labour. But critics viewed that human resources, capital resources, physical resources, rents, interest and profits are also used as sources of wealth. All these resource can be put together and utilized to earn maximum wealth by a nation.

iv) Wrong assumption of economic man

Adam Smith's definition only included those

persons who involved in economic activities

in the study of economics. But all the

persons who live in the world they should

involve not only in earning wealth but also

obtaining minimum satisfaction from the

utilization of their wealth. Except wealth,

there are other qualitative aspects in human

life like friendship, love, cooperation, respect,

self-esteem, sympathy which enrich human

being more than wealth. Thus, the pure eco-

nomic man as explained by Adam Smith

can't exist in the real world.

V. Wrong assumption of primary place to wealth

According to wealth definition of economic wealth is given primary place and human beings is given secondary place. But critics argue that man should be given first priority and wealth should be given second priority it is because all types of wealth are used by human being according to his/her objectives.

Alfred Marshall Definition of Economics (Welfare Definition)

Alfred Marshall a popular neo-classical British economist developed the new definition of economics which is known as welfare definition. Marshall was the founder and leader of neoclassical school of economics. He had published a well-known book entitled "Principles of Economics" in 1890 AD.

According to his opinion, "Economics is, on the one side, a study of wealth, and on the other and more important side, a part of the study of man." Marshall has given more emphasis on human health in his definition. Many economists such as A.C. Pegou, Edwin Cannah, and W.H. Beveridge have supported the Marshall's view.

According to Marshall economics is the science of study of materials things. Every materials thing provide satisfaction the welfare to human being I mankind.

If has following features / Characteristics

1) Study of material welfare

According to Marshall definition, economics studies only those activities of a common man, who is concerned with the promotion of economic welfare. Marshall claimed that any form of goods or services of economic value

that fulfils human desires and needs comes within the subject matter of economics. Marshall puts emphasis on the enhancement of material welfare by consumption of material goods.

2) Study of ordinary human-beings

Welfare definition of economics has given

the main priority to the study of ordinary human-being rather than economic man of wealth definition. According to Marshall, ordinary human beings are those who get involved not only in accumulation of wealth but also try to experience love, sympathy, goodwill, respect, honor to make their social life more meaningful.

It means economics studies about the rational man and ignores the activities of irrational man like Shadhu or Sanyasi in Hindu religion (an isolated person).

3) Primary concern to man

According to Marshall, economics is the study of mankind in relation to wealth. He explains how a man in the ordinary business of life earns wealth and utilizes his/her income to achieve maximum satisfaction. He further adds that wealth is mad for the benefit of human beings but human being is not for wealth.

also suggests that primary importance should be given to human being and the secondary importance to wealth. Because all the wealths are mobilized by the hands of human beings.

4) Economics as a social science

According to Marshall, economics is a social science. It studies the economic problems of those individuals who live in an organized society. Man like Robinson Crusoe living outside the human society does not fall under the study for economics. Therefore economics does not study isolated person like monks, saints, beggars etc. because they are unknown about social problems and they are not rational human beings.

5) Normative Science Economics

According to welfare definition, economics is a Normative science since it studies what ought to be done to promote the material welfare of man and what should not be done. Similarly, it must be the job of an economist to provide the valuable judgement over the economic phenomena rather than to express the fact only.

Thus, normative economics explains what should be and what

Should not be. According to this definition, material things should be consumed to get maximum satisfaction then welfare is achieved.

Criticisms / Weakness of welfare definition of Economics

The welfare definition was accepted as a correct definition until the arrival of modern economist-Lionel Robbins. Welfare definition of economics has only focused on material things. It has not explained about services that give maximum satisfaction and welfare to human beings. It has following criticisms:

i) Classificatory definition

Marshall classified human activities into material and non-material welfare, economic and non-economic goods but he could not distinguish between these terms clearly. This definition is same as wealth definition of economics.

ii) Narrow definition of Economics

Marshall includes only material things within the study of economics and excludes all non-material things. But, there

are so many non-material activities that come under the subject matter of economics, which fulfill human wants and needs. For example, the service of human being such as teaching of teachers, treatment of doctors, service of engineers, advocacy of lawyers are non-material in nature because they work not only for earning wealth but also for fulfilling social needs.

The services in some cases would relate to ethical and social values. Therefore, this definition has narrowed the scope of economics.

iii) Welfare cannot be quantitatively measured

According to welfare definition, money has been taken as an instrument for the measurement of welfare. Though money may be a rough measure of welfare, it cannot be a satisfactory measure.

If is because the poor land rich per-

sons derive different level of satisfaction

from equal amount of money. The concept

of welfare is psychological phenomenon too.

If varies from individual. Therefore, it

is unscientific to define economics in terms

of welfare.

(iv) Connection between satisfaction and

Welfare is wrong

According to Welfare definition of

economics, every material thing provide satisfaction to human being then welfare is occurred. But according to critics, every material things may give satisfaction but no welfare to human beings. They may be harmful to human beings such as wins, cigarettes, drugs, alcohols etc. therefore connection between satisfaction and welfare in economic is wrong.

v). Pure social science

According to welfare definition, economic is a pure social science. It means that economics does not study the men living outside society. But, this is not true because even an isolated man such as Robinson Crusoe is subject to laws of economics such as labor of diminishing marginal utility, law of equity-marginal utility etc. Hence, economics should be taken more as a human science than a social science.

The isolated person have also human qualities so economic should study about them.

Lionel Robbins Definition of Economics (Scarcity Definition)

Lionel Robbins (1898 - 1984), a modern British economist who gave the most scientific and logical definition of economics in his famous book entitled, "An Essay on the Nature and Significance of Economic Sciences" published in 1932. He criticized the weakness of welfare definition given by Marshall and developed a new definition of economics.

In his view, economics is concerned with the problems arising from scarcity. His definition was supported by various economists such as Samuelson, Oskar Lange, Stigler, A. P. Lemer and so on.

According to Robbins, "Economics is the science which studies human behavior as a relationship between ends and scarce means which have alternative uses."

He argued that, human wants are unlimited but resources are limited.

Due to scarcity of resources, every economic problems are emerged. [1932]

Characteristics of Scarcity Definition

The main characteristics of scarcity definition given by Robbins are as follows:

i). Unlimited ends on wants

The human wants are unlimited. If one want is satisfied, another want appears in mind of man. Hence, it is difficult to satisfy all these wants at the same time. The man has to choose between more urgent and less urgent wants. Therefore human wants can never be fulfilled during one's lifetime.

ii). Limited Resources

The resources to satisfy the unlimited wants are limited for scarce. The economic problems arise due to the scarcity of resources. The resources are scared in relation to their demand. Here, scarcity is used in relative sense. If resources (means) are available in abundance like air, the economic problems will not arise.

Alternative uses of Resources

Lionel Robbins defined economics as

alternative uses of resources. Human

wants and necessities are different.

Human beings have different objectives.

According to their objectives resources are

used so that maximum satisfaction will

be occurred. For eg: If we have

limited money, we use that money for

buying books or purchasing clothes.

(iv) The wants are of varying importance. All wants or ends are not of the same importance. They differ in urgency. Some wants are more urgent than the other ones. More urgent wants are satisfied first, postponing the less urgent wants for a late date due to stability of resources. Hence, economics is sometimes referred to as a science of choice.

v) Rational human being

Modern economist Lionel Robbins assumed

human being is national because he/she gets maximum satisfaction from the consumption of material things. According to human being's money, he/she consumes goods and services. There is no chance of waste of goods.

Human being makes choice among the wants best on resources.

Criticisms of Scarcity Definition or Criticisms |

Weakness of Robbins definition of Economics

Scarcity definition is still a popular definition.

Despite its wider acceptability and applicability

in modern society, it has been criticized by

various economists like Barbara Woodton, William

Beveridge and Fraser on the different grounds.

This definition has not explained how

issues of the society like poverty, unemployment,

inequality etc. It has following weakness criticisms:

i) Ignorance of hot issues of society

According to critics, Robbins was unable to address the burning issues of modern economy such as unemployment, poverty, inequality, economic growth, trade cycle etc. They argued that the modern definition of economics must analyze macroeconomic issues in a scientific way.

Old wine in new bottle

Robbins definition of economics is considered as modern definition of economics. But according to critics this definition has no any new matters then Adam Smith and Marshall's definition of economics. For example, This definition has use resources instead of wealth, wants, instead of material things etc. It shows that this definition has carried the matter of previous definitions of economics. Thus, it

is just called, old wine in new bottle.

iii) Pure science

Critics are of the view that economics is not only a positive or pure science but also a normative science. It is the responsibility of an economist to offer any suggestion to solve a particular economic problem. Robbins' critics point out that if economics as a social science fails to contribute to human welfare, it is meaningless. There is no use of studying social science if it fails to promote human welfare.

Therefore, economies should study about what should be. So economics is not positive science, it is normative science.

(i) Even abundance may create economic problems:

According to scarcity definition of economics,

every economic problems are emerged due to

scarcity of resources. But according to critics,

sufficient or abundance of economic activities

also create economic problem. For example

abundance of labour supply, heavy rainfall

create the problems in society. Similarly

over production create the problem in society.

v). Wrong assumption of rational human beings

Scarcity definition of economic assumed

rational human beings for the utilization

of resources in economy. But according

to critics there is hardly found rational

human being in society. Due to various

circumstances human being becomes irrational

and he/she doesn't get maximum satisfaction

from the consumption of wants in

society.

Superiority of Robbins' Definition

Scarcity definition of economics given by

Robbins is claimed to be superior to

the Marshall's definition of economics on

the following grounds:

Scientific definition

Definition of economics given by is considered

to be more scientific and analytical than Marshall's

definition because it is far from classification.

Marshall's definition is classificatory into material

and non-material welfare, economic and non-

economic activities.

ii) Universal application

The concept of scarcity and choice is widely applied in any type of economic system. It is applicable to planned and unplanned economics, capitalist and socialist economics or mixed economics. Therefore, the concept of scarcity and choice is universally applicable in all types of economic system.

iii). Science of choice

According to Robbins, economics is science of choice. It is the major focus of this definition. Choice is the essence of economic problems. This is the realistic situation since means are always limited in relation to ends. An individual has to choose to derive maximum satisfaction from the limited income. It guides a government to utilize limited resources to meet infinite needs of the people.

Similarly, Robbins' definition guides entrepreneurs to achieve maximum output.

(iv). Wider scope

Robbin's definition of economics has wider scope than that of Marshall because Robbins says that all types of human wants, whether material or non-material come within the study of economics. Similarly, wants of any individual, whether living in society or not come within the study of economics. On the contrary, Marshall's definition includes only the material aspect and persons living only in society.

Comparison between Marshall's and Robbins' Definition

According to Marshall, economics is a science of material welfare whereas in the view of Robbins, economics is a science of choice. The two definitions have certain similarities and dissimilarities which are discussed below.

Similarities

i) Primary place to man

Both the definitions have given the primary place to man. In the video of Marshall, economics studies the mankind in terms of wealth whereas according to Robbins, economics studies the human behavior as a relationship between ends and scarce means which have alternative uses. Both definitions have common objectives as to study the mankind.

ii) Maximum welfare

Both the definitions have the concept of maximum welfare directly or indirectly. Welfare definition aims to utilize wealth to achieve minimum material welfare and scarcity definition aims to utilize scarce resources to achieve minimum satisfaction.

iii). Wealth and scores means

Marshall has used the word 'wealth' whereas Robbins has used the word 'scare means' in addition to wealth. But the meaning of both words is the same, only the presentation is different.

Dissimilarities

i). Economic and non-economic activities

Marshall classifies the human activities into

economic and non-economic. Economic activities

are related to physical goods which increase

material welfare. According to him, economics only

studies the material welfare whereas in Robbin's

words, all the human activities are under the

study of economics where scarcity and choice

arise.

ii). Social and human science

According to Marshall, economics is a social science which studies ordinary business of life. It does not study the extraordinary man like Robinson Cruseo. But, in the view of Robbins, economics is a human science which studies all the human beings who involve in the use of scarce means to fulfill the unlimited wants.

iii). Normative and positive science

Marshall regards economics as a normative science. Thus, the economists have the responsibility of making value judgment; their function is to examine the right or wrong of an economic activity. On the other hand, Robbins regards economic as a positive science. Thus, the economists have no responsibility of value judgment i.e. their task is not to examine the right or wrong of an economic.

activity. Their responsibility is to explain and explore but not to suggest.

iv) Classifications and analytical definition

Marshall classifies the human activities into economic and non-economic, and welfare into materials and nonmaterial. But Robbins' definition is based on subject of economic analysis.

v). Applicable in different economics

Marshall's definition is applicable only in capitalist economy where individual freedom is entertained but Robbins's definition is applicable in all types of economies such as socialist, capitalist and mixed economic system.

P.A. Samuelson's Definition of Economics

Introduction to P.A. Samuelson

Paul Anthony Samuelson was an American economist and the first American to win the Nobel Memorial Prize in Economic Sciences in 1970. Samuelson is one of the most influential economists of the 20th century and is known for his contributions to modern economic theory. He wrote the book “Foundations of Economic Analysis,” which helped establish economics as a mathematical and analytical discipline.

P.A Samuelson’s Growth definition (Modern Definition) of Economics

P.A Samuelson’s Growth definition of Economics is a modern definition of economics that focuses on studying economic growth and development.

According to Samuelson, “economics studies how people and societies allocate scarce resources to satisfy unlimited wants and needs over time.” The central theme of his definition is the importance of economic growth, which he believes is the key to solving many of the world’s problems.

Samuelson’s definition emphasizes the role of technological progress and innovation in economic growth. He argues that economic growth leads to an increase in the standard of living and that economic policies should be designed to promote long-term economic growth.

Samuelson’s definition also recognizes the importance of the environment in economic decision-making, as environmental degradation can negatively impact economic growth and development.

Samuelson’s Growth definition of Economics represents a departure from earlier definitions that focused primarily on material welfare or scarcity and choice. Instead, it emphasizes the importance of economic growth and development to improve people’s lives over time.

In several ways, P.A. Samuelson’s definition of economic growth differs from those of Chanakya, Adam Smith, Marshall, and Robbins. Chanakya’s definition focuses on getting rich by doing good things and promoting the common good. Samuelson’s definition, on the other hand, focuses on how societies use scarce resources to grow their economies.

Adam Smith’s definition focuses on the “invisible hand” and how the market self-regulates. In contrast, Samuelson’s definition focuses on the role of government intervention in promoting economic growth. Marshall’s definition focused on material welfare, while Samuelson focused on economic growth to improve living standards.

Lastly, Robbins’ definition puts more emphasis on scarcity and individual choice. In comparison, Samuelson’s definition emphasises economic growth as a way to make more resources available and improve the well-being of society as a whole.

Unlike other old definitions of economics, P.A. Samuelson’s growth definition of economics can be expressed mathematically as follows:

Y = ƒ(K,L,H,N)

Where,

Y represents the output of goods and services,

K represents capital, L represents labour,

H represents technology, and

N represents natural resources.

According to Samuelson, the main focus of economics is to increase the output of goods and services, which can be achieved by increasing the factors of production, such as capital, labour, technology, and natural resources. This mathematical representation highlights the importance of these factors in the production process and their impact on economic growth.

By maximizing the production function, countries can achieve sustained economic growth and improve the standard of living of their citizens.

Characteristics or Features of P.A Samuelson’s Definition of Economics

Focus on economic growth: P.A. Samuelson’s definition of economics strongly emphasises economic growth as the primary goal of the economy. Samuelson believed economic growth was necessary to improve people’s living standards and achieve societal welfare.
Interdisciplinary approach: The definition incorporates insights from various social sciences, such as sociology, psychology, and political science, to understand the complex nature of economic phenomena. Samuelson believed a multidisciplinary approach is necessary to analyze and solve economic problems.
Rational behaviour assumption: Samuelson’s definition assumes that individuals act rationally to maximize utility or satisfaction. This means that people make decisions based on their preferences and the available information and seek to achieve the best possible outcome for themselves.
Market-oriented perspective: Samuelson’s definition views the market system as the most efficient way to allocate resources and produce goods and services. He believed a competitive market system encourages innovation, efficiency, and productivity.
Dynamic and evolving concept: Samuelson’s definition recognizes that the economy is constantly changing and evolving. He believed economic analysis must be dynamic and adaptive to the changing economic environment.
Global perspective: Samuelson’s definition recognizes that economic problems and issues are not limited to national boundaries. He believed that economic analysis must be conducted globally to address the challenges of globalization, international trade, and economic development.

Supporters of P.A. Samuelson’s Growth definition of Economics

P.A. Samuelson’s definition of economics has been widely accepted and supported by many economists, policymakers, and academics. Some prominent supporters of his definition include Nobel laureates like Paul Krugman, Joseph Stiglitz, and Amartya Sen, who have praised his contributions to economic theory and policy.

Samuelson’s emphasis on economic growth, multidisciplinary approach, and rational behaviour assumption has influenced modern economics’ development and contributed to understanding economic phenomena. Moreover, his global perspective has helped to promote international cooperation and understanding in economic policymaking.

Criticisms of P.A. Samuelson’s Growth definition of Economics

P.A Samuelson’s Growth definition of Economics has faced several criticisms from various economists. Critics of Samuelson’s definition include notable economists such as Amartya Sen, Robert Solow, and Joseph Stiglitz. Here are the major criticisms:

Overemphasis on Growth: Some critics argue that Samuelson’s definition puts too much emphasis on economic growth and ignores other important aspects of the economy, such as income distribution, environmental sustainability, and social welfare.
Limited Scope: Another criticism is that the definition is too narrow, focusing only on producing and distributing goods and services and overlooking essential factors such as the role of government and institutions in the economy.
Neglect of Human Development: Samuelson’s definition has been criticized for overlooking the importance of human development and well-being. Critics argue that the ultimate goal of economic growth should be to improve the quality of life for individuals rather than increase the production of goods and services.
Ignorance of Inequality: Some economists argue that Samuelson’s definition fails to account for the unequal distribution of wealth and resources in society, which can significantly impact economic growth and development.
Not Comprehensive: Finally, critics argue that Samuelson’s definition is not comprehensive enough and fails to capture the complexity of the modern economy. Some argue it is too focused on traditional macroeconomic measures such as GDP and ignores the role of technology, globalization, and other emerging trends.

Arthasastra and Chanakya's Definition of Economics

Chanakya was the title given to Vishnugupta, an ancient Indian statesman, philosopher, and advisor to the Mauryan emperor Chandragupta Maurya. Kautilya was his given name, and he is also sometimes referred to as Chanakya or Chanakya Pandit. He is famous for his treatise on politics and economics, the Arthashastra, which remains an important work in Indian political theory and economics.

Chanakya's Concept of Economics

Chanakya's definition of economics can be found in his book, the Arthashastra, written in ancient India around 300 BCE. According to Chanakya (Kautilya), economics studies wealth production, distribution, and consumption.

In the Arthashastra, Chanakya emphasizes the importance of economic growth and development to achieve society's overall welfare. He argues that the state should actively promote economic activity and ensure wealth is distributed fairly among its citizens.

Chanakya also recognized the importance of non-material aspects of wealth, such as education and health, in achieving overall economic well-being. He emphasized the importance of investing in education and healthcare to increase human capital and promote economic growth.

Furthermore, Chanakya recognized the importance of economic policies and institutions in promoting economic growth and development. He emphasized the need for sound economic policies and institutions to promote economic growth and ensure wealth is distributed fairly among its citizens.

Main ideas of Chanakya in Arthasastra:

Chanakya's book, the Arthashastra, covers various economics-related topics. Some of the main ideas on economics contained in the book include:

1. Taxation: Chanakya emphasized the importance of taxation to generate revenue for the state. He advocated for a fair and just tax system based on the ability to pay and not overly burdensome on the people. 2. Trade: Chanakya recognized the importance of trade for economic growth and development.

He encouraged the development of trade routes and the establishment of markets where goods and services could be exchanged. 3. Agriculture: Agriculture was seen as a key sector of the economy in Chanakya's time, and he recognized the importance of land and water resources for agricultural production. He advocated for developing irrigation systems and other infrastructure to support agriculture. 4.

State intervention: Chanakya believed the state had a role in promoting economic growth and development. He advocated for state economic intervention through subsidies, price controls, and regulations. 5. Economic diplomacy: Chanakya recognized the importance of international trade and diplomacy for economic growth and development.

He encouraged the development of friendly relations with neighbouring states and the establishment of trade agreements and alliances.

Although Chanakya's ideas on economics and politics were influential in ancient India, he is not typically considered the father of economics. There are a few reasons for this. Firstly, Chanakya's ideas on economics were focused primarily on promoting state power and the well-being of society rather than on the individual pursuit of self-interest, which is often emphasized in modern economics.

Secondly, Chanakya's ideas on economics were not widely known outside of India until relatively recently. It was not until the British colonial period that European scholars became interested in ancient Indian texts such as the Arthashastra.

Finally, the modern discipline of economics developed in Europe in the 18th and 19th centuries, with the works of Adam Smith, Karl Marx, and others. These scholars developed new theories and methods for understanding economic phenomena distinct from the ideas in ancient Indian texts such as the Arthashastra.

Chanakya's ideas on economics were not the direct roots of modern economic theory; his book, the Arthashastra, did play an essential role in the intellectual history of economics. The Arthashastra is a comprehensive treatise on ancient India's politics, economics, and society around 300 BCE.

It covers a wide range of topics related to economics, including taxation, trade, agriculture, and the state's role in promoting economic growth and development.

The Arthashastra was an influential work in ancient India, and its ideas on economics and politics continued to be studied and debated for centuries. Many later Indian scholars drew on the ideas in the Arthashastra in their work on economics and politics.

During the British colonial period in India, European scholars began to take an interest in ancient Indian texts such as the Arthashastra. The ideas in these texts impacted the development of economic thought in Europe. For example, the British economist James Steuart drew on ideas from the Arthashastra in his work on economics in the 18th century.

Limitations of Chanakya's Arthasastra

While Chanakya's ideas on economics were influential in their time, some limitations to his approach are worth considering. Some of these limitations include the following:

1. Limited focus on individual welfare: Chanakya's approach to economics was primarily focused on the welfare of the state rather than that of individual citizens. While he recognized the importance of trade and agriculture for economic growth and development, he did not place as much emphasis on the welfare of individual people. 2.

Heavy reliance on state intervention: Chanakya believed the state had a key role in promoting economic growth and development. While some degree of state intervention may be necessary, there is a risk that too much state intervention can lead to inefficiency, corruption, and other negative outcomes. 3.

Lack of emphasis on market forces: Chanakya's approach to economics did not emphasize the role of market forces in driving economic growth and development. While he recognized the importance of trade and commerce, he did not fully appreciate how market forces can create incentives for innovation and productivity. 4.

Limited recognition of global economic interdependence: Chanakya's approach to economics was primarily focused on his state's economy. While he recognized the importance of international trade and diplomacy, he did not fully appreciate how economic activity in one part of the world can impact other parts.
