Evolution in the Definition of Economics

The definition of economics has nevertheless dynamically changed, reflecting changes in the economic environment as well as improvements in knowledge of people’s behaviour and their use of resources. Initially, economics was defined mainly as a science of wealth and markets. But as the years have gone by, the definition of health has evolved to embrace psychological, social, and environmental factors. 

In its early stages, economics aimed to allocate scarce resources optimally to meet unlimited human needs. Adam Smith significantly contributed to this line of thought in his book, The Wealth of Nations (1776), where he outlined the role of markets, self-interest, and competition to achieve efficiency and economic success. Smith’s ideas over time acted as the premise of the classical school of economic thought, which remained prevalent throughout the nineteenth century. Over the years, economics has transformed to reflect the complexities of human societies and their pursuit of prosperity and welfare. Let us understand what is the definition of economics by different thinkers in today’s blog:

What is Economics Definition Based on Wealth?

If you ask, what is the definition of economics concerning wealth, then Adam Smith first proposed the idea. He emphasised the role of individual pursuit of wealth and self-interest as drivers of economic prosperity. In his seminal work, The Wealth of Nations (1776), Smith argued that when individuals are free to pursue their own financial goals and engage in free market exchanges, it leads to the growth of collective national wealth. This approach views economics primarily as studying wealth creation and market transactions. While the definition economics values personal economic freedom, critics argue that this can lead to income inequality by focusing solely on wealth accumulation.

What is the Definition of Economics Based on Scarcity?

A British economist, Lionel Robbins, introduced the scarcity-centred definition of economics in his 1932 book, ‘An Essay on the Nature and Significance of Economic Science’. Robbins defined economics as studying how societies manage scarce resources to fulfil unlimited human wants and needs. This approach underscores the need for efficient allocation of limited resources to meet the various demands within society. It emphasises the importance of rational choices, where individuals consider costs and benefits. However, critics argue that this definition based on scarcity and resource allocation may neglect wider social and ethical concerns. This definition does not directly address social justice or equitable resource distribution, which is essential for fostering fairness in society.

Define Economics with Respect to Growth

An American economist, Robert Solow, introduced the growth-oriented definition economics mainly by developing the Solow-Swan model. This model, introduced in 1932 in his influential work, ‘An Essay on the Nature and Significance of Economic Science’, highlights technological progress and capital accumulation as essential drivers of long-term economic growth. This approach seeks to identify factors contributing to sustained economic growth, raising living standards and promoting overall prosperity. However, critics warn that prioritising growth without regard for environmental sustainability may cause ecological harm. The emphasis on long-term growth can lead to neglecting immediate economic and social problems that require attention.

Define Economics with Respect to Welfare

John Maynard Keynes, a distinguished British economist, is closely associated with the welfare-centered approach to economics. During the Great Depression, Keynes introduced Keynesian economics through his influential work, The General Theory of Employment, Interest, and Money (1936). He argued that government intervention plays a critical role in stabilising economies. He argued that government expenditure can create demand, provide employment opportunities and enhance the welfare of households when the economy is not performing well. This perspective aims at improving the standards of living for the citizens of society in aspects of employment, income and poverty. However, opponents noted that it can generate an instance where the government’s involvement interferes with markets. It can lead to waste creation and the wrong deployment of resources in a production facility.

Wrapping Up

The definition of economics has changed several times for various reasons. These changes also signify that the understanding of the economy has expanded, as does human behaviour and the nature of resources. While the economist Adam Smith painted a picture of the market and individual freedom with references to wealth for the so-called civilised societies, the economist Lionel Robbins shifted the focus of economic study to the essential human concept of scarcity and rationality to meet the dynamic needs of society. Subsequent allocations, for instance, by Robert Solow, specify the centrality of technology advancement for long-term development. Equally, the Keynesian welfare state, according to John Maynard Keynes, emphasises the role of government in maintaining social order. All these definitions highlight different aspects of economics: wealth, scarcity, growth, and welfare, and show how this science is relevant and has a goal of improving the condition of people and societies in a world that is constantly evolving.

The four critical definitions of economics are:

• Wealth-Centered Definition (Adam Smith): Economics is the scientific analysis of wealth, focusing on markets, self-interest and competition.

• Scarcity-Centred Definition (Lionel Robbins): Economics is a social science examining how people assign scarce resources to fulfil unlimited wants and needs and focus on the best ways.

• Growth-Centered Definition (Robert Solow): Economics is the science that describes fundamental causes of sustained economic growth, including technological advances, capital formation, and consequent enhancement of the standard of living.

• Welfare-Centered Definition (John Maynard Keynes): Economics is the subject matter of how best to increase the overall welfare of a population, focusing on the use of government to save us from the pitfalls of any economy, examples being unemployment, poverty and inequality.

What is the study of evolution?

The study of evolution in economics examines how economic changes unfold over time.
