Lionel Robbins’ Definition of Economics – Scarcity and Choice Definition

Introduction of Lionel Robbins:

Lionel Robbins (1898-1984) was a British economist who contributed significantly to economics. He was a professor of economics at the London School of Economics and Political Science and served as the head of the economics department there. Robbins is best known for his definition of economics, emphasising the concept of scarcity and the importance of individual choices.

Robbins challenged the traditional views of Economics put forth by earlier economists such as Chanakya, Adam Smith, and Alfred Marshall. Marshall’s attempt to provide a complete and flawless definition of Economics centred on material welfare was widely accepted, and many believed that the study of Economics had matured.

However, in 1932, Robbins published “An Essay on the Nature and Significance of Social Science,” introducing a new perspective on Economics. According to Robbins, Economics is a social science that deals with the problem of scarcity and the choices individuals make to satisfy their needs and wants. This new definition sparked debate in the field and challenged the traditional ideas of Economics. Robbins’ definition states that “Economics is the science that studies human behavior as a relationship between ends and scarce means that have alternative uses.”

Lionel Robbins’ Scarcity and Choice definition of Economics:

Robbins’ definition of economics is based on scarcity, which refers to the fact that resources are limited while human wants are unlimited. According to Robbins, the study of economics is concerned with the allocation of scarce resources among competing uses.

Lionel Robbins' Scarcity Definition of Economics

Robbins defined economics as “the science which studies human behavior as a relationship between ends and scarce means which have alternative uses.” This definition emphasizes the concept of choice, as individuals must choose how to allocate scarce resources among competing uses. Robbins believed that the study of economics should focus on understanding how individuals make these choices and how these choices affect the allocation of resources.

Robbins’ definition also emphasizes the importance of subjective values in economic decision-making. According to Robbins, individuals’ choices are based on their subjective values and preferences, which may differ from one individual to another. This means that economic analysis must consider the diversity of individual preferences and the subjective nature of value.

Characteristics or Features of Robbins’ Definition of Economics:

  1. Emphasis on Scarcity: Robbins’ definition of economics emphasizes the concept of scarcity, which is central to understanding economic decision-making. Scarcity means that resources are limited, and individuals must choose how to allocate these resources among competing uses.
  2. Importance of Individual Choices: Robbins’ definition also emphasizes the importance of individual choices in economic decision-making. Individuals must make choices about how to allocate scarce resources based on their subjective values and preferences.
  3. Focus on Allocation: According to Robbins, the economics study allocates scarce resources among competing uses. Economics is concerned with understanding how resources are distributed among individuals and groups.
  4. Subjective Nature of Value: Robbins’ definition emphasizes the subjective nature of value in economic decision-making. Individuals have different values and preferences, and these subjective factors are essential to economic choices.
  5. Positive and Normative Analysis: Robbins believed that economics should be concerned with both positive analysis (i.e., the description and explanation of economic behaviour) and normative analysis (i.e., the prescription of policy recommendations).

Supporters of Robbins’ Scarcity and Choice definition of Economics:

Robbins’ definition of economics has been widely accepted and influential in shaping the field of economics. Many economists, particularly those in the neoclassical tradition, support Robbins’ emphasis on scarcity, individual choice, and the subjective nature of value. Some notable supporters of Robbins’ definition of economics include Milton Friedman, Friedrich Hayek, and George Stigler.

Criticisms of Robbins’ Scarcity and Choice definition of Economics:

  1. Narrow Definition: One criticism of Robbins’ definition of economics is that it is too narrow and limited in scope. Critics argue that Robbins’ focus on scarcity and individual choice neglects essential aspects of economic behaviour, such as social and cultural factors that influence economic decisions.
  2. Overemphasis on Rationality: Another criticism of Robbins’ definition is that it overemphasizes the role of rationality in economic decision-making. Critics argue that individuals may not always make rational choices and that emotions, biases, and other non-rational factors can influence economic decisions.
  3. Neglect of Distributional Issues: Robbins’ definition also neglects distributional issues, such as the distribution of wealth and income. Critics argue that economics should be concerned with efficiency and equity and that Robbins’ definition places too much emphasis on efficiency.
  4. Lack of Policy Relevance: Some critics argue that Robbins’ definition of economics has limited policy relevance, focusing on describing and explaining economic behaviour rather than prescribing policy recommendations.
  5. Lack of Historical Perspective: Critics argue that Robbins’ definition of economics lacks a historical perspective. By focusing solely on individual choice and allocating scarce resources, Robbins neglects the broader social, political, and historical context in which economic decisions are made.
  6. Inability to Address Externalities: Lionel Robbins’ definition of economics also neglects the issue of externalities. Externalities refer to the costs or benefits of economic activities that are not reflected in market prices. Critics argue that economics must address externalities to promote sustainable and equitable economic growth.

The Superiority of Robbins’ Definition of Economics to other definitions of Economics by Chanakya, Marshall, and Adam Smith (Why and How is Robbins’ Definition Superior to other definitions)

  1. Scarcity and Choice: Robbins’ definition of Economics emphasizes the problem of scarcity and individuals’ choices to satisfy their needs and wants. This is a significant improvement over Adam Smith’s definition, which focuses on accumulating wealth through the division of labour and specialization. Robbins’ definition is more comprehensive and considers limited resources, and individuals must choose between alternative uses.
  2. Subjective Nature of Value: Robbins’ definition recognizes the subjective nature of value, which Marshall’s definition fails to address. Marshall’s definition centres around material welfare, which assumes everyone has the same wants and needs. Robbins, on the other hand, acknowledges that value is subjective and varies from person to person. This is an important consideration when studying human behaviour and decision-making.
  3. Practical Point of View: Robbins’ definition is practical, unlike Chanakya’s, which focuses on moral and ethical considerations. While moral and ethical considerations are important, they do not comprehensively understand economic behaviour. Robbins’ definition is grounded in the reality of scarcity and individuals’ resource allocation choices.
  4. Universal Applicability: Robbins’ definition is universal and applicable to all societies, unlike Marshall’s definition, which centres around material welfare in capitalist societies. Robbins’ definition recognizes that the problem of scarcity and individuals’ choices to allocate resources exist in all societies, regardless of their economic system.
  5. Emphasis on Human Aspect: Robbins’ definition emphasises the human aspect of Economics, unlike Adam Smith’s definition, which focuses on accumulating wealth through the division of labour and specialization. Robbins’ definition recognizes that Economics is a social science that deals with human behaviour and decision-making.

In summary, Lionel Robbins’ definition of Economics is superior to Marshall’s, Adam Smith’s, and Chanakya’s definitions because it takes into account the problem of scarcity and the choices that individuals make to allocate resources, recognizes the subjective nature of value, has a practical point of view, is universally applicable, and places a greater emphasis on the human aspect of Economics.
