Who gave the scarcity centric definitions of economics ?

Question

Accepted Answer

Option 2, Robbins, is the correct answer because Lionel Robbins is renowned for his scarcity-centric definition of economics. In his seminal work "An Essay on the Nature and Significance of Economic Science" published in 1932, 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 scarcity and the necessity of making choices, which is central to economic theory. Robbins' definition shifted the focus of economics from wealth and welfare to the allocation of scarce resources, making it a pivotal moment in the history of economic thought.

Now, let's explain why the other options are incorrect:

1. **Marshall**: Alfred Marshall is known for his contributions to microeconomics and welfare economics, particularly through his book "Principles of Economics" published in 1890. Marshall's definition of economics focused on the study of mankind in the ordinary business of life, emphasizing the role of human welfare and economic activities. His approach was more about the practical aspects of economics rather than the theoretical focus on scarcity.

3. **Samuelson**: Paul Samuelson was a prominent economist known for his work in modern economic theory and his textbook "Economics," which has educated generations of economists. While Samuelson contributed significantly to various economic theories, including welfare economics and public goods, he did not specifically define economics in terms of scarcity. His work was more about synthesizing existing economic theories and applying mathematical methods to economics.

4. **Robinson**: Joan Robinson was a notable economist associated with the Cambridge School of Economics. She made significant contributions to economic theory, particularly in the areas of imperfect competition and economic growth. However, she did not provide a scarcity-centric definition of economics. Her work was more focused on the dynamics of markets and the critique of neoclassical economics.

In conclusion, Lionel Robbins' definition of economics as the study of scarce resources and their allocation is why Option 2 is the correct answer. His emphasis on scarcity and choice fundamentally shaped modern economic thought, distinguishing his definition from those of other economists.
