These questions account for a disproportionate share of prelims factoids and mains writing prompts, because they together define the boundary of the subject as the syllabus frames it. This article consolidates all four into a single, clean reference. You will meet Adam Smith and the 1776 publication that founded modern economics, walk through the classical definitions of micro and macro analysis, learn the M3 money-supply formula used by the Reserve Bank of India and decode the relative, absolute, rural, urban and multidimensional forms of poverty measured by the NSO and NITI Aayog. The goal is not encyclopedic depth but exam-grade clarity you can reproduce in two minutes in an answer booklet. ![Economics for UPSC: Micro, Macro, Father of Economics and Types of Poverty](https://r2.anantamias.com/wp-content/uploads/2026/04/father-of-economics-content-1.jpg) ## Quick Facts at a Glance | Item | Detail | | ---- | ------ | | Father of Economics | Adam Smith (1723-1790) | | Foundational book | An Inquiry into the Nature and Causes of the Wealth of Nations (1776) | | Father of Modern Economics | Often attributed to Paul A.

Earlier traditions existed — **Kautilya's Arthashastra** (around 300 BCE) is a pioneering Indian treatise on political economy, and the mercantilist and physiocrat schools of Europe offered their own frameworks — but none produced a theoretical system broad enough to count as the discipline's foundation. That changed in 1776 when Adam Smith, a Scottish moral philosopher at the University of Glasgow, published *An Inquiry into the Nature and Causes of the Wealth of Nations*. The book introduced the ideas of the invisible hand, division of labour, self-interest-driven allocation, free trade and the labour theory of value. Smith is therefore universally called the **father of economics**. The discipline bifurcated in the 20th century. Alfred Marshall's 1890 *Principles of Economics* formalised the study of individual markets (microeconomics). After the Great Depression, **John Maynard Keynes** published *The General Theory of Employment, Interest and Money* in 1936 and reorganised the study of aggregate output, unemployment and inflation, founding modern macroeconomics. **Paul Samuelson's** 1948 textbook *Economics* unified the two streams in a single pedagogy and is why he is often called the father of modern economics. In India the classification of money supply and poverty lines has its own lineage. The Reserve Bank of India introduced the four-way money supply classification (M1, M2, M3, M4) on the recommendation of the **Second Working Group on Money Supply (1977)**. Poverty measurement has passed through the Lakdawala (1993), Tendulkar (2009), Rangarajan (2014) and most recently the NITI Aayog Multidimensional Poverty Index (2021, updated 2023) methodologies. ## Key Features of Economic Analysis ### Who is the Father of Economics **Adam Smith** is the father of economics because *The Wealth of Nations* (1776) was the first book to treat the production, distribution and exchange of wealth as a coherent, law-governed system. His concept of the **invisible hand** — that individuals pursuing self-interest unintentionally promote the public good — became the theoretical backbone of classical and neoclassical economics. Related attributions include Kautilya as the father of Indian economics, Keynes as the father of macroeconomics, Alfred Marshall as the father of neoclassical economics, and Samuelson as the father of modern economics. ### Microeconomics: The Study of Units **Microeconomics** analyses individual economic agents such as households, firms and industries. Its core problems are price determination, consumer equilibrium (utility maximisation), producer equilibrium (cost and revenue analysis), market structures (perfect competition, monopoly, monopolistic competition, oligopoly) and factor pricing. The chief tools are demand and supply curves, indifference curves, isoquants and game theory. Microeconomics answers questions like "Why did onion prices spike last month" or "How do two firms set output under Cournot competition". ### Macroeconomics: The Study of the Whole **Macroeconomics**, systematised by Keynes, studies economy-wide aggregates: GDP, GNP, aggregate consumption, investment, unemployment, inflation, money supply and balance of payments. Core models include the **IS-LM framework**, aggregate demand and aggregate supply (AD-AS), the Phillips curve and the Solow growth model. In India macroeconomic policy is jointly conducted by the Ministry of Finance (fiscal) and the Reserve Bank of India (monetary). ### The M3 Formula The Reserve Bank of India defines four monetary aggregates. **M3** is the headline broad money measure used in the weekly Statistical Supplement and in repo rate press releases. - M1 = Currency with the public + Demand deposits with the banking system + Other deposits with the RBI - M2 = M1 + Savings deposits of post office savings banks - M3 = M1 + Time deposits of the public with the banking system - M4 = M3 + All deposits with post office savings banks (excluding National Savings Certificates) M3 is therefore the broadest commonly cited money stock, and its growth rate is a key indicator of monetary conditions. As of March 2025, India's M3 stood at approximately INR 260 lakh crore. ### Types of Poverty - **Absolute poverty** — inability to afford a minimum basket of goods and services; measured in India historically by the Tendulkar and Rangarajan lines. - **Relative poverty** — income or consumption below a threshold linked to the societal mean (such as 50 per cent of median income). - **Rural vs urban poverty** — different consumption baskets and poverty lines; the Rangarajan Committee set 32 INR per day rural and 47 INR per day urban (2011-12 prices). - **Transient and chronic poverty** — time dimension of deprivation. - **Multidimensional poverty** — captured by NITI Aayog's MPI using 12 indicators across health, education and standard of living, showing 14.96 per cent of India's population as MPI poor in 2019-21, down from 24.85 per cent in 2015-16. ![Economics for UPSC: Micro, Macro, Father of Economics and Types of Poverty](https://r2.anantamias.com/wp-content/uploads/2026/04/father-of-economics-content-2.png) ## Significance for UPSC and General Knowledge - Prelims questions routinely ask who wrote *The Wealth of Nations* and when, or who is called the father of modern economics. - GS3 mains expects clean distinction between micro and macro when answering inflation, GDP or unemployment questions. - Economic Survey chapters rely on M3 growth, reserve money and broad money data; M3 is a staple of RBI-related MCQs. - NITI Aayog MPI releases and SDG monitoring directly feed into GS2 social justice and GS3 inclusive growth answers. - Essay papers on welfare state and inclusive growth benefit from the Smith-Keynes-Sen progression. - Interview boards often ask for your favourite economist and why, expecting both historical grounding and policy relevance. ## Detailed Analysis: Schools, Measurement and Policy Classical economics, founded by Smith and extended by David Ricardo and John Stuart Mill, emphasised free markets, the labour theory of value and Say's law ("supply creates its own demand"). The marginalist revolution of the 1870s brought in Jevons, Menger and Walras, who shifted focus to utility and marginal analysis, culminating in Alfred Marshall's neoclassical synthesis. Keynes challenged Say's law during the Great Depression, arguing that aggregate demand deficiency could lock an economy into unemployment equilibrium without active fiscal policy. Post-war economics has seen the monetarist counter-revolution led by Milton Friedman, the rational expectations school of Robert Lucas, the new Keynesian synthesis and most recently behavioural economics from Daniel Kahneman and Richard Thaler. In the Indian context, development economists such as V. K. R. V. Rao (national income accounting), P. C. Mahalanobis (planning), Amartya Sen (capability approach and poverty measurement) and Jagdish Bhagwati (trade) have made foundational contributions. Poverty measurement in India has evolved through multiple committees. The Lakdawala Committee (1993) used state-specific poverty lines. The Tendulkar Committee (2009) adopted a uniform national line based on mixed consumption baskets and estimated 21.9 per cent of India as poor in 2011-12. The Rangarajan Committee (2014) revised the line upwards and estimated 29.5 per cent. The NITI Aayog's Multidimensional Poverty Index, based on the global Alkire-Foster methodology developed by Oxford Poverty and Human Development Initiative, shifted the debate from income to deprivation across nutrition, child mortality, years of schooling, school attendance, cooking fuel, sanitation, drinking water, electricity, housing, assets, bank accounts and maternal health. ![Economics for UPSC: Micro, Macro, Father of Economics and Types of Poverty](https://r2.anantamias.com/wp-content/uploads/2026/04/wiki-img-15.jpg)Image: Wikipedia. [Source](https://en.wikipedia.org/wiki/Adam_Smith). ## Comparative Perspective The table below contrasts micro and macro analysis and places the M3 definition in the context of other monetary aggregates. | Dimension | Microeconomics | Macroeconomics | | --------- | -------------- | -------------- | | Unit of analysis | Individuals, firms, industries | Entire economy, sectors | | Key variables | Prices, output of a firm, wages | GDP, inflation, unemployment, money supply | | Main tool | Demand-supply, indifference curves | IS-LM, AD-AS, growth models | | Pioneer | Alfred Marshall | John Maynard Keynes | | Example question | Why are pulse prices rising | Why is CPI inflation above 6 per cent | | Policy relevance | Market regulation, competition policy | Monetary policy, fiscal policy | Monetary aggregates in India follow a clear hierarchy: M0 (reserve money) is the narrowest, M1 is narrow money, M3 is broad money, and M4 adds post-office deposits. M3 and M0 are the two most frequently reported in RBI press releases. ## Challenges and Criticisms Classical economics in the Smithian tradition has been criticised for assuming perfect information, rational behaviour and self-correcting markets. The 2008 global financial crisis revived heterodox critiques and a wave of behavioural and institutional economics. Measurement of macro aggregates faces its own problems: GDP ignores household work, environmental depletion and informal sector activity; the MCA 21 back-series revisions have repeatedly restated India's historical GDP numbers. Poverty estimation is a live controversy. The Tendulkar line was criticised as too austere; the Rangarajan line was never formally adopted. The NITI Aayog MPI has been praised for its multidimensional reach but questioned for relying on survey rounds (NFHS) rather than monthly consumption data. Money supply analysis has also evolved: in a digital-payment economy with rising UPI volumes and a pilot Central Bank Digital Currency (CBDC or e-rupee) rolled out since 2022, the traditional boundary between M1 and M3 is being renegotiated. ## Prelims Pointers - Adam Smith (1723-1790) is the father of economics; his 1776 book is *An Inquiry into the Nature and Causes of the Wealth of Nations*. - John Maynard Keynes is the father of macroeconomics; his 1936 book is *The General Theory of Employment, Interest and Money*. - Paul A.

Discuss with examples from the Indian economy. (250 words) - Define the two branches and their tools. - Use examples like inflation targeting (macro) and price subsidies (micro) that spill across. - Conclude with the integration in the new Keynesian synthesis and Indian policy practice. - Critically examine the evolution of poverty estimation in India from the Tendulkar Committee to the NITI Aayog Multidimensional Poverty Index.

These four ideas, taken together, form the foundational vocabulary that every Civil Services aspirant must command before moving to sectoral topics like banking, agriculture or international trade. Treat this article as your reference sheet. Return to it when you open the Economic Survey or the Union Budget, and the technical content will fall into place faster. In mains answers, citing Smith, Keynes, Samuelson and Amartya Sen at the right moment not only gives intellectual texture but signals conceptual command to the examiner. ## Frequently Asked Questions ### Who is the father of economics? Adam Smith, the Scottish philosopher who lived from 1723 to 1790, is called the father of economics. His 1776 book An Inquiry into the Nature and Causes of the Wealth of Nations introduced the ideas of the invisible hand, division of labour and self-interest-driven markets, laying the foundation of the modern discipline. ### Who is the father of modern economics? The title father of modern economics is commonly attributed to Paul A. Samuelson, whose 1948 textbook Economics integrated microeconomics and macroeconomics into a unified teaching framework. He received the Nobel Memorial Prize in 1970 for raising the general level of scientific analysis in economic theory. ### Why is the father of economics important for UPSC? Prelims regularly asks factual identifications about Adam Smith, The Wealth of Nations, Keynes, and the classical-Keynesian-monetarist progression. In mains and essay, the Smith-Keynes-Sen arc helps aspirants frame answers on free markets, welfare state, inclusive growth and policy responses to crises. ### How is microeconomics different from macroeconomics? Microeconomics studies individual units — households, firms, specific markets — using demand and supply, utility and cost analysis. Macroeconomics studies the economy as a whole — GDP, inflation, unemployment and money supply — using tools like IS-LM, AD-AS and growth models. Both are complementary and integrated in modern policy. ### What is the M3 formula in economics? In India, M3 is broad money calculated as M1 plus time deposits of the public with the banking system. M1 itself equals currency with the public plus demand deposits plus other deposits with the RBI. M3 is published weekly by the Reserve Bank of India and is the most widely tracked money supply aggregate. ### What are the types of poverty in economics? Economists classify poverty as absolute (inability to afford a minimum basket), relative (below a societal benchmark such as 50 per cent of median income), chronic versus transient (time dimension), rural versus urban (location-based baskets) and multidimensional (deprivation across health, education and living standards, as in the NITI Aayog MPI). ### How is the father of economics related to Indian economic thought? Smith's ideas of free trade and markets influenced Indian economic policy from the 1991 reforms onwards, though Indian economic thought traces further back to Kautilya's Arthashastra. Modern Indian economists such as V. K. R. V. Rao, P. C. Mahalanobis, Amartya Sen and Jagdish Bhagwati extended classical and Keynesian ideas to development problems. ### Why did Keynes challenge Adam Smith? Smith believed markets self-correct through the invisible hand, implying persistent unemployment cannot exist. Keynes, writing during the 1930s Great Depression, showed that aggregate demand deficiency could trap an economy in unemployment equilibrium and argued for active fiscal policy. This effectively founded macroeconomics as a separate branch.
