The counter-revolution: monetarism, expectations and the free-market revival

Detail

1. Stagflation breaks the Keynesian consensus (1970s)

• Stagflation means stagnation plus inflation. Prices rise fast while output is weak and unemployment is high.
• Cause in the 1970s: the oil shocks of 1973 and 1979.

• Oil prices jumped → production cost rose for every firm → firms raised prices and cut output → high inflation and high unemployment came together.

• Phillips curve: the idea that inflation and unemployment move in opposite directions. It says a country can "buy" lower unemployment by accepting higher inflation.

• In the 1970s both went up together, so this simple trade-off failed.
• Keynesian demand management (spending more to cut unemployment) now seemed only to add inflation. This opened the door to the "counter-revolution".

2. Monetarism (Milton Friedman)

• Monetarism: the school that says the money supply (the total money in the economy) is the main driver of inflation and nominal output (output valued at current prices).
• Key work: A Monetary History of the United States (1963, with Anna Schwartz).
• It blamed the Great Depression on the US Federal Reserve. The Fed let the money supply shrink ("monetary contraction").

• Keynes had blamed a lack of demand. Friedman blamed bad central-bank policy.

• Friedman won the Nobel in 1976.

• His famous line: "Inflation is always and everywhere a monetary phenomenon."

Quantity equation: MV = PY (cross-ref the money topic)

• M = money supply. V = velocity, meaning how many times one rupee is spent in a year. P = price level. Y = real output.
• Worked example: M = ₹100 crore, V = 5, Y = 250 units.
• PY = 100 × 5 = 500, so P = 500 ÷ 250 = 2.

• If M rises 10% to ₹110 crore and V and Y stay the same, then P = 550 ÷ 250 = 2.2. That is a 10% price rise.

• Growth form (approximate): %ΔM + %ΔV ≈ %ΔP + %ΔY.

• If money grows 12%, velocity is stable and real GDP grows 7%, then inflation ≈ 12 − 7 = 5%.

• Monetarist message: when V is stable, too much money growth means inflation.

Policy: the k-percent rule

• Under this rule, the central bank lets the money supply grow at a fixed rate (k%) every year, whatever happens in the economy.
• Usually k is set close to the long-run real growth rate. Then the extra money only matches the extra goods and does not push prices up.
• Why use a rule? Friedman distrusted discretion (officials choosing policy case by case). Policy works with long, variable time lags, so "fine-tuning" often makes things worse.

Natural-rate hypothesis (Friedman; also Phelps)

• Natural rate of unemployment: the unemployment that remains when the economy is in balance. It comes from job-search time, skill mismatch and similar causes, not from weak demand.
• The chain:
• The government prints money → inflation rises above what workers expected → real wages fall for a while → firms hire more → unemployment falls in the short run.

• Workers learn and ask for higher wages → real wages go back up → unemployment returns to the natural rate.

• Result: the long-run Phillips curve is vertical at the natural rate. In the long run, more inflation does not buy lower unemployment. It only gives higher inflation.

3. Chicago school and the Cantillon effect

• Chicago school: the free-market school at the University of Chicago. It stands for monetarism, deregulation (removing government rules on business) and rational choice (the idea that people weigh costs and benefits when they decide).
• Cantillon effect (Richard Cantillon, c. 1730): new money helps whoever receives it first, before prices rise.
• Example: the central bank creates money and buys bonds from banks. Banks and asset holders spend or invest it first, while prices are still old. Share and property prices rise. A daily-wage worker gets the money last, after prices have already gone up.
• It is used to link quantitative easing (QE) to asset-price inequality. QE means a central bank buys bonds on a large scale to push money into the economy.

4. Expectations: adaptive vs rational

	Adaptive expectations	Rational expectations
How formed	From past values, correcting past errors slowly	From all available information and the correct model of the economy
Associated with	Friedman, Phelps	Muth (1961), Lucas, Sargent
Policy result	Policy can fool people in the short run	Policy ineffectiveness: systematic policy cannot keep fooling people

• Adaptive, worked example: inflation was 6% last year. People expect about 6% this year. If it turns out to be 8%, they only raise next year's guess part of the way, say to 7%. So for a while, surprise inflation can raise output.
• Rational, worked example: the central bank has a known habit of printing more money whenever unemployment rises. People expect this, so wages and prices go up at once. Real output does not change.
• Policy ineffectiveness proposition: only surprise policy can change real output. A predictable (systematic) policy only changes prices.

5. Lucas critique (1976)

• Statement: you cannot predict the effect of a new policy from past data. When the policy changes, people change their behaviour.
• Example: an old model shows that "more inflation gave lower unemployment". If the government tries to use this pattern again and again, people start to expect the inflation, and the pattern disappears.
• Impact: economists began to build models from how people make decisions ("micro-foundations"), not from past averages alone.

6. Real business cycle theory and time inconsistency (Kydland–Prescott)

• Real business cycle (RBC) theory (Kydland–Prescott, 1982): booms and slumps are efficient responses to real shocks, such as changes in technology. They are not failures of demand.

• If business cycles are efficient, then stimulus to smooth them is not needed.

• Time inconsistency (Kydland–Prescott, 1977; Nobel 2004): a plan that looks best today stops looking best later. So the policymaker is tempted to break its promise.

• The chain: the central bank promises low inflation → people set wages on that basis → the bank is tempted to create surprise inflation to raise jobs for a while → people expect this → they build high inflation into wages → the economy ends up with high inflation and no extra jobs.

• The fix: rules plus independent central banks that are legally bound to a target. Such promises are credible (believable).

7. India's flexible inflation targeting (FIT): the rules-based logic in practice

• Flexible inflation targeting means the central bank's main job is to hit an inflation target, but it may also look at growth ("flexible").
• Legal basis: the RBI Act was amended in 2016 [3].
• Section 45ZA: the Central Government, in consultation with the RBI, fixes the inflation target in terms of CPI once every five years [3].

• Section 45ZB: sets up the Monetary Policy Committee (MPC) [3].

• The Central Government, in consultation with the RBI, announced the 4% CPI inflation target in 2016 [5].

• Target: CPI inflation of 4% ± 2%, so the band is 2%–6%.
• First period: 5 August 2016 – 31 March 2021 [2].
• Retained at the 2021 review for 1 April 2021 – 31 March 2026 [2].
• 2026 review (update): on 25 March 2026, the government retained the 4% target and the ±2% band for 1 April 2026 – 31 March 2031 [2]. (NCERT scaffold: target applied for 2021–26, retention "to be verified". It is now confirmed.)

• Before this review, the RBI released a discussion paper (August 2025). It asked four questions [3]:

  • Should the target be headline or core inflation? Food is 45.9% of the CPI basket.
  • Is 4% still the right level?
  • Should the ±2% band be narrowed, widened or removed?
  • Should India move to a range target with no single point?

• MPC: six members. Three are from the RBI: the Governor (chair), a Deputy Governor and one RBI officer. Three are external members [2][3].

• First set up on 29 September 2016 [3].

• Quorum (minimum members needed for a meeting) is four. Each member has one vote. On a tie, the Governor has a casting vote [2].

• Failure to meet the target: average inflation stays above 6% or below 2% for any three consecutive quarters [2]. The RBI must then report to the government [3].

• Operating target: the weighted average call rate (WACR), the average overnight interest rate at which banks lend to each other. The RBI manages liquidity (money available in the banking system) to keep WACR in line with the repo rate [2].
• Record: average inflation was about 3.9% in the first four years of FIT. The 6% upper limit was then breached during the pandemic and the Russia–Ukraine conflict [3].

8. Tinbergen rule

• Jan Tinbergen: winner of the first economics Nobel (1969).
• Rule: you need at least as many policy instruments as independent targets. One instrument per target.
• Example: a country wants to control both inflation and the exchange rate. The repo rate alone cannot do both. A second tool is needed, such as forex intervention (the RBI buying or selling dollars).
• Link to India: FIT gives the repo rate one main job, price stability. Growth is supported through fiscal and structural policy.

9. Market vs state: the Austrian school

• Austrian school (Carl Menger, Ludwig von Mises, Friedrich Hayek). It stresses:
• individual action: only individuals choose and act, not "society";
• subjective value: a good is worth what a person thinks it is worth to them;

• spontaneous order: markets coordinate millions of plans without a planner, through prices.

• Austrian business cycle theory:

• Cheap credit (interest rates kept artificially low) → firms start long, risky projects → this is malinvestment (investment in the wrong things) → savings cannot support all the projects → bust.

• Hayek: wrote The Road to Serfdom (1944), arguing that central planning leads step by step to loss of freedom.

• Nobel 1974, shared with Gunnar Myrdal, whose views were the opposite of his (Myrdal backed state planning and the welfare state).

• Economic calculation problem (Mises, 1920): without market prices for capital goods (machines, factories), central planners cannot know what is scarce. So they cannot allocate resources rationally.

• Link: Indian planning (Mahalanobis model, NCERT Class 11) relied on planners' choices, not market prices, for heavy-industry investment.

10. Supply-side economics

• Definition: growth comes from cutting taxes and regulation so that people have more reason to work, save and invest. This raises supply, not just demand.
• Linked to the Laffer curve (cross-ref taxation). The Laffer curve holds that above some tax rate, higher rates bring in less revenue, because people work, invest or report income less.
• Linked to Reaganomics (the policies of US President Reagan from 1981).
• India's September 2019 corporate tax cut (Taxation Laws (Amendment) Ordinance, 2019) [4]:
• Any domestic company may choose a 22% rate (earlier base rate 30%) from FY 2019-20, if it gives up all exemptions and incentives [4].
• Effective rate 25.17% including surcharge and cess [4].
  • Worked example: 22% × 1.10 (10% surcharge) = 24.2%. Then 24.2% × 1.04 (4% cess) = 25.17%.
• New manufacturing companies incorporated on or after 1 October 2019 may choose 15%, if they start production by 31 March 2023. Effective rate 17.01% [4].
• Companies that choose these rates do not pay Minimum Alternate Tax (MAT) [4]. MAT is a minimum tax charged on book profit so that companies cannot use exemptions to pay almost nothing.

11. Neoliberalism and the Washington Consensus

• Neoliberalism: a policy approach favouring free markets, deregulation, privatisation (selling state firms to private owners), trade liberalisation (cutting tariffs and import controls) and a smaller state.
• Milestones:
• Mont Pelerin Society (1947), founded by Hayek and others.
• Thatcher (UK, from 1979).

• Reagan (USA, from 1981).

• Washington Consensus (John Williamson, 1989): a list of market-friendly reforms promoted by Washington-based institutions (the IMF, the World Bank and the US Treasury) for developing countries. Cross-ref the BoP topic.

• Debate on India's 1991 reforms:
• "Neoliberal" view: the reforms came in a balance-of-payments crisis under IMF conditionality (conditions attached to the loan). They included delicensing, tariff cuts and disinvestment.
• "Home-grown" view: the reforms were gradual liberalisation that India chose itself. The state kept a large welfare role (food subsidy and, later, rural employment schemes). Some sectors opened slowly, and capital-account convertibility was never fully adopted.

12. Public choice theory

• Buchanan–Tullock, The Calculus of Consent (1962). Buchanan won the Nobel in 1986.
• Core idea: voters, politicians and bureaucrats are self-interested, just like buyers and sellers.
• So government failure is as real as market failure.

• Government failure means state action that makes outcomes worse. Market failure means markets giving bad outcomes, such as pollution or monopoly.

• Rent-seeking: trying to earn income by getting special favours from the state (licences, quotas, tariffs) instead of producing something of value.

• Example: under India's pre-1991 Licence Raj, firms spent effort lobbying for licences rather than on better products.

13. Arrow's impossibility theorem

• Kenneth Arrow, Social Choice and Individual Values (1951).
• Statement: no ranked voting system can turn individual preferences into a social ranking that meets all of a set of reasonable fairness conditions at the same time.

• The standard conditions are: any preferences are allowed; if everyone prefers A to B, society does too (Pareto); society's choice between A and B depends only on how people rank A vs B; and no dictator.

• Worked example (voting cycle, or Condorcet paradox): three voters rank three options.

• Voter 1: A > B > C. Voter 2: B > C > A. Voter 3: C > A > B.
• In pairwise votes: A beats B (2–1), B beats C (2–1), C beats A (2–1).

• So society's ranking goes round in a circle and has no clear winner.

• Link to public choice: majority voting can give unstable or manipulable results. This is one more source of government failure.

Prelims Hooks

• "Inflation is always and everywhere a monetary phenomenon": Milton Friedman (Nobel 1976). A Monetary History of the United States (1963) was co-written with Anna Schwartz, not with Phelps or Lucas.
• MV = PY: V is velocity of money, not volume. The k-percent rule means a fixed yearly money-growth rate.
• Natural-rate hypothesis: the long-run Phillips curve is vertical. The short-run curve slopes downward.
• Rational expectations were first proposed by Muth (1961) and developed by Lucas and Sargent. Adaptive expectations are linked to Friedman and Phelps.
• Lucas critique (1976), RBC theory (1982) and time inconsistency (1977; Nobel 2004) belong to Kydland–Prescott, except the Lucas critique, which is Lucas's alone.
• India's inflation target: 4% ± 2% CPI, retained on 25 March 2026 for 1 April 2026 – 31 March 2031. The target is set by the Central Government in consultation with the RBI (Section 45ZA), not by the MPC [2][3].
• MPC: 6 members (3 RBI + 3 external), quorum 4, and the Governor has a casting vote. Failure means inflation outside 2–6% for three consecutive quarters [2].
• Tinbergen rule: number of instruments ≥ number of targets. Tinbergen won the first economics Nobel (1969).
• Hayek and Myrdal shared the 1974 Nobel despite holding opposite views. The Road to Serfdom was published in 1944. The economic calculation problem is Mises (1920).
• September 2019 tax cut: 22% base rate (effective 25.17%). 15% for new manufacturing firms (effective 17.01%). No MAT for companies that choose these rates [4].
• Public choice: Buchanan–Tullock, The Calculus of Consent (1962); Buchanan won the Nobel in 1986. Arrow's impossibility theorem: Social Choice and Individual Values (1951).

Mains Points

• Rules vs discretion in Indian monetary policy (GS-III): time inconsistency and the Lucas critique justify a legally fixed target and an independent MPC. The 2026 retention of 4% ± 2% keeps expectations anchored [2]. However, food is 45.9% of the CPI basket [3], so supply shocks (monsoon, edible oil) can push inflation outside the band even though demand has not changed. This reopens the headline vs core debate and the Tinbergen problem of one tool (the repo rate) for several goals.
• Supply-side tax policy, effectiveness and cost: the 2019 corporate tax cut aimed to raise investment by lowering the effective rate to 25.17% [4]. Critics note that private investment responds to demand, not only to after-tax profit, and that the cut lost revenue in the short run. This is a Laffer-curve question: at what rate does revenue actually fall?
• Were the 1991 reforms neoliberal? One side points to IMF conditionality, delicensing and trade opening, in line with the Washington Consensus. The other side points to gradual sequencing, a large welfare state and controls on capital flows. A balanced answer calls the reforms "pragmatic liberalisation", which fits GS-III answers on growth and reforms.
• Market failure vs government failure (GS-II/III): public choice theory (rent-seeking under the Licence Raj) and the economic calculation problem explain the weaknesses of planning. Keynesian and Myrdal-style arguments still justify state action for public goods and equity. This supports the case for regulatory institutions (independent regulators, rule-based fiscal and monetary frameworks) over both a pure market and heavy central planning.
