Classical Economics and Monetarism

Classical economics and monetarism rely on abstract models and historical evidence, both of which benefit from active engagement. Students need to test abstract claims against real data and debate policy trade-offs to move beyond memorization. These activities convert theory into lived inquiry by having students argue, analyze, and apply ideas rather than passively absorb them.

• 45 min · Pairs

Structured Academic Controversy: Should the Fed Follow a Rule?

Pairs of students are assigned either the Monetarist (rules-based) or discretionary Fed position. Each pair prepares a two-minute argument, then switches sides and argues the opposite position, before both sides work together to write a joint policy recommendation that acknowledges the strongest points from each view.

Explain the core tenets of Classical economic theory and Say's Law.

Facilitation Tip

During the Structured Academic Controversy, assign roles explicitly so students must research both sides before defending a position.

What to look for

Pose the following to students: 'Imagine you are advising a new government. One group argues for minimal government intervention, believing markets will self-correct. Another group advocates for active monetary policy to manage unemployment and inflation. Which arguments from Classical economics and Monetarism would you present to support each side, and what are the potential risks of each approach?'

Activity 02

• Think-Pair-Share
• 25 min · Pairs

Think-Pair-Share: Is Say's Law True Today?

Present three modern scenarios: a technology sector that produces a product no one wants, a recession where firms are producing but households aren't buying, and a robust expansion. Students individually evaluate whether Say's Law holds in each case, then compare their reasoning with a partner before class discussion.

Analyze the Monetarist view on the role of money supply in the economy.

Facilitation Tip

For the Think-Pair-Share on Say’s Law, provide unemployment data for students to analyze in pairs before sharing out.

What to look for

Provide students with short scenarios describing economic events (e.g., a sudden increase in oil prices, a decrease in consumer confidence). Ask them to write one sentence explaining how a Classical economist would predict the market would respond and one sentence explaining how a Monetarist would suggest the central bank should react.

Case Study Analysis: The Great Inflation of the 1970s

Small groups read a one-page narrative about the Fed's stop-go monetary policy in the 1970s. Using Friedman's analysis, groups identify the 'long and variable lags' in monetary policy and write a brief memo recommending what the Fed should have done differently, citing Monetarist principles.

Critique the arguments against active government intervention in the economy.

Facilitation Tip

When analyzing the Great Inflation of the 1970s, give students primary sources from both Friedman and Keynesian economists to compare directly.

What to look for

On an exit ticket, ask students to define Say's Law in their own words and then explain one reason why Milton Friedman believed unpredictable monetary policy was harmful to the economy.

A few notes on teaching this unit

Start with the Great Inflation case to ground abstract theories in a concrete crisis. Use short readings from original sources—Smith’s ‘invisible hand,’ Ricardo’s labor theory, Friedman’s ‘monetary history’—to show how economists themselves framed the debate. Avoid lecturing on the nuances of each theory; instead, let students surface misunderstandings through structured tasks and then address them explicitly.

By the end of these activities, students should be able to distinguish between short-run fluctuations and long-run self-correction, defend policy positions using evidence, and explain why Friedman insisted on steady monetary rules. Success looks like clear reasoning, precise vocabulary, and the ability to critique assumptions in real-world cases.

Watch Out for These Misconceptions

• During the Think-Pair-Share activity on Say's Law, watch for students who claim classical economists believed unemployment never exists at any time.

  During the Think-Pair-Share, redirect by asking students to examine the provided unemployment data for frictional and structural unemployment. Have them mark up the data to show where the Classical claim holds and where it breaks down, then discuss how Say’s Law applies only to long-run self-correction.

• During the Structured Academic Controversy, watch for students who equate monetarism with simply printing more money.

  During the Structured Academic Controversy, provide Milton Friedman’s own words on the ‘long and variable lags’ of monetary policy. Ask students to find where Friedman warns against discretionary action and instead advocates for steady rules, then debate how this differs from ‘printing money’ narratives.

• During the Case Study Analysis of the Great Inflation of the 1970s, watch for students who dismiss Say’s Law entirely because of the Great Depression.

  During the Great Inflation case study, have students create a timeline marking where Say’s Law, Keynesian short-run dynamics, and monetarist critiques apply. Ask them to explain why the Great Inflation does not disprove Say’s Law in the long run, but why it challenges Classical confidence in quick self-correction.
