Activity 01
Graphing Stations: Tariff and Quota Effects
Prepare stations with base supply-demand diagrams for a domestic market. At the tariff station, students shift the import supply curve and label new equilibrium, surpluses, and deadweight loss. At the quota station, they cap quantity and compare outcomes. Groups rotate, discussing differences in 5 minutes per station.
Differentiate between tariffs and quotas in terms of their impact on imports and domestic prices.
Facilitation TipIn Graphing Stations, circulate with colored pencils and ask each group to label their welfare areas before sharing, ensuring every student connects shaded regions to real economic trade-offs.
What to look forPresent students with a scenario: 'Country A imposes a quota of 10,000 units on imported widgets.' Ask them to write down: 1. The primary goal of this policy. 2. One potential negative consequence for consumers. 3. One potential positive consequence for domestic producers.

Activity 02
Role-Play: Trade War Simulation
Assign roles to countries: one imposes a tariff or quota, others represent exporters and consumers. Groups negotiate responses like retaliation or subsidies over three rounds. Debrief with surplus changes on shared diagrams to link actions to economic impacts.
Analyze how a tariff creates a trade-off between producer surplus and consumer welfare.
Facilitation TipDuring the Trade War Simulation, assign roles clearly and set a 5-minute countdown for each negotiation round to keep energy high and prevent side conversations.
What to look forFacilitate a class debate using the prompt: 'Should governments prioritize protecting domestic industries through protectionist measures, even if it leads to higher prices for consumers and potential trade wars?' Encourage students to use specific examples of tariffs, quotas, or subsidies in their arguments.

Activity 03
Case Study Carousel: Real Protectionism
Set up four stations with cases like EU butter quotas or Chinese subsidies. Groups analyze one case for 8 minutes: identify measure type, diagram effects, predict partner responses. Rotate twice, then whole-class share key insights.
Predict the likely response of trading partners to the imposition of protectionist measures.
Facilitation TipIn the Case Study Carousel, place a timer on each poster and require students to rotate in pairs, recording one key insight per case to hold them accountable for engagement.
What to look forProvide students with a blank supply and demand diagram for a specific imported good. Ask them to draw and label the effects of a specific protectionist measure (e.g., a tariff). Then, ask them to briefly explain how consumer surplus and producer surplus change.

Activity 04
Debate Pairs: Protectionism Pros and Cons
Pairs prepare arguments for and against a specific measure like tariffs, using surplus data. Switch sides midway. Conclude with whole-class vote and diagram vote on net welfare, reinforcing trade-offs.
Differentiate between tariffs and quotas in terms of their impact on imports and domestic prices.
Facilitation TipFor Debate Pairs, provide a simple scorecard so peers can track arguments based on evidence from tariffs, quotas, or subsidies, not just rhetoric.

Generate Complete Lesson→A few notes on teaching this unit
Teachers should start with the simplest tool—graphs—because supply and demand diagrams make the invisible visible: who gains, who loses, and where the losses hide. Research shows that when students physically shade areas and label welfare changes, they retain the deadweight loss concept years later. Avoid lecturing on welfare triangles without first letting students discover them through structured tasks. Use real disputes like Boeing-Airbus to show how subsidies ricochet across borders, but only after students have wrestled with the mechanics in simulations.
Students should leave able to explain how tariffs, quotas, subsidies, and non-tariff barriers shift supply and demand, redistribute surplus, and create market distortions. They should also justify positions on protectionism using evidence from graphs, simulations, and case studies.
Watch Out for These Misconceptions
During Graphing Stations, watch for students who assume tariffs always improve the domestic economy overall.
Have them shade producer surplus gains in one color and consumer surplus losses plus deadweight losses in another, then calculate total welfare to see the net loss.
During the Trade War Simulation, watch for students who treat quotas and tariffs as identical in their effects.
Ask them to compare revenue raised by a tariff versus quota rents captured by importers, and to brainstorm why quotas may encourage smuggling in their simulation.
During Case Study Carousel, watch for students who conclude that subsidies only help the domestic firm and do not affect international trade.
Direct them to the Airbus-Boeing case materials to identify how lower export prices displaced foreign competitors and provoked retaliatory tariffs.
