Behavioral Economics Basics

Active learning helps students see how cognitive biases shape their own decisions, not just textbook theory. When students experience anchoring or loss aversion firsthand, the concepts shift from abstract to personal, making the material more memorable and relevant to daily life.

• Ontario Curriculum Expectations
• Ontario Curriculum: Canadian and World Studies, Grades 11-12 (2015), The Individual and the Economy (CIE3M), B1.1. Explain the concept of scarcity and how it requires individuals, businesses, governments, and societies to make choices about how to allocate their resources.
• Ontario Curriculum: Canadian and World Studies, Grades 11-12 (2015), The Individual and the Economy (CIE3M), B1. Demonstrate an understanding of the concepts of scarcity, choice, and opportunity cost, and of how they affect the allocation of resources.
• Ontario Curriculum: Canadian and World Studies, Grades 11-12 (2015), The Individual and the Economy (CIE3M), B1.4. Analyse the factors of production and their role in the economy.

Activity 01

• Simulation Game
• 35 min · Small Groups

Simulation Game: Anchoring Bias Auction

Provide groups with identical items but different starting bid prices. Have students bid in rounds, then reveal true values and discuss how anchors influenced offers. Debrief with charts comparing bids across groups.

Explain how cognitive biases can lead to irrational economic decisions.

Facilitation Tip

During the Anchoring Bias Auction, set a 30-second timer for each bid to prevent overthinking and force reliance on the initial anchor.

What to look for

Provide students with a scenario describing a consumer choice, such as buying a new phone. Ask them to identify one cognitive bias that might influence the decision and briefly explain how it works in this context. Then, ask them to suggest one 'nudge' a company might use to encourage a specific purchase.

Activity 02

• Experiential Learning
• 45 min · Pairs

Design Challenge: Nudge Creation

Present scenarios like school cafeteria choices. Pairs brainstorm and prototype nudges, such as tray layouts or labels, to promote healthy eating. Groups pitch ideas and vote on most effective ones.

Analyze a real-world example of 'nudges' used to influence behavior.

Facilitation Tip

For the Nudge Creation challenge, provide a short list of pre-screened nudges as examples so students can focus on tailoring rather than brainstorming from scratch.

What to look for

Pose the question: 'Is it ethical for businesses or governments to use nudges to influence our decisions?' Facilitate a class discussion where students debate the pros and cons, referencing concepts like autonomy, paternalism, and the potential for manipulation.

Activity 03

• Experiential Learning
• 30 min · Whole Class

Experiment: Loss Aversion Game

Distribute play money. Students play a game risking gains versus avoiding losses, tracking choices over rounds. Analyze class data to graph preferences and connect to real savings behaviors.

Critique the assumption of perfect rationality in traditional economic models.

Facilitation Tip

In the Loss Aversion Game, have students calculate their final scores out loud to highlight how loss framing affects their choices in real time.

What to look for

Present students with short descriptions of economic behaviors (e.g., following stock market trends, overspending during a sale, choosing the default option on a website). Ask them to quickly label which behavioral economics concept (anchoring, loss aversion, herd mentality, nudge) best explains each behavior.

Activity 04

• Case Study Analysis
• 40 min · Small Groups

Case Study Analysis: Herd Behavior Analysis

Share news clips of market bubbles or viral trends. Small groups identify herd signals, predict outcomes, and propose counter-nudges. Present findings to class for peer feedback.

Explain how cognitive biases can lead to irrational economic decisions.

Facilitation Tip

For the Herd Behavior Analysis case study, assign specific roles (e.g., influencer, skeptic) to guide students into debating the psychology behind trends.

What to look for

Provide students with a scenario describing a consumer choice, such as buying a new phone. Ask them to identify one cognitive bias that might influence the decision and briefly explain how it works in this context.

A few notes on teaching this unit

Teach these concepts through iterative cycles of experience, reflection, and application. Start with a relatable hook, like a viral product or a store sale, then let students test predictions in simulations. Avoid long lectures upfront; instead, use guided questions to surface misconceptions and correct them in the moment. Research shows that when students confront their own biases in controlled settings, they’re more likely to integrate behavioral economics into their decision-making outside the classroom.

Successful learning shows when students can identify biases in real-world examples and explain how nudges influence behavior. They should move from recognizing concepts to applying them in new scenarios, demonstrating both recall and transfer of knowledge.

Watch Out for These Misconceptions

• During the Anchoring Bias Auction, students may assume the highest bidder always has the best strategy.

  After the auction, compare final bids to the actual value of items. Ask students to reflect in journals: Which bids were too high? How did the starting price trick them into overvaluing items?

• During the Nudge Creation challenge, students might believe nudges only work on irrational people.

  Have students present their nudges to the class and ask peers to identify how the nudge preserves choice. Use their reactions to highlight that even 'rational' people benefit from subtle guidance.

• During the Loss Aversion Game, students might argue that avoiding losses is always logical.

  After the game, display class data showing how many points were lost versus gained. Ask students to revisit their strategies and explain how the framing of losses skewed their choices.
