1. What Is Behavioral Economics?

(1) Definition

• Behavioral economics studies human decision-making at the intersection of psychology, sociology, and economics.
• It emphasizes that humans are not always rational, and emotions, cognitive biases, and social influences significantly impact decisions.

(2) Differences from Traditional Economics

• Traditional Economics: Assumes humans act rationally to maximize utility.
• Behavioral Economics: Recognizes limited rationality, with actions often driven by emotions or habits.

2. Key Theories in Behavioral Economics

(1) Bounded Rationality

• People lack the time or cognitive ability to analyze all information, leading to incomplete decisions.
• Example: Buying a product based solely on a discount without reviewing all specifications.

(2) Anchoring Effect

• Initial information or numbers heavily influence decisions.
• Example: Buying an item just because it’s labeled as “50% off” from a high original price.

(3) Prospect Theory

• People perceive losses more intensely than equivalent gains, leading to a loss aversion bias.
• Example: Avoiding a $10 loss feels more critical than gaining $10.

(4) Fundamental Attribution Error

• Attributing others’ actions to their personality while attributing our own actions to external circumstances.
• Example: Thinking someone is lazy for being late while blaming traffic when you are late.

(5) Social Comparison

• People often make economic decisions based on comparisons with others.
• Example: Feeling the need to buy a new car because a friend just bought one.

3. Real-Life Applications of Behavioral Economics

(1) Understanding Spending Patterns

• Discounts often exploit the anchoring effect and loss aversion.
• TIP: Pause and assess whether you truly need the item before making a purchase.

(2) Improving Saving Habits

• People tend to prioritize present consumption over future savings.
• TIP: Automate savings to simplify the decision-making process.

(3) Encouraging Healthy Choices

• Product placement and framing can nudge consumers toward healthier decisions.
• Example: Placing healthier food options at eye level in grocery stores.

(4) Enhancing Investment Decisions

• Excessive loss aversion can cause missed opportunities in investments.
• TIP: Balance risks and rewards with a long-term perspective.

(5) Designing Public Policies

• Behavioral economics principles are used in policy design.
• Example: Automatically enrolling employees in pension plans to increase participation rates.
