1. Economic principles shape everyday behaviors and decisions

The cost-benefit principle says you should take an action if and only if the extra benefit from taking it is greater than the extra cost.

Rational decision-making. This fundamental economic principle applies to a wide range of everyday situations, from personal choices to business strategies. It explains seemingly puzzling behaviors, such as:

• Why there are Braille dots on drive-up ATM keypads
• Why milk is sold in rectangular containers while soft drinks are in cylindrical cans
• Why 24-hour convenience stores have locks on their doors

Opportunity costs matter. Understanding the true cost of our choices, including what we give up by making them, is crucial for making informed decisions. This concept helps explain phenomena like:

• Why people often fail to recycle aluminum cans in the US but do so at high rates in Brazil
• Why highly talented workers sometimes choose less prestigious jobs

2. Supply and demand govern pricing strategies and market dynamics

Although equally talented workers often earn different salaries, workers tend to be paid in rough proportion to the value they add to their employer's bottom line.

Market forces at work. The interplay of supply and demand explains many pricing strategies and market outcomes, including:

• Why female models earn much more than male models
• Why top earners' salaries have grown faster than average wages
• Why some products are sold at discounts while others maintain high prices

Price discrimination tactics. Businesses often use creative strategies to charge different prices to different customers based on their willingness to pay:

• Offering coupons or early-bird specials
• Charging more for last-minute purchases
• Providing student or senior discounts

3. Individual and group interests often diverge, leading to inefficiencies

Cherries growing in public parks begin to disappear the moment they become just ripe enough that eating them is better than nothing.

Tragedy of the commons. When individual incentives conflict with group interests, inefficient outcomes often result. Examples include:

• Overprescription of antibiotics leading to drug-resistant bacteria
• Overfishing in international waters
• Traffic jams caused by rubbernecking

Collective action problems. Society often develops mechanisms to align individual and group interests:

• Workplace safety regulations
• Mandatory helmet laws in sports
• Environmental protection laws

4. Property rights and regulations balance societal needs and individual freedoms

The laws of private property grant owners considerable, but not absolute, power to decide how their property is used.

Defining ownership. Property rights are crucial for economic development but are not unlimited:

• Adverse possession laws encourage productive use of property
• Eminent domain allows governments to take private property for public use
• Intellectual property laws balance innovation incentives with public access

Regulatory trade-offs. Governments must balance various interests when creating regulations:

• Child safety seat requirements in cars but not on airplanes
• Seat belt requirements in cars but not on school buses
• Bans on talking on handheld phones while driving, but not on eating or drinking

5. Psychological factors influence economic choices and market outcomes

Victoria's Secret offers multimillion-dollar jewel-studded bras that no one ever buys to shift the frame of reference that defines appropriate spending for a gift.

Cognitive biases. Behavioral economics reveals how psychological factors affect decision-making:

• Anchoring effects in pricing strategies
• Availability heuristic in risk perception
• Framing effects in marketing and advertising

Irrational choices. People often make decisions that seem to contradict traditional economic theory:

• Paying more for "fair trade" products
• Tipping in restaurants they'll never visit again
• Donating to charities anonymously

6. International differences in economic behavior reflect varying costs and benefits

Europeans choose smaller engines not because they don't like fast cars but because the financial penalty for large engines is so high.

Cultural adaptations. Many international differences in economic behavior can be explained by varying costs and benefits:

• Higher recycling rates in Brazil due to lower opportunity costs of collecting cans
• Smaller houses in the UK compared to Australia due to higher land prices
• Reserved seating in Asian cinemas due to higher demand and lower incomes

Policy impacts. Government policies and regulations shape economic behavior across countries:

• Higher unemployment rates in Germany due to more generous social benefits
• Smaller car engines in Europe due to higher fuel taxes
• Higher proportion of luxury cars in Singapore due to unique vehicle licensing fees

7. Personal relationships are subject to economic forces and market dynamics

Fitzgerald never reveals the precise details of how Gatsby amassed his fortune. But he leaves little doubt that Gatsby's work was not just morally suspect but well outside the law.

Marriage market dynamics. Economic principles can help explain patterns in dating and marriage:

• Increasing average age at first marriage due to changing costs and benefits
• Rural residents marrying younger than urban dwellers
• Assortative mating based on personal characteristics

Relationship strategies. People often employ economic-like tactics in personal relationships:

• Signaling desirability through coyness
• Investing in personal attributes to increase "market value"
• Making commitments to overcome future temptations

8. Behavioral economics reveals cognitive biases in decision-making

Students who got a ten or less on the wheel reported an average estimate of 25 per cent, while those who got sixty-five or more reported an average estimate of 45 per cent.

Cognitive shortcuts. People often rely on mental shortcuts or heuristics when making decisions:

• Anchoring effect: initial information influences subsequent judgments
• Availability heuristic: easily remembered events seem more frequent
• Framing effect: how choices are presented affects decision-making

Irrational patterns. Behavioral economics identifies systematic deviations from rational choice theory:

• Loss aversion: people are more sensitive to losses than equivalent gains
• Endowment effect: people value things more when they own them
• Present bias: overvaluing immediate rewards compared to future ones

9. Social norms and institutions evolve to address economic challenges

Hockey players routinely empower their leagues to enforce rules requiring helmets, even though they invariably skate without them in the absence of such rules.

Collective solutions. Societies develop norms and institutions to overcome individual-group conflicts:

• Queuing norms to allocate scarce resources fairly
• Tipping customs to incentivize good service
• Professional codes of conduct to maintain industry standards

Adaptive practices. Economic pressures shape social customs and business practices:

• School uniforms to reduce clothing arms races
• First-come, first-served norms on one-lane bridges
• Corporate gift-giving practices to attract and retain employees
