Behavioral Economics: Crash Course Economics #27
TLDRThe video discusses behavioral economics, a field blending economics and psychology to understand irrational elements of decision-making. It emerged to address shortcomings of classical economics in predicting human behavior. Concepts like bounded rationality, perceptual biases, emotional factors, and loss aversion are explored through experiments showing people don't always make optimal, utility-maximizing choices. Applications in marketing, finance, policymaking are noted. Ultimately, behavioral economics provides a realistic perspective on decision-making by accounting for emotion and irrationality alongside classical economic theory.
Takeaways
- 😀 Behavioral economics studies how psychological, social and emotional factors influence economic decision making
- 💡 People often act irrationally and make decisions based on limited information
- 📈 Prices and marketing can manipulate perceptions and impact demand
- 🔎 Investors don't always act logically and their passion can drive bubbles
- 💰 In experiments, players surprisingly reject uneven money splits, contradicting classical theory
- 😕 The way choices are framed influences decisions more than expected
- 👍 'Nudge theory' gently encourages better choices without restricting options
- 😨 People tend to be loss averse and strongly avoid losing money
- 🎯 Small losses incentivized workers better than comparable bonuses in an experiment
- 💡 Overall, accounting for human irrationality and psychology gives a realistic view of decisions
Q & A
What is behavioral economics?
-Behavioral economics is a subfield of economics that focuses on the psychological, social, and emotional factors that influence decision-making.
How does bounded rationality affect economic models?
-Bounded rationality means there are limits on information, time, and abilities that might prevent people from seeking the best possible outcome. This can cause them to make decisions that don't follow economic laws like the law of demand.
How can pricing influence perceptions of quality?
-Studies have shown that people perceive higher prices as signals of higher quality. So higher prices can actually increase demand by changing perceptions of a product's quality.
How do emotions like exuberance contribute to economic bubbles?
-Bubbles happen when investors become irrationally exuberant and are driven by emotions rather than logic. This enthusiasm can inflate asset prices beyond their real values.
What is the ultimatum game and what does it demonstrate?
-The ultimatum game shows that people reject unequal money splits even though it is economically irrational. This contradicts classical theory and shows that fairness concerns can override pure financial gain.
What is the framing effect?
-The framing effect means that people's preferences can change depending on how options are presented. Classically economics assumes framing shouldn't matter, but psychology says it does.
How do nudges work?
-Nudges encourage certain behaviors without restricting choices. They work by understanding psychology and designing environments accordingly, like putting healthy foods at eye level.
How does loss aversion affect risk?
-Loss aversion means losses hurt more than equivalent gains feel good. To avoid potential losses, people may choose safer options over statistically better bets.
How was loss aversion used to reduce plastic bag use?
-Grocery stores found that charging a small tax on bags worked better to reduce use than offering a bonus for bringing reusable bags. People are more motivated to avoid losing money.
How can behavioral economics lead to better policymaking?
-By accounting for actual human behavior, biases, and motivations, governments can design more effective policies, incentives, and interventions to influence decisions.
Outlines
😊 Introducing Behavioral Economics
Jacob and Adriene introduce the concept of behavioral economics, which blends economics and psychology to understand irrational elements of human decision making. They explain how most people are rational but there are limits, using an ice cream pricing example. They also discuss how perceptions influence actions in areas like wine tasting and investing.
😮 Explaining Human Irrationality
Jacob discusses experiments like the ultimatum game that demonstrate irrational human behavior that contradicts classical economics. Adriene then explains cognitive biases like framing effects and how businesses use psychological pricing. She also introduces nudge theory for gently encouraging desired choices.
😬 Examining Attitudes Toward Risk
Jacob and Adriene explore how behavioral economics studies risk and loss aversion - people's tendency to strongly avoid losses. They give examples of loss aversion at work, like grocery store plastic bag policies and employee bonus structures.

Highlights
Behavioral economics focuses on psychological, social, and emotional factors that influence decision-making.
Bounded rationality means limits on information, time, and abilities might prevent people from seeking the best possible outcome.
Prices send signals, and there's science on how prices change perception of quality.
Investors can become irrationally exuberant, driven by what Keynes called "animal spirits" rather than logic.
The ultimatum game shows people aren't always as predictable as economists suggest.
Framing effects show that how options are presented can influence decisions, contradicting classical economics.
Nudge theory encourages desired behaviors without restricting choices.
People are generally loss averse - losses are more painful than equivalent gains are pleasurable.
A tax on plastic bags was more effective than a bonus for reusable bags, demonstrating loss aversion.
Workers performed better when given a bonus upfront that they may have to repay, showing power of loss aversion.
Accounting for emotion gives a realistic view of actual human behavior.
Behavioral economics helps explain phenomena like bubbles and improves policymaking.
Behavioral economics adds complexity and nuance versus classical economic theories.
Prices ending in .99 are a type of psychological pricing to signal a good deal.
High-end retailers may use whole dollar prices to signal quality of goods.
