Richard Thaler - DeveloPassion

# Richard Thaler Richard H. Thaler (born 1945) is an American economist and the principal founder of [[Behavioral Economics]]—the field that integrates psychology into economic theory. He received the Nobel Prize in Economics in 2017 "for his contributions to behavioural economics." His work demonstrated that humans are not the rational "Econs" assumed by traditional economics but "Humans" who make predictable errors. Key concepts he developed or popularized include **mental accounting**, the **endowment effect**, **present bias**, and **[[Nudge theory]]** (with [[Cass Sunstein]]). His 2008 book *Nudge* influenced governments worldwide to create "nudge units" applying behavioral insights to public policy. Thaler is the Charles R. Walgreen Distinguished Service Professor of Behavioral Science and Economics at the University of Chicago Booth School of Business—ironically the home of rational choice theory he challenged. His collaboration with [[Daniel Kahneman]] and [[Amos Tversky]] in the 1970s-80s was foundational, applying their psychological findings to economics. Unlike many academics, Thaler writes accessibly; *Misbehaving* (2015) tells the story of behavioral economics' development with wit and clarity. He famously appeared in the film *The Big Short* (2015), explaining the financial crisis. His work bridges theory and practice, showing how understanding human behavior leads to better policies, products, and decisions. ## Key Concepts ``` ┌─────────────────────────────────────────────────────────────┐ │ THALER'S BEHAVIORAL ECONOMICS │ ├─────────────────────────────────────────────────────────────┤ │ │ │ TRADITIONAL ECONOMICS BEHAVIORAL ECONOMICS │ │ (Homo economicus) (Homo sapiens) │ │ ┌──────────────────────┐ ┌──────────────────────┐ │ │ │ • Rational │ │ • Bounded rationality│ │ │ │ • Self-interested │ │ • Social preferences │ │ │ │ • Unlimited willpower│ │ • Limited willpower │ │ │ │ • Perfect information│ │ • Limited attention │ │ │ │ • Consistent prefs │ │ • Context-dependent │ │ │ └──────────────────────┘ └──────────────────────┘ │ │ │ │ "If you want to encourage people to do something, │ │ make it easy." — Richard Thaler │ │ │ └─────────────────────────────────────────────────────────────┘ ``` ##
