He is a leading theorist in behavioral economics. This field studies how human psychology affects economic decisions. For many years, traditional economics assumed people were perfectly rational. It suggested humans could calculate like computers without emotions. Thaler challenged this view by showing that people often make mistakes. He helped build a bridge between psychology and economic analysis. This work created a rapidly expanding new field of study.

Thaler's research identifies several specific ways that humans behave. One key concept is the endowment effect.

This effect shows that people value things more just because they own them. Even if two items are identical, owners often rate them higher. Another concept is mental accounting. This is how people categorize money into separate mental groups. People might treat a tax refund differently than a regular paycheck. These mental accounts change how individuals budget, save, and spend.

He also studied myopic loss aversion, or MLA. This occurs when investors are guided by a fear of loss. This fear happens over a short time horizon. MLA can lead to the equity premium puzzle. This means people might underinvest in stocks even when they perform well. Thaler also explored choice architecture. This refers to how the presentation of options influences decisions. By organizing choices, experts can guide people toward better outcomes. This process is often called a "nudge."

Thaler advocates for a concept called libertarian paternalism. This idea suggests using nudges to help people make better decisions. These nudges should not take away a person's freedom. A common example is automatic enrollment in retirement savings plans. Most employees stay enrolled because it is the default option. However, they still have the freedom to opt out. Thaler and Cass Sunstein also discussed "sludge" in their work. Sludge is any friction that makes it harder to reach a good outcome. Examples include difficult subscription cancellations or opaque pricing models.

Thaler's academic journey began in New Jersey. He was born in East Orange in 1945. He earned his B.A. from Case Western Reserve University in 1967. He later received his Ph.D. from the University of Rochester in 1974. His thesis focused on the value of saving a life. He taught at the University of Rochester before moving to Cornell University. At Cornell, he founded the Center for Behavioral Economics and Decision Research in 1989. In 1995, he joined the University of Chicago Booth School of Business.

His contributions have earned him many prestigious honors. In 2015, he served as president of the American Economic Association. He was elected to the National Academy of Sciences in 2018. Most notably, he won the Nobel Memorial Prize in Economic Sciences in 2017. The Royal Swedish Academy of Sciences praised his empirical findings. They noted his insights were instrumental to the field of behavioral economics. His work helps explain why people often make choices that seem puzzling.

Thaler has shared his ideas through many books and columns. He wrote "Misbehaving," which covers the history of behavioral economics. He also co-authored "Nudge" with Cass Sunstein in 2008. He wrote a regular column titled "Anomalies" in the Journal of Economic Perspectives. He has also discussed economic solutions for modern problems. For example, he advocates for a carbon tax to help the planet. He believes raising the price of carbon will lead to lower emissions. His work continues to connect human behavior to global economic systems.
