For years, modern economics treated rationality as an axiom, creating a mathematically elegant but unrealistic model of homo oeconomicus. Richard Thaler challenged this vision by describing anomalies—behaviors that are errors from the perspective of classical theory, yet form the foundation of human action. This article analyzes how these discoveries change our understanding of markets, law, and culture, from tech negotiations in Israel to corporate structures in France. Readers will learn why we systematically overpay at auctions and how choice architecture affects our savings.
Homo Oeconomicus: The Fiction of Perfect Rationality
The homo oeconomicus model is a mathematical construct that fails in the real world because it ignores human emotions and cognitive biases. Thaler proves that markets are not arenas of pure calculation, but spaces where institutions learn to exploit our regular irrationalities.
Preference Reversal Undermines Choice Consistency
The logical paradox lies in a decision-maker preferring option A but valuing B more highly. Such inconsistency allows for the creation of a money pump—transactions that systematically drain an individual's capital without providing any benefit in return. This proves that preferences are not fixed but are constructed during the decision-making process.

Frequently Asked Questions
What are Richard Thaler's anomalies in the context of contemporary capitalism?
These are systematic departures from the rational choice model, which demonstrate that human market decisions are shaped by emotions, social norms, and cognitive biases.
Why does the phenomenon of preference reversal undermine the foundations of classical economics?
It proves that preferences are not static but constructed in the decision-making process, which allows for the systematic draining of wealth from supposedly rational individuals.
What is the winner's curse in tender processes?
It is based on the fact that winning an auction of uncertain value often means that the winner greatly overestimated the value of the item and, as a result, overpaid for it.
Do financial markets always correct irrational asset valuations?
No, violations of the law of one price can last a long time because arbitrage is risky, and investor sentiment and technical constraints block a return to equilibrium.
How do norms of fairness and reciprocity influence economic behavior?
People often reject materially advantageous offers if they perceive them as unfair, prioritizing dignity and social reciprocity over pure material gain.
