Richard Thaler's Anomalies: The New Rationality of Capitalism

This article provides an in-depth analysis of the work of Richard Thaler, who challenged the foundations of classical economics based on the Homo oeconomicus model. The text examines how systematic cognitive biases and market anomalies—such as the winner's curse and preference reversals—force a redefinition of rationality in capitalism. The author guides the reader through the psychological mechanisms of decision-making, from mental accounting to the influence of investor sentiment on arbitrage. The work sheds new light on the social and normative dimensions of economics, considering issues of fairness and cooperation in market games. This is a crucial work for those seeking to understand why the mathematical elegance of traditional models often fails when confronted with real-world human behavior in the marketplace.
