The book "S-shaped Utility Functions and the Puzzles of the Financial Market" offers a comprehensive analysis of S-shaped utility functions and their application in financial markets. Through detailed statistical analyses and analytical calculations, the significance of these functions for understanding risk and consumer behavior is emphasized. Instead of focusing on the relative risk aversion of a representative consumer, the work examines the average risk aversion of consumers, leading to more stable and lower values. This approach allows for better modeling of the risk-return relationship and provides valuable insights into behavioral economics. Furthermore, the role of oil price shocks as a key factor in the turbulence of the American financial market in the 20th century is highlighted, which is also significant for geopolitical and war analytical considerations.
