Measures: Absolute Risk Aversion (ARA) and Relative Risk Aversion (RRA).
Application: Insurance markets and lotteries. The book uses simple two-state examples (e.g., "accident" vs. "no accident") to clarify complex integrals.
1. Production Functions
Key Concepts: Rationality, Preference Relations (Strict, Weak, Indifference), Utility Functions as representations of preferences.
Intuitive Hook: Why do we assume "more is better" (monotonicity) and "averages are better than extremes" (convexity)?
Focus Area: Pay close attention to the Marginal Rate of Substitution (MRS). The book excels at explaining the geometry of indifference curves.
Common Examples: Comparing Cobb-Douglas (balanced preferences) vs. Perfect Substitutes/Complements.
