Kreps A Course In Microeconomic Theory Solutions [2021] -

• Chapter 2 (Expected Utility Theory): Problem 2.7 (The Allais Paradox). Students need the formal proof of why expected utility fails here. Look for solutions that reference "mixture sets" and "independence axiom."
• Chapter 4 (Preferences Under Uncertainty): Problem 4.3 (Subjective Probability). The solution requires proving that preferences over acts imply a unique probability measure. This is notoriously tricky.
• Chapter 8 (Game Theory): Problem 8.5 (Correlated Equilibrium vs. Nash). The solution involves linear algebra and convex polytopes. Most unofficial solutions get the dimension wrong.
• Chapter 12 (General Equilibrium): Problem 12.2 (Existence of Walrasian Equilibrium). You will need the Brouwer Fixed Point Theorem. The solution is less about math and more about the topological argument.
