摘要

This chapter describes the second approach to solving the dynamic optimization problem of an agent in continuous-time asset pricing theory: the martingale approach. This approach exploits the martingale characteristic of asset prices to solve dynamic models. This chapter provides a detailed explanation of this approach and compares it to the dynamic programming approach.
