This chapter refines the model introduced in Chap. 5 by assuming that preferences are represented by a constant relative risk aversion (CRRA) utility function. While keeping the remaining assumptions unchanged, we analyze the implications of this refinement on the Hamilton-Jacobi-Bellman (HJB) equation, the first-order conditions, and the partial differential equation (PDE) governing asset prices. This chapter is based on Cox et al. (Econometrica, 53(2), 385–407 (1985b)).

摘要

This chapter refines the model introduced in Chap. 5 by assuming that preferences are represented by a constant relative risk aversion (CRRA) utility function. While keeping the remaining assumptions unchanged, we analyze the implications of this refinement on the Hamilton-Jacobi-Bellman (HJB) equation, the first-order conditions, and the partial differential equation (PDE) governing asset prices. This chapter is based on Cox et al. (Econometrica, 53(2), 385–407 (1985b)).
