A General Equilibrium Model with CRRA Preferences and k State Variables
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)).
