WebHeterogeneous-agent neoclassical model (HANC) studied by Krusell and Smith (1998) has savings through capital. This model has a remarkable feature of approximate aggregation: the mean of wealth distribution can be accurately predicted with the mean of past wealth distribution.

WebThis paper proposes a novel method to compute the simulation part of the Krusell-Smith (1997, 1998) algorithm when the agents can trade in more than one asset (for example, capital and bonds). The Krusell-Smith algorithm is used to solve general equilibrium models with both aggregate and uninsurable idiosyncratic risk and can be used to solve WebThis method was rst proposed by Krusell and Smith (1998), and it has been successfully applied to a wide variety of problems. Notable examples include the pricing and allocation of risky and safe assets (Krusell and Smith (1997), Pijoan-Mas (2007) and Storesletten et al. (2007)), the magnitude of welfare costs
