WebIn their seminal paper on introducing heterogeneity into dynamic stochastic general equilibrium (DSGE) models, Krusell and Smith (1998) note that it is possible to now use ‘equilibrium models to analyse the interrelation between business cycles, inequality and economic policy’ (p. 890). WebBut solving for a law of motion that moves any initial distribution forward one period and that is consistent with the optimal policy function is a daunting task. In their 1998 paper, “Income and Wealth Heterogeneity in the Macroeconomy,” Krusell and Smith (KS from now on) proposed a way to work around this problem and include aggregate risk. in images of cayden stoutWebI Krusell, Mukoyama, and Smith (2011). \Asset Prices in a Huggett Economy," Journal of Economic Theory 146, 812-844.

WebKrusell-Smith Algorithm ¶ The best-known solution algorithm is the Krusell-Smith algorithm. [1] The main idea is to approximate the distribution of wealth with a small number of moments, e.g. it’s mean K, and specify a reduced-form law of motion for these moments.
