摘要

This paper compares numerical solutions to the model of Krusell and Smith [1998. Income and wealth heterogeneity in the macroeconomy. Journal of Political Economy 106, 867-896] generated by different algorithms. The algorithms have very similar implications for the correlations between different variables. Larger differences are observed for (ⅰ) the unconditional means and standard deviations of individual variables, (ⅱ) the behavior of individual agents during particularly bad times, (ⅲ) the volatility of the per capita capital stock, and (ⅳ) the behavior of the higher-order moments of the cross-sectional distribution. For example, the two algorithms that differ the most from each other generate individual consumption series that have an average (maximum) difference of 1.63% (11.4%).
