Krusell and smith
WebKrusell and Smith (1998) consider a model in which employment risk is not fully insurable because of borrowing constraints and missing insurance markets. They show that in this environment the model satis–es the "approximate aggregation" property, that is, the mean of the capital stock is a su¢ cient statistic to predict next period™s prices WebCode for the Krusell--Smith model.

Surprisingly, approximate aggregation does not persist in the Aiyagari-Bewley model when a sufficiently high but not unrealistic unem-ployment benefit is introduced. Furthermore, the Krusell-Smith algorithm fails to converge in that case which confirms the failure of approximate aggregation.

While this Krusell and Smith heterogeneity model (KS-hetero as we call it in our comparisons below) also matches the wealth distribution better than their model without heterogeneity (KS below), it does not increase the aggregate MPC nearly enough to match the microeconomic evidence—only to around 010. In contrast to our flight ticket booking to singaporeWebthe Krusell/Smith approximation has the flavor of a “bounded-rationality” solution of the model, the outcome of the method presented here cannot be interpreted in this way.
