"HETEROGENEITY, AGGREGATE UNCERTAINTY AND THE SHORT-TERM INTEREST RATE"

In this paper, I solve heterogenous agents models using the parameterized expectations algorithm (PEA) and the policy function iterations algorithm (PFI). The problem in solving these models is that the wealth distribution belongs to the set of state variables. I solve this problem by approximating the distribution with a limited set of moments or percentiles.

- PEA program with percentiles from section 3.
- PEA program with moments from section 3.
- PFI program from section 3.
- Simulation PFI program from section 3.
- PEA program from section 4.
