Replication material to solve for Shanker and Wolfe (2021): "Play for the Rich and Work for the Poor?Optimal Saving and Work Hours in the Heterogeneous Agents Neoclassical Growth Model" CEPR discussion paper DP16479

Package solves the incomplete market equilibrium and constrained optima for a Bewley-Aiyagari-Huggett model with labour-leisure choice. The consumer problem is solved efficiently using the Endogenous Grid Method.

Preferred usage solves with X-entropy using MPI

main_mpi.py solves IM and CP using cross entropy across multiple nodes. For example, to solve using N = 420 draws

mpiexec -n 420 python3 -m mpi4py main_mpi.py modelname /results_path

Note all parameter values (inc. grid sizes and number of elite draws for cross entropy etc.) specified in .yml files under /settings
