Quick vs Benchmark vs More Precise (For + Inf + Borr + Save DP)
back to Fan's Dynamic Assets Repository Table of Content.
Testing the ff_abz_fibs_vf_vecsv program for solving the savings and borrowing dynamic programming problem.
Computational speed is determined by the number of asset and shock grid points. Here we run the model with quick, benchmark and more precise simulations with increasing grid points for shocks and asset.
- quick: fast run
- benchmark: default as set in ffs_abz_fibs_set_default_param
- more precise: increase grid count for shocks and asset
@seealso
- BORROW: borrow and default small grid testing: ff_abz_fibs_vf_vecsv_default_small
- BORROW: borrow and default large grid testing: ff_abz_fibs_vf_vecsv_default_large
- PRECISION: borr + save quick vs benchmark testing: fsi_abz_fibs_vf_vecsv_main
- PRECISION: borr + save asset grid count testing: fsi_abz_fibs_vf_vecsv_a_n
- PRECISION: borr + save shock grid count testing: fsi_abz_fibs_vf_vecsv_z_n
