- Issues
- Add a contraction-aware stopping rule and a convergence report with the target levels of market resources
- GenIncProcess-family simulation applies PermGroFac twice (simulated pLvl grows at PermGroFac**2)
- Apply PermGroFac once in GenIncProcess-family simulation
- Cut repeated work and dead code from the test suite
- Add HARK.stationary: plug-in methods for solving infinite-horizon problems directly, with Anderson mixing first
- Add check_flow_budget and aggregate_SSJs beside make_basic_SSJ: the household flow-budget identity as the acceptance test, and aggregation over types
- quiet=True makes solve() fail for infinite-horizon IndShockConsumerType: post_solve needs the conditions that pre_solve skipped
- The default tolerance stops backward induction while consumption is still 1e-4 to 1e-3 from the fixed point
- Bugs outside log utility found while fixing CRRA=1 (#1587)
- Add a ghost-run option to make_basic_SSJ: difference against an unperturbed finite horizon, not the steady state
