|
* Various problems with perfect foresight simulations in combination with `block` and/or `bytecode` options:
|
|
* The `contemp_reduced_form`-option of the `sbvar`-command is broken (bug not yet fixed, see #1716)
|
|
+ Simulation with `bytecode` and `stack_solve_algo=4` of *linear* “Solve two boundaries simple/complete” blocks can give incorrect results (fixed in 65e18fe8834b31a885667e0e498e3a2ff0f1f47a)
|
|
|
|
+ Simulation with `bytecode` and `stack_solve_algo=1` may fail to converge (fixed in 67a003aa730e59f7b254353ca124909d69dcaaca)
|
|
|
|
+ Simulation with `block` (but without `bytecode`) of blocks of type “Solve two boundaries simple/complete” gives wrong results in the last simulation period (fixed in 0147faad5f03cc641fd22d3e5733d4862964ef0b)
|
|
|
|
+ Simulation with `bytecode` and `block` of *linear* “Solve forward simple/complete” blocks will give incorrect results (fixed in 863fa2de1c04d2a33aef042adacdb78dae4d0ae1)
|
|
|
|
+ Simulation with block decomposition (but without `bytecode` option) will crash or give incorrect results if there are blocks of type “Solve forward/backward simple/complete” (fixed in fa7b331cf4143816a6565e3b5075cc3b10ba879d)
|
|
|
|
+ Simulation with `bytecode` and `block` options and `stack_solve_algo={0,1,4}` will crash or give incorrect results if there are blocks of type “Solve forward/backward complete” (fixed in cdb4f872b24dd811c6053026695d342e05d2b1f9 and 188df7711d4f4a704d7768a61ce70d492cfec9a3)
|
|
|
|
+ Simulation with `block` (but without `bytecode`) gives incorrect results if a block of type “Solve backward simple/complete” is in the model (purely forward equations that cannot be simply evaluated) (fixed in bb793d87cc7dc35fe4fd4767322c2f7b57788eb9)
|
|
|
|
+ Simulation with `block` of nonlinear blocks of type “Solve forward/backward simple” could give incorrect results (fixed in preprocessor@7fff8b34064a98770151b23e45e52c19bfa40569)
|
|
|
|
+ Simulation with `bytecode` and `block` of blocks of type “Solve backward/forward” that follow a “Solve two boundaries” block (in the sense of the dependency graph) could give incorrect results (fixed in 96fb676be757725830d354e2d92cc3a947b5ea31)
|
|
|
|
+ The convergence criterion in simulations with `block` (without `bytecode`) is incorrect: the value of the `tolf` option from the `steady` command is used instead of the value of `tolf` option from the `perfect_foresight_solver` command (fixed in dd1ec10ec897d9271b286c7b3b001237938b1111)
|
|
|
|
* Various problems with steady state computation in combination with `block` and `bytecode` options:
|
|
|
|
+ Steady state computation with `bytecode` and `block` could fail if some equations are marked `[static]` (if temporary terms were created for the derivatives) (fixed in preprocessor@b78ac1d31fd27b8cc89ac2162d58d029821f9af1 and 8f5815d01d3604494f4a0bffc5f92d842972b844)
|
|
|
|
+ Steady state computation with `bytecode` and `block`, and `solve_algo` ⩽ 4 or ⩾ 9 can needlessly fail
|
|
|
|
+ Steady state computation with `bytecode` and `block` options and `solve_algo=6` will crash or give incorrect results if there are blocks of type “Solve forward/backward complete” (fixed in 188df7711d4f4a704d7768a61ce70d492cfec9a3)
|
|
|
|
* The `check` command will crash or give incorrect results when using block decomposition and a block of type “Solve backward complete” is in the model (several interrelated purely forward equations) (fixed in dd34554c4e23a12159388d54fe304698c4d64ca5)
|
|
|
|
* The options `static` and `incidence` of the `model_info` command do not work as advertised in the reference manual (fixed in 685598c6e2690cfbc4e677cd2148387716ef8243 and preprocessor@7df67819821ac5946e1b4ace3e974752ce533827)
|
|
|
|
* Various problems with Method of Moments:
|
|
|
|
+ It will crash if no `matched_moments`-block is present (bug fixed, see !1997)
|
|
|
|
+ It will always load the full range of the first Excel sheet instead of the `xls_range` of the specified `xls_sheet` (bug fixed in 176baa22)
|
|
|
|
+ It may crash during steady state finding due to `options_.verbosity` being unset (bug fixed in https://git.dynare.org/Dynare/dynare/-/commit/05519aaaa10bead1eca59738f1c4517ac362d6a8)
|
|
|
|
+ SMM will crash if a parameter draw triggers an error during `additional_optimizer_steps = 13` (bug fixed, see !1998)
|
|
|
|
+ The `debug`-option can not be passed to the command (bug fixed in f3bf8fb8)
|
|
|
|
* The `posterior_sampler_options`-option `scale_file` does not correctly load the scale (bug fixed, see !1999)
|
|
|
|
* `moments_varendo` may crash for large models (bug fixed in 28536314)
|
|
|
|
* `resid` will not show `name`-tags when using `ramsey` (bug not yet fixed, see https://git.dynare.org/Dynare/dynare/-/merge_requests/2017)
|
|
|
|
* Occbin simulations will not work if there is only a surprise shock in the first period (bug fixed in 3b592534)
|
|
|
|
* The Liu & West auxiliary particle filter may enter infinite loops (bug fixed in https://git.dynare.org/Dynare/particles/-/commit/e5a76884332e9ebc608aa50f1abf9ca9c7d0d35a)
|
|
|
|
* The `contemp_reduced_form`-option of the `sbvar`-command is broken (bug not yet fixed, see https://git.dynare.org/Dynare/dynare/-/issues/1716)
|
|
|
|
* Forecasts are only based on the DSGE-model, not the DSGE-VAR (bug not yet fixed; see #819)
