Dynare 6
|
|
|
--------
|
|
|
|
|
|
- Different versions of Dynare are now available as [Docker Containers](https://hub.docker.com/r/dynare/dynare).
|
|
|
- Implementation of the Sequential Monte-Carlo sampler (new value `hssmc` for option `posterior_sampling_method`) as described by Herbst and Schorfheide (JAE, 2014).
|
|
|
|
|
|
- New perfect foresight simulation with expectation errors. In such a scenario, agents make expectation errors, in the sense that the path they had anticipated in period 1 does not realize exactly. More precisely, in some simulation periods, they may receive new information that makes them revise their anticipation for the path of future shocks. Also, under this scenario, it is assumed that agents behave as under perfect foresight, *i.e.* they take their decisions as if there was no uncertainty and they knew exactly the path of future shocks; the new information that they may receive comes as a total surprise to them. Implemented by new `perfect_foresight_with_expectation_errors_setup` and `perfect_foresight_with_expectation_errors_solver` commands, and `shocks(learnt_in=…)`, `mshocks(learnt_in=…)` and `endval(learnt_in=…)` blocks.
|
|
|
|
|
|
- Pruning à la Andreasen et al. (2018) is now available at an arbitrary approximation order when performing stochastic simulations with `stoch_simul` (!2147)
|
|
|
- IRF matching with stochastic simulations:
|
|
|
- Dynare supports both Frequentist (as in Christiano, Eichenbaum, and Evans (2005, JPE)) as well as Bayesian IRF matching approaches (as in Christiano, Trabandt, and Walentin (2010, Handbook)). The core idea of IRF matching is to treat empirical impulse responses (e.g. given from a SVAR or local projection estimation) as data and select model parameters that align the model's IRFs closely with their empirical counterparts. (!2191)
|
|
|
- New options to `method_of_moments` command. (preprocessor!85)
|
|
|
- New blocks `matched_irfs` and `matched_irfs_weights` to specify the values and weights of the empirical impulse response functions. (preprocessor#124)
|
|
|
|
|
|
- New `conditional_likelihood` option to the `estimation` command. When the option is set, instead of using the Kalman filter to evaluate the likelihood, Dynare will evaluate the conditional likelihood based on the first order reduced form of the model, by assuming that the initial state vector is 0 for all the endogenous variables. (b7693c32, f7694208)
|
|
|
- Pruning à la Andreasen et al. (2018) is now available at an arbitrary approximation order when performing stochastic simulations with `stoch_simul` (!2147), and at 3rd order when performing particle filtering (!2071, particles!16, !2045)
|
|
|
|
|
|
- The `estimation` command now accepts the `additional_optimizer_steps` option, to sequentially execute several optimizers when looking for the posterior mode (!2178)
|
|
|
- New `log` option to the `var` statement. In addition to the endogenous variable(s) thus declared, this option also triggers the creation of auxiliary variable(s) equal to the log of the corresponding endogenous variable(s). For example, given a ``var(log) y`` statement, two endogenous will be created (``y`` and ``LOG_y``), and an auxiliary equation linking the two will also be added (equal to ``y = exp(LOG_y)``). Moreover, every occurrence of ``y`` in the model will be replaced by ``exp(LOG_y)``. This option is for example useful when one wants to perform a loglinear approximation of some variable(s) in the context of a first-order stochastic approximation; or when one wants to ensure the variable(s) stay(s) in the definition domain of the function defining the steady state or the dynamic residuals when the nonlinear solver is used. (#349)

- new `model_replace` block to replace equations (preprocessor@1f004584e9c8b2ea5fbda6dd5413b516ce956679)
|
|
|
|
|
|
- :warning: Dynare will not duplicate information stored in `oo_.endo_simul, oo_.exo_simul`, and `oo_.irfs` in the base workspace. New helper functions `send_endogenous_variables_to_workspace`, `send_exogenous_variables_to_workspace`, and `send_irfs_to_workspace` can be used to explicitly request these outputs and to mimic the old behavior (!2229).

|
|
|
|
|

|
|
|
|
|
|
- Steady state homotopy: new option `from_initval_to_endval` option to the `homotopy_setup` block, for easily computing homotopy from initial to terminal steady state (when the former is already computed) (2e3fbfc0408a360dd169c927a5ea38c89f6ff95c)

- Performance improvement to `solve_algo=12` and `solve_algo=14` (which can significantly accelerate the simulation of purely backward/static/forward models)
|
|
|
|
|
|
|
|
|
- dseries:
|
|
|
|
|
|
- The `remove` and `remove_` methods now accept a list of variables (it would previously accept only a single variable) (dseries@b7ca9c3e, c02e5505)
|
|
|
- new `--with-legend` option to the `dplot` command (dseries@44c36549)
|
|
|
|
|
|
- Under the MATLAB Desktop, autocompletion is now available for the `dynare` command and other CLI commands (thanks to Eduard Benet Cerda from MathWorks) (36a2a41e357780d468582c78c4cbb738c5bb4b26)

- Misc
|
|
|
|
|
|
- :warning: New `non_zero` option to `resid` command to restrict display to non-zero residuals (preprocessor@9db21a231c5ab8f8aa26680ffecf3abfcf45bfab, 3d7299c1e490a6813de2b2cb450b738b4c7acdf9); the old syntax `resid(1)` is not supported anymore
|
|
|
- New `display_parameter_values` command to print the parameter values to the command window (!2268).
|
|
|
|
|
|
- The `stack_solve_algo=1` and `stack_solve_algo=6` options were merged. Both are now synonymous, and provide the LBJ algorithm. They work both with and without the `block` and `bytecode` options. Using `stack_solve_algo=1` is now recommended, but `stack_solve_algo=6` is kept for backward compatibility reasons (06f665e231c1a66863612eb75802ff4f0b698c57)
|
|
|
- New `collapse_figures_in_tabgroup` command to dock all figure (!2263)
|
|
|
|
|
|
- Model debugging: the preprocessor now creates files for evaluating separately the left- and right-hand sides of model equations. For a model file called `ramst.mod`, you can call `[lhs,rhs]=ramst.debug.static_resid(y,x,params);` (for the static model) and `[lhs,rhs]=ramst.debug.dynamic_resid(y,x,params,steady_state);` (for the dynamic model), where `y` are the endogenous, `x` the exogenous, `params` the parameters, and `steady_state` is self-explanatory. NB: In the dynamic case, the vector `y` of endogenous must have $3n$ elements where $n$ is the number of endogenous (including auxiliary ones); the first $n$ elements correspond to the lagged values, the middle $n$ elements to the contemporaneous values, and the last $n$ elements to the lead values.

|
|
- When `use_dll` option of the `model` block is set, the preprocessor now takes advantage of parallelization when compiling the MEX files (preprocessor@f6053df7545174885486a457a2253897a1ed4e27, preprocessor@5cf4729ab0790084af0b0a9e9a1062ddefff3401, preprocessor@dd66459e5f2e5c57ea25cb4a0e8709b22ff3195b, preprocessor@3dd40c6c42d82997972e90899da8632a747f5c90)

|
|
|
- New `search` interactive command for listing the equations in which given variable(s) appear (#1886)
|
|
|
- Support for new mathematical primitives: complementary error function (`erfc`), hyperbolic functions (`cosh`, `sinh`, `tanh`, `acosh`, `asinh`, `atanh`) (preprocessor#85, preprocessor@c0ea8d72038cd6c57e48aca26d2d29866848ae0a)
|
|
|
|
|
|
- :warning: the default value of the `mode_compute` option of the `estimation` command has been changed to `5` (it was previously `4`)
|
|
|
- New `last_simulation_period` option to `initval_file` command (see #1838, f5f47cd834049bd5111f23622fb2c68d0e6a619b, preprocessor@ddddf89d9cd8771bb80beb5c44efe53f4734b41f)
|
|
|
|
|
|
- :warning: The `dynare_sensitivity` command has been renamed `sensitivity`. The old name is still accepted, but will trigger a warning (66bc9fd9c2707c787efae797e1976b7052159dc4)
|
|
|
- The `calib_smoother` command now accepts options `nobs` and `heteroskedastic_filter` (see !2110)
|
|
|
|
|
|
- :warning: The `model_info`-command allows to print the block decomposition even if the `block`-option of the `model` has not been used by specifying the new options `block_static` and `block_dynamic`. The old `static`-option of the command is superseded by the `block_static`-option. (45450651 and preprocessor@2fd06811)

- :warning: The default location for the configuration file has changed. On Linux and macOS, the configuration file is searched by default under `dynare/dynare.ini` in the configuration directories defined by the XDG specification (typically `$HOME/.config/dynare/dynare.ini` for the user-specific configuration and `/etc/xdg/dynare/dynare.ini` for the system-wide configuration, the former having precedence over the latter). Under Windows, the configuration file is searched by default in `%APPDATA%\dynare\dynare.ini` (typically `c:\Users\USERNAME\AppData\Roaming\dynare\dynare.ini`) (43b24facb)

- There is now a default value for the global initialization file (`GlobalInitFile` option of the configuration file): the `global_init.m` in the Dynare configuration directory (typically `$HOME/.config/dynare/global_init.m` under Linux and macOS, and `c:\Users\USERNAME\AppData\Roaming\dynare\global_init.m`` under Windows) (43b24facb)
|
|
|
- New `search` interactive command for listing the equations in which given variable(s) appear (#1886)
|
|
|
- :warning: Dynare will not duplicate information stored in `oo_.endo_simul, oo_.exo_simul`, and `oo_.irfs` in the base workspace. New helper functions `send_endogenous_variables_to_workspace`, `send_exogenous_variables_to_workspace`, and `send_irfs_to_workspace` can be used to explicitly request these outputs and to mimic the old behavior (!2229).
|

- :warning: The `dynare_sensitivity` command has been renamed `sensitivity`. The old name is still accepted, but will trigger a warning (66bc9fd9c2707c787efae797e1976b7052159dc4)
|
|
|
|
|
|
- :warning: the `block` option of the `model` block no longer has an effect when used in conjunction with `stoch_simul` or `estimation` commands (8f1a4cb3637fe4936ade877c88e6a120af2b5f24)
|
|

|
|
|
|
|
|
- :warning: a macro-processor variable defined without a value (such as `@#define var` in the `.mod` file or alternatively `-Dvar` on the `dynare` command line) is now assigned the `true` logical value (it was previously assigned `1`) (preprocessor#43)
|
|

|
|
- :warning: `mode_compute` will recursively update the covariance matrix across the `NumberOfMh` Metropolis-Hastings runs, starting with the `InitialCovarianceMatrix` in the first run, instead of computing it from scratch in every Metropolis-Hastings run (e5102eee)
|

- Implementation of the Sequential Monte-Carlo sampler (new value `hssmc` for option `posterior_sampling_method`) as described by Herbst and Schorfheide (JAE, 2014).
|
|
|
|
|
|
- IRF matching with stochastic simulations:
|
|
|
- Dynare supports both Frequentist (as in Christiano, Eichenbaum, and Evans (2005, JPE)) as well as Bayesian IRF matching approaches (as in Christiano, Trabandt, and Walentin (2010, Handbook)). The core idea of IRF matching is to treat empirical impulse responses (e.g. given from a SVAR or local projection estimation) as data and select model parameters that align the model's IRFs closely with their empirical counterparts. (!2191)
|
|
|
- New options to `method_of_moments` command. (preprocessor!85)
|
|
|
- New blocks `matched_irfs` and `matched_irfs_weights` to specify the values and weights of the empirical impulse response functions. (preprocessor#124)
