This page documents the changes between Dynare versions (including the unstable one). For previous versions of Dynare, please read the dedicated frozen page on the DynareWiki.
Dynare 4.7 (unstable)

New Method of Moments toolbox:
method_of_moments
command (!1750 (merged)) andmatched_moments
block (preprocessor!23 (merged)) that provide functionality to estimate parameters by (i) Generalized Method of Moments (GMM) up to 3rdorder pruned perturbation approximation or (ii) Simulated Method of Moments (SMM) up to any perturbation approximation order. Toolbox is inspired by replication codes accompanied to Andreasen et al. (2018), Born and Pfeifer (2014), and Mutschler (2018). 
performance optimization to pruned state space system and lyapunov solvers (!1749 (merged), !1745 (merged), #1737 (closed))

stoch_simul
now supports theoretical moments atorder=3
withpruning
(dfc73576) and will report second moments based on the pruned state space if thepruning
option is set (4cf9f7d1) 
discretionary_policy
is now able to solve nonlinear models (it will then use their firstorder approximation, and the analytical steady state must be provided) (!1792 (merged)) 
evaluate_planner_objective
now works with 2nd order approximation (!1828 (merged)) 
Option
block
ofmodel
can now be used in conjunction withuse_dll

New nonlinear least squares optimizer based on
lsqnonlin
for computing the mode (available undermode_compute=13
) 
Options
block
andbytecode
ofmodel
can now be used in conjunction with modellocal variables (variables declared with a poundsign #) (#1243 (closed)) 
Macroprocessor: variables can be defined without a value (they are assigned integer 1) (preprocessor#43)

New option
mh_tune_guess
for setting the initial value formh_tune_jscale
(!1717 (closed)) 
New block
filter_initial_state
for setting the initial condition of the Kalman filter/smoother (7c8f4867) 
New option
schur_vec_tol
to theidentification
command, for setting the tolerance level used to find nonstationary variables in Schur decomposition of the transition matrix (!1794 (merged)) 
New
notime
option to thedynare
command (preprocessor@27a8b3b7) 
Refactoring of
histval_file
andinitval_file
(#1671 (closed)) 
dseries now support biannual (dseries!37 (merged)) and daily (dseries@1b897b37) frequency data

dseries can now import data from DBnomics, via the dbnomics/mdbnomics> plugin (dseries#44 (closed)). Note that this does not yet work under Octave (dbnomics/mdbnomics#10). For the time being, the DBnomics plugin must be installed separately.

routines for converting between time series frequencies (e.g. daily to monthly) have been added to dseries

the
use_dll
option can now directly be given to thedynare
command (a9fea692) 
when compiling from source, it is no longer necessary to pass the
MATLAB_VERSION
version to the configure script; the version is now automatically detected 
In deterministic models, exogenous variables with lead/lags are now replaced by auxiliary variables. This brings those models in line with the transformation done on stochastic models. However note that transformation is still not exactly the same between the two classes of models, because there is no need to take into account the Jensen inequality on the latter. In deterministic models, there is a onetoone mapping between exogenous with lead/lags and auxiliaries, while in stochastic models, an auxiliary endo may correspond to a more complex nonlinear expression (preprocessor@9bca65c7)

When using the
loglinear
option, the output from Dynare now clearly shows that the results reported concern the log of the original variable (!1796 (merged)) 
Modellocal variables are now substituted out as part of the various model transformations. This means that they will no longer appear in LaTeX or in JSON files (for the latter, they are still visible with
json=parse
orjson=check
) 
The total computing time of a run is now saved to
oo_.time
(preprocessor@c79ae5d4) 
⚠ minimal required MATLAB version is now R2014a (8.3) (#1713 (closed)) 
⚠ 32bit support has been dropped under Windows (#1713 (closed)) 
⚠ the preprocessor binary has been renamed todynarepreprocessor
, and is now located in a dedicatedpreprocessor
subdirectory 
⚠ thedynare
command no longer acceptsoutput=dynamic
andoutput=first
(those options actually had no effect)
Dynare 4.6

Stochastic simulations

The perturbation method is now available at an arbitrary approximation order. In other words, the
order
option ofstoch_simul
accepts an arbitrary positive integer (of course, up to some modelspecific computational limit). (#217 (closed)) 
New option
filtered_theoretical_moments_grid
ofstoch_simul
, that supersedeshp_ngrid
.


Estimation

Nonlinear estimation is now also available at an arbitrary approximation order. In other words, the
order
option ofestimation
accepts an arbitrary positive integer (of course, up to some modelspecific computational limit). (#1673 (closed)) 
Various improvements to particle filters.

It is now possible to estimate models under optimal policy (see below).

Variance decomposition of observables now accounts for measurement error. (#1486 (closed))

New option
mh_tune_jscale
ofestimation
command for tuning the scale parameter of the proposal distribution of the Random Walk Metropolis Hastings. 
Added debugging info when parameters take a
NaN
orInf
value. (!1538 (closed)) 
Option
mode_compute=1
is now available under Octave.


Perfect foresight and extended path

A significant speed improvement should be noted on large models (when neither
bytecode
norblock
option is used). The stacked problem is now constructed using a dedicated machinecompiled library that greatly speeds up the process (in particular, the time spent in that step can become negligible when theuse_dll
option is used). 
New options
print
andnoprint
ofperfect_foresight_solver
command. (#1647 (closed)) 
Option
stack_solve_algo=2
is now available under Octave.


Steady state
 Option
solve_algo=7
is now available under Octave.
 Option

Optimal policy

The
ramsey_policy
command is now deprecated. It is superseded by successive calls toramsey_model
,stoch_simul
, andevaluate_planner_objective
(in this order). (#1678 (closed)) 
It is now possible to estimate a model under optimal policy (either Ramsey or discretionary) by running the
estimation
command after eitherramsey_model
ordiscretionary_policy
. It is however not yet possible to estimate parameters that appear in the discount factor of the social planner. (#1173) 
Discretionary policy returns a more informative error message when the objective has nonzero derivatives with respect to some variables. (!1468 (merged))


Identification (!1648 (merged), !1689 (merged), !1683 (merged), !1711 (merged))

Added minimal system identification check of Komunjer and Ng (2011).

Added spectrum identification check of Qu and Tkachenko (2012).

Identification is now also available for approximation orders 2 and 3 with either analytical or numerical parameter derivatives. The relevant moments and spectrum are computed from the pruned state space system as in Mutschler (2015).

All tests (moments, spectrum, minimal system, strength) can be turned off.

More numerical options can be changed by the user.

Improved printing and storage (same folder) of results.


Sensitivity analysis

New
diffuse_filter
option to thedynare_sensitivity
command. (!1562 (merged)) 
Arbitrary expressions can now be passed for the interval boundaries in
irf_calibration
andmoment_calibration
.⚠ This breaks the previous syntax, requiring that the lower/upper bounds be separated by commas. (preprocessor#12 (closed))


Forecasting and smoothing

In
conditional_forecast_paths
, it is no longer required that all constrained paths be of the same length. There may now be a different number of controlled variables at each period. In that case, the order of declaration of endogenous controlled variables and ofcontrolled_varexo
matters: if the second endogenous variable is controlled for less periods than the first one, the secondcontrolled_varexo
isn't set for the last periods. (#699 (closed)) 
New option
parameter_set
to thecalib_smoother
command (#1477 (closed)) 
⚠ The results ofconditional_forecast
command is now saved inoo_
(used to be in a file; see #1672 (closed))


Shock decomposition

Added
fast_realtime
option to real time shock decomposition (deactivated by default, runs the smoother only twice: once for the last insample and once for the last outofsample data point) (!1563 (closed)) and (!1552 (closed)) 
New
diff
,flip
,max_nrows
,plot_init_date
andplot_end_date
options toplot_shock_decomposition
(#1649 (closed), !1655 (merged), 74e7c12d) 
New
initial_decomposition_decomposition
command, for computing and plotting the decomposition of the effect of smoothed initial conditions of state variables (#1586 (closed)) 
New
squeeze_shock_decomposition
command, for removing decompositions of variables that are not of interest (!1655 (merged)) 
New
with_epilogue
option (common toshock_decomposition
,realtime_shock_decomposition
andinitial_condition_decomposition
) (!1688 (merged)) 
New
init2shocks
block to attribute initial conditions to shocks (#1650 (closed))


Macro processor

New object types: real (supersedes integers), boolean (distinct from integers), tuple, userdefined function.

New operators: various mathematical functions, set operations on arrays (union, intersection, difference, cartesian power and product), type checking and conversion.

Added support for comprehensions (e.g. the set containing the squares of all even numbers between 1 and 5 can be constructed with
[ i^2 for i in 1:5 when mod(i,2) == 0]
). 
Userdefined functions can be declared using the
@#define
operator (e.g.@#define f(x) = 2*x^2+3*x+5
). 
@#elseif
clauses are now supported in conditional statements. 
@#for
loops can iterate over several variables at the same time (e.g.@#for (i,j) in X
, whereX
is an array containing tuples of size 2). 
Added the possibility to exclude some elements when iterating over
@#for
loops (e.g.@#for i in 1:5 when mod(i,2) == 0
iterates over all even numbers between 1 and 5). 
A
defined()
function allows testing whether macro variables have been defined. 
Empty arrays (with the
[]
syntax) are now possible (#707 (closed)). 
Arrays of arrays are now supported.

New macro directives
@#echomacrovars
and@#echomacrovars(save)
for displaying or saving the values of all macrovariables. (#1564 (closed)) 
Inline comments are now supported.

⚠ All division operations are now done with doubles (as opposed to integers). To achieve the old functionality, use the newfloor
operator. 
⚠ Colon syntax used to require braces around it to create an array (e.g.[1:3]
would create[1,2,3]
). Now this is not necessary (1:3
creates[1,2,3]
while[1:3]
would create[[1,2,3]]
). 
⚠ Previously, printing a boolean would print1
or0
. Now, it printstrue
orfalse
. To achieve the old functionality, you must cast it to a real, e.g.@{(real)(1!=0)}
.


LaTeX output

New command
write_latex_steady_state_model
. (#1496 (closed)) 
New option
planner_discount_latex_name
oframsey_model
anddiscretionary_policy
. (#1686 (closed)) 
New command
model_local_variable
command for assigning a LaTeX name to modellocal variables. (#563 (closed)) 
The
write_latex_static_model
andwrite_latex_original_model
commands now support thewrite_equation_tags
option. (#1431 (closed))


Compilation of the model (
use_dll
option) made easier and faster
Under Windows, it is no longer necessary to manually install the compiler, since the latter is now shipped by the Dynare installer.

Under macOS, the Dynare installer now automatically downloads and installs the compiler.

It is no longer necessary to configure MATLAB to let it know where the compiler is, since the compilation is now done by the preprocessor.

The compilation phase is now faster on large models (this has been achieved by disabling a few timeconsuming and notsouseful optimization passes otherwise done by the compiler).

New
compilation_setup
block for specifying a custom compiler or custom compilation flags.


Model, variables and parameters declaration

New syntax to declare model variables and parameters onthefly in the
model
block. To do this, simply follow the symbol name with a vertical line (
, pipe character) and either ane
, anx
, or ap
. For example, to declare a parameter namedalpha
in the model block, you could writealphap
directly in an equation where it appears. Similarly, to declare an endogenous variablec
in the model block you could writece
. (#1386 (closed)) 
New syntax to declare model variable and parameters onthefly in equation tags. In the tag, simply state the type of variable to be declared (
endogenous
,exogenous
, orparameter
followed by an equal sign and the variable name in single quotes. Hence, to declare a variablec
as endogenous in an equation tag, you can type[endogenous='c']
. (see 01d5a130) 
New
epilogue
block for computing output variables of interest that may not be necessarily defined in the model (e.g. various kinds of real/nominal shares or relative prices, or annualized variables out of a quarterly model).


Commandline options

Added the possibility to declare Dynare commandline options in the
.mod
file. 
New option
nopreprocessoroutput
to disable printing of messages from the preprocessor. (#1390 (closed)) 
It is now possible to assign an arbitrary macroexpression to a macrovariable defined on the commandline, using the
D
syntax. (#1696 (closed)) 
New option
linemacro
to revert to the old format of the macroprocessed file (see below).


Preprocessor outputs and inputs

Added JSON output to the preprocessor. A representation of the model file and the whole content of the
.mod
file is saved in.json
files. These JSON files can be easily parsed from any language (C++, Fortran, Python, Julia, MATLAB, Octave…). This new feature opens the possibility to develop alternative backends for the Dynare language. 
⚠ Most files generated by the preprocessor are now grouped under two subdirectories. Assuming your file isFILENAME.mod
, then Mfiles and MEXfiles will be under+FILENAME/
, while other output (JSON, LaTeX, source code for the MEX files) will be underFILENAME/
. 
The macrogenerated output is now more readable (no more line numbers and empty lines). The old behaviour can be restored using the
linemacro
option (see above). 
Ability to call the preprocessor by passing the
.mod
file as a string argument from the macOS or GNU/Linux command line. (#1509 (closed))


dseries classes

New functionalities and efficiency improvements.

Complete rewrite using the new
classdef
syntax and exploiting in place modifications when possible. 
Integration of the
dates
classes withindseries
.


Reporting classes

Automatically create titlepage with page numbers/page titles.

Allow for the removal of headers and footers from a given page.

Allow user to set page number.

Split up report output. Create new files for the preamble, the body of the report, and each individual page of the report.

The classes have been converted to the new
classdef
syntax.


Misc

External functions can be located in MATLAB/Octave namespaces. (#1639 (closed))

Improvements to the balanced growth path test that is performed after Dynare has detrended the model (given the trends on variables declared by the user): the default tolerance has been raised, and a different value can be set with new option
balanced_growth_test_tol
to themodel
block; as a consequence, failing the test is now an error again. (#1389 (closed)) 
New collection of MATLAB/Octave utilities to retrieve and alter objects:
get_irf
,get_mean
,get_shock_stderr_by_name
,get_smooth
,get_update
,set_shock_stderr_value
. (!1686 (merged)) 
⚠ Previously, when some MEX files were missing, Dynare would automatically fall back to slower Mfile functional alternative; this is no longer the case. It is however still possible to manually add these alternatives in the MATLAB/Octave path (they are located undermatlab/missing/mex
; this only applies to themjdgges
,gensylv
,A_times_B_kronecker_C
,sparse_hessian_times_B_kronecker_C
andlocal_state_space_iteration_2
DLLs).
