Release of Dynare 4.5.7


#1

Dear Dynare users and friends,

We are pleased to announce the release of Dynare 4.5.7.

This is a bugfix release.

The Windows and MacOS packages are already available for download at:

https://www.dynare.org/download/

The GNU/Linux packages (for Debian and Ubuntu LTS) should follow soon.

This release is compatible with MATLAB versions 7.5 (R2007b) to 9.4 (R2018b)
and with GNU Octave version 4.4.1

Here is a list of the problems identified in version 4.5.6 and that have been
fixed in version 4.5.7:

  • The mex-file conducting the QZ decomposition erroneously applied
    the qz_criterium to the square absolute value of eigenvalues
    instead of the absolute value itself (as done in mjdgges.m and the
    AIM solver).

  • In pathological cases, mode_compute=5 (newrat) might enter an
    infinite loop.

  • discretionary_policy might erroneously state that the derivatives
    of the objective function are non-zero if there are NaN present.

  • Dynare++, when conducting the QZ decomposition, erroneously applied
    the qz_criterium to the square absolute value of eigenvalues
    instead of the absolute value itself.

  • Dynare++: IRFs were incorrectly computed.

  • dynare_sensitivity did not display the figures of
    irf_calibration, it only stored them on the disk.

  • Scatter plots generated by dynare_sensitivity did not correctly
    display LaTeX names.

  • Parameter updating via steady state files did not correctly work in
    case of using [static]/[dynamic] equation tags.

  • Memory leaks in k_order_pert (used by higher order stochastic
    simulations) could lead to crashes.

  • Predetermined variables were not properly set when used in model
    local variables.

  • Posterior moment computation did not correctly update the
    covariance matrix of exogenous shocks during posterior sampling.

  • Dynare was crashing with a cryptic message if a non estimated
    parameter was initialized in the estimated_params_init block.

  • The forecast command crashed if the model was declared as linear
    and contained deterministic exogenous variables.

  • Block decomposition is broken when used in conjunction with
    varexo_det.

  • The model was not correctly specified when identification was run
    without another stochastic command in the .mod file
    (e.g. estimation, stoch_simul, etc.).

  • Realtime annualized shock decompositions added the wrong steady state
    value.

  • mh_recover option crashed when using slice sampler.

  • x-axis values in plots of moment restrictions were wrong for
    autocovariances.

On behalf of the Dynare Team,
St├ęphane.
