Release of Dynare 4.5.3
by Stéphane Adjemian 19 Oct '17

19 Oct '17

Dear Dynare users and friends, We are pleased to announce the release of Dynare 4.5.3. This is a bugfix release. It comes less than 24 hours after the previous release, because version 4.5.2 was affected by a critical bug for MATLAB older than R2016b. The Windows packages are already available for download at: http://www.dynare.org/download/dynare-stable The Mac and GNU/Linux packages (for Debian and Ubuntu LTS) should follow soon. This release is compatible with MATLAB versions 7.3 (R2006b) to 9.3 (R2017b) and with GNU Octave versions 4.2. Here is a list of the problems identified in version 4.5.2 and that have been fixed in version 4.5.3: - `isfile` routine was failing with MATLAB older than R2016b. This bug did not affect Octave. On behalf of the Dynare Team, Stéphane.

Release of Dynare 4.5.2

Dear Dynare users and friends, We are pleased to announce the release of Dynare 4.5.2. This is a bug fix release. The Windows packages are already available for download at: http://www.dynare.org/download/dynare-stable The Mac and GNU/Linux packages (for Debian and Ubuntu LTS) should follow soon. This release is compatible with MATLAB versions 7.3 (R2006b) to 9.3 (R2017b) and with GNU Octave versions 4.2. Here is a list of the problems identified in version 4.5.1 and that have been fixed in version 4.5.2: - Fixed bug in perfect foresight solver: + If expected shocks were declared after the terminal period, as specified by the `periods` option, Dynare was crashing. + Models declared with the `linear` option were crashing if exogenous variables were present with a lead or lag. - After ML or Bayesian estimation when the smoother option or `mh_replic=0` were not specified, not all smoothed measurement errors were displayed. - Fixed error in reference manual about the `conditional_forecasts` command. - Fixed smoother behaviour, provide informative error instead of crashing when model cannot be solved. - The `nopathchange` preprocessor option was always triggered, regardless of whether it was passed or not. - When `ramsey_policy` is used, allow state variables to be set in `histval` block. - `histval` erroneously accepted leads, leading to cryptic crashes. - The prior MC draws from previous runs were not deleted, potentially resulting in loading stale files. - `estim_params_` was being declared `global` more than once. - Fixed crashes happening when simulating linear models with order>1. - Make empirical moments independent of `simul_replic`, as stated in the reference manual, by outputting moments computed with the first simulated sample. - The `prior_function` required a preceding `estimation`-command to properly set up the prior. - If the mode for a parameter was at exactly 0, `mode_check` was crashing. - Fixed `get_posterior_parameters`-routine which should not do more than getting parameters. As a consequence, the `shock_decomposition`-command did not correctly set the `parameter_set` for use in subsequent function calls if shocks are correlated or measurement error is present. - Fixed bug in Ramsey problem with constraints both on a policy instrument and another variable. Note that the constraint on a variable that is not an instrument of the Ramsey problem must be written with an equation tag in the model block. - Fixed bug in Ramsey problem with constraints on policy instrument. - Fixed crash with optimizer 5 when not used with DSGE model at order 1. - Fixed mex file used for third order approximation (was crashing on Matlab/Windows 7).
