Release of Dynare 4.5.4
by Stéphane Adjemian 03 Feb '18

03 Feb '18

Dear Dynare users and friends, We are pleased to announce the release of Dynare 4.5.4. This is a bugfix 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 7.5 (R2007b) to 9.3 (R2017b) and with GNU Octave versions 4.2. Here is a list of the problems identified in version 4.5.3 and that have been fixed in version 4.5.4: - The `type` option of `plot_shock_decomposition` was always set to `qoq` regardless of what is specified. - Bug in GSA when no parameter was detected below pvalue threshold. - Various bug fixes in shock decompositions. - Bug in reading in macro arrays passed on `dynare` command line via the `-D` option. - Estimation with missing values was crashing if the `prefilter` option was used. - Added a workaround for a difference in behaviour between Octave and Matlab regarding the creation of function handles for functions that do not exist in the path. With Octave 4.2.1, steady state files did not work if no auxiliary variables were created. - The `stoch_simul` command was crashing with a cryptic message if option `order=3` was used without setting `k_order_solver`. - In cases where the prior bounds are infinite and the mode is estimated at exactly 0, no `mode_check` graphs were displayed. - Parallel execution of MCMC was broken in models without auxiliary variables. - Reading data with column names from Excel might crash. - The multivariate Kalman smoother was crashing in case of missing data in the observations and `Finf` became singular. - The `plot_shock_decomposition` command ignored various user-defined options like `fig_name`, `use_shock_groups` or `interactive` and instead used the default options. - Nested `@#ifdef` and `@#ifndef` statements don't work in the macroprocessor. On behalf of the Dynare Team, Stéphane.

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.

Release of Dynare 4.5.2
by Stéphane Adjemian 19 Oct '17

19 Oct '17

Dear Dynare users and friends, We are pleased to announce the release of Dynare 4.5.2. 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).

(1987), + `mode_compute=101` Uses SOLVEOPT as described by Kuntsevich and Kappel (1997), + `mode_compute=102` Uses `simulannealbnd` from Matlab's Global Optimization Toolbox (if available), + New option `silent_optimizer` to shut off output from mode computing/optimization, + New options `verbosity` and `SaveFiles` to control output and saving of files during mode computing/optimization. - LaTeX output + New command `write_latex_original_model`, + New option `write_equation_tags` to `write_latex_dynamic_model` that allows printing the specified equation tags to the generate LaTeX code, + New command `write_latex_parameter_table` that writes the names and values of model parameters to a LaTeX table, + New command `write_latex_prior_table` that writes the descriptive statistics about the prior distribution to a LaTeX table, + New command `collect_latex_files` that creates one compilable LaTeX file containing all TeX-output. - Misc. + Provides 64bit preprocessor, + Introduces new path management to avoid conflicts with other toolboxes, + Full compatibility with Matlab 2014b's new graphic interface, + When using `model(linear)`, Dynare automatically checks whether the model is truly linear, + `usedll`, the `msvc` option now supports `normcdf`, `acosh`, `asinh`, and `atanh`, + New parallel option `NumberOfThreadsPerJob` for Windows nodes that sets the number of threads assigned to each remote MATLAB/Octave run, + Improved numerical performance of `schur_statespace_transformation` for very large models, + The `all_values_required` option now also works with `histval`, + Add missing `horizon` option to `ms_forecast`, + BVAR now saves the marginal data density in `oo_.bvar.log_marginal_data_density` and stores prior and posterior information in `oo_.bvar.prior` and `oo_.bvar.posterior`. * Bugs and problems identified in version 4.4.3 and that have been fixed in version 4.5.0: - BVAR models + `bvar_irf` could display IRFs in an unreadable way when they moved from negative to positive values, + In contrast to what is stated in the documentation, the confidence interval size `conf_sig` was 0.6 by default instead of 0.9. - Conditional forecasts + The `conditional_forecast` command produced wrong results in calibrated models when used at initial values outside of the steady state (given with `initval`), + The `plot_conditional_forecast` option could produce unreadable figures if the areas overlap, + The `conditional_forecast` command after MLE crashed, + In contrast to what is stated in the manual, the confidence interval size `conf_sig` was 0.6 by default instead of 0.8. + Conditional forecasts were wrong when the declaration of endogenous variables was not preceeding the declaration of the exogenous variables and parameters. - Discretionary policy + Dynare allowed running models where the number of instruments did not match the number of omitted equations, + Dynare could crash in some cases when trying to display the solution, + Parameter dependence embedded via a `steady_state` was not taken into account, typically resulting in crashes. - dseries class + When subtracting a dseries object from a number, the number was instead subtracted from the dseries object. - DSGE-VAR models + Dynare crashed when estimation encountered non-finite values in the Jacobian at the steady state, + The presence of a constant was not considered for degrees of freedom computation of the Gamma function used during the posterior computation; due to only affecting the constant term, results should be be unaffected, except for model_comparison when comparing models with and without. - Estimation command + In contrast to what was stated in the manual, the confidence interval size `conf_sig` for `forecast` without MCMC was 0.6 by default instead of 0.9, + Calling estimation after identification could lead to crashes, + When using recursive estimation/forecasting and setting some elements of `nobs` to be larger than the number of observations T in the data, `oo_recursive_` contained additional cell entries that simply repeated the results obtained for `oo_recursive_T`, + Computation of Bayesian smoother could crash for larger models when requesting `forecast` or `filtered_variables`, + Geweke convergence diagnostics were not computed on the full MCMC chain when the `load_mh_file` option was used, + The Geweke convergence diagnostics always used the default `taper_steps` and `geweke_interval`, + Bayesian IRFs (`bayesian_irfs` option) could be displayed in an unreadable way when they move from negative to positive values, + If `bayesian_irfs` was requested when `mh_replic` was too low to compute HPDIs, plotting was crashing, + The x-axis value in `oo_.prior_density` for the standard deviation and correlation of measurement errors was written into a field `mearsurement_errors_*` instead of `measurement_errors_*`, + Using a user-defined `mode_compute` crashed estimation, + Option `mode_compute=10` did not work with infinite prior bounds, + The posterior variances and covariances computed by `moments_varendo` were wrong for very large models due to a matrix erroneously being filled up with zeros, + Using the `forecast` option with `loglinear` erroneously added the unlogged steady state, + When using the `loglinear` option the check for the presence of a constant was erroneously based on the unlogged steady state, + Estimation of `observation_trends` was broken as the trends specified as a function of deep parameters were not correctly updated during estimation, + When using `analytic_derivation`, the parameter values were not set before testing whether the steady state file changes parameter values, leading to subsequent crashes, + If the steady state of an initial parameterization did not solve, the observation equation could erroneously feature no constant when the `use_calibration` option was used, + When computing posterior moments, Dynare falsely displayed that moment computations are skipped, although the computation was performed correctly, + If `conditional_variance_decomposition` was requested, although all variables contain unit roots, Dynare crashed instead of providing an error message, + Computation of the posterior parameter distribution was erroneously based on more draws than specified (there was one additional draw for every Markov chain), + The estimation option `lyapunov=fixed_point` was broken, + Computation of `filtered_vars` with only one requested step crashed Dynare, + Option `kalman_algo=3` was broken with non-diagonal measurement error, + When using the diffuse Kalman filter with missing observations, an additive factor log(2*pi) was missing in the last iteration step, + Passing of the `MaxFunEvals` and `InitialSimplexSize` options to `mode_compute=8` was broken, + Bayesian forecasts contained initial conditions and had the wrong length in both plots and stored variables, + Filtered variables obtained with `mh_replic=0`, ML, or `calibrated_smoother` were padded with zeros at the beginning and end and had the wrong length in stored variables, + Computation of smoothed measurement errors in Bayesian estimation was broken, + The `selected_variables_only` option (`mh_replic=0`, ML, or `calibrated_smoother`) returned wrong results for smoothed, updated, and filtered variables, + Combining the `selected_variables_only` option with forecasts obtained using `mh_replic=0`, ML, or `calibrated_smoother` leaded to crashes, + `oo_.UpdatedVariables` was only filled when the `filtered_vars` option was specified, + When using Bayesian estimation with `filtered_vars`, but without `smoother`, then `oo_.FilteredVariables` erroneously also contained filtered variables at the posterior mean as with `mh_replic=0`, + Running an MCMC a second time in the same folder with a different number of iterations could result in crashes due to the loading of stale files, + Results displayed after Bayesian estimation when not specifying the `smoother` option were based on the parameters at the mode from mode finding instead of the mean parameters from the posterior draws. This affected the smoother results displayed, but also calls to subsequent command relying on the parameters stored in `M_.params` like `stoch_simul`, + The content of `oo_.posterior_std` after Bayesian estimation was based on the standard deviation at the posterior mode, not the one from the MCMC, this was not consistent with the reference manual, + When the initialization of an MCMC run failed, the metropolis.log file was locked, requiring a restart of Matlab to restart estimation, + If the posterior mode was right at the corner of the prior bounds, the initialization of the MCMC erroneously crashed, + If the number of dropped draws via `mh_drop` coincided with the number of draws in a `_mh'-file`, `oo_.posterior.metropolis.mean` and `oo_.posterior.metropolis.Variance` were NaN. -

Global Sensitivity Analysis + Sensitivity with ML estimation could result in crashes, + Option `mc` must be forced if `neighborhood_width` is used, + Fixed dimension of `stock_logpo` and `stock_ys`, + Incomplete variable initialization could lead to crashes with `prior_range=1`. - Indentification + Identification did not correctly pass the `lik_init` option, requiring the manual setting of `options_.diffuse_filter=1` in case of unit roots, + Testing identification of standard deviations as the only parameters to be estimated with ML leaded to crashes, + Automatic increase of the lag number for autocovariances when the number of parameters is bigger than the number of non-zero moments was broken, + When using ML, the asymptotic Hessian was not computed, + Checking for singular values when the eigenvectors contained only one column did not work correctly, - Model comparison + Selection of the `modifiedharmonicmean` estimator was broken, - Optimal Simple Rules + When covariances were specified, variables that only entered with their variance and no covariance term obtained a wrong weight, resulting in wrong results, + Results reported for stochastic simulations after `osr` were based on the last parameter vector encountered during optimization, which does not necessarily coincide with the optimal parameter vector, + Using only one (co)variance in the objective function resulted in crashes, + For models with non-stationary variables the objective function was computed wrongly. - Ramsey policy + If a Lagrange multiplier appeared in the model with a lead or a lag of more than one period, the steady state could be wrong. + When using an external steady state file, incorrect steady states could be accepted, + When using an external steady state file with more than one instrument, Dynare crashed, + When using an external steady state file and running `stoch_simul` after `ramsey_planner`, an incorrect steady state was used, + When the number of instruments was not equal to the number of omitted equations, Dynare crashed with a cryptic message, + The `planner_objective` accepted `varexo`, but ignored them for computations, - Shock decomposition + Did not work with the `parameter_set=calibration` option if an `estimated_params` block is present, + Crashed after MLE. - Perfect foresight models + The perfect foresight solver could accept a complex solution instead of continuing to look for a real-valued one, + The `initval_file` command only accepted column and not row vectors, + The `initval_file` command did not work with Excel files, + Deterministic simulations with one boundary condition crashed in `solve_one_boundary` due to a missing underscore when passing `options_.simul.maxit`, + Deterministic simulation with exogenous variables lagged by more than one period crashed, + Termination criterion `maxit` was hard-coded for `solve_algo=0` and could no be changed, + When using `block`/`bytecode`, relational operators could not be enforced, + When using `block` some exceptions were not properly handled, leading to code crashes, + Using `periods=1` crashed the solver (bug only partially fixed). - Smoothing + The univariate Kalman smoother returned wrong results when used with correlated measurement error, + The diffuse smoother sometimes returned linear combinations of the smoothed stochastic trend estimates instead of the original trend estimates. - Perturbation reduced form + In contrast to what is stated in the manual, the results of the unconditional variance decomposition were only stored in `oo_.gamma_y(nar+2)`, not in `oo_.variance_decomposition`, + Dynare could crash when the steady state could not be computed when using the `loglinear` option, + Using `bytcode` when declared exogenous variables were not used in the model leaded to crashes in stochastic simulations, + Displaying decision rules involving lags of auxiliary variables of type 0 (leads>1) crashed. + The `relative_irf` option resulted in wrong output at `order>1` as it implicitly relies on linearity. - Displaying of the MH-history with the `internals` command crashed if parameter names did not have same length. - Dynare crashed when the user-defined steady state file returned an error code, but not an conformable-sized steady state vector. - Due to a bug in `mjdgges.mex` unstable parameter draws with eigenvalues up to 1+1e-6 could be accepted as stable for the purpose of the Blanchard-Kahn conditions, even if `qz_criterium<1`. - The `use_dll` option on Octave for Windows required to pass a compiler flag at the command line, despite the manual stating this was not necessary. - Dynare crashed for models with `block` option if the Blanchard-Kahn conditions were not satisfied instead of generating an error message. - The `verbose` option did not work with `model(block)`. - When falsely specifying the `model(linear)` for nonlinear models, incorrect steady states were accepted instead of aborting. - The `STEADY_STATE` operator called on model local variables (so-called pound variables) did not work as expected. - The substring operator in macro-processor was broken. The characters of the substring could be mixed with random characters from the memory space. - Block decomposition could sometimes cause the preprocessor to crash. - A bug when external functions were used in model local variables that were contained in equations that required auxiliary variable/equations led to crashes of Matlab. - Sampling from the prior distribution for an inverse gamma II distribution when `prior_trunc>0` could result in incorrect sampling. - Sampling from the prior distribution for a uniform distribution when `prior_trunc>0` was ignoring the prior truncation. - Conditional forecasts were wrong when the declaration of endogenous variables was not preceeding the declaration of the exogenous variables and parameters.

Dynare Summer School 2016
by Stéphane Adjemian 21 Mar '16

21 Mar '16

Dear Dynare friends, The Dynare Summer School 2016 will take place from June 6 to June 10, 2016 in Le Mans, France. # Goals of the Summer School The school will provide an introduction to Dynare and to Dynamic Stochastic General Equilibrium (DSGE) modelling. The courses will focus on simulation and estimation of DSGE models with Dynare. It will be also the occasion to introduce the new features in Dynare. Participants will be given the opportunity to present a research paper/work. At the end of each day a one hour slot will be reserved for that purpose. This Summer school is aimed at beginners as well as at more experienced researchers. PhD students are encouraged to participate. # Application Interested people should apply by sending an email to summerschool(a)dynare.org. Application should be done *no later than April 22, 2016*. You will have to attach a CV and a recent research paper. Those willing to present a research paper/work should manifest their intention in the email. We will confirm acceptance by April 25, 2016. People working in organizations member of DSGE-net (Bank of Finland, Banque de France, Capital Group, European Central Bank, Federal Reserve Bank of Atlanta, Norges Bank, Sverige Riksbank, Swiss National Bank) should register via their network representative. # Registration Fee Registration fee (including breakfasts, lunches, coffe breaks, one diner, *and* accomodation): 450 €. Note that this year we had to prebook the hotel rooms because none will be available when we will confirm acceptance to the Summer school (the city hosts the 24 heures du Mans in June). # Workshop Animators - Stéphane Adjemian (Université du Maine) - Michel Juillard (Banque de France) - Frédéric Karamé (Université du Maine) - Johannes Pfeifer (University of Mannheim) This workshop is organized with the support of Université du Maine, CEPREMAP and DSGE-net. # Preliminary Program The preliminary program will be available soon on Dynare's website. # Workshop Venue Université du Maine Avenue Olivier Messiaen 72000 Le Mans France # Workshop Organization This is a “laptop only” workshop. Each participant is required to come with his/her laptop computer with MATLAB version 7.5 (R2007b) or above installed. We will provide WiFi access, but participants shouldn't rely on it to access a MATLAB license server at their own institution. As an alternative to MATLAB, it is possible to use GNU Octave (free software, compatible with MATLAB syntax; see http://www.dynare.org/download/octave for details on GNU Octave installation). On behalf of the Dynare Team, Stéphane. -- Stéphane Adjemian Université du Maine, Gains & Cepremap
