This page documents known bugs in Dynare. A bug is associated with the latest version in which it appears (i.e. it has been or will be fixed in the next version).

Version 4.0.4

• decision rules for stochastic models with leads greater than 2 are wrong

• in deterministic models, putting a shocks block before an endval block leads to wrong results; the right order is to put endval before shocks

• this version doesn't support MATLAB R2009a and R2009b on 64-bit platforms

• in estimation, option mode_file shouldn't be used if the posterior mode has been computed for a model with a different specification, even if the list of estimated parameters is the same. This can result in wrong results without error message

• with Octave, in stochastic simulations, Dynare will return wrong eigenvalues if the MEX file "mjdgges" is not present
• the resid() function messes up things when doing deterministic simulations, and should be avoided in that case

Version 4.0.2

• Option dr_algo has been suppressed without warning in this version

Version 4.0.1

• shocks_file option is missing

• there is a bug in DsgeSmoother.m for models with measurement errors (thanks for hlousek for reporting it)

• Octave crashes in mode_check.m, MakeAllFigures.m and PosteriorIRF.m, because of missing saveas() function (thanks to Gianni Lombardo for reporting)

• estimation crashes when mode_file is specified, at least under Octave (thanks to Gianni Lombardo for reporting)

Version 4.0.0

• typo at the top of DiffuseKalmanSmootherH1.m (thanks to Tsu-ting Tim Lin for reporting)

• call to cumulative normal distribution is broken (thanks to Karl Walentin for reporting)
• script for building MEX files under Matlab R2008a is broken (thanks to Slim Bridji for reporting)
• homotopy mode 3 is broken
• BVAR à la Sims: Dynare doesn't accept integer values for tau and lambda parameters (thanks to Aqua for reporting)
