Version 3

Changes in Dynare version 3

Version 3.06

3.066

Bug fixed:

bug with conditional compilation instructions in MODEL block
bug with variance computation

3.064

Bug fixed:

bug with penalty in Metropolis iterations
new version of Chris Sims optimizer (thanks Chris!)
bug in osr
bug in estimating correlation coefficients
typos in metropolis.m
function call with empty arguments that caused problems with Matlab version < 7

3.062

New features:

optimal simple policy rules and optimal policy under commitment for linear models
forecasting for calibrated models
anticipated exogenous deterministic shocks in the simulation of stochastic models
conditional compilation of part of the *.mod file

The manual has been updated (the pdf version is deficient, use the HTML one)

Bug fixed:

bug in Metropolis iterations with one chain
removed restriction on name of observed variables
Dynare uses now 500 draws among Metropolis iterations when computing posterior distribution of forecast, IRF, moments or smoothed variables
Corrected a bug in Diffuse Kalman filter and smoother

Version 3.05

3.051

correcting bug in computation of 2nd order approximation for models with leads on more than one period. Please redo your computations. Sorry about that.
correcting bug in estimation of models with lags on more than one period
correcting bug in forecasting after estimation
correcting bug in relative_irf in estimation
binaries for Linux x86 are released

Version 3.04

3.046

correcting bug in fs2000a example
correcting several bugs in posterior distribution of various statistics
correcting inefficiency in simulation of second order approximated models
correcting the bug with a parameter called 'c' in deterministic models

3.042

correcting bug with option optim in estimation

3.041

correcting bug with option bayesian_irf in estimation

3.04

correcting bug for 2nd order approximation with leads on more than one period
correcting bug for backward-looking models with lags on more than one period
correcting bug for forecast of trending variables in estimation
correcting bug in computation of modified harmonic mean estimator of marginal density in estimation
correcting bugs and modified diffuse filter and smoother (thanks to Marco Ratto for suggestions)
adding a noprint option in stoch_simul for better loops
an expression can be used to set option simul_seed
from now on, models which don't have a unique stable solution (Blanchard and Kahn condition) are never computed by stoch_simul

The manual still needs to be updated

Version 3.03

correcting bug on computation of (correction) in 2nd order approximation present in version 3.02 and 3.021
correcting bug on check with backward models
newer version of the optimizer contributed by Marco Ratto (mode_compute=5)

Version 3.02

3.021

correcting bug with deterministic shocks
correcting bug with check for backward models
correcting bug in creation of TeX tables in dynare_estimation (yet undocumented feature)

3.02

allows for leads on more than one period for 2nd order approximation
estimation of correlation coefficients of shocks or measurement errors are again possible (the manual still needs to be updated)
correction of bugs reported by M. Ratto, E. Pytlarczyk and JG Sahuc in the Diffuse Filter (thank you)

Version 3.01

3.011

Bug corrections to the Diffuse Smoother.

3.01

We use now the true diffuse prior Kalman filter proposed by Durbin and Kalman for nonstationary models.

Version 3.0

Version 3.0 is the first stable version with estimation support. It corresponds to the test version that was available through 2004. Note that the possibility of estimating correlation coefficients between shocks isn't available. There was a problem with the testing version to insure that the variance matrix of the shocks is indeed positive definite. Users should explicitly model that a given equation is affected by two uncorrelated shocks.
