Models with an endogenous not appearing at time t
by Sébastien Villemot 31 Oct '12

31 Oct '12

I attach a MOD file that is crashing under Dynare 4.3/master. One of its endogenous (m) does not appear at time t (only at t+1). This seems to be a regression from Dynare 4.2, which does not crash and tells that the rank condition is not satisfied. I am going to investigate this, but tell me if you know how to fix it quickly. -- Sébastien Villemot Researcher in Economics http://www.dynare.org/sebastien Phone: +33-1-40-77-84-04

steady state computation in solve1
by Johannes Pfeifer 31 Oct '12

31 Oct '12

Dear Michel, could you have a look at <http://www.dynare.org/phpBB3/viewtopic.php?f=1&t=4151&sid=98769af7c5cb0e2f9 e46ccb899e0210f> http://www.dynare.org/phpBB3/viewtopic.php?f=1&t=4151&sid=98769af7c5cb0e2f9e 46ccb899e0210f The original values for steady state computation are valid. However, later on during steady state computation in solve1 the error message STEADY: numerical initial values incompatible with the following equations 10 is triggered. I think this is a bug. Best, Johannes -- Johannes Pfeifer Haußerstr. 29 72076 Tübingen Tel.: +49-(0)7071-6396184 Mobil.: +49-(0)170-6936820 Germany

[Trac] #240: rewrite getPowerDeriv assignments in temporary terms

#240: rewrite getPowerDeriv assignments in temporary terms --------------------------+------------------------------------------------- Reporter: houtanb | Owner: houtanb Type: bug | Status: new Priority: major | Milestone: 4.3 Component: Preprocessor | Version: Keywords: | --------------------------+------------------------------------------------- From Stephane: In models with power functions of the form x**a (utility functions, production functions, agregation functions, quadratic costs, ...) the evaluation of the jacobian matrix (or higher order derivates) necessitate potentially a huge number of calls to the routine getPowerDeriv (the name of the routine is explicit enough). In my example (a real business cycle model with perfect foresight) most of the time is spent in this routine, while, if my understanding is correct, this is not necessary because x>0. I wrote a mex file (see the new branch called mex-!GetPowerDeriv) as a replacement for the matlab routine, unfortunatly the overhead cost is so high that the use of the mex file increases the total time of execution! In my case I resolved the issue by using option use_dll, but this is not a solution for the majority of our users (they would have to install cygwin/gcc and configure matlab/mex). So my question is: Do we really need to call this routine in all situations ? Would it not be possible to replace calls to this routine by something like: if (abs(x)>1e-12) tmp = ANALYTICAL_EXPRESSION_OF_THE_DERIVATIVE{x,params}; else tmp = 0; end -- Ticket URL: <https://www.dynare.org/trac/ticket/240> Dynare <http://www.dynare.org> The Dynare project

[Trac] #239: Add the possibility of having intermediate files elsewhere than in current directory

#239: Add the possibility of having intermediate files elsewhere than in current directory -------------------------+-------------------------------------------------- Reporter: sebastien | Owner: Type: enhancement | Status: new Priority: major | Milestone: 5.0 Component: General | Version: Keywords: | -------------------------+-------------------------------------------------- Currently Dynare creates all its intermediate files (dynamic, static, ...) in the current directory. It would be useful to have the possibility of choosing the directory where intermediate files are created.
