Extended Path disagreeing with OccBin and DynareOBC on linear models
DynareOBC contains tests which solve the same otherwise linear model with the Extended Path, OccBin, and with DynareOBC. OccBin and DynareOBC agree (up to the order of 10^(-8)), but the extended path is way off (e.g. responses 10 times larger).
(It's just possible that there's something up with my version of Dynare, but the fact that running git diff upstream/master -- matlab/ep/
produces no output suggests that this probably isn't the problem at least.)
The tests are in this folder: https://github.com/tholden/dynareOBC/tree/master/Tests/ComparisonOfPerfectForesightSolutionsForLinearModels
You could just compare OccBin vs ExtendedPath by commenting out the appropriate lines of RunAllAndCompare.m, saving you the trouble of setting up DynareOBC.
