As a demonstration of the ability of Betahat to estimate and simulate multiequation systems we are providing the command and datasets for well known econometric models.  As time permits we plan to post command files and datasets for more models on this page.

FairModel

We obtained the FairModel from the FairModel site, which has complete documentation for the model.  If you have a full version of Betahat (not the demo since it has a restriction on the number of observations) you can re-estimate and simulate this model. The FairModel in Betahat has 30 stochastic equations and 179 identities.  We provide the raw data, and the command file for Betahat to read in the data, perform transformations, specify, estimate and save the equations, specify and save the identities, and simulate the model.  If you would like to view the output of Betahat for this model when run in Betahat we provide that also.  Versions 3.09 and later of Betahat have several features that make the simulations for this model solve easier.  These are mentioned in the command file.

Mark III Model from the International Monetary Fund 

We obtained the Mark III model from the IMF site, which has complete documentation for the model.  The International Monetary Fund is the original source of this material.  

If you have a full version of Betahat (not the demo since it has a restriction on the number of observations) you can simulate the Mark III model in Betahat.  We provide the Steady State model, the Rational Expectations model, and a demonstration simulating this model in Betahat.  File Mark3rn2_Betahat.prg provides the commands, and Mark3rn2_Betahat.RTF contains the results for a simulation similar to those at the IMF web site.  The sim will provide a shock to the Canadian money supply starting in 2001.  The results are provided in standard Betahat format, which is Rich Text Format.  Other formats for output are available in Betahat, such as Excel.

Note, version 5.00 and later of Betahat is required to solve this model.

FRB/US model from the US Federal Reserve

The version of the FRB/US model the fed sent us does not have any future values for the exogenous variables.  To get the model running, we set all future values of the exogenous variables equal to their values at the last history year of data.  The FRB/US model in Betahat contains the raw files from the fed, detailed instructions for moving the model into Betahat, and the completed model in Betahat format.  File FRB_US_DOC.zip contains the documentation for the model.

Note, version 5.00 and later of Betahat is required to solve this model.
