I take it your friend is interested in large scale macro econometric models involving perhaps more than a thousand equations. The software one would like to use might involve managing the model database, estimating the model and simulating the model. If the model involves rational expectations these simulations will be very demanding. R would probably handle a lot of the estimation requirements and probably most of the data management. I do not know of anyone that has handled the more elaborate RE simulations in R. It would involve considerable programming. The only free software that does this kind of work is the Fair-Parke program available from http://fairmodel.econ.yale.edu/.
If the model has been set up by another person you might be advised to use the software that the maintainers of the model use. TROLL is widely used in Central Banks and organisations such as the IMF ECB etc. It would be a fairly big job to translate a large scale macro model from a system such as TROLL or MODELEASY or similar to another language. If the model is relatively small then any statistical system that can store data, estimate structural equations and simulate them is ideal. R would be suitable in this case. If RE are involved you may need special software or some programming.
