RE: [R] Forecasting with macroeconomic structural equations models?

Dear Ronaldo,

As you discovered, there are no predict methods in the sem package, either for tsls or sem objects. You might have a look at the systemfit package, which does support predict().

More generally, you should be able to substitute out identities and base predictions on the reduced form of the model. To do so, you'll need forecasts for the exogenous variables in the system.

I hope that this helps,
