This paper presents an empirical exercise in economic lorecast using traditional time series methods, such as ARlMA, and unobservable components models (VCM), and artificial neural networks (ANN). We use monthly gross industrial output data for the state ofRio Grande do Sul (Drazil) to per-lorm a comparative exercise and access the relative perlormance ofthe dirrerent forecasting methods. The results show that ANN lorecast more accurately than ARIMA models, but the comparison with VCM is not quite straightli.mvard. The VCM is found to produce beuer one step ahead forecast than the ANN, but the perlormance ofthe ANN lor larger lorecasts horizons shows that, specially once a proper modeling methodology has been established, it may be a valuab...
