The problem of fault detection, isolation and identification are for the case of faulty output growth models describing biregional and multisectoral economies. The model is in discrete time descriptor form including non measurable total outputs and uncertain final demands. For this model the problems of fault detection, isolation and identification are solved on the basis of the design of a bank of unknown input discrete time observers provide a residual index. The present results are successfully applied to a biregional 12 sector economy where 4 different fault scenarios including single and multi faults are considered.
