Results of a Delphi survey in drawing up the input–output tables for Catalonia

This work presents the results of an ambitious and innovative use of the Delphi technique in supplying a quantitative economic model, specifically in the preparation of the Input–Output Tables for Catalonia (TIOC 2001). Using this technique for obtaining subjective information from experts comes forward as a valid and reliable option for improving the quality of the data with which the Input–Output tables are constructed, also providing further economic and social advantages. The application presented thus opens up an interesting field of development for this technique and also gives several contributions for appraising the execution of a Delphi exercise of this type.
