From Regional IO Tables to Interregional SU Models

What is it about?

An overview of non-survey construction methods for regional input-output tables (RIOTs) reveals a systematic over-estimation of regional multipliers. The Cell-corrected RAS method uses the nowadays abundance of easily available survey-based RIOTs to improve the cell estimates of unknown RIOTs. Moreover, semi-survey bi-regional IOTs may be constructed with a double-entry construction method that requires minimal additional survey data about the spatial destination of total sales by regional industry. Rectangular supply-use tables (SUTs) have become prevalent over square IOTs. The possible set-ups of interregional SUTs are explained along with the models that may be based on them. Finally, large differences are shown to exist between the top-down interregional and the bottom-up international construction of SUTs.
