Disaggregating Input--Output Tables by the Multidimensional RAS Method: A Case Study of the Czech Republic

Understand

The RAS method is an iterative procedure that bi-proportionally scales an input-output table to be consistent with given row and column sums.

• It can be used to disaggregate an annual national table to more detailed tables, such as regional, quarterly, and domestic/imported tables.
• However, the regular two-dimensional RAS method does not ensure the consistency of the disaggregated tables with the original table.
• For this problem, we use the multidimensional RAS method, which besides input and output totals, also ensures regional, quarterly, and domestic/imported totals.
