Editing Input–output model (section)

=== Regional multipliers ===
While national input–output tables are commonly created by countries' statistics agencies, officially published regional input–output tables are rare. Therefore, economists often use [[Economic base analysis|location quotients]] to create regional multipliers starting from national data.<ref>{{cite journal | url=https://www.tandfonline.com/doi/abs/10.1080/00343409512331349173?journalCode=cres20 | doi=10.1080/00343409512331349173 | title=On the Appropriate Use of Location Quotients in Generating Regional Input–Output Tables | date=1995 | last1=Flegg | first1=A.
