Regionalization
Regionalization Adjustments
• Local and non-local purchases• Commuting patterns• State wage rates• Taxes and savings

Local Purchases
Regionalizing I-O Tables
• Assume locally-produced output is preferred
• Regionalizing indexes are applied to I-O dataHigher index = more self sufficient
• Regionalization provides an I-O table weighted to reflect local self-sufficiency

Leakages Reduce Potential Impacts
Commuting Patterns
Commuting Patterns Adjust for Residency
• Commuters living outside the region reduce local earnings and employment impacts
• Type II multipliers only include the induced impact of residence-adjusted worker spending
• Ideally, the region selected for an impact will match the regional commuter shed

Wage and Tax Rates
Local Labor Markets
• State-level wage and tax rates
• National-level savings rates
• Assume labor (and other resources) are freely available at current wages (and prices)

Know Your Model
Data Gaps
• Universal, periodic, consistent regional data are difficult and costly to collect
•Model users need to know how their model fills gaps in regional data
• Ask whether model results look reasonable
