Introduction to RIMS II

• Non-survey regional input-output (I-O) model
• First developed during the mid 1970s
• Multipliers are available for any county or
  multi-county region in the United States
• Typical users in include consultants, state and
  local governments, federal agencies, universities

3
Typical Applications

• Construction and operation of sports stadiums
• Travel and tourism
• Plant closings
• Firm expansion and relocation
• Changes in the production of individual
  industries resulting from changes in rules or
  regulations

RIMS II Data Requirements

• BEAs national I-O accounts
• Input and output structure of nearly 500 U.S.
  industries
• Benchmark and annual I-O accounts
• BEAs regional economic accounts

6
National I-O Accounts

• Benchmark I-O accounts
• Based on data from detailed economic censuses
  conducted every 5 years by the Bureau of the
  Census
• The 1997 benchmark I-O accounts were released in
  December 2002
• The 2002 benchmark I-O accounts will be published
  in 2007
• The 1997 benchmark I-O accounts are based on the
  North American Industry Classification System
  (NAICS)
• Pre-1997 benchmark I-O accounts are based on the
  Standard Industrial Classification System (SIC)

7
National I-O Accounts Cont.d

• Annual I-O accounts
• For the years between benchmarks, BEA publishes
  annual I-O accounts, which are based on less
  comprehensive data than the benchmark accounts
• The 1999 annual I-O accounts were released in
  December 2002
• The 1999 annual I-O accounts are based on the SIC

8
RIMS II

• Since June 2002, RIMS II has been based on
  national annual I-O accounts
• Currently RIMS II is based on the 1999 national
  annual I-O accounts and 2000 regional accounts
  data
• RIMS II update in progress
• 1997 NAICS-based national benchmark I-O accounts
• 2001 NAICS-based regional accounts data
• RIMS II will be updated after the release of
  national annual I-O accounts for 2002 next spring

9
In the Future

• Accelerating the release of regional estimates
• Continually improving methodologies
• Investigating alternative methods for
  regionalizing
• Expanding the RIMS II output to include
  interregional multipliers
