using RIMS II - Provide examples of applications
4RIMS II Has Been Used to Analyze aVariety of
Projects
- Opening and closing military bases
- Tourist expenditures
- New energy facilities
- Construction of sports facilities
- New retail establishments
- New airports or port facilities
- Opening and closing manufacturing plants
- University expenditures
5How Have RIMS II Multipliers Been Used?
6Who Uses RIMS II Multipliers?
7Questions You May Be Asked
- How will the new project or program affect a
local economy? - What is the impact of increasing or decreasing
production? - How many new jobs will be created or lost?
- How will wage and tax revenues be affected?
8Questions Youll Need to Ask
- Which industries will be affected initially?
- What is the value of the initial increase or
decrease in production? - How many jobs will be initially affected?
- How much earnings will be received by the
employees who are initially affected? - Geographically, what area will be affected?
- How long will the initial phase last?
- Will there be more than one phase?
9RIMS II
- Demand-based, like all regional I-O models
- Used for analyzing the impacts of changes in
demand rather than changes in supply - Assumes Amount of inputs that an industry uses
depends on the level of output that it produces - An increase or decrease in output will result in
a proportional increase or decrease in inputs - Multipliers can be used to estimate the impacts
of final-demand changes assuming the final-demand
changes do not alter the structure of the economy
10Final-Demand Change
- Change in the level of output produced for final
demand, for example - Hotel services purchased by tourists
- Measured by hotel receipts
- Investment in new construction
- Measured by construction costs
- Investment in computers
- Measured by the cost of computers in producers
values transportation costs wholesale and
retail trade margins - Exports of manufactured goods and services
- Measured by the cost of the goods in producers
values transportation costs wholesale and
retail trade margins - For services, transportation costs and wholesale
and retail trade margins do not apply
11What Youll Need to be Concerned About
- RIMS II cant be used to estimate the effects of
changes to the structure of the economy - Productivity changes
- Price changes
- Wage changes
- Tax changes
- Brand new industry or an industry leaving the
region

14Ordering RIMS II Multipliers
15Selecting Data Series and Multiplier Types
16Type I and Type II Multipliers
- Type I multipliers (exogenous)
- Measure economic impact of industries only
- Excludes impacts of household expenditures
- Total requirements direct indirect
- Type II multipliers (households endogenous)
- Measure economic impact of industries and
household expenditures - Total requirements direct indirect induced
- More commonly used than Type I multipliers
17Annual vs. Benchmark Series
- Annual series
- More current, less detailed
- 2005 national annual I-O data and 2005 regional
data - Benchmark series
- More detailed, less current
- 1997 national benchmark I-O data and 2005
regional data
18Selecting Your Region
19Determining Your Region A Balancing Act
- General rule Use multipliers for the region
that supplies a large proportion of the direct
inputs - Using multipliers for a region that is too
broadly defined may overstate the impacts - A larger region usually results in larger
multipliers because of fewer leakages - A common mistake is to use statewide multipliers
to estimate local level impacts - Using multipliers for a region that is too
narrowly defined may understate the impacts
20Selecting Your Industry
21Accessing Your Multipliers
- Three ways to access your multipliers
- Viewing and printing PDF versions of the summary
multiplier tables - Using the Multiplier Quick View
- Using the RIMS II Viewer Software
22RIMS II Multipliers
23Important Concepts
- Final Demand
- Purchases of goods and services by final users
- Output
- Intermediate purchases plus value added
- Value added
- Sum of earnings (includes proprietors), taxes on
production and imports less subsidies, and
non-proprietors portion of gross operating
surplus - Earnings
- Sum of wages and salaries, proprietors income,
and employer contributions for health insurance
excluding contributions for social insurance - Employment
- Number of jobs
- Full- and part-time (includes proprietors)
24Approaches to Using RIMS II Multipliers
- Use data on final-demand changes
- Final-demand changes multiplied by final-demand
multipliers - Use data on initial changes in labor earnings and
employment - Initial changes multiplied by direct-effect
multipliers - Use data on changes in the bill-of-goods
- Regional purchases multiplied by final-demand
multipliers
25Application Example Increase in Cookie Sales
- Question What is the total impact on a region
of a 10 million increase in cookie sales? - Example will use
- Multipliers for I-O industry code 311821 for the
Columbus GA-AL MSA - 10 million increase in cookie sales in
producers values - 1.4 million increase in earnings earned by
cookie manufacturing employees residing in the
Columbus GA-AL MSA - 32 new cookie manufacturing jobs held by
employees residing in the Columbus GA-AL MSA - Example assumes
- Cookies are manufactured in the region and sold
outside the region.

40Comparison of Impacts Endogenous vs. Exogenous
Multipliers
41Key Points!
- Choose appropriately sized region
- Use the most detailed industry multipliers
- Impacts estimated using final-demand multipliers
will be similar to those made using direct-effect
multipliers as long as the underlying RIMS II
assumptions are consistent with the users data
42More Key Points!
- Do NOT add
- Final-demand change to the output impact
- Output impacts to earnings impacts
- Final-demand employment multiplier
- Measured on the basis of a 1 million
final-demand change - Total number of full-time and part-time jobs
- Use the number of jobs held by employees residing
in the region with direct-effect employment
multipliers - Use earnings received by employees residing in
the region with direct-effect earnings multipliers
43Hands-on Exercise 1
- In this exercise you will
- Use two approaches to estimate impacts of an
investment in new construction - Approach 1 A final-demand change is multiplied
by final-demand multipliers to estimate the
impacts - Approach 2 Initial changes in earnings and
employment are multiplied by direct-effect
multipliers to estimate the impacts - Compare the impacts obtained from using both
approaches
44Hands-on Exercise 1 Assumptions
- Assumptions and information for this exercise
- Final-demand for new construction (I-O industry
code 230000) is 100 million - Initial change in earnings of employees residing
in the region is 34 million - Initial change in regional employment is 975 jobs
- NOTE Worksheets contain the appropriate
multipliers for this exercise.
45Household Multipliers
- Households do not produce goods and services
- In a household endogenous model, household
purchases are NOT final demand - Total output multiplier table
- Household row entries are the sum of household
earnings in all industries plus private household
earnings - Total earnings multiplier table
- Household row entries are private household
earnings - Total value-added table
- Household row entries are private household
earnings because for private households, value
added equals earnings
46Application Example Increase in Household
Expenditures
- Question What is the total impact on a region
of a 1 million increase in payments to civilian
contractors at a military base? - Example will use
- Multipliers for I-O industry code H00000 for the
Columbus GA-AL MSA - Final-demand change of 1 million
47Impact of an Increase in Household Expenditures
48Household Multipliers
49Household Expenditures Calculating Total Output
Impact
50Producers Values vs. Purchasers Values
- Final-demand changes must be in producers' values
instead of purchasers values - Purchased services Purchasers' value is likely
to equal the producers' value - Purchased goods Purchasers' value is not likely
to equal the producers' value - National distribution costs data can be used to
convert purchases in purchasers values to
producers values
Producers Value Purchasers Value
Transportation Costs Wholesale and
Retail Margins
51Application Example Converting Purchasers
Values to Producers Values
- Question What is the total impact on a region
of a 16 million increase in soft drink sales to
consumers outside the region? - Example will use
- Multipliers for the Columbus GA-AL MSA
- 16 million increase in soft drink sales in
purchasers values - Table D Commodity Composition of PCE - RIMS II
Detailed Industries from the Distribution Costs
Tables - Example assumes
- The soft drink manufacturer and the firms
providing truck transportation and wholesale
trade services are located in the region.

56Impact of an Increase in Soft Drink Sales
57Key Points!
- Calculation of impact requires that you know the
location of firms - producing the commodity
- providing transportation and wholesale and retail
trade services - Distributions costs may vary depending on type of
final use (PCE, PES, Govt., etc.) - Make sure to use the appropriate Distribution
Cost table when calculating producer,
transportation, and margin shares
58Hands-on Exercise 2
- In this exercise you will
- Use national distribution costs data to convert a
final-demand change for farm equipment from
purchasers values to producers values - Use a final-demand change in producers values to
estimate the impact for farm equipment
59Hands-on Exercise 2 Assumptions
- Assumptions and information for this exercise
- Final-demand change for farm equipment (I-O
industry code 334220) is 10 million in
purchasers values - Firm producing the farm equipment is located in
the region - Firms providing truck transportation and
wholesale trade services for are located in the
region - National distribution costs data for Private
Investment in Equipment (PES) purchases of farm
equipment - NOTE Worksheets contain the appropriate
multipliers for this exercise.
60Tourism Impact Studies
- No single tourism industry in RIMS II
- Impacts can be estimated using final-demand
changes for the constituent industries (hotels,
retail, etc.) - Do not use a simple average of tourist-related
industry multipliers to calculate impact - Surveys designed to conform to RIMS II industries
will allow for easier impact analysis - Convert purchases in purchasers values to
producers values - Express impacts in terms of annual impacts
61Hands-on Exercise 3
- In this exercise you will
- Estimate the impacts of tourism on a region using
multipliers for constituent industries (hotels,
retail, etc.) - Use national distribution costs data to estimate
trade margins for purchased goods - Use BEAs Local Area Personal Income and
Employment data (tables CA25N and CA05N) to
determine if estimated impacts are reasonable
62Hands-on Exercise 3 Assumptions
- Assumptions and information for this exercise
- Tourists purchases equal 10 million in
purchasers values - Purchased goods not produced in the region (only
the retailer is located in the region) - National distribution costs data for Personal
Consumption Expenditure (PCE) purchases of - Gasoline (I-O industry code 324110)
- Food (Industry code 19)
- Apparel (Industry code 20)
- NOTE Worksheets contain the appropriate
multipliers for this exercise.
63The Bill-of-goods Approach
- Impact estimates can be improved with
bill-of-goods information - Requires estimates of locally purchased inputs
(information provided by the user) - Need to account for wholesale and retail margins
- Calculates the economic impact of each locally
purchased input - Initial change must be added to the impacts
64Intermediate and Fixed Capital Investment
Purchases
- Impacts of intermediate and fixed capital
investment purchases should be evaluated
separately - Intermediate Purchases
- Purchases of goods and services used to produce
other goods and services - Sum of intermediate purchases are sometimes used
as a proxy for a final-demand change - Investment Purchases
- Purchases of structures, equipment, and software
65Application Example Using a Bill-of-goods
Approach
- Question What is the total impact of operating
a sports facility on a region? - Example will use
- The sports facility's purchases of locally
produced goods and services
66Purchases Associated with the Operation of a
Sports Facility
67Using Bill-of-goods Approach to Calculate the
Total Output Impact
68Implied Final-Demand Output Multiplier Using the
Bill-of-goods Approach
69Hands-on Exercise 4
- In this exercise you will
- Estimate the impact of a university using two
approaches - Approach 1 Final-demand change (sum of
intermediate purchases) - Approach 2 Bill-of-goods (regional
non-investment purchases) - Compare the impacts based on these approaches
- Estimate the impacts of universitys fixed
capital investments
70Hands-on Exercise 4 Assumptions
- Assumptions and information for this exercise
- Final-demand change for University services (I-O
industry code 611A00) is 13.5 million in
purchasers values - Sum of intermediate purchases is 13.5 million in
purchasers values - 100 of households employed by the university
reside in the region - Purchased intermediate goods not produced in the
region (only the wholesaler is located in the
region) - Sum of investment purchases is 11.5 million in
purchasers values - Purchased investment goods not produced in the
region (only the wholesaler is located in the
region) - NOTE Worksheets contain the appropriate
multipliers for this exercise.
71Multiplier Relationships
- Final-demand earnings multiplier divided by
direct-effect earnings multiplier will yield an
estimate of the initial change in earnings per 1
final demand - Final-demand employment multiplier divided by
direct-effect employment multiplier will yield an
estimate of the initial change in employment per
1 million final demand
72Application Example Estimating Final-Demand
Using Initial Changes and RIMS II
- Question How do I estimate a change in
final-demand output when I have only an estimate
of the initial change in earnings or employment? - Example will show
- How to use the initial change in earnings or
employment and the RIMS II multipliers to
calculate a change in final-demand output
73A Deeper Look at the Multipliers
- Remember the cookies
- Change in output of cookies 10 million
- Change in number of jobs in cookie manufacturing
32 - Change in earnings in cookie manufacturing
1.4 million
74Earnings-per-Output Cookies Example
Question Why are the earnings impacts
different? Users data may differ from what RIMS
II assumes for the earnings-per-output ratio.

75Employment-per-Output Cookies Example
Question Why are the employment impacts
different? Users data may differ from what RIMS
II assumes for the employment-per-output ratio.

RIMS employment-per-output
76Deriving Final Demand from Multipliers and
Initial Earnings
Final demand
77Deriving Final Demand from Multipliers and
Initial Employment
Final demand
78Key Points!
- RIMS II direct earnings-per-employment
assumptions can be calculated using the RIMS II
multipliers - Output derived using earnings may differ from
output derived using employment - Due to the difference between RIMS II
earnings-per-employment assumptions and actual
user data - Important to use data on the initial changes
(earnings or employment) that is most trustworthy
79Multipliers and Price Indexes
- The model year is 1997 or 2005, depending on the
multiplier series - RIMS II assumes relative prices do not change
- If relative prices have changed substantially
since the model year, the final-demand change
should be deflated - National price indexes can be used to deflate
final-demand change and inflate impacts
80Application Example Inflating or Deflating the
Final-Demand Change
- Question How do I deflate the final-demand
change before multiplying it by the final-demand
multipliers? - Answer
- Use price indexes to deflate the final-demand
change and inflate impacts
81Price Indexes Deflating Final-demand Change
- Deflate final-demand change before using the
multipliers - National Income and Product Account (NIPA) Price
Indexes - Choice of index will depend on type of final user
Where FD? Final-demand change B RIMS II
Year C User Data Year
82Price Indexes Inflating Impacts
- Inflate impacts
- Chain-Type Price Indexes for Gross Output by

83Common Mistakes When Using RIMS II
- Study area defined incorrectly
- Averaging multipliers
- Not converting purchasers values to producers
values - Treating changes in intermediate use as
final-demand changes - Not considering the net impact
- Using multipliers for Other government
enterprises (I-O industry code S00A00) to
estimate impacts of government - Comparing output impacts to Gross Regional
Product (GRP)
