1 www.bea.gov RIMS II Regional Input-Output Modeling System Zoë O. Ambargis BEA/PNREAP/University of Nevada Regional Economic Workshop Reno, NV September 29, 2009

2 www.bea.gov 2 What is RIMS II? ▪ Input-output model developed by the BEA in the mid 1970’s ▪ Incorporates linkages among industries in a regional economy ▪ Best suited for analyzing the impacts of small changes in a regional economy

3 www.bea.gov 3 RIMS II Has Been Used to Analyze a Variety of Projects ▪ Opening and closing military bases ▪ Changes in tourism ▪ New energy facilities ▪ Construction of sports facilities ▪ New retail establishments ▪ New airports or port facilities ▪ Opening and closing manufacturing plants ▪ Contribution of universities and hospitals

4 www.bea.gov 4 Framing Your Analysis ▪ What is the project/issue being studied? ▪ What is the change? ▪ What is the magnitude of the change? ▪ What is the timing? ▪ Which industries are affected? ▪ What is the affected region?

5 www.bea.gov 5 Ordering RIMS II Multipliers

6 www.bea.gov 6 Type I and Type II Multipliers ▪ Type I multipliers  Industry impacts only  Total impact = direct + indirect ▪ Type II multipliers  Industry impacts and household expenditure impacts  Total impact = direct + indirect + induced  More commonly used than Type I multipliers

7 www.bea.gov 7 Annual and Benchmark Series ▪ Annual series  2006 national annual I-O data and 2006 regional data  More current, less detailed  60 aggregate industries ▪ Benchmark series  1997 national benchmark I-O data and 2006 regional data  More detailed, less current  473 detailed and 60 aggregate industries

9 www.bea.gov 9 RIMS II Multipliers

10 www.bea.gov 10 Calculating Impacts Using Type II Final-Demand Multipliers

11 www.bea.gov 11 Accessing Your Multipliers

12 www.bea.gov 12 Multiplier Table 1.5

13 www.bea.gov 13 Comparison of Type I and Type II Impacts

14 www.bea.gov 14 Application Example 2

15 www.bea.gov 15 Calculating Impacts Using Type II Direct-Effect Multipliers

16 www.bea.gov 16 Multiplier Table 1.5

17 www.bea.gov 17 Common Mistakes ▪ Defining the study area incorrectly ▪ Averaging multipliers ▪ Treating employment impacts as FTE impacts ▪ 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” to estimate impacts of government ▪ Treating output impacts as Gross Domestic Product (GDP) impacts

18 www.bea.gov 18 2002 Benchmark Update ▪ RIMS II multipliers will be based on  2002 national benchmark I-O data  2007 regional data ▪ Dimensions of tables will change  406 detailed industries (compared to 473)  62 aggregate industries (compared to 60)  21 row industries (compared to 20)
