Examples of Interrelationships Between Sectors:
• Sectors purchase from other sectors
• Sectors sell to other sectors
• Sectors sell outside the local economy
• Sectors buy outside the local economy
• Sectors pay their employees
• Sectors pay taxes

Input-Output Models
• An input/output table quantifies the transactions between sectors in an economy.
• It’s a “snap-shot” of the economy for a one-year period.
• By understanding these linkages, we are able to predict how a change in one sector will affect the other sectors.
• Multipliers can be estimated.

Predictive Use of Input-Output Analysis
• Impacts are tracked throughout the economy
• Multipliers are derived from regional economic accounts
• Only local transactions are used to create the multiplier effect

Multipliers
![Page 9: Input-Output Analysis. Input-Output analysis creates a picture of a regional economy describing flows to and from industries and institutions.](https://reader035.fdocuments.net/reader035/viewer/2022062318/551a9a845503466b3a8b53c6/html5/thumbnails/9.jpg)
What are Multipliers?
Multipliers measure total change
throughout the economy
from a one unit change
for a given sector.
![Page 10: Input-Output Analysis. Input-Output analysis creates a picture of a regional economy describing flows to and from industries and institutions.](https://reader035.fdocuments.net/reader035/viewer/2022062318/551a9a845503466b3a8b53c6/html5/thumbnails/10.jpg)
Multipliers
• Direct effects represent direct or initial spending
• Type I - Direct and indirect effects include the direct spending plus the indirect spending or businesses buying and selling to each other
• Type II - Direct, indirect and induced effects include direct and indirect plus household spending earned from direct and indirect effects
![Page 11: Input-Output Analysis. Input-Output analysis creates a picture of a regional economy describing flows to and from industries and institutions.](https://reader035.fdocuments.net/reader035/viewer/2022062318/551a9a845503466b3a8b53c6/html5/thumbnails/11.jpg)
Multipliers Continued
• Three multipliers are used to describe the economic impact:– Employment– Income (Value-Added)– Output (Receipts)
![Page 12: Input-Output Analysis. Input-Output analysis creates a picture of a regional economy describing flows to and from industries and institutions.](https://reader035.fdocuments.net/reader035/viewer/2022062318/551a9a845503466b3a8b53c6/html5/thumbnails/12.jpg)
Interpretation of Multipliers
• You will often see values for multipliers in the media, the interpretation of these numbers typically causes confusion
Example 1– Type II employment multiplier (Ag) = 2.25
• When the Agricultural Sector realizes a 1 employee change, total employment in the study area changes by 2.25 jobs from direct, indirect and induced effects
![Page 13: Input-Output Analysis. Input-Output analysis creates a picture of a regional economy describing flows to and from industries and institutions.](https://reader035.fdocuments.net/reader035/viewer/2022062318/551a9a845503466b3a8b53c6/html5/thumbnails/13.jpg)
Multipliers Continued
Example 2
Type II Income Multiplier (Ag) = 1.78When the Agricultural Sector realizes a $1.00 change in income, total income in the study area changes by $1.78 from direct and indirect linkages
![Page 14: Input-Output Analysis. Input-Output analysis creates a picture of a regional economy describing flows to and from industries and institutions.](https://reader035.fdocuments.net/reader035/viewer/2022062318/551a9a845503466b3a8b53c6/html5/thumbnails/14.jpg)
Multiplier Cautions (Very Important)
• Multipliers are NOT interchangeable (i.e. employment and value added multipliers are very
different, thus you can’t use one for the other)• Not transferable to other study areas or across
different time periods• No differentiation between full-time and part-time
jobs• Results less certain for new types of economic
activity• They do tend to overstate the impact of change• Take caution for multipliers larger than 3
![Page 15: Input-Output Analysis. Input-Output analysis creates a picture of a regional economy describing flows to and from industries and institutions.](https://reader035.fdocuments.net/reader035/viewer/2022062318/551a9a845503466b3a8b53c6/html5/thumbnails/15.jpg)
IMPLAN Software
• A talented person could probably figure out relationships for a 6 sector economy
• An economy with more than 500 sectors is another story
• IMPLAN software does the work for us and calculates multipliers
• IMPLAN is relatively expensive, hence the need for a partnership with the University
![Page 16: Input-Output Analysis. Input-Output analysis creates a picture of a regional economy describing flows to and from industries and institutions.](https://reader035.fdocuments.net/reader035/viewer/2022062318/551a9a845503466b3a8b53c6/html5/thumbnails/16.jpg)
Pushing the local initiative
• “Kentucky Proud”
• “Buy Local”
• When we keep our money local, the multipliers are larger allowing more money to flow in the local economy, resulting in higher incomes for local residents

Interpretation
• Employment Multiplier: 1.21
For every employee hired in the health sector there are an additional 0.21individuals employed because of indirect and induced effects.
• Output Multiplier:
1.22
For every $1 of sales in the health sector there is an additional $0.22 of revenue generated due to indirect and induced effects

Model Limitations
• Based on a set of assumptions that might restrict the model. Other modeling techniques can be used to provide a range of impacts, not one single number
• Economic impacts should only be part of the discussion. We should not ignore the following:– Quality of Life– Environmental Impacts– Social and Cultural History– Equity ImpactsTHIS IS WHY COMMUNITY INVOLVEMENT IS VITAL
