BURTON WEISBROD, ECONOMICS DEPT., NORTHWESTERN UNIV. There is often interest in Assessing the local or regional Economic Impacts of a project, program or policy. However, Economic Impacts are easily misrepresented. This primer explains the fundamental options and tradeoffs involved in selecting the right kind of techniques for Assessing Economic Impacts , and explains how to match the appropriate methods to different kinds of applications or situations.

2 1. WHAT ARE Economic Impacts ? Economic Impacts are effects on the level of Economic activity in a given area. They may be viewed in terms of: (1) business output (or sales volume), (2) value added (or gross regional product), (3) wealth (including property values), (4) personal income (including wages), or (5) jobs. Any of these measures can be an indicator of improve- ment in the Economic well-being of area residents, which is usually the major goal of Economic development efforts. The net Economic impact is usually viewed as the expansion or contraction of an area's economy, resulting from changes in ( , opening, closing, expansion or contraction of) a facility, project or program.

3 Sometimes there is also interest in Assessing the Economic impact of an already existing facility or project. This is usually viewed in terms of the jobs, income and/or business sales that are directly or indirectly supported by the facility or project. Such measures actually represent the gross effect -- , the facility's or project's role in (or contribution to) the area economy. That is not necessarily the same as the net impact , particularly if other activities would be expect- ed to enter or expand in the absence of this facility or project.

4 Economic Impacts are different from the valuation of individual user benefits of a particular facility or service, and they are also different from broader social Impacts . The user benefits and social Impacts may include the valuation of changes in amenity or quality of life factors (such as health, safety, recreation, air or noise quality). Yet while these various types of benefits and Impacts may be valued in Economic (money). terms, through studies of individuals' or society's "willingness to pay" for improving them, they are not Economic Impacts (as defined above) except insofar as they also affect an area's level of Economic activity.

Economic Impacts also lead to fiscal Impacts , which are changes in government revenues and expenditures. Economic Impacts on total business sales, wealth or personal income can affect government revenues by expanding or contracting the tax base. Impacts on employment and associated population levels can affect government expenditures by changing demand for public services. Yet while they are related, fiscal Impacts are not the same as Economic Impacts .

6 2. HOW SHOULD Economic Impacts BE MEASURED? Alternative Measures. The various measures of Economic Impacts have very different interpretations: Total employment reflects the number of additional jobs created by Economic growth. This is the most popular measure of Economic impact because it is easier to comprehend than large, abstract dollar figures. However, job counts have two major limitations: (1) they don't necessarily reflect the quality of employment opportunities, and (2) they cannot be easily compared to the public costs of attracting those jobs (through subsidies, tax breaks or public investments).

7 Aggregate personal income rises as pay levels rise and/or additional workers are hired. Either or both of these conditions can occur as a result of business revenue growth. As long as nearly all of the affected workers live in the study area, this is a reasonable measure of the personal income benefit of a project or program. However, it is still an under-estimate of the true income impact , insofar as there is also some net business income (profit) generated that may be paid out as dividends to local business owners or else reinvested locally in buildings, equipment or labor training-- thus further improving the Economic base of the area.

8 Value Added (which is normally equivalent to Gross Domestic Product or Gross Regional Product) is a broader measure of the full income effect. This measure essentially reflects the sum of wage income and corporate profit generated in the study area. However, in today's increasingly global economy, value added can be an over-estimate of the true income impact on a local area, insofar as it includes all business profit generated there -- including that paid out as dividends to owners of the business who do not reside in the study area, and that which is reinvested in corporate facilities outside of the study area.

9 Thus, while value added is the most appropriate measure of impact on overall Economic activity in a geographic area, the personal income (wage) measure is often preferred as a more conservative measure of income benefit to residents of the area. Business Output (also referred to as revenue or sales volume) is the broadest measure of Economic activity, as it generates the largest numbers. It includes the full (gross) level of business revenue, which pays for costs of materials and costs of labor, as well as generating net business income (profits).

Property Values are also a reflection of generated income and wealth. However, it would be double counting to add property value Impacts to income or value added Impacts .
