Every dollar spent in an area adds to the area's total employment and income.
The impact of the dollars they import into an area is dependent on the degree to which these dollars are respent in the area. If businesses and employees do not spend their income locally, then the impact of the imported dollars on the local economy is greatly diminished. There are various ways to maximize local respending. For example, dollars saved through energy conservation can be respent in the area instead of being used to import energy. Tourism development can both attract new dollars into an area as well as help support local businesses where residents can also shop.
