Economic development is also about increasing the velocity of "Neutral Money" that circulates within the economy. When economists talk about a multiplier effect, they are referring to the circulation of Neutral Money within the economy.
Finally, economic development involves "plugging leaks". That means reducing the flow of money (we can call this "bad Money") from the economy.
Increasingly, communities are taking a more balanced, integrated approach of economic development that includes all three flows. (After all, there are no bright lines segregating these flows.)
