Spillover Example

Your neighbor does all the work and pays all the costs of keeping a hive of bees; he, of course, gets the direct benefits of the honey. At the same time, you also indirectly benefit since some of the bees will fly to your yard and pollinate your flowers and vegetables without you lifting a finger and paying a dime. This is a spillover or indirect benefit.

Many public services also provide indirect benefits to non-users of the service. Identifying these indirect benefits and how they result from the direct benefits is the purpose of public value education.
