Introduction
Crowding out refers to the phenomena that within peer production projects in particular, and volunteering in general, paying those volunteers actually diminishes their motivation and might destroy the dynamic of peer production projects.
More generally, see our entry on Intrinsic vs. Extrinsic Motivation, extrensic motivation will crowd out intrinsic motivation.
It may also refer to the related issue that giving power to experts may weaken the motivation on non-experts.

"Offering financial rewards for contributions to online communities basically means mixing external and intrinsic motivation. Since that is an issue widely discussed in the academic world, I will present some interesting examples of an effect called crowding occuring in this context.
Circumstantial Evidence
Basic intuition tells us that we are more willing to undertake a task if we can expect a reward. But there are a number of specific situations where the undermining effect of external incentives is also just as easily understood. A good example is children who are paid by their parents for mowing the family lawn. Once they expect to receive money for that task, they are only willing to do it again if they indeed receive monetary compensation. The induced unwillingness to do anything for free may also extend to other household chores. The reward need not be monetary in the first place. Take the case of a gifted child in violin class. Once ‘gold-stars’ were introduced as a symbolic reward for a certain amount of time spent practicing the instrument, the girl lost all interest in trying new, difficult pieces. Instead of aiming at improving her skills, her goal shifted towards spending time playing well-learned, easy pieces in order to receive the award (Deci with Flaste 1995). This crowding effect may also work the other way round. A patient found it difficult taking her medication for hypertension regularly. Her doctor’s frequent reminders, admonishments, or plain warnings concerning the possible dire consequences had no effect. Despite ending up in the emergency room a couple of times, the patient only managed to alter her behavior when a new doctor - instead of pressuring her to take the medication - discussed with her what time of the day she considered best for taking her pills. Suddenly, she managed to follow the prescription, as her own (intrinsic) motivation was recognized and thereby reinforced.
