Without proper management, a community's material resources may be depleted or rendered unusable. The common pool problem is an economic situation which exists when goods are rival, but non-exclusive (See common-pool resource). Since these resources are owned in common, individuals have no private incentive to preserve them, but rather will seek to exploit them before others can derive benefit. The classic example is of fish in the ocean. Anybody can harvest fish, but a fish that has been caught cannot be caught by another fisherman. Therefore fishermen will seek to maximize their personal profit by catching as many fish as possible, which will ultimately lead to the stock being depleted. It is similar to the free rider problem in that those who do not contribute to the resource may use it without penalty, but the common pool problem is usually considered an economic "problem" since it will eventually lead to the exhausting of a resource. Yet another example of the common pool problem involves the shared use of limited internet bandwidth, such as in a university network, when the connectivity of all users is slowed by the heavy usage of a few.
Elinor Ostrom and Oliver E. Williamson won the 2009 Nobel prize in economic science for work in this area, where they suggested that with good community management of shared resources, as found in successful firms, the "tragedy of the commons" can be avoided.

Famous quotes containing the words common, pool and/or problem:
“If we dreamed the same thing every night, it would affect us much as the objects we see every day. And if a common workman were sure to dream every night for twelve hours that he was a king, I believe he would be almost as happy as a king who should dream every night for twelve hours on end that he was a common workman.”
—Blaise Pascal (1623–1662)
“Just getting in the pool for seven straight hours is unbearable to me.... It’s grueling. There’s nothing physically pleasurable about it. If you’re doing a hard workout, you’re throwing up in the gutter. At night you cling to your pillow and just hope that your body revives before you have to go back and do it again.”
—Diana Nyad (b. 1949)
“I tell you, sir, the only safeguard of order and discipline in the modern world is a standardized worker with interchangeable parts. That would solve the entire problem of management.”
—Jean Giraudoux (1882–1944)
