open access resource

Open access resources are goods and services that are rival (they are diminished when exploited by someone) and from which it is difficult to exclude beneficiaries (they are not closed-off, gated, easily charged-for, so that prices can disclose value) and are largely unmanaged, or poorly managed. Open access resources are commonly over-exploited (they are rival) as people are motivated to take what they can, without penalty, therefore, they can be frequently degraded.
