We expand upon the tragedy of the commons looking at some possible solutions and measures to conserve resources. External costs are the costs borne by society and the environment emanating from the actions of others. The inverse of an external cost is an external benefit. The most significant example of an external benefit is land value. We look at how land value arises out of population growth and an increase in demand for resources.
Land value is shaped by natural and social factors which is appropriated by landowners.
In addition, we examine how land value tax can be used to capture unearned increases in land value for the common good. Ignoring land value help creates yet another tragedy of the commons.
