Externality

This is a result of industrial or commercial activity which affects other parties without this being reflected in market prices. It is used to refer to the cost or benefit received by a third party. In a externality situation, the third party has no control over the creation of the cost or benefits.

Roads maintained with tax on gasoline has no externality. This is because the tax is imposed on the road users through tax. There is no third party benefiting or incurring cost from the maintenance of of road with tax on gasoline.

people could go to church and listen to the teachings, but it was absolutely forbidden to own and/or read the books of both the old and new testaments. it was also prohibited to translate the books (which where originally in biblical hebrew) to any other language.

this was done so the church could remain in control of what their teachings were and to enhance their importance and power, while also being able to judge people's actions through information that was unavailable for the general public.
