 | | Economic history is the study of economic change, and of economic phenomena in the past. |
 | | In mainstream market economics, where there are significant scarcities not factored into price, there is said to be an externalization, which is a cost or benefit to actors other than the buyer and seller, of which many examples exist, including pollution (a cost to others) and education (a benefit to others). |
 | | Market economics predicts that scarce goods which are under-priced because of externalities are over-consumed (See social cost), and that scarce goods that are over-priced are under-consumed. |
