Talk:Rent
From the fallible Wikipedia:
http://Wikipedia.org/wiki/Renting Renting is an agreement where a payment is made for the temporary use of a good or property owned by another person or company.
http://Wikipedia.org/wiki/Economic_rent Economic rent is the difference between what a factor of production is paid and how much it would need to be paid to remain in its current use.
http://Wikipedia.org/wiki/Profit Pure economic profit is the increase in wealth that an investor has from making an investment, taking into consideration all costs associated with that investment including the opportunity cost of capital. Accounting profit is the difference between price and the costs of bringing to market whatever it is that is accounted as an enterprise (whether by harvest, extraction, manufacture, or purchase) in terms of the component costs of delivered goods and/or services and any operating or other expenses. (emphasis added)
By these (arbitrary) definitions, "rent" includes the real Costs of Physical sources, and may or may not include "Economic rent" (Profit).
I think Pasquinelli, Matteo is equating Profit with "Economic rent" because the more broad term "rent" usually includes both real Costs AND Price above cost.
