Economic Definition of quasi-rent. Defined.

Term quasi-rent Definition: The payment that is received by a resource of production activity over the opportunity cost in the short run. The notion of quasi-rent is similar to economic rent, or economic profit, which is payment or revenue received over opportunity cost. The key difference is that quasi-rent is a short-run phenomenon. While quasi-rent is "extra" payment received in the short run, such payment might be essential to keep the resource or production activity in the long run. An example is the quasi-rent received due to the patent on a technological innovation. In the short run, the revenue received can be considered as profit in excess of the opportunity cost of production. However, in the long run this extra revenue motivates innovators to develop new technology. Without quasi-rent the innovations would not occur.
