Class XI, Principles of Economics, "Quasi Rent"

Quasi Rent

The concept of Quasi rent was first introduced by Marshal according to him, quasi rent is a surplus earned by investments of production other then land. It is the income derived from appliances and machines, which are the product of human effort. Quasi rent stands for whole of the income, which some agents of production yield when demand for them is suddenly increased. It is earned during a period that their supply cannot be increased in response to increase in demand for them. Hence it is a short period concept. It has also been defined as the excess of total revenue earned in the short run over and above the total variable costs.


The concept of quasi rent can be understood with the help of an example. At the time of independence of Pakistan, the demand for houses increased due to sudden increase in population but the supply could not be increased due to the scarcity of building material. The abnormal increase in the return on capital invested in capital (building) is quasi rent.
