Quasi rent is a result of :

Question

Accepted Answer

The correct option is 2:
Quasi-rent, a concept coined by Alfred Marshall, refers to the earnings above the total variable cost that a factor of production receives during the short run. In the short run, capital equipment and other fixed factors cannot be easily changed or reproduced, making their supply temporarily fixed. Therefore, quasi-rent is the surplus earned by these temporarily fixed factors whose supply cannot be increased immediately in response to a rise in demand. While true economic rent is a return to a factor whose supply is perfectly inelastic (like land), quasi-rent is a temporary surplus similar to rent, which disappears in the long run when the supply of the fixed factor can be adjusted. Costs can be broadly categorized as Primary (direct or variable costs) and Secondary (overhead or fixed costs). Since quasi-rent is the return earned *over* variable costs by the *fixed* factors, it is conceptually linked to the secondary (fixed) costs of production.

The incorrect option is 1:
Long run is the period where all factors of production are variable, and the supply of capital equipment can be adjusted to meet demand. Therefore, any temporary surplus like quasi-rent disappears in the long run as competition eliminates excess profits, and returns stabilize to normal profit.

The incorrect option is 3:
Primary costs are typically variable costs, such as the cost of raw materials or direct labor. Quasi-rent is defined as the total revenue minus the total *primary* (variable) costs, meaning it is the surplus earned *over* primary cost, not the result of the primary cost itself.

The incorrect option is 4:
Variable factors are inputs whose quantity can be easily changed in the short run (e.g., raw materials, energy). These factors do not earn quasi-rent because their supply can quickly respond to changes in demand, and thus their earnings tend towards their opportunity cost, eliminating any temporary surplus.
