Economic rent is the difference between what an owner of a factor of production (such as land, capital or labor) receives and the opportunity cost for that owner.
Let's suppose the factor of production is labor. In this example, the laborer receives $20/per hour for their job, and the minimum salary they'd be willing to work for (opportunity cost) is $16/per hour. This $4/hour difference is the laborer's economic rent. In the case of the superstar baseball pitcher, most of the salary earned may be economic rent. Most of a wages of a dishwasher is opportunity cost, since these types of jobs pay minimum wage.If the factor of production is a plot of land, the supply curve would be perfectly vertical, since there is no way for the landowner to supply additional land. In this case, all money received is economic rent.
The size of economic rent received by a owner of a factor of production is determined by the elasticity of supply for that particular good or service.
- If the elasticity of supply is neither elastic nor inelastic, the supply curve will slope upward and the supplier's income would be split between economic rent and opportunity cost.
- If the elasticity of supply is inelastic, the supply curve would be perfectly vertical and the supplier's entire income would be comprised of economic rent. For example, if the supply were a particular plot of land, or a
- If the elasticity of supply is elastic, the supply curve would be perfectly horizontal, and the supplier's entire income would be comprised of opportunity cost.
Look Out! Do not confuse "economic rent" with "rent". The rent paid each month to live in an apartment, or to lease a car is not the same. Remember that economic rent is simply a component of the income received by a supplier of a good or service. |
