What is Marginal Revenue Product?
Marginal revenue product (MRP) measures the additional revenue generated by employing one more unit of a variable input, such as labor. It represents the incremental revenue earned for each additional unit of input utilized in the production process. Understanding MRP is crucial for businesses as it helps them optimize resource allocation and maximize profits.
How to Calculate Marginal Revenue Product (MRP)
Formula for MRP
The formula for calculating MRP is:
MRP = ΔTR / ΔQ
where:
- ΔTR is the change in total revenue
- ΔQ is the change in quantity of variable input
Steps to Calculate MRP
To calculate MRP, follow these steps:
- Determine the change in total revenue (ΔTR): Calculate the difference in total revenue between two output levels, each produced using differing quantities of the variable input.
- Determine the change in quantity of variable input (ΔQ): Find the difference in the quantity of variable input used between the two output levels.
- Divide ΔTR by ΔQ: This will give you the MRP.
Applying Marginal Revenue Product
Profit Maximization
Firms aim to maximize profits by producing the output level where MRP equals marginal factor cost (MFC), the cost of employing an additional unit of variable input. At this point, the additional revenue generated by the extra input unit offsets the cost of hiring it.
Resource Allocation
MRP helps businesses determine the optimal combination of inputs to use in the production process. By comparing MRP with MFC for different inputs, firms can allocate resources efficiently.
Input Substitution
MRP allows firms to analyze the impact of substituting one input for another. They can determine whether switching to a cheaper input with a lower MRP but also a lower MFC would be beneficial.
Table of MRP Calculations
| Variable Input | Change in Quantity (ΔQ) | Change in Total Revenue (ΔTR) | Marginal Revenue Product (MRP) |
|---|---|---|---|
| Labor | 1 unit | $100 | $100 |
| Labor | 1 unit | $75 | $75 |
| Capital | 1 unit | $50 | $50 |
| Capital | 1 unit | $25 | $25 |

FAQ about Marginal Revenue Product
What is marginal revenue product (MRP)?
MRP measures the additional revenue earned by employing one more unit of a variable input, such as labor.
How to calculate MRP from total revenue (TR)?
MRP = ΔTR / ΔQ, where ΔTR is the change in total revenue and ΔQ is the change in the quantity of input used.
How to calculate MRP from marginal revenue (MR)?
MRP = MR * ΔQ, where ΔQ is the change in the quantity of input used.
What is the difference between MRP and marginal cost (MC)?
MRP measures the revenue generated by an additional unit of input, while MC measures the cost of producing an additional unit of output.
What is the relationship between MRP and profit maximization?
Profit is maximized when MRP equals MC.
What is the law of diminishing MRP?
As the quantity of input used increases, MRP decreases, assuming other inputs are held constant.
Can MRP be negative?
Yes, if the additional unit of input reduces total revenue.
How to interpret a negative MRP?
A negative MRP indicates that using more of the input will reduce revenue.
What are the limitations of using MRP for decision-making?
MRP is calculated based on marginal changes and may not accurately reflect the impact of large changes in input use.
Is MRP the sole determinant of optimal input use?
No. Other factors such as fixed costs, budget constraints, and market conditions should also be considered.
