Problem 37
Question
The Cobb-Douglas production function for an automobile manufacturer is \(f(x, y)=100 x^{0.6} y^{0.4}\) where \(x\) is the number of units of labor and \(y\) is the number of units of capital. Estimate the average production level if the number of units of labor \(x\) varies between 200 and 250 and the number of units of capital \(y\) varies between 300 and \(325 .\)
Step-by-Step Solution
Verified Answer
To find the average production level, compute \(f(225, 312.5)=100 * 225^{0.6} * 312.5^{0.4}\).
1Step 1: Understand the Cobb-Douglas production function
The Cobb-Douglas production function is a multiplicative model of production which combines inputs (labor and capital) in order to provide an output. It is given as \(f(x,y)=100 x^{0.6} y^{0.4}\) where \(x\) and \(y\) are input factors, labor and capital respectively.
2Step 2: Substitute the average values of labor and capital
The problem asks for the average production level, so first we need to find the average values for the labor (\(x\)) and capital (\(y\)). The average value for \(x\) is \((200+250)/2=225\) and for \(y\) is \((300+325)/2=312.5\). Then, substitute these values into the Cobb-Douglas production function, we will obtain \(f(225,312.5)=100*(225)^{0.6}*(312.5)^{0.4}\).
3Step 3: Calculate the average production level
Evaluate this expression to find the average level of production. The specific calculation will excute in the next step.
4Step 4: Evaluate The Expression
Perform the mathematical operations to get the result. 100*(225)^{0.6}*(312.5)^{0.4} means multiply 100 by 225 raised to the power of 0.6 and 312.5 raised to the power of 0.4. Then add your results together. The result you get is the average production level.

Average Production Level
In the context of production, estimating the average production level involves finding a typical level of output given a range of inputs. Here, it refers to the output of the automobile manufacturer using specific amounts of labor and capital. We use the Cobb-Douglas production function to calculate this.
To find the average production level, we first identify the midpoints of the given ranges of labor and capital. By averaging 200 and 250, we find the average labor input as 225. Similarly, the average capital input is 312.5, the midpoint of 300 and 325.
These average values are substituted into the production function. It is essential to ensure that you understand this step, as it allows us to identify the expected output under normal conditions for the specified inputs.

Labor and Capital Inputs
Labor and capital are primary inputs in the production process, and their combination determines the output level. In this example, labor (\(x\)) and capital (\(y\)) are combined using specific powers, which represent their contributions to output.
Labor refers to human resources applied in production, ranging from workers to skill level inputs. Capital includes machinery, buildings, and technology. Here, the powers 0.6 and 0.4 on labor and capital indicate their elasticity in production:
Labor refers to human resources applied in production, ranging from workers to skill level inputs. Capital includes machinery, buildings, and technology. Here, the powers 0.6 and 0.4 on labor and capital indicate their elasticity in production:
- Labor's power of 0.6 implies it has a greater impact on output compared to capital.
- Capital’s power of 0.4 suggests it also contributes significantly, though less than labor.
Multiplicative Model of Production
The Cobb-Douglas production function is a classic multiplicative model. It combines inputs by multiplying them each raised to a power, reflecting each input's influence on production. This form enables us to capture the real-world interactions between various inputs.
In the function \(f(x,y) = 100 x^{0.6} y^{0.4}\), the term '100' represents total factor productivity, which is the output level when inputs are optimized. The exponents show the relative contribution of each input.
By using this model, businesses can understand how changes in input values scale up to affect production, offering insights into how best to allocate resources efficiently. Understanding this multiplicative structure is crucial for evaluating different production scenarios.
