To plot:
Graphical representation of isoquant and quantity of K and L.
a

Explanation of Solution
Since q = 40,000 has been produced with
In the above diagram, x-axis measures labor while y-axis measures capital, q represents isoquant of Large Mowers as depicted above.
Introduction:
Isoquant curve is a graphical representation showing the same level of output production with different combinations of inputs.
b)
To plot:
Graphical function of isoquant for small mower.
b)

Explanation of Solution
This diagram shows the plotting of q = 40,000, K = 8 and L = 8
In the above diagram, x-axis measures labor while the y-axis measures capital. Q represents isoquant of Small Mowers as depicted above.
Introduction:
Expansion path is a combination of optimal output when input changes due to prices.
c)
To know:
Quantities of K and L for different lawn divisions.
c)

Explanation of Solution
Production functions are given below:
When lawn is cut by 1st method:
When lawn is cut by 2nd method:
Total capital requirement = 9
Total labor requirement = 6.5
Production functions are given below:
When lawn is cut by 1st method:
When lawn is cut by 2nd method:
Total capital requirement = 9.5
Total labor requirement = 5.75
The fraction of K and L means the amount of capital input used per unit of labor.
This table shows the resources uses in the Large Mowers and Small Mowers.

Explanation of Solution
Calculation of labor and capital when 40000 square foot of lawn is cut by 1st method with p fraction.
Calculation of labor and capital when (1-p) fraction of 40,000 square foot lawn is cut by 2nd method.
Calculation of labor requirement:
Calculation of total capital requirement:
Two equations are given as follows:
Solving first equation for p and putting the value of p in second as shown below:
The Table shows the different calculations of Labor (L) and capital (K) in Small Mowers as shown below:
40,000 sq.ft. | LM | |
LM/SM mix | L | K |
0/100$% | 8 | 8 |
25%/75% | 7.25 | 8.5 |
50%/50% | 6.5 | 9 |
75%/25% | 5.75 | 9.5 |
100%/0% | 5 | 10 |
Following graph is plotted from the given table shows the isoquant for the combined production function as shown below:
In the above diagram, x-axis measures labor while y-axis measures capital, q represents isoquant for the combined production function as depicted above.

EBK MICROECONOMIC THEORY: BASIC PRINCIP
- As indicated in the attached image, U.S. earnings for high- and low-skill workers as measured by educational attainment began diverging in the 1980s. The remaining questions in this problem set use the model for the labor market developed in class to walk through potential explanations for this trend. 1. Assume that there are just two types of workers, low- and high-skill. As a result, there are two labor markets: supply and demand for low-skill workers and supply and demand for high-skill workers. Using two carefully drawn labor-market figures, show that an increase in the demand for high skill workers can explain an increase in the relative wage of high-skill workers. 2. Using the same assumptions as in the previous question, use two carefully drawn labor-market figures to show that an increase in the supply of low-skill workers can explain an increase in the relative wage of high-skill workers.arrow_forwardPublished in 1980, the book Free to Choose discusses how economists Milton Friedman and Rose Friedman proposed a one-sided view of the benefits of a voucher system. However, there are other economists who disagree about the potential effects of a voucher system.arrow_forwardThe following diagram illustrates the demand and marginal revenue curves facing a monopoly in an industry with no economies or diseconomies of scale. In the short and long run, MC = ATC. a. Calculate the values of profit, consumer surplus, and deadweight loss, and illustrate these on the graph. b. Repeat the calculations in part a, but now assume the monopoly is able to practice perfect price discrimination.arrow_forward
