a)
The question requires us to draw a labor supply curve.
a)
Explanation of Solution
The following curve represents the labor supply curve of the AP students:
Here, the upward-sloping curve S1 represents the supply curve for cars. It is a positively-sloped curve because there is a direct relationship between the price of a product and its quantity supplied.
b)
The question requires us to determine the impact of increased wages on the labor supply curve.
b)
Explanation of Solution
The following graph represents the impact of an increased wage for babysitting on the supply curve of AP students:
When wage increases for babysitting, AP students move towards the babysitting job from teaching jobs. So, the supply of AP students will fall for a teaching job and will cause the supply curve to shift to the left from S1 to S2 as shown in the above figure.
c)
The question requires us to determine the impact of an increasing number of economics students on the labor supply curve
c)
Explanation of Solution
The following graph represents the impact of a higher number of AP students on the supply curve:
An increase in the number of AP students reflects the higher supply of workers in the labor market. An increase in the supply of AP students will shift the supply curve to the right from S1 to S3 as shown in the above figure.

- Explain and evaluate the impact of legislation on the U.S. criminal justice system, specifically on the prison population and its impact on poverty and the U.S. economy. Include significant elements and limitations such as the War on Drugs and the First Step Act.arrow_forwardGiven the following petroleum tax details, calculate the marginal tax rate and explain its significance: Total Revenue: $500 million Cost of Operations: $200 million Tax Rate: 40% Additional Royalty: 5% Profit-Based Tax: 10%arrow_forwardUse a game tree to illustrate why an aircraft manufacturer may price below the current marginal cost in the short run if it has a steep learning curve. (Hint: Show that learning by doing lowers its cost in the second period.) Part 2 Assume for simplicity the game tree is illustrated in the figure to the right. Pricing below marginal cost reduces profits but gives the incumbent a cost advantage over potential rivals. What is the subgame perfect Nash equilibrium?arrow_forward
- Answerarrow_forwardM” method Given the following model, solve by the method of “M”. (see image)arrow_forwardAs 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_forward
- Published 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.
