A firm has a patent on a new carbon-capture technology, making it the only producer of that device. The firm is currently earning a positive economic profit and is producing the profit-maximizing level of output.
Draw a correctly labeled graph for the firm and show each of the following.
(i) The quantity of carbon-capture devices produced by the firm, labeled $Q_M$ (ii) The price charged by the firm, labeled $P_M$ (iii) The area representing consumer surplus, shaded completely
The government is considering different options to regulate the firm.
Suppose the government is considering taxing the firm. Could using a per-unit tax change the firm's output to the socially optimal quantity? Explain.
Instead, suppose the government imposes a price ceiling so that the firm produces the socially optimal quantity. On your graph in part (a), label the quantity and price after the price ceiling is imposed as $Q_C$ and $P_C$.
At the price and the quantity identified in part (b)(ii), is the firm earning positive economic profit? Explain.
Assume the government decides not to regulate the firm and instead the firm produces the quantity of output that maximizes total revenue.
If the firm now increases its output by one unit, would marginal revenue be positive, negative, or zero? Explain.
Starting at the total-revenue-maximizing quantity, if the firm reduces the price by 10%, would quantity demanded increase by less than 10%, by more than 10%, or by exactly 10%?
Bueno is a firm that produces and sells guava, a type of fruit. The market for guava is perfectly competitive. The marginal private benefit (MPB), marginal private cost (MPC), marginal social benefit (MSB), and marginal social cost (MSC) curves are illustrated in the graph provided.
[Graph titled "Price per Unit ($)" on the y-axis and "Quantity of Output" on the x-axis. Two upward/downward lines are shown. One line is labeled MPC = MSC, rising from lower-left through the point where it crosses the other line; dashed reference lines mark price levels 8, 7, 5, and 4 on the y-axis. The MPC = MSC line passes through the points (Q_0, 8) and (Q_1, 7). The other line, labeled MSB on its upper portion and MPB on its lower portion, is downward sloping; it passes through the points (Q_0, 5), (Q_1, 7), (Q_1, 4), and (Q_2, 5). The two lines (MPC=MSC and MSB) intersect at the point (Q_1, 7). The x-axis is marked with three quantities in order:$Q_0$,$Q_1$,$Q_2$ (labeled "Quantity of Output").]
Identify the kind of market failure represented by this graph.
Using numbers from the graph, identify the marginal external benefit.
Assume the guava market is in short-run equilibrium and Bueno hires workers in a perfectly competitive labor market at a wage of $20 per hour. The marginal product of the last worker hired was 6 units of guava per hour.
Calculate the change in Bueno's profit per hour from the last worker hired. Show your work.
Suppose that the government decides to provide a per-unit subsidy to consumers who buy guava. How would the per-unit subsidy affect Bueno's marginal revenue product curve? Explain.
Instead of hiring workers in a perfectly competitive labor market, assume Bueno hires workers in a monopsony labor market. Will the number of workers hired increase, decrease, or stay the same? Explain.
In the local market for Good X, there are four individual buyers: Emily, Wu, Omar, and Fernanda. The quantities that each individual buyer would be willing and able to purchase at different prices are included in the table provided.
| Price | Emily | Wu | Omar | Fernanda |
|---|---|---|---|---|
| $1 | 5 | 4 | 4 | 3 |
| $2 | 4 | 3 | 4 | 3 |
| $3 | 4 | 3 | 3 | 2 |
| $4 | 3 | 2 | 3 | 2 |
| $5 | 3 | 2 | 2 | 1 |
| $6 | 2 | 1 | 2 | 1 |
| $7 | 2 | 1 | 1 | 0 |
| $8 | 1 | 0 | 1 | 0 |
(Table title: "Quantity of Good X")
The local market for Good X has a perfectly elastic supply. Draw a correctly labeled graph for the local market for Good X with a market equilibrium price of $5. Label the equilibrium price as$5, and label the equilibrium quantity for the market with a specific value based on the data provided in the table.
Assume the cost of production increases, which causes the price of Good X to increase from $5 to$7.
Calculate the price elasticity of demand for Good X as the price increases from $5 to$7. Show your work.
Identify whether the demand for Good X is elastic, inelastic, or unit elastic in that range of prices.
Could Emily's marginal benefit for the second unit of Good X equal $4.50? Explain.
