Consider a firm facing conventional production technology. The short run Production
Function has a small range of increasing marginal product (increasing marginal returns) and
then is subject to the Law of Diminishing Marginal Product (diminishing marginal returns).
A. Putting quantity on the horizontal axis and dollars on the vertical axis, depict three
important curves: Fixed Cost (FC), Variable Cost (VC), and Total Cost (TC). (Note that we
are not asking you to depict average cost functions!)
B. Please clearly indicate on this graph the range of quantities where the firm is experiencing
(1) increasing marginal product and (2) diminishing marginal product.
C. In a few sentences, please justify why you've made this specific classification of
increasing/diminishing marginal product in part (b).
please answer the following questions:
What is money, and why does anyone want it?
Explain the concept of the opportunity cost of holding money .
Explain why an increase in U.S. interest rates relative to UK interest rates would affect the U.S.-UK exchange rate.
Suppose that a person’s wealth is $50,000 and that her yearlyincome is $60,000. Also suppose that her money demand functionis given by Md = $Y10.35 - i2Derive the demand for bonds. Suppose the interest rate increases by 10 percentage points. What is the effect on her demand for bonds?b. What are the effects of an increase in income on her demand for money and her demand for bonds? Explain in words

The graph shows the average total cost (ATC) curve, the
marginal cost (MC) curve, the average variable cost (AVC)
curve, and the marginal revenue (MR) curve (which is also
the market price) for a perfectly competitive firm that
produces terrible towels. Answer the three questions,
assuming that the firm is profit-maximizing and does not shut
down in the short run.
What is the firm's total revenue?

- 1. Suppose that the two nations face the following benefits of pollution, B, and costs of abatement, C: BN = 10, Bs = 7; CN = 5, Cs = 4. Further assume that if the nation chooses to abate pollution, it still receives the benefits of pollution but now must pay the cost of abatement as well. a. Identify the payoffs that accrue to each nation under the four different possible outcomes of the game and present these payoffs in the normal form of the game. b. Recall that the term dominant strategy defines the condition that a player in a game would prefer to play that strategy (in this case either pollute or abate) regardless of the strategy chosen by the other player in the game. Does either nation have a dominant strategy in this game? If so, what is it? c. Identify the Nash equilibria, or non-cooperative equilibria, of this game.arrow_forwardagrody calming Inted 001 and me 2. A homeowner is concerned about the various air pollutants (e.g., benzene and methane) released in her house when she cooks with natural gas. She is considering replacing her gas oven and stove with an electric stove comprising an induction cooktop and convection oven. The new appliance costs $900 to purchase and install. Capping the old gas line costs an additional $150 (a one-time fee). The old line must be inspected for leaks each year after capping, at a cost of $35 for each inspection. a. If the homeowner plans to remain in the house for four more years and the discount rate is 4%, what is the minimum present value of the benefits that the homeowner would need to experience for this purchase to be justified based on its private net sub present value? b. While trying to understand how she might express the value of reduced exposure to indoor air pollutants in dollar terms, the homeowner consulted the EPA website and found estimates provided by…arrow_forwardAfter the ban is imposed, Joe’s firm switches to the more expensive biodegradable disposable cups. This increases the cost associated with each cup of coffee it produces. Which cost curve(s) will be impacted by the use of the more expensive biodegradable disposable cups? Why? Which cost curve(s) will not shift, and why not? Please use the table below to answer this question. For the second column (“Impacted? If so, how?”), please use one of the following three choices: No shift; Shifts up (i.e., increases: at nearly any given quantity, the cost goes up); or Shifts down (i.e., decreases: at nearly any given quantity, the cost goes down). $ Cost Curve Impacted? If so, how? Explanation of the Shift: Why or Why Not AFC No shift. Fix costs stay the same, regardless of quantity. Fixed cost is calculated as Fixed Cost/Quantity. Since fixed costs remain unchanged, AFC stays the same for each quantity. MC Shifts up. Since the biodegradable cups are more expensive, the…arrow_forward
- Styrofoam is non-biodegradable and is not easily recyclable. Many cities and at least one state have enacted laws that ban the use of polystyrene containers. These locales understand that banning these containers will force many businesses to turn to other more expensive forms of packaging and cups, but argue the ban is environmentally important. Shane owns a firm with a conventional production function resulting in U-shaped ATC, AVC, and MC curves. Shane's business sells takeout food and drinks that are currently packaged in styrofoam containers and cups. Graph the short-run AFC0, AVC0, ATC0, and MC0 curves for Shane's firm before the ban on using styrofoam containers.arrow_forwardd-farrow_forwarda-c pleasearrow_forward

What is the net benefit to society of moving from the unregulated emissions level to the efficient level? In response to industry complaints about the costs of the tax, a cap-and-trade program is proposed. The marginal abatement cost curves for the two firms are given by: MAC=24-E and MAC2 = 24-2E2. d. How could a cap-and-trade program that achieves the same level of emissions as the tax be designed to reduce the costs of regulation to the two firms?arrow_forwardOnly #4 please, Use a graph please if needed to help provearrow_forward
- a-carrow_forwardFor these questions, you must state "true," "false," or "uncertain" and argue your case (roughly 3 to 5 sentences). When appropriate, the use of graphs will make for stronger answers. Credit will depend entirely on the quality of your explanation. 1. If the industry facing regulation for its pollutant emissions has a lot of political capital, direct regulatory intervention will be more viable than an emissions tax to address this market failure. 2. A stated-preference method will provide a measure of the value of Komodo dragons that is more accurate than the value estimated through application of the travel cost model to visitation data for Komodo National Park in Indonesia. 3. A correlation between community demographics and the present location of polluting facilities is sufficient to claim a violation of distributive justice. olsvrc Q 4.
