Marginal Cost (MC): It refers to the rate by which the total cost of the produced good changes when the production increases by a single unit. As the fixed cost is constant irrespective of production, so the marginal cost depends on the variable cost only in the short run. Marginal cost is calculated as follows:

Here,

  • EBK ESSENTIALS OF ECONOMICS, Chapter 6, Problem 6P , additional homework tip  6is the marginal cost.
  • EBK ESSENTIALS OF ECONOMICS, Chapter 6, Problem 6P , additional homework tip  7is the change in total cost
  • EBK ESSENTIALS OF ECONOMICS, Chapter 6, Problem 6P , additional homework tip  8is the change in quantity.

Fixed cost: It is a cost which is constant in the short run, it is not related to any change in the production of goods or service, it will be fixed disregarding of an increase or decrease in output.

Marginal Cost: It refers to the additional cost from an additional unit of output. It is generally the additional variable cost.

Average Total Cost: It is also referred as the cost of a single unit, it includes the overall cost, that is the variable cost as well as the fixed cost. A firm should always maintain the price of a product above the ATC, otherwise it will result in loss for the firm. The formula for ATC is:

1. A firm has the following demand function: P = 60 – 0.5Q    and its total cost is defined by TC= 13+ Qa. Find the maximum revenue b. Find the production to optimize the profit. c. Verify if the marginal revenue and marginal cost are the same at the profit-maximizing productionlevel. Exercise 6From the point of view of the firm, what decision criteria have been found relevant in the analysis ofproduction and profit? Provide two refernces with your answer.
5. Some people find options expensive and use more complex structures to reduce the cost. For example, consider buying a call with a strike of $55 and selling a call with a strike of $60. a. What is the cost of establishing this combined position? b. What is the payoff of the combined position if the market price goes to $60? c. What is the payoff of the combined position if the market price goes to $100?
3. An investor has $1,000 to invest. They believe the price of the underlier will increase to $60 within one year. a. How many shares of stock could they buy with the $1,000 at the current price of $50, and how much would they make if the share price increased to $60? b. How many calls with a strike of $55 could they buy for the same $1,000, and how much would they make if the share price increased to $60? c. How much would they make (or lose) from the stock and from the calls if the share price declined to $40? 4. What is the premium on a call with a strike of $0.01? Why is the premium so close to the $50 share price?
