Unit 3 Microeconomics Lesson 5 Activity 37 ((exclusive)) Today
To understand Activity 37, one must first understand its place in the typical Microeconomics syllabus. Unit 3 generally covers "Product Markets," focusing on how firms make decisions about production, pricing, and profit.
Once Q* and P* are identified, Activity 37 will ask: "Is the firm making a profit, a loss, or breaking even?"
A frequent challenge in Activity 37 involves graphing the MR curve correctly. If the demand curve is linear, the MR curve will have the same y-intercept but twice the slope. For example, if the demand curve hits the y-axis at $100 and the x-axis at 100 units, the MR curve will hit the x-axis at 50 units. Activity 37 often requires students to plot these coordinates, testing their understanding that selling an additional unit has two effects: adding revenue from the new sale but losing revenue from previous units that now sell at a lower price.
The firm earns zero economic profit (normal profit). While this is more efficient than an unregulated monopoly, it still results in some deadweight loss compared to the socially optimal point.

Unit 3 Microeconomics Lesson 5 Activity 37, titled is a foundational exercise for students learning how governments intervene to correct market failures caused by monopolistic power.
: This maximizes total surplus and eliminates deadweight loss. However, for "natural monopolies" with high fixed costs, this price is often below the Average Total Cost (ATC)
) curves. You are asked to evaluate three specific scenarios: an unregulated monopoly, socially optimal regulation, and fair-return regulation. To understand Activity 37, one must first understand
While I cannot reproduce the copyrighted worksheet, I can reconstruct the structure of questions you will encounter. Use this as a practice blueprint.
: The firm produces more than an unregulated monopoly but less than the socially optimal amount.
) keeps the firm in business without subsidies but leaves some inefficiency in the market. If the demand curve is linear, the MR
If you have searched for you are likely in the midst of an Advanced Placement (AP) or college-level introductory microeconomics course. By Unit 3, you’ve already mastered supply and demand, elasticities, and consumer behavior. Now, you are entering a critical juncture: the transition from perfectly competitive market models to the messy, real-world phenomenon of market failure .
. However, because the monopolist faces the entire market demand curve, they must lower the price of all units to sell one more, causing cap M cap R to be less than the price ( ). This results in a higher price ( cap P sub m ) and a lower quantity ( cap Q sub m ) than what is socially optimal, leading to deadweight loss and allocative inefficiency. Regulating the Monopolist
