    Study Notes

    Overview of Different Market Types

    • Perfect Competition: Many buyers and sellers, non-differentiated good, no barriers to entry, price taker.
    • Monopoly: One seller, many buyers, barriers to entry (natural, legal ownership), price setter.
    • Monopolistic Competition: Many buyers and sellers, differentiated good, no barriers to entry, firms compete on product quality, price, and marketing.
    • Oligopoly: Few sellers, many buyers, barriers to entry, incentive to collude/form a cartel.

    Firms in Different Market Types

    • Perfect Competition: MR = MC, but firms must take the market price, MR = Market Price (MP) = MC, maximizes welfare.

    Monopoly

    • Wants to sell the quantity that maximizes profit (Q where MR = MC) and sells at that price (from demand curve).

    Monopolistic Competition

    • Similar to monopoly, but the difference between MC and P is called the "markup."

    Oligopoly

    • Similar to monopoly; firms can set prices independently or collude.

    Price and Output in Monopolistic Competition

    • Firms in monopolistic competition operate with positive markup and at a point where ATC is not at the lowest (excess capacity).

    Price and Output in Perfect Competition

    • In perfect competition, there is no excess capacity and no markup. All firms still make the same choice (MR = MC).

    Cost Relationships (Key Formulas)

    • TC = TVC + TFC
    • ATC = AVC + AFC
    • TC/Q = ATC → TC = ATC * Q
    • TVC/Q = AVC → TVC = AVC * Q
    • TFC/Q = AFC → TFC = AFC * Q

    Questions from the Class

    • (Specific questions from the class are not included in the extracted text.)

    Technological Efficiency

    • Technological efficiency means using the fewest inputs to produce a given output; it's not just the sum of total inputs (labor/capital), but each specific input.

    Consumer and Producer Surplus

    • Information for calculating consumer and producer surplus, including a demand and supply schedule, is provided.

    Price Ceiling of $4

    • Calculation and analysis of deadweight loss (DWL) given a price ceiling of $4.

    Utility Maximizing Consumption Bundle

    • Jake's budget for iTunes downloads and coffee, information about utility, and determining his utility-maximizing bundle. Includes price lists/schedules.

    Price Discrimination

    • Definition: Monopolists charge different prices to different people for the same good (to capture consumer surplus.)
    • Tips: Practice elasticity and short answer questions for the homework review.

    Homework Review and Questions

    • Questions from HW #1, #2, #3, and #4 cover various concepts related to different economic theories.

    Midterm Exams Review

    • Review for Midterm #1 covers comparative advantage and total changes in quantity/price in equilibrium.
    • Review for Midterm #2 covers political equilibrium, non-excludable and rivalrous goods, and excludable and non-rivalrous goods.
