    Study Notes

    Monopoly Definition and Assumptions

    • A monopoly is a market structure where one firm sells a unique product to many buyers.
    • Entry into the market is restricted, and established firms have advantages over new entrants.
    • Buyers and sellers have complete information regarding prices.

    Assumptions of a Monopoly

    • One firm operates in the market.
    • The firm sells a unique product.
    • Market demand is the firm's demand curve.
    • Buyers accept the firm's price.
    • The firm's demand curve slopes downward.
    • Firm's profit is maximized when marginal revenue (MR) equals marginal cost (MC).
    • Profits or losses can occur in both the short-run and long-run.
    • High barriers to entry exist in the market.

    How Monopolies Arise

    • Monopolies arise due to the absence of close substitutes for the good or service.
    • Barriers to entry prevent other firms from entering the market.

    Price Setter

    • A monopoly is a price setter, meaning it sets the market price based on the market demand curve.
    • Examples include Manitoba Hydro and Canada Post.

    Barriers to Entry

    • Natural barriers to entry occur due to economies of scale.
    • One firm can supply the entire market at the lowest possible price due to a large-scale operation.
    • Legal barriers may restrict competition or entry, such as public franchises, government licenses, patents, and copyrights (e.g., Canada Post, doctors, Big Mac, and a song).

    Monopoly Price-Setting Strategies

    • Single-price monopoly: A firm sells each unit of output for the same price to all customers. An example is De Beers Diamonds.
    • Price discrimination: A firm sells different output units for different prices.

    Monopoly's Output and Price Decisions

    • Price and Marginal Revenue: A monopoly operates on the elastic portion of its demand curve, meaning marginal revenue (MR) is positive.
    • Maximizing Economic Profit: The firm maximizes profit where marginal revenue (MR) equals marginal cost (MC). (MC=MR) This point is on the elastic portion of the demand curve.
    • Graph of Output and Price Decisions: Visual representations are located in the textbook.

    Single-Price Monopoly vs Competition

    • In comparison to perfect competition, monopolies produce less and set higher prices.
    • Graphic representations are available in the textbook.
    • Efficiency comparison: Monopolies result in a loss of consumer surplus due to higher prices and less overall output.

    Redistribution of Surpluses

    • In a monopoly, some of the lost consumer surplus gets transferred to the monopoly firm.
    • The total surplus in the economy is reduced (deadweight loss).
    • This shift of surplus is a redistribution, not a loss to society.

    Rent Seeking

    • Monopolies create deadweight loss (DWL) and are inefficient.
    • The social cost of monopoly is potentially higher than the DWL.
    • Rent seeking is an activity where firms/individuals pursue wealth by capturing economic rent, rather than increasing efficiency.

    Perfect Competition vs Monopoly (Surplus)

    • The graphical comparison of consumer surplus (CS), producer surplus (PS), and deadweight loss (DWL) for perfect competition and monopoly is provided in the textbook.

    Price Discrimination

    • First-degree price discrimination: A firm charges each customer the maximum price they are willing to pay. The firm captures all consumer surplus (Example: car industry)
    • Second-degree price discrimination: A firm charges different prices based on amounts/blocks of output (e.g., Electricity, natural gas).
    • Third-degree price discrimination: A firm charges different prices to different groups based on elasticity (e.g., different ticket prices depending on age or time of day).

    Increasing Profit and Producer Surplus

    • Successful price discrimination allows firms to capture consumer surplus, converting it to producer surplus (PS).
    • Increased PS directly correlates to increased profit.

    Total Revenue in Perfect Price Discrimination

    • Mathematical and graphical representation of total revenue in different price discrimination scenarios are available in the textbook.

    Producer Surplus

    • Mathematical explanations and graphical representations are part of the textbook sections.

    Economic Profit

    • Calculation of economic profit using total revenue and total cost with visual representation are in the source material.

    Monopoly Regulation

    • Regulation involves rules by a government agency to control prices, quantities, or industry operations.
    • Deregulation is the process of removing these rules.
    • Social Interest Theory suggests that regulation reduces inefficiencies and allocates resources effectively.
    • Capture Theory proposes that producers' self-interest influences the regulation to maximize profit.

    Efficient Regulation of a Natural Monopoly

    • Marginal Cost Pricing Rule sets prices equal to marginal costs, causing potential losses for the firm.
    • Average Cost Pricing Rule sets prices equal to average costs (e.g., P=LAC) to eliminate losses.

    Rate of Return Regulation

    • Firms justify their prices based on return on capital, which is limited to pre-determined target rates, and other constraints.

    Price Cap Regulation

    • Price caps are a ceiling for prices, set equal to long run average costs (LRAC).
    • Visual representation available in the textbook.

    Efficiency and Rent Seeking with Price Discrimination

    • Efficiency is impacted by rent seeking behavior, especially in the presence of price discrimination.
