    • Monopolies can generate monopoly profits.
    • The concurrence monopolistique model assumes that each company can differentiate its product from its competitors.
    • Companies in concurrence monopolistique sell more as demand increases and prices of rivals increase.

    • Symmetric companies should charge the same price and serve an equal portion of the market.
    • The state of the industry can be described by the number of companies and the average price they charge.
    • The number of companies and the average price they charge can be used to determine how the industry will behave.
