    Study Notes

    Market Structure

    • A single seller with considerable power over pricing and output decisions characterizes a monopoly market structure.
    • The main factor that determines market structure is the number of firms in the market.
    • A monopoly market structure offers the greatest potential control over price.
    • An oligopoly market structure is characterized by a relatively small number of firms supplying the market.
    • In a perfectly competitive market structure, sellers and buyers have a strictly homogeneous product, and no single producer is large enough to influence market prices.
    • The main difference between perfect competition and monopolistic competition is the presence of product differentiation in monopolistic competition.

    Market Characteristics

    • A monopolistic competition market structure is characterized by a large number of firms, each producing a differentiated product.
    • In a perfectly competitive market structure, long-run profits are driven down by the forces of competition.
    • A monopoly market structure allows for the possibility of large profits even in the long run.
    • A firm's profitability in the long run is determined by its cost structure and the market structure.

    Types of Market Structure

    • The four types of market structure are perfect competition, monopolistic competition, oligopoly, and monopoly.

    Market Definition

    • A market is a place where buyers and sellers interact to exchange goods and services.

    Perfect Competition

    • A characteristic of perfect competition is the presence of a large number of firms, each producing a homogeneous product.
    • An example of a perfectly competitive market is the agricultural market.

    Income Elasticity of Demand

    • Income elasticity of demand measures the responsiveness of demand to changes in income.
    • For normal goods, income elasticity of demand typically behaves positively, meaning that an increase in income leads to an increase in demand.
    • A negative income elasticity of demand indicates that a good is inferior, meaning that an increase in income leads to a decrease in demand.
    • An increase in income shifts the demand curve for a normal good to the right.

    Cross-Price Elasticity of Demand

    • Cross-price elasticity of demand measures the responsiveness of demand to changes in the price of a related product.
    • The formula for cross-price elasticity of demand is (ΔQx / Qx) / (ΔPy / Py).
    • Cross-price elasticity of demand is considered positive when an increase in the price of one good leads to an increase in demand for another good.
    • Examples of substitutes based on their cross-price elasticity of demand are coffee and tea.
    • Cross-price elasticity of demand is considered negative when an increase in the price of one good leads to a decrease in demand for another good.
    • Examples of complements based on their cross-price elasticity of demand are cars and gasoline.
    • A negative value of cross-price elasticity of demand indicates that two goods are complements.
    • A positive value of cross-price elasticity of demand indicates that two goods are substitutes.

    Price Elasticity of Demand

    • When εP > 1, an increase in price leads to an increase in total revenue.
    • When 0 < εP < 1, an increase in price leads to a decrease in total revenue.
