    Study Notes

    Circular Flow of Income with Two-Sector Model

    • The circular flow of income represents expenditure by firms to purchase factors of production, used as inputs to produce goods and services.
    • The two-sector model consists of households and firms interacting in two markets: product market and factor market.
    • In the product market, firms sell goods and services to households, and in the factor market, households sell factors of production to firms.

    Circular Flow of Income with Three-Sector Model

    • The three-sector model involves the government, which has legal and political power to control or influence households, firms, and markets.
    • The government provides public goods and services to society.
    • The three economic agents (households, firms, and government) interact in two markets: product market and factor market.

    Demand

    • The demand for a product is influenced by many factors, including:
    • Price of the product
    • Taste or preference of consumers
    • Income of consumers
    • Price of related goods
    • Consumers' expectations of income and price
    • Number of buyers in the market
    • A change in any of these factors, except the price of the good, will change the demand, causing a shift in the demand curve.
    • A change in the price of the good, while keeping other factors constant, will result in a movement along the same demand curve.

    Determinants of Demand

    • Price of the product
    • Taste or preference of consumers
    • Income of consumers
    • Price of related goods
    • Consumers' expectations of income and price
    • Number of buyers in the market

    Changes in Demand

    • A change in demand will shift the demand curve from its original location.
    • If buyers choose to purchase more at any price, the demand curve shifts rightward (an increase in demand).
    • If buyers choose to purchase less at any price, the demand curve shifts leftward (a decrease in demand).

    Market Supply

    • Market supply is derived by horizontally adding the quantity supplied of the product by all sellers at each price.
    • The supply of a particular product is determined by:
    • Price of inputs (cost of inputs)
    • Technology
    • Prices of related goods
    • Sellers' expectations of price of the product
    • Taxes and subsidies
    • Number of sellers in the market
    • Weather, etc.

    • Sellers' expectations of price of the product
    • Taxes and subsidies
    • Number of sellers in the market
    • Weather, etc.

    Types of Goods

    • Normal good: a good for which the demand increases with increases in income
    • Inferior good: a good for which the demand tends to fall with an increase in the income of the consumer
    • Substitute goods: goods that satisfy the same type of demand and can be used in place of one another
    • Complementary goods: goods that are used jointly or together
    • Giffen goods: goods whose demand falls with a fall in their prices
