  • Demand Curve

    A graphical representation showing the relationship between price and the quantity consumers are willing to buy at each price.
  • Normal Goods

    Products for which demand increases as consumer income rises, often associated with higher quality or luxury.
  • Inferior Goods

    Items for which demand decreases as consumer income rises, typically considered lower quality or budget options.
  • Substitute Goods

    Products that can replace each other; a price increase in one leads to higher demand for the other.
  • Complementary Goods

    Items usually purchased together; a price increase in one causes demand for the other to fall.
  • Consumer Preferences

    Tastes and trends influencing demand; shifts occur when popularity or desirability of a product changes.
  • Consumer Expectations

    Beliefs about future prices or income that affect current demand, often leading to increased purchases if higher prices are anticipated.
  • Number of Consumers

    The total population of buyers in a market; more buyers generally result in higher demand.
  • Directly Proportional Relationship

    A situation where two variables move in the same direction, such as income and demand for normal goods.
  • Inversely Proportional Relationship

    A scenario where one variable rises as the other falls, like price of complements and demand.
  • Quantity Demanded

    The specific amount of a product consumers are willing to buy at a given price, represented by movement along the curve.
  • Shift to the Right

    An increase in demand, shown as the demand curve moving outward, often due to positive market changes.
  • Shift to the Left

    A decrease in demand, depicted as the demand curve moving inward, usually caused by negative market factors.
  • Advertising

    A tool for increasing the number of consumers by raising awareness and desirability of a product.
