    Calculating the Price Elasticity of Demand

    When percentage change in quantity demanded is equal to change in price the demand curve is?
    Figure 1: The price elasticity of demand is calculated as the percentage change in quantity divided by the percentage change in price.

    What Is Quantity Demanded?

    Quantity demanded is a term used in economics to describe the total amount of a good or service that consumers demand over a given interval of time. It depends on the price of a good or service in a marketplace, regardless of whether that market is in equilibrium.

    The relationship between the quantity demanded and the price is known as the demand curve, or simply the demand. The degree to which the quantity demanded changes with respect to price is called the elasticity of demand.

    Key Takeaways

    • In economics, quantity demanded refers to the total amount of a good or service that consumers demand over a given period of time.
    • Quantity demanded depends on the price of a good or service in a marketplace.
    • The price of a product and the quantity demand for that product have an inverse relationship, according to the law of demand.

    Understanding Quantity Demanded

    Inverse Relationship of Price and Demand

    The price of a good or service in a marketplace determines the quantity that consumers demand. Assuming that non-price factors are removed from the equation, a higher price results in a lower quantity demanded and a lower price results in higher quantity demanded. Thus, the price of a product and the quantity demanded for that product have an inverse relationship, as stated in the law of demand.

    An inverse relationship means that higher prices result in lower quantity demand and lower prices result in higher quantity demand.

    Change in Quantity Demanded

    A change in quantity demanded refers to a change in the specific quantity of a product that buyers are willing and able to buy. This change in quantity demanded is caused by a change in the price.

    Increase in Quantity Demanded

    An increase in quantity demanded is caused by a decrease in the price of the product (and vice versa). A demand curve illustrates the quantity demanded and any price offered on the market. A change in quantity demanded is represented as a movement along a demand curve. The proportion that quantity demanded changes relative to a change in price is known as the elasticity of demand and is related to the slope of the demand curve.

    An Example of Quantity Demanded

    Say, for example, at the price of $5 per hot dog, consumers buy two hot dogs per day; the quantity demanded is two. If vendors decide to increase the price of a hot dog to $6, then consumers only purchase one hot dog per day. On a graph, the quantity demanded moves leftward from two to one when the price rises from $5 to $6. If, however, the price of a hot dog decreases to $4, then customers want to consume three hot dogs: the quantity demanded moves rightward from two to three when the price falls from $5 to $4. 

    By graphing these combinations of price and quantity demanded, we can construct a demand curve connecting the three points.

    Using a standard demand curve, each combination of price and quantity demanded is depicted as a point on the downward sloping line, with the price of hot dogs on the y-axis and the quantity of hot dogs on the x-axis. This means that as price decreases, the quantity demanded increases. Any change or movement to quantity demanded is involved as a movement of the point along the demand curve and not a shift in the demand curve itself. As long as consumers' preferences and other factors don't change, the demand curve effectively remains static.

    Price changes change the quantity demanded; changes in consumer preferences change the demand curve. If, for example, environmentally conscious consumers switch from gas cars to electric cars, the demand curve for traditional cars would inherently shift.

    Price Elasticity of Demand

    The proportion to which the quantity demanded changes with respect to price is called elasticity of demand. A good or service that is highly elastic means the quantity demanded varies widely at different price points.

    Conversely, a good or service that is inelastic is one with a quantity demanded that remains relatively static at varying price points. An example of an inelastic good is insulin. Regardless of price point, those who need insulin demand it at the same amount.

    When percentage change in quantity demanded is equal to changes in price the demand curve is Dash?

    When percentage change in quantity demanded is equal to the percentage change in price, the elasticity of demand is unitary elastic. Was this answer helpful?

    When the percentage change in price is equal to the percentage change in quantity demanded?

    Unitary elasticity means that a given percentage change in price leads to an equal percentage change in quantity demanded or supplied.

    When percentage change in demand is less than percentage change in price demand is set to be?

    Answer and Explanation: 1) When the percentage change in the quantity demanded is less than the percentage change in price, then demand is C. inelastic.

    When the percentage change in quantity demanded is the same as the percentage change in price demand is said to have unitary elasticity?

    the percentage change in quantity demanded is larger than the percentage change in price in absolute value​ (a demand elasticity with an absolute value greater than​ 1). When the percentage change in quantity demanded is the same as the percentage change in​ price, demand is said to have unitary elasticity.
