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. Show
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
Quantity DemandedUnderstanding Quantity DemandedInverse Relationship of Price and DemandThe 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 DemandedA 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 DemandedAn 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. Julie Bang / InvestopediaAn Example of Quantity DemandedSay, 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 DemandThe 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. Is the amount of a good or service consumers are willing and able to buy a various possible prices during a specified time period is?Demand-a schedule or a curve showing the various amounts of a product consumers are willing and able to buy at each of a series of possible prices during a specified period of time. Quantity Demanded-the amount of a good that consumers choose to buy at a particular price.
Is the amount of a good or service that consumers are willing and able to buy at a certain price?Demand is simply the quantity of a good or service that consumers are willing and able to buy at a given price in a given time period. People demand goods and services in an economy to satisfy their wants, such as food, healthcare, clothing, entertainment, shelter, etc.
What is the amount of a product that consumers are willing and able to buy at a given price *?We defined demand as the amount of some product that a consumer is willing and able to purchase at each price. This suggests at least two factors, in addition to price, that affect demand. “Willingness to purchase” suggests a desire to buy, and it depends on what economists call tastes and preferences.
Which term refers to the amount of a good or service?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.
