How does the quantity supplied of




















Conversely, a fall in price will increase the quantity demanded. When the price of a gallon of gasoline goes up, for example, people look for ways to reduce their consumption by combining several errands, commuting by carpool or mass transit, or taking weekend or vacation trips closer to home.

Economists call this inverse relationship between price and quantity demanded the law of demand. The law of demand assumes that all other variables that affect demand to be explained in the next module are held constant. An example from the market for gasoline can be shown in the form of a table or a graph. A table that shows the quantity demanded at each price, such as Table 1 , is called a demand schedule. Price in this case is measured in dollars per gallon of gasoline. The quantity demanded is measured in millions of gallons over some time period for example, per day or per year and over some geographic area like a state or a country.

A demand curve shows the relationship between price and quantity demanded on a graph like Figure 1 , with quantity on the horizontal axis and the price per gallon on the vertical axis. Note that this is an exception to the normal rule in mathematics that the independent variable x goes on the horizontal axis and the dependent variable y goes on the vertical.

Economics is not math. The demand schedule shown by Table 1 and the demand curve shown by the graph in Figure 1 are two ways of describing the same relationship between price and quantity demanded. Demand curves will appear somewhat different for each product. They may appear relatively steep or flat, or they may be straight or curved.

Nearly all demand curves share the fundamental similarity that they slope down from left to right. So demand curves embody the law of demand: As the price increases, the quantity demanded decreases, and conversely, as the price decreases, the quantity demanded increases.

In economic terminology, demand is not the same as quantity demanded. When economists talk about demand, they mean the relationship between a range of prices and the quantities demanded at those prices, as illustrated by a demand curve or a demand schedule. When economists talk about quantity demanded, they mean only a certain point on the demand curve, or one quantity on the demand schedule. In short, demand refers to the curve and quantity demanded refers to the specific point on the curve.

When economists talk about supply , they mean the amount of some good or service a producer is willing to supply at each price. Price is what the producer receives for selling one unit of a good or service.

A rise in price almost always leads to an increase in the quantity supplied of that good or service, while a fall in price will decrease the quantity supplied. When the price of gasoline rises, for example, it encourages profit-seeking firms to take several actions: expand exploration for oil reserves; drill for more oil; invest in more pipelines and oil tankers to bring the oil to plants where it can be refined into gasoline; build new oil refineries; purchase additional pipelines and trucks to ship the gasoline to gas stations; and open more gas stations or keep existing gas stations open longer hours.

Economists call this positive relationship between price and quantity supplied—that a higher price leads to a higher quantity supplied and a lower price leads to a lower quantity supplied—the law of supply. The law of supply assumes that all other variables that affect supply to be explained in the next module are held constant.

Still unsure about the different types of supply? See the following Clear It Up feature. In economic terminology, supply is not the same as quantity supplied. When economists refer to supply, they mean the relationship between a range of prices and the quantities supplied at those prices, a relationship that can be illustrated with a supply curve or a supply schedule. When economists refer to quantity supplied, they mean only a certain point on the supply curve, or one quantity on the supply schedule.

In short, supply refers to the curve and quantity supplied refers to the specific point on the curve. Figure 2 illustrates the law of supply, again using the market for gasoline as an example. Like demand, supply can be illustrated using a table or a graph.

A supply schedule is a table, like Table 2 , that shows the quantity supplied at a range of different prices. Again, price is measured in dollars per gallon of gasoline and quantity supplied is measured in millions of gallons. A supply curve is a graphic illustration of the relationship between price, shown on the vertical axis, and quantity, shown on the horizontal axis.

The supply schedule and the supply curve are just two different ways of showing the same information. Notice that the horizontal and vertical axes on the graph for the supply curve are the same as for the demand curve. The shape of supply curves will vary somewhat according to the product: steeper, flatter, straighter, or curved.

Conversely, as the price falls, the quantity supplied decreases. Because the graphs for demand and supply curves both have price on the vertical axis and quantity on the horizontal axis, the demand curve and supply curve for a particular good or service can appear on the same graph.

That said, some goods or services have their quantity supplied dictated or influenced by the government or a government body. In theory, this should work fine as long as the price-setting body has a good read of the actual demand. Unfortunately, price controls can punish suppliers and consumers when they are not set at rates that approximate a market equilibrium.

If a price ceiling is set too low, suppliers are forced to provide a good or service that may not return the cost of production including a normal profit]. This can lead to losses and fewer producers. If a price floor is set too high, particularly for critical goods, consumers are forced to use more income to meet their basic needs. In most cases, suppliers want to charge high prices and sell large amounts of goods to maximize profits. While suppliers can usually control the number of goods available on the market, they do not control the demand for goods at different prices.

As long as market forces are allowed to run freely without regulation or monopolistic control by suppliers, consumers share control of how goods sell at given prices. Consumers want to be able to satisfy their demand for products at the lowest price possible.

If a good is fungible or a luxury, then consumers can curb their buying or seek alternatives. This dynamic tension in a free market ensures that most goods are cleared at competitive prices.

Supply is the entire supply curve, while quantity supplied is the exact figure supplied at a certain price. Supply, broadly, lays out all the different qualities provided at every possible price point. Quantity demanded is the exact amount of a good or service demanded at a given price. More broadly, demand is the ability or willingness of a buyer to pay for the good or service at the offered price point. Demand charts all the amount of demand at each given price.

Example of Quantity Supplied. Key Takeaways The quantity supplied is the amount of a good or service that is made available for sale at a given price point.

Definition: Quantity supplied is the quantity of a commodity that producers are willing to sell at a particular price at a particular point of time. Description: Different quantities can be supplied at different prices at a particular point of time. When all the prices along with quantity supplied are drawn on a graph, the supply curve is formed.

Quantity supplied can change at the same price depending upon factors like recession, changes in the prices of the raw materials, etc. Service tax is a tax levied by the government on service providers on certain service transactions, but is actually borne by the customers. It is categorized under Indirect Tax and came into existence under the Finance Act, Description: In this case, the service provider pays the tax and recovers it from the customer.

Service Tax was earlier levied on a specified list of services, but in th. A nation is a sovereign entity. Any risk arising on chances of a government failing to make debt repayments or not honouring a loan agreement is a sovereign risk. Description: Such practices can be resorted to by a government in times of economic or political uncertainty or even to portray an assertive stance misusing its independence. A government can resort to such practices by easily altering.

A recession is a situation of declining economic activity. Declining economic activity is characterized by falling output and employment levels. Generally, when an economy continues to suffer recession for two or more quarters, it is called depression. Description: The level of productivity in an economy falls significantly during a d.

It is always measured in percentage terms. Description: With the consumption behavior being related, the change in the price of a related good leads to a change in the demand of another good. Related goods are of two kinds, i.
