Graphical representations[ edit ] Although it is normal to regard the quantity demanded and the quantity supplied as functions of the price of the goods, the standard graphical representation, usually attributed to Alfred Marshallhas price on the vertical axis and quantity on the horizontal axis.
Since determinants of supply and demand other than the price of the goods in question are not explicitly represented in the supply-demand diagram, changes in the values of these variables are represented by moving the Essay on price elasticity of demand and demand curves often described as "shifts" in the curves.
By contrast, responses to changes in the price of the good are represented as movements along unchanged supply and demand curves. Supply schedule[ edit ] A supply schedule is a table that shows the relationship between the price of a good and the quantity supplied.
Under the assumption of perfect competitionsupply is determined by marginal cost. That is, firms will produce additional output while the cost of producing an extra unit of output is less than the price they would receive.
A hike in the cost of raw goods would decrease supply, shifting costs up, while a discount would increase supply, shifting costs down and hurting producers as producer surplus decreases. By its very nature, conceptualizing a supply curve requires the firm to be a perfect competitor i.
This is true because each point on the supply curve is the answer to the question "If this firm is faced with this potential price, how much output will it be able to and willing to sell?
Economists distinguish between the supply curve of an individual firm and between the market supply curve. The market supply curve is obtained by summing the quantities supplied by all suppliers at each potential price.
Thus, in the graph of the supply curve, individual firms' supply curves are added horizontally to obtain the market supply curve. Economists also distinguish the short-run market supply curve from the long-run market supply curve. In this context, two things are assumed constant by definition of the short run: In the long run, firms have a chance to adjust their holdings of physical capital, enabling them to better adjust their quantity supplied at any given price.
Furthermore, in the long run potential competitors can enter or exit the industry in response to market conditions. For both of these reasons, long-run market supply curves are generally flatter than their short-run counterparts.
The determinants of supply are: Production costs are the cost of the inputs; primarily labor, capital, energy and materials. Productivity Firms' expectations about future prices Number of suppliers Demand schedule[ edit ] A demand schedule, depicted graphically as the demand curverepresents the amount of some goods that buyers are willing and able to purchase at various prices, assuming all determinants of demand other than the price of the good in question, such as income, tastes and preferences, the price of substitute goodsand the price of complementary goodsremain the same.
Following the law of demandthe demand curve is almost always represented as downward-sloping, meaning that as price decreases, consumers will buy more of the good. The demand schedule is defined as the willingness and ability of a consumer to purchase a given product in a given frame of time.
It is aforementioned that the demand curve is generally downward-sloping, and there may exist rare examples of goods that have upward-sloping demand curves.
Two different hypothetical types of goods with upward-sloping demand curves are Giffen goods an inferior but staple good and Veblen goods goods made more fashionable by a higher price. By its very nature, conceptualizing a demand curve requires that the purchaser be a perfect competitor—that is, that the purchaser has no influence over the market price.
This is true because each point on the demand curve is the answer to the question "If this buyer is faced with this potential price, how much of the product will it purchase? Prices of related goods and services.
Consumers' expectations about future prices and incomes that can be checked.Elasticity of Demand – Essay Sample Elasticity of demand only deals with one good, but Cross-price elasticity deals with two commodities.
Income elasticity deals with income and quantity demanded. Price controls Price ceilings (maximum prices): rationale, consequences and examples. Price ceilings (maximum prices): is a situation where government sets a maximum price, below the equilibrium price to prevent producers from raising the price above it.
Published: Mon, 5 Dec There are generally three types of elasticity of demand, which are price, cross-price and income elasticity of demand.
These three will be explained individually in order in the following paragraphs. Price elasticity of demand is another concept showing a change in the responsiveness of a good or service due to a change in its price.

Price elasticity of demand is a measure of the responsiveness of change in quantity demanded of a good/service to a change in price, ceteris paribus. As the law of demand indicates, when the price of a good/service increases, the demand of it will decrease.
