price elasticity of food would be inelastic, as there are no substitutes and food is a necessity.
The price elasticity of demand measures how responsive the quantity demanded of a good is to a change in its price. The value illustrates if the good is relatively elastic (PED is greater than 1) or relatively inelastic (PED is less than 1). A good's PED is determined by numerous factors, these include:Number of substitutes: the larger the number of close substitutes for the good then the easier the household can shift to alternative goods if the price increases. Generally, the larger the number of close substitutes, the more elastic the price elasticity of demand.Degree of necessity: If the good is a necessity item then the demand is unlikely to change for a given change in price. This implies that necessity goods have inelastic price elasticities of demand.Price of the good as a proportion of income: It can be argued that goods that account for a large proportion of disposable income tend to be elastic. This is due to consumers being more aware of small changes in price of expensive goods compared to small changes in the price of inexpensive goods.The following example illustrates how to determine the price elasticity of demand for a good. The price elasticity of demand for supermarket own produced strawberry jam is likely to be elastic. This is because there are a very large number of close substitutes (both in jams and other preserves), and the good is not a necessity item. Therefore, consumers can and will easily respond to a change in price.
distinguish between price elasticity of demand and income elasticity of demand
1)price elasticity of demand 2)income elasticity of demand 3)cross elasticity of demand
Unitary elasticity is when the price elasticity of demand is exactly equal to one.

distinguish between price elasticity of demand and income elasticity of demand
Availability of substitutes, whether it is a neceesity or luxury, proportion of the purchaser's budget consumed by that item and permanent or temporary price changes.
1)price elasticity of demand 2)income elasticity of demand 3)cross elasticity of demand
Unitary elasticity is when the price elasticity of demand is exactly equal to one.
Cross price elasticity of demand measures the responsivenss of demand for a product to a change in the price of another good.
In economics , the cross elasticity of demand and cross price elasticity of demand measures the responsiveness of the quantity demand of a good to a change in the price of another good.
role of price elasticity of demand in managerial decisions
The price elasticity refers to the change in demand due to the change in price. The income elasticity of demand on the other hand refers to the change in demand due to the change in income.
Cross price elasticity measures the connection between the price of one product and the demand for another product, so it is used to determine whether products are complements, substitutes, or unrelated. For example, if the price of aluminum foil rises and, as a result, the demand for plastic wrap rises, then the cross price elasticity will be a positive and significant number and will support the assertion that these two products are close substitutes. Companies have even used this to defend against allegations of monopoly power, using the cross price elasticity number to demonstrate that they do not have a monopoly since consumers can easily switch to a good substitute.
there are broadly classified into five types 1. Perfect price elasticity of demand 2. Perfect price in-elasticity of demand 3. Relative price elasticity of demand 4. Relative price in-elasticity of demand 5. Unity price elasticity of demand
