Q

What four things effect price elasticity of a good?

A

Degree of necessity - necessary products are inelastic as they are essential no matter the price

Habit-formed goods - good such as tobacco are inelastic as people are addicted and feel it is crucial to have the product

Substitutability - products with close alternatives are elastic as customers can get better deals elsewhere

Time - in the short run consumers may not be able to find replacement products making it inelastic but in the longer run it become elastic as alternatives can be found

Q

Name the 3 main factors that influence price elasticity of supply?

A

Spare capacity - as if firms have more space available its elastic whereas if they are working at full capacity then its inelastic

Time - it takes firms time to increase production as they may need to employ new resources so in the short run supply cant change much so supply is inelastic whereas long run supply can increase more becoming elastic

Ease of switching products - if its easy to switch products its elastic but if its difficult is inelastic
