These goods are all examples of products that have an inelastic demand. This means that consumers are less sensitive to price changes. In other words, if the price increases by a certain percentage, the quantity decrease will be smaller than the price increase. There are different reasons for consumers to have inelastic demand, though.
- Epipen is a product that injects an anti-allergen drug into a person having an allergic reaction. It can save lives, so consumers will still buy it if they are facing an emergency.
- Salt has an inelastic demand because it is a small part of the consumer budget. Since salt is cheap, it could increase significantly in price, and consumers would still purchase it.
- Gasoline has an inelastic demand because there are no other goods that can be purchased (called a substitute) to fuel most cars.
- Cigarettes have an inelastic demand because the people who purchase them are often addicted to smoking them, so they will still purchase them if they get more expensive.
- Toilet paper has an inelastic demand because it is a small part of the budget when calculating per unit price, but it also does not have many close substitutes.
- Life-saving drugs and surgeries have an inelastic demand because their consumers are often facing death and will still be willing to purchase if the price increases.
