Is elasticity shared by all individual goods?

No, elasticity is not shared by all individual goods; it varies depending on factors such as the availability of substitutes, necessity versus luxury status, and consumer preferences. For example, essential goods like bread tend to have inelastic demand, meaning consumers will continue to purchase them despite price increases. In contrast, luxury items, like designer handbags, often have more elastic demand, where price changes significantly impact consumer purchasing behavior. Thus, elasticity is specific to each good and its market context.
