Question

Are the following goods non-rival in consumption? a. slice of pizza b. laptop computer c. public radio d. ice cream cone

Short answer

a. Slice of pizza - Rival b. Laptop computer - Rival c. Public radio - Non-rival d. Ice cream cone - Rival

Step-by-step solution

Consider: Slice of Pizza

When one person consumes a slice of pizza, that slice is no longer available for someone else to eat. Therefore, consumption of a slice of pizza is rival in nature, as two people can't consume the same slice at the same time.

Consider: Laptop Computer

When one person uses a laptop computer, that specific laptop is not available for someone else to use simultaneously. Thus, the consumption of a laptop computer is rival, since multiple people can't use the exact same device at the same time.

Consider: Public Radio

When one person listens to a public radio, it does not prevent or reduce the ability of others to listen and enjoy the same radio program. The same audio signal is transmitted to all listeners, so everyone can consume the content without affecting others. So, public radio is non-rival in consumption since one person's consumption doesn't diminish the availability for others.

Consider: Ice Cream Cone

When one person consumes an ice cream cone, that specific ice cream cone is no longer available for someone else to consume. Therefore, the consumption of an ice cream cone is rival, as it can't be consumed by multiple people at the same time. In summary: a. Slice of pizza - Rival b. Laptop computer - Rival c. Public radio - Non-rival d. Ice cream cone - Rival
