Ringo loves playing rock and roll music at high volume. Luciano loves opera and hates rock and roll. Unfortunately, they are next-door neighbors in an apartment building with paper-thin wall.

What is the externality here?

Thank you for using the Jiskha Homework Help forum. Do you mean the "noise pollution?" Why not suggest that both neighbors get earphones or that the neighbor being annoyed get ear plugs?

I do not understand your response.

The question was regarding externalities.

I understand the noise is the externality. What I am not sure about if both parties causing the externality, since once likes rock and roll and the other opera.

Yes, BOTH parties are contributing to the problem. My response included a possible solution because BOTH parties are undoubtedly disturbing other tenants.

The externality in this scenario is the unintended consequence or side effect of Ringo playing rock and roll music at high volume. Specifically, it affects Luciano who dislikes rock and roll and prefers opera.

To understand the externality in this situation, it's important to acknowledge that the paper-thin walls of the apartment building allow sound to easily transmit from one unit to another. When Ringo plays rock and roll music at high volume, the sound waves pass through the walls and intrude into Luciano's living space. This unwanted noise creates a negative externality for Luciano because it disrupts his peace and enjoyment of his preferred opera music.

In summary, the externality in this scenario is the negative impact of the loud rock and roll music on Luciano's well-being and enjoyment of his living environment.
