Answer:

Positive

Killed regardless

Explanation:

A market for cats would have had a <u>positive</u> externality because the cats <u>killed rats regardless.</u>

Rats are considered to be found everywhere, from roadsides to kitchens in the households. Since rats in reality were the primary cause of spreading the plague known as the The Black Death, people would be positively influenced to get more cats because they are the natural predators of rats.

The more the cats, the less would be the rats and therefore less possibility of the plague getting spread.

Answer:

A market for cats would have had a positive externality.

Because the cats would kill the rats on sight since that is their natural behavior.

However, it is interesting to mention, that the cat's killing has been more of a "mythic" aspect of this story, since it fails to take into account that since the black death was caused by the<em> yersinia pestis</em> bacteria, cats could have been also infected, and since their interactions with humans are greater than rats or fleas, the real outcome could have been totally unexpected.
