26
Q

Why may demand curves not slope downward?

A

Speculative demand, goods for which consumers use price as an indicator of quality, Veblen goods.

27
Q

Why does speculative demand cause demand curves to not slope downward?

A

For goods such as stocks, housing etc., as price increases, people may purchase these goods as they predict (speculate) that the good will further increase in price.

28
Q

Why do goods for which consumers use price as an indicator of quality cause demand curves to not slope downward?

A

If there is a situation of asymmetric information, a buyer may choose to purchase a good that has a higher value because they believe it is of higher quality.

29
Q

Why do Veblen goods cause demand curves to not slope downward?

A

Some people wish to consume a good such as a Ferrari as a signal of their wealth. As they cost a lot, people buy them. Companies can use advertising campaigns such as Stella Artois that said it was ‘reassuringly expensive’ to drum up sales as it attempted to become a premium brand.
