Generally speaking, the advertising elasticity coefficient of luxury goods is high, such as jewelry, luxury cars, high-end houses and high-end cosmetics.

Mainly because these are not necessities of life, you can buy them or not.

However, it should be noted that economic analysis is often based on ideal models, which are generally only effective for overall statistics or probability statistics, but not necessarily for personal preference analysis.

For example, someone is a person with high brand loyalty. Take cosmetics as an example. If the price of Dior rises from 1000 to 1 100, it probably has no effect on personal needs. At this time, this person is not sensitive to the price.

In addition, it should be noted that any economic model is based on the assumption that this person is a rational person, that is, it can objectively analyze the advantages and disadvantages, but for individuals, the reality is often not the case. For example, a middle-aged woman with a wealth of one billion has a hobby of collecting jewelry. At this time, even if the price rises, she may not respond to the price because of her personal preferences and crazy hobbies.

It can be seen that many preconditions are set when the model of price elasticity is obtained, such as rational person and neutral risk preference.

Of course, using this model to explain the overall phenomenon of society can indeed draw this conclusion.
