Holes in pants used to be a symbol of poverty, but now they have become a sign of fashion. This change comes from the fans' pursuit of stars. Stars are important figures active in film, television, music circles and media. They are like shining stars, appearing even more brilliant under the flattery of numerous fans. There is a story about a star. One day, a certain star was invited to perform on a show, but due to special reasons, he was late. When the host announced his appearance, he hurriedly discovered that there was a big hole in his pants. But with no time to think much about it, he still confidently went on stage. After finishing a song, he completely forgot about the condition of his clothes, focusing instead on interacting with the audience, which often led to enthusiastic applause from the crowd below. In the end, what he didn't expect was that the performance was very successful, and even more unexpectedly, the hole in his clothes became a new favorite among fans. Some obsessed viewers even cut holes in their favorite clothes to imitate his style. Clever merchants seized this favorable business opportunity and quickly launched clothing with "holes" known as "beggar wear". Thus, a storm of beggar wear swept through, with people continuously purchasing these clothes, mostly young people. The star did not expect that one unintentional mistake could cause such a significant market fluctuation, and the fans also did not expect or possibly know that this kind of consumer trend originated from an unexpected oversight by their idol. From this, we can also understand the special intentions behind merchants paying high prices to invite stars to endorse their products. "Stars" have become bridges connecting consumers, a link between them, and a "treasure" for merchants to promote sales. From an economic perspective, these merchants are actually utilizing the "demonstration effect". Demonstration effect refers to the phenomenon of learning from others. It is actually rooted in animal instincts (including higher animals like humans and ordinary animals). For example, monkeys like to eat peaches, but they never wash them. People found a young monkey and taught it to wash the peach before eating. After some time, when this young monkey was put back into the group, it would wash the peach before eating it. However, the other monkeys not only did not learn from its method, but also rejected it. Then, people found the monkey king and taught it to wash the peach before eating. After putting the monkey king back into the group, the situation changed: all the monkeys began to imitate it, and washing peaches before eating became a fashion trend in the monkey world. The demonstration effect in humans is rooted in this animal instinct and gradually evolves under the influence of social factors. In a market economy environment, the demonstration effect is beneficial to promoting economic development. Even in ancient times, examples of the demonstration effect can be found. During the Spring and Autumn period, King Chu liked slender women, so many beauties in the palace competed to diet in order to win the king's favor, striving to be the slimmest palace maid. The result was that they all became emaciated and frail. This ancient fable of "King Chu's preference for slender waists," though clearly satirical, is from the perspective of modern economics, the prototype and origin of the "demonstration effect." King Chu, as the ruler of the country, naturally caused changes in the entire society's consumption trends with his preferences, and the driving force behind these changes came from the influence of the "demonstration effect." High heels originally came from the era of French King Louis XIV. At that time, because of his short stature, Louis XIV could not fully display his noble demeanor in front of his subjects, so he ordered his subordinates to make him a pair of high heels. Afterwards, both male and female French nobles followed suit, leading to their prevalence up to today. In real society, such demonstration effects are everywhere. Fashion consumption is endless. Without "King Chu's preference for slender waists," there would be no weight loss products; without the accidental "gain" of stars, there would be no beggar wear. Therefore, the "demonstration effect" can rightfully be called an "invisible hand" promoting economic development behind the consumer market.
