"This is economics too!"

When Wang Qingkong sat down, Su Mo concluded. Pen & Fun & Pavilion www.biquge.info

"The first two questions reflect the economics of product design, using the principles of economics to explain the problems that we will not consider in daily life, maybe the students of the business school can probably understand, but the students of other colleges are estimated to be a little difficult, what cost-effectiveness, fixed costs, we don't understand at all, it doesn't matter, we can be simpler, other theories of economics do not understand, but the simplest theory of supply and demand must be understood by everyone here, if there are really people who do not understand, I really want to ask, classmates, how did you get into the university?"

Su Mo's class is always funny and interesting, and whenever this happens, he is a unique god, and his words and deeds firmly control the rhythm of the entire venue.

"Third Question......"

Su Mo deliberately slowed down the speed of speaking, and when he saw that many people in the audience were gearing up to perform, he was relieved, young people are like this, how can they do without a little sharpness?

"Anyone who has been to a bar will know that some bars cost three yuan for a glass of water, but they can provide free melon seeds and peanuts, and the production cost of melon seeds and peanuts is definitely higher than that of water, so what is this all about? Which student wants to come this time? ”

After a short period of thought, the hand in the field was like a mole poking its head out of the ground and raising it upwards with a bang.

"Well, everyone is very active, it seems that they are in the state, but this time I want a non-economics major to answer this question, economics majors, please put down your hands, there will be a chance for you to perform later"

As soon as this restriction came out, seventy or eighty percent of the people who raised their hands fell, and then Su Mo randomly ordered a muscular male classmate: "Which college are you from, this classmate?" ”

"Well, I'm from the School of Physical Education," the male student replied with some embarrassment.

Su Mo looked at his tall body and nodded: "There is a saying that 'limbs are well developed and the mind is simple', I hope you will use your performance to break this lie!" ”

"Hmm!" The male classmate nodded heavily, answered a question, and clenched his fists as if he was on the battlefield.

"I understand it this way, the core product of the bar is alcoholic beverages, melon seeds and peanuts and wine are complementary, the more melon seeds and peanuts a customer eats, the more beer or drinks he orders, since melon seeds and peanuts are relatively cheap, and each alcoholic beverage can bring relatively objective profits, then the practice of providing melon seeds and peanuts for free can be understood."

"But water is different, it is not compatible with alcoholic beverages. The more water customers drink, the less alcoholic beverages they order, and even if the water is relatively cheap, the bar still has to set a high price for it to discourage customers from consuming water. The above is the answer I see from the relationship between supply and demand, Mr. Su, am I right? ”

"Yes, that's right! Please also give a warm round of applause to this student with developed limbs and a more developed mind! ”

So far, everyone's enthusiasm has been mobilized, it turns out that there is really so much economic knowledge in life, and it can be explained like this!

"Next, I want to ask a difficult question, students who study economics, your opportunity has come! The previous question said that bars charge for water, but as we all know, many restaurants offer free refills, so why is that? ”

Hearing this question, many people's first reaction is that this is too simple, providing free refills can attract customers to come and enhance competitiveness, but then I think about it, no, most restaurants have this service, how to talk about what is different and increase competitiveness?

This question is indeed a bit difficult, the more people who can't figure it out think about it, the more confused they feel, and even some teachers and professors frown, not because they don't have a thick foundation and don't have deep knowledge, but because their thinking is a little fixed.

That's why there are so many economics teachers in universities, but so few can become famous economists.

However, one man stood up.

"It's you again, classmate Wang Kongqing, it's good, you can answer this question again, right?"

Su Mo looked at the girl who stood up, who looked like she was wearing glasses but had smart eyes, and smiled.

"We can imagine the initial situation"

Wang Kongqing was radiant at this time, and there was a special beauty, which she had never appeared because she usually had some inferiority complex because of her mediocre appearance.

"All restaurants don't offer free refills, if there is a restaurant that takes the lead in offering this service, then diners who enjoy free refills at that restaurant will feel that they have made a good deal, and as word of mouth spreads, the restaurant will have a large increase in customers than before, although this service will increase the cost, but this part of the cost is quite low, and the benefits due to the increase in customer traffic are enough to offset this part of the cost, or even get a greater benefit"

"The point is, when you see the success of this restaurant, other restaurants will follow suit. As more restaurants do this, the increase in customers at the first restaurant decreases, and when every restaurant offers this service, it's about the same as when they didn't offer it before, and because the margins are so thin, for many restaurants, free refills seem to be a sign of a loss."

"But when we turn a corner, we can think that because of the free refill service, diners are getting more net profit than before in the process of dining, because now they are getting a service that used to cost a few dollars for nothing, and this fact will prompt restaurants to raise the price of meals, and when the dust settles, the price of meals should be roughly enough to cover the cost of free refills, this is my understanding, Mr. Su?"

Many people suddenly realized, yes, restaurants can increase the price of meals to offset the cost of free refills, and because free refills make consumers profitable, they will not be so sensitive to the increase in meal prices, why didn't we think of it!

On this day, many people remembered this girl named Wang Kongqing, and even the media gave her a lot of shots, thinking about going back to write an interview.

"Mr. Wang, you are very right, but another factor that needs to be considered is that a refill cup that is only worth a few cents, such as coffee, may have to be charged more than a dozen yuan in a restaurant, and if you want to drink enough, a person has to refill the cup countless times. If 10 percent of customers order a drink for a free refill, it's almost certain that the restaurant is making a profit. ”

Su Mo first praised, and then added.

(To be continued, more exciting later!) ）

(These two chapters are coded out in the Internet café again, since I bought the computer, I haven't been to the Internet café for a long, long time, and the thinking is still stuck in the era of two or three dollars an hour of Internet access in the Internet café, but now it's about five yuan, alas, other people's updates are making money, I'm taking money, which student can comfort me with the principles of economics?) ）
