How much will it cost if you spend 100 in congratulations?
If you increase spending 1, your income will increase by 0.988. In other words, if you spent 100,000 won for the congratulatory speech, you would have collected 98,800 won before and after. Professor Song Hyeon-jae and Son Hye-rim This is an article published by the professor of Economics at the University of Seoul City at the end of last year. The title of the article is "Analysis of the relationship between the expense of congratulation expenses and the revenues of Korean households using the financial panel."
Professor Song has studied about 3,000 families who have spent 10 years in the past. It is a very rare article that deals with the expenses and revenue of the Congress as an academic subject. In an interview with Joongang Ilbo on June 29, Professor Song Hyeon-jae predicted: "Unless the culture of the congratulatory addresses change significantly, the size will be reduced. The following is a questionnaire.
"I started with personal curiosity. As with any other worker, I was often asked to attend the congratulatory address and I was asking:" What kind of thoughts do Korean pay? "When you receive an invitation to the Wedding, or when you listen to obituaries and go to a funeral home, you will be concerned about future economic benefits. I wondered how it really works. "
How have you analyzed?
"Using data from the financial panel of the Korea Institute of Public Finance from 2007 ~ 2016, I asked about spending on congratulation costs and others. It is reasonable to use life-long data for a precise analysis, but not There is data in Korea for more than one generation. Therefore, the financial panel that accumulated 10 years of data could be an alternative. Among the 3488 total dwellings, there were four groups: those who had the expense in congratulations and congratulations , the two groups that only had an income or expense, and those that did not have income or expenses.
How did the result come about?
"The group (1301 households), who had revenues and expenses, spent 9.55 million in winning for 10 years and received 15.23 million earnings. Although it seems that the income is much higher, it is necessary to have The expenditure pattern of congestion expenses and the inflation rate are counted. The cost coefficient was estimated at 0.988. "
What does that mean?
"If the expenses of the greetings address increase by 10,000 won, it means that the revenue from the greetings address increased by 9880 won, that is, almost 10,000 won. This means that revenue from Any home in case of a greeting gift has almost completely saved the cost of congratulatory memories to date. In economic terms, it is called "full insurance".
"If the underlying asset is 100, the probability that the asset is fully guaranteed, that is, the expected value (guaranteed asset) is 100. In a nutshell, revenue and cost are the same."
Is the expected result?
"I built a hypothesis like this (complete insurance), but I did not expect it to happen. It is a relatively surprising result in terms of social commitment of the congregational culture."
It is true even if we look around.
"I still have no money. This study is the result of the long-term patterns of analysis for thousands of households."
There is an increasing number of young people who are not married or are married later. The community's awareness diminishes considerably compared to the past. Could it be that the culture of torture and poverty will change?
"Finally he will do it. As the marriage changes and the life span is achieved, the time to pay the tribute and the time of the collection can be significantly different. The number of cases in which you can not Collecting your expenses will increase. Finally, the reach of the community you manage can be small. In fact, the reach of offline communities is declining. Even so, "individual patrons" will not change easily. "
So how can one change?
"It will not change for a long time. If you anticipate the future and believe that you will earn less in the future, you will have less spending. If you had the experience of" I have paid your compliments and will not return later ", it will become less expense. This is a reasonable option. The culture that exchanges money will not disappear. Instead, I believe that the scope will be reduced. "
There is a small movement of weddings and funerals that do not advertise increase. In addition, the law of prohibition of illegal recourse (Kim Young Ran law) was applied.
"How big is this? The general congregational culture will have a real impact on the pattern of Congress favors if expectations change."
