Outdated index does not reflect changing eating culture, analysts say
By Park Hyong-ki
A 45-year-old Shin who works for a tech company comes home after work and often watches variety shows featuring celebrities eating out at the best restaurants.

"Every time, I turn on the television and switch channels, all I see is someone or a group going to the best places here or overseas to eat. Or some famous chef visiting a local diner to help another cook," said Shin, who asked to remain anonymous.
"Then, I get guilty pleasure from buying food and eating like them. I try to fight the temptation of overindulging myself."
Such shows are one of reasons driving people to increase their spending on food, analysts say.
And the rising consumer prices of meat and vegetables have further increased their food purchases in proportion to their total spending.

"With such food shows, inflation and the growing number of singles and working couples preferring to buy and eat ready-made premium food, the coefficient seems to have increased," said Yun Chang-hyun, an economist at the University of Seoul.
Ernst Engel, a German statistician, introduced his index in 1857.
His theory was when a household's income grows, the percentage of the income spent on food decreases.
For example, when a household's total spending amounts to $200, and it spent $80 on food, the coefficient would stand at 40 percent.
If that household's income increases, it would not continue to spend 40 percent on food, but less on food, and more on other goods, according to Engel's law.
His index was aimed at measuring the relationship between income and food consumption, and ultimately, the standard of living.

Sung Tae-yoon, an economist at Yonsei University, said, "The increasing prices of daily necessities such as vegetables were the key reason behind the rise in the index. This has led most people to spend much less on other goods."
A series of summer heat waves, for one, have fueled such prices over the years.
Even though prices of gas and electricity have decreased on the back of state measures, those of agricultural products have increased.
Overall consumer prices increased 1.5 percent in 2018, but the prices of vegetables and meat rose nearly 4 percent, according to Statistics Korea. This was far higher than the Bank of Korea's inflation target of 2 percent.
The 19th century statistician's index does not reflect inflation, dining out and the changing eating culture amid economic progress. Eating at restaurants is not included in the calculation. If it is added, the coefficient would be higher at over 20 percent here.
To this end, the analysts say the coefficient is a bit outdated and not an "absolute index" that can measure the overall quality of life and health, especially for advanced economies.
"It would be more practical to use it with another index measuring poverty for underdeveloped economies," Yun said.
