From an economic point of view, why do hotel accommodation and air tickets have to increase in price on Friday and Saturday?

HolidayEconomy refers to a systematic economic model in which people use holidays to concentrate on shopping and consumption, so as to promote the development of supply, market and economy. Some people vividly call it: because some people have a rest, some people get a chance to work. Holiday economy belongs to the category of consumer economy.

The change of people's consumption concept. Influenced by traditional morality and years of hard life under "shortage economy", most people in China pay more attention to accumulation than consumption, especially spiritual consumption and the improvement of life quality. In fact, this is suitable for low income levels. Engel's law shows that with the increase of income level, the proportion of low-grade goods and basic consumer goods in total expenditure will decrease, and the proportion of cultural and educational expenditure of high-grade goods will increase greatly. With China entering the period of "relative surplus economy", under the influence of government and media measures, residents' consumption concept has gradually changed. Without this, the "holiday economy" is impossible.
