Price Elasticity / 价格弹性

中国消费者带动拉夫劳伦增长，东航优化机票退改签政策 adds an airline-flexibility version through China Eastern Airlines. The source argues that loosening refund/change rules can reduce early-booking hesitation, showing that demand responds not only to the ticket price but also to the expected cost of plans changing.

Price elasticity is the episode’s way to explain why a price change can produce very different demand changes across products. In 155.美貌能当饭吃吗?想赚钱该做点啥?拮据时应避免什么行为?经济学思维有什么用？, elastic products may need lower prices to increase total revenue, while necessities, scarce goods, or monopolized goods may keep demand even at higher prices.

The source uses elasticity to slow moralized price judgment. A high price may reflect cost, craft, scarcity, quality, story, status, or weak competition; a low price may reflect scale, subsidy, lower quality, or a different revenue model. The consumer’s task is to inspect the pricing structure instead of treating price alone as proof of virtue or fraud.

Spirit Airlines and the future of cheap flights adds an airline case. Spirit Airlines reveals high price sensitivity among budget travelers: many customers disliked fees and discomfort but still bought the ticket when the fare was cheap enough, making Stated-Revealed Preference Gap visible.

商业小样46 | 买机票时，为什么总要多交两笔钱？ adds an all-in airfare case. Even when the base ticket looks cheap, a fixed civil aviation development fund and a variable fuel surcharge can raise the checkout price; the episode argues that higher total travel cost can reduce passengers’ willingness to fly and weaken airline revenue despite partial fuel-cost recovery.

Key Claims

  • Demand response to price depends on category, alternatives, urgency, status, and monopoly conditions.
  • Brand premium can be real even when material input cost is low, because Subjective Value includes identity and story.
  • Understanding elasticity helps explain why some discounts are growth strategy and others are signs of weak demand or poor quality.
  • Elasticity connects consumer judgment to business-model judgment.
  • Price-sensitive demand can discipline an entire market if low-fare entrants force incumbents to respond.
  • For airfare, consumers respond to the total payable price, not only the base fare shown before regulated funds or surcharges are added.
  • For airfare flexibility, consumers also respond to expected penalty cost if plans change before departure.
