Why Prices Change Without Anyone ‘Deciding’

课文

1. No one sits in a room and sets the price of bananas or train tickets.

   没人坐在房间里决定香蕉或火车票的价格。

2. Instead, prices rise or fall based on how many people want something versus how much is available.

   价格涨跌取决于需求人数与供应量之间的对比。

3. If a heatwave ruins banana crops, fewer bananas reach stores, so prices climb.

   如果热浪摧毁了香蕉作物，运到商店的香蕉就会减少，价格随之上涨。

4. When a new app makes ride-sharing cheaper, taxi fares often drop to stay competitive.

   当一款新应用让网约车更便宜时，出租车费往往也会下调以保持竞争力。

5. Sellers watch what others charge and adjust quickly to avoid empty seats or unsold stock.

   卖家会关注同行定价，并迅速调整，以免座位空置或货物积压。

6. Buyers also respond—when prices go up, many look for alternatives or wait.

   买家也会做出反应——价格上涨时，许多人会寻找替代品或选择观望。

7. This constant push-and-pull between buyers and sellers keeps markets moving.

   买卖双方持续的博弈推动市场运转。

8. It’s not perfect, but it usually balances supply and demand without central control.

   这并不完美，但通常能在无需中央调控的情况下实现供需平衡。
