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与供给的对比。

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

   若热浪摧毁香蕉作物，运抵商店的香蕉减少，价格便会上涨。

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

   当一款新应用让拼车更便宜时，出租车 fares 常为保持竞争力而下调。

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

   卖家紧盯同行定价，迅速调整以避免空座或库存积压。

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

   买家也会响应——价格上涨时，许多人会寻找替代品或观望等待。

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.

   这并非完美机制，但通常无需中央调控即可实现供需平衡。
