Oligopoly 寡頭壟斷

- few dominant sellers supplying most of the output => 只有幾個主要的供應者
- many buyers in the market => 差唔多每個家庭都要la
- sellers sell similar but differentiated (有分別) product =>都提供上網服務, 但有快有慢, 有d 有增值服務, 例: 寬頻電話
- there's restriction (限制) of entry of new firms into the market because of huge (大量) capital (資金), technological (技術) and licensing (牌照) requirement (要求) => 係啦
- buyers and sellers cannot get the market information easily => 佢d 唔要好清楚提供價錢, 有d 仲係海鮮價! 人人唔同, 街邊promote 同直接問佢唔同
- dominant seller are interdependent sine they are selling similar goods => 一間減價或者送野, 其他0個d 可能會跟風
