李昌平：大蒜暴涨与香蕉暴跌

Some regulations to ensure the market is competitive are helpful to ensuring orderly market and to protecting consumers' interests and farmers' interests, the government should not over-regulate and interfere market operations too much.
Market speculation and arbitrage is not necessarily a bad thing. It has its positive effects.
There is a tendance in China that people, especially officials, like to regulate or control market activities that can often lead to inefficiency and losses. Some people just have a control mentality: whenever there is a problem or a perceived one, they want to control things.

很不错，顶一下

北京、上海等大城市可能不会那么明显，但一些中小城市感觉明显，去年普遍在1.8元一斤，今年都是1.2元一斤，摊贩和超市价格几乎相同。

很有道理，顶下

非常好,值得深思

我也觉得楼主没有真正弄明白价格弹性这个概念。

大蒜贵是真贵，现在还4块多一斤呢
香蕉怎么没觉得有便宜呢，但是好吃
不管分析的对不对，能去分析找出一些问题就值得支持

这时就需要国家来进行宏观调控了

弹性的理解好象不对
另外还有大蒜治疗甲流的留言
这也是重要因素
如果说现在有人说香蕉能治疗甲流
涨价指日可待
哈哈

完全是游资炒作造成的结果，
