问题如下：
A wireless phone manufacturer introduced a next-generation phone that received a high level of positive publicity. Despite running several high speed production assembly lines, the manufacturer is still falling short in meeting demand for the phone nine months after introduction. Which of the following statements is the most plausible explanation for the demand/supply imbalance?
选项：
A.The phone price is low relative to the equilibrium price.
B.Competitors introduced next-generation phones at a similar price.
C.Consumer incomes grew faster than the manufacturer anticipated.
解释：
A is correct.
The situation described is one of excess demand because, in order for markets to clear at the given level of quantity supplied, the company would need to raise prices.
考点：均衡点
A入选，当市场价格低于均衡价格时候，就会出现供给小于需求的情况。
B不入选，竞争对手如果也以同样价格生产这种产品，那么部分消费者就会去买竞争对手的产品，那么该厂家生产产品供不应求的局面就应该得以缓解。
C不入选，因为它不是最根本的原因。只要提价到均衡价格，不管消费者收入如何增长，需求一定就等于供给，不会存在需求短缺。
以前做過渠道銷售 2017年初 DJI出了個新品 當時公司年產量7000個 但是公司也沒預料到市場需求非常大 批發給代理商的貨一瞬間就賣完了（包括經銷商） 市場就出現了此產品零售價8,000（官價） 二級市場最高15000（炒價） 遠大於零售價的現象，請問要是按照這個題目的邏輯 需求大於供給（ D＞S） 爲何價格P會遠高於均衡價 還是題目的邏輯是 假設D＞S 價格就應該被低估 適合long (相對于均衡價格）
