折弯的需求曲线是垄断厂商面对的在现行的价格下有一个折点的需求曲线,需求在价格上升时要比价格下降时更富有弹性。
The correct conclusion should be this:in the same demand curve, there can be different elasticity to different points, and the price elasticity can be one in the middl.
要不是那些完全垂直或水平的线性需求曲线对点他们该范围从无弹性,弹性和是弹性的单位的一个点。
Linear demand curves, except for those that are perfectly vertical or horizontal, have points on them that range from elastic to inelastic and one piont that is unit elastic.
