What is kinked demand curve?

Answer: In an oligopolistic market, the kinked demand curve hypothesis states that the firm faces a demand curve with a kink at the prevailing price level. The curve is more elastic above the kink and less elastic below it. This means that the response to a price increase is less than the response to a price decrease.

Which is an oligopoly?
