The kinked demand curve depicts (LO3) a) cutthroat competition c) collusive oligopoly b) cartels d) price leadership

The kinked demand curve refers to a model in oligopoly markets where firms are price-takers with rigid prices, as they assume that their rivals will follow them with price cuts but not with price increases. This leads to a "kink" in the demand curve at the current price level, with a more elastic demand curve below the current price and a less elastic demand curve above it.

Now that we understand the kinked demand curve concept, let's examine each option in relation to this concept. a) Cutthroat competition: This refers to a very aggressive market situation where firms are constantly undercutting each other's prices to gain market share. This does not fit the concept of the kinked demand curve, as firms are not price-takers and there is no rigidity in prices. b) Cartels: These are organized groups of firms that work together to control prices, output, or other market factors. While cartels operate in oligopolistic markets and could potentially result in a kinked demand curve, it isn't a direct representation of the concept. c) Collusive oligopoly: A collusive oligopoly consists of firms within an oligopolistic market that coordinate pricing and production decisions, either formally or informally. This market structure is closely related to the kinked demand curve, as firms are often price-takers and may create the kinked demand curve through their coordinated actions. d) Price leadership: This occurs when one firm in an oligopolistic market sets prices and other firms follow them. While this may lead to price rigidity, it doesn't explicitly represent the kinked demand curve concept, as there isn't an assumption that rivals will only follow price decreases but not increases.

Based on our analysis in step 2, we can conclude that option (c) collusive oligopoly best represents the kinked demand curve, as it involves firms within an oligopolistic market coordinating pricing decisions, leading to price rigidity and the kinked demand curve. So, the answer is (c) collusive oligopoly.
