Quiz Iii

This document contains a 15 question quiz about market structures and firm behavior in different competitive environments: 1. The questions cover topics like kinked demand curves in oligopoly, profit maximization for monopolies where marginal revenue equals demand, characteristics of perfect competition like being a price taker and not earning economic profits in the long run, and monopolistic competition featuring differentiated goods. 2. Questions also address monopoly and perfect competition situations involving marginal cost and average total cost curves, as well as identifying industries like monopolistic competition with many firms producing differentiated products. 3. Key characteristics that distinguish market structures are tested, such as few firms and barriers to entry in oligopoly, and perfect price elasticity for demand
