Study Notes

Microeconomics Quiz Answers and Concepts

Profit Maximization (Monopoly): A monopoly maximizes profit where marginal revenue equals marginal cost.
Price Takers (Perfect Competition): Firms in perfect competition are price takers because each firm's output is insignificant to the overall market.
No Price Discrimination Example: A flat fee for all users, regardless of consumption, is not price discrimination.
Monopolistic Competition Long Run: Monopolistically competitive firms earn zero economic profit in the long run.
Market Power and Demand: A firm with market power faces a downward-sloping demand curve.
Natural Monopoly Cause: Natural monopolies exist due to declining average total costs over a wide range of output.
Second-Degree Price Discrimination: Consumers self-select into different pricing tiers in second-degree price discrimination.
Oligopoly Example: Smartphone manufacturing is a good example of an oligopoly.
Price Elasticity of Demand: A -2 price elasticity of demand means a 10% price increase will lead to a 20% decrease in quantity demanded.
Perfect Competition Profit Maximization: In perfect competition, firms maximize profit where price equals marginal cost.
Monopolist Output Decision: A monopolist increases output and lowers price when marginal revenue exceeds marginal cost.
Perfect Competition Long Run Losses: If a perfectly competitive firm loses money in the long run, firms exit, raising market price.
Barriers to Entry: High advertising costs, economies of scale, and exclusive access to resources are typical barriers to entry.
Kinked Demand Curve Model: The kinked demand curve model describes pricing rigidity in oligopolies.
Productive Efficiency: Perfect competition achieves productive efficiency in the long run.
Inelastic Demand and Revenue: If demand is inelastic and the price decreases, total revenue increases.
Monopolistic Competition Feature: Monopolistic competition is defined by differentiated products.
Profit Maximization (Marginal Cost/Revenue): A profit-maximizing firm should reduce output when marginal cost exceeds marginal revenue.
Perfect Competition Profit Maximization Point: A perfectly competitive firm maximizes profit by producing where price equals marginal cost.
Relevance of Game Theory (Market Structure): Game theory is most relevant in oligopolies.
Perfect Price Discrimination: Perfect price discrimination eliminates consumer surplus.
Monopolistic Competition Inefficiency: Monopolistically competitive firms don't achieve productive efficiency as they produce where average total cost isn't minimized.
Marginal Revenue of a Monopolist: A monopolist's marginal revenue is always less than price because the firm must lower price to sell more.
Perfect Competition in the Long Run: In perfect competition, firms earn zero economic profit in the long run, and marginal cost equals price.
Price Leadership in Oligopoly: Price leadership in an oligopoly occurs when the dominant firm sets price and other firms follow.
