How to use these flashcards

Work through these flashcards in short sessions. Try to answer each prompt before flipping the card, then revisit any cards you miss until the explanation feels automatic.

Flashcard 1: How does product differentiation impact market power?

Answer: Increases market power. Unique products reduce substitutability and price sensitivity.

Flashcard 2: What is the relationship between MR and D in monopolistic competition?

Answer: $MR < D$. Downward-sloping demand makes marginal revenue less than price.

Flashcard 3: What is the relationship between average cost and price in long-run equilibrium?

Answer: Price equals average cost. Zero economic profit condition in long-run equilibrium.

Flashcard 4: What is the role of advertising in monopolistic competition?

Answer: To differentiate products. Creates perceived differences to build customer loyalty.

Flashcard 5: What happens to economic profits in the long run in monopolistic competition?

Answer: They become zero. New firms enter until no excess profits remain.

Flashcard 6: What is the profit-maximizing condition for monopolistic competition?

Answer: $MR = MC$. Standard profit-maximizing rule for all market structures.

Flashcard 7: What is excess capacity in monopolistic competition?

Answer: Producing below minimum ATC. Firms don't operate at the efficient scale of production.

Flashcard 8: What is the profit-maximizing condition for monopolistic competition?

Answer: $MR = MC$. Standard profit-maximizing rule for all market structures.

Flashcard 9: How is long-run equilibrium achieved in monopolistic competition?

Answer: Firms enter or exit until zero profit. Free entry and exit drive economic profits to zero.

Flashcard 10: State the formula for total revenue (TR).

Answer: $TR = P \times Q$. Total revenue equals price multiplied by quantity sold.

Flashcard 11: Which curve represents the firm's perceived demand in monopolistic competition?

Answer: The demand curve. Each firm faces its own downward-sloping demand curve.

Flashcard 12: How does entry of new firms affect the demand curve in monopolistic competition?

Answer: It shifts the demand curve left. New entrants reduce each firm's market share and demand.

Flashcard 13: What is the reason for zero economic profit in long run?

Answer: Entry and exit of firms. Market forces eliminate above-normal profits over time.

Flashcard 14: What happens to a firm's profits if it fails to differentiate in monopolistic competition?

Answer: Profits decrease. Similar products reduce competitive advantage and pricing power.

Flashcard 15: What is the typical result of a firm offering a unique product feature?

Answer: Increased market share. Differentiation attracts customers from competitors.

Flashcard 16: What is the impact of new entrants on existing firms' profits?

Answer: Profits decrease. Additional competition reduces demand for existing firms.

Flashcard 17: How does a firm in monopolistic competition decide its output level?

Answer: Where $MR = MC$. Produces where additional revenue equals additional cost.

Flashcard 18: What happens to consumer surplus in monopolistic competition compared to perfect competition?

Answer: It is lower. Inefficiency from pricing above marginal cost reduces surplus.

Flashcard 19: What happens to prices when a monopolistic competitor exits the market?

Answer: Prices may increase. Reduced competition allows remaining firms more pricing power.

Flashcard 20: What does non-price competition involve?

Answer: Advertising and service. Competition through quality, service, and brand building.

Flashcard 21: What is a firm's goal in monopolistic competition?

Answer: Maximize profit. Standard objective for firms in any market structure.

Flashcard 22: Identify a key feature of monopolistic competition.

Answer: Product differentiation. Allows firms to have some pricing power unlike perfect competition.

Flashcard 23: What is the typical shape of a firm's marginal cost curve?

Answer: Upward sloping. Reflects increasing variable costs as output expands.

Flashcard 24: What does non-price competition involve?

Answer: Advertising and service. Competition through quality, service, and brand building.

Flashcard 25: Identify one way monopolistic competition benefits consumers.

Answer: Greater variety of products. Product differentiation creates diverse consumer options.

Flashcard 26: In monopolistic competition, what is the effect of brand loyalty?

Answer: Reduces elasticity of demand. Customer loyalty makes demand less responsive to price.

Flashcard 27: What is the demand curve shape for a firm in monopolistic competition?

Answer: Downward sloping. Product differentiation gives firms some pricing control.

Flashcard 28: What is the role of non-price competition in monopolistic competition?

Answer: To differentiate products. Competition beyond price through quality and features.

Flashcard 29: What is the typical shape of a firm's marginal cost curve?

Answer: Upward sloping. Reflects increasing variable costs as output expands.

Flashcard 30: What happens to a firm's profits if it fails to differentiate in monopolistic competition?

Answer: Profits decrease. Similar products reduce competitive advantage and pricing power.

Flashcard 31: How does a firm in monopolistic competition determine its pricing strategy?

Answer: Based on product differentiation. Unique features allow premium pricing above competitors.

Flashcard 32: How is long-run equilibrium achieved in monopolistic competition?

Answer: Firms enter or exit until zero profit. Free entry and exit drive economic profits to zero.

Flashcard 33: What is the role of advertising in monopolistic competition?

Answer: To differentiate products. Creates perceived differences to build customer loyalty.

Flashcard 34: What happens to prices when a monopolistic competitor exits the market?

Answer: Prices may increase. Reduced competition allows remaining firms more pricing power.

Flashcard 35: Which curve represents the firm's perceived demand in monopolistic competition?

Answer: The demand curve. Each firm faces its own downward-sloping demand curve.

Flashcard 36: How does price compare to marginal cost in monopolistic competition?

Answer: Price is greater than marginal cost. Market power allows pricing above marginal cost.

Flashcard 37: What is the reason for zero economic profit in long run?

Answer: Entry and exit of firms. Market forces eliminate above-normal profits over time.

Flashcard 38: What happens to consumer surplus in monopolistic competition compared to perfect competition?
