Lecture 10 - Monopolistic Competition Flashcards
Monopolistic competition
market structure where barriers to entry are low and many firms compete by selling similar, but not identical products
Product group
each firm’s output is differentiated in some way
marketing
all of the activities necessary for a firm to sell a product to a consumer
brand management
the actions of a firm intended to maintain the differentiation of its product over time
What is the economic profit in the long run in monopolistic competition?
zero
What are two ways advertising affects demand?
- makes consumers aware of a product, which decreases search costs and increases demand
- It makes demand more inelastic by persuading consumers to buy the product because it is “different”
Promotions are the opposite of
Branding campaigns
Which fare better in the long run? Branding or promotions
promotions
Output Effect
Revenue increase due to increase in output sold because of a price reduction
Price Effect
Revenue decrease due to a decrease in price in order to sell more output
How do you know when the price effect is greater than the output effect due to a cost reduction?
When marginal revenue is negative (crosses the x-axis)
What happens when the output effect is greater than the price effect?
Total revenue increases
What happens when the price effect is greater than the output effect?
Total revenue decreases
The monopolistically competitive firm chooses output such that
MC = MR
How do you show profit at the optimal output level graphically?
height of rectangle is price (demand curve) to ATC and length is Q
How do you find the profit maximizing price in monopolistic competition?
Where the demand curve is above the optimal level of output (MR=MC)
Why do firms in monopolistic competition earn zero economic profit in the long run/
positive economic profits means more firms enter product group, decreasing demand for existing firms until all firms earn zero economic profit
In the long run, what is the price for a monopolistically competitive firm?
price=atc
When is there zero economic profit?
when demand = atc
Is monopolistic competition productively or allocatively efficient?
Neither
?Why is monopolistic competition inefficient
There is excess capacity - firms choose output at less than minimum efficient scale, underutilizing available resources
How can firms push back the onset of the long run?
- innovate to reduce costs relative to competitors and benefit from promotions
- change branding strategies to convince customers that their product is different
True or False: market power permits firm to appropriate all of the consumer surplus
False, firms may only appropriate some
How do monopolists strategize to further appropriate consumer surplus?
Price discrimination
