Q

What are the two steps in identifying competitors in geographical areas?

A

Step 1: locate the catchment area (where the customers come from)

Step 2: find out where the residents of the catchment area shop

With some products like books and drugs being sold over the internet identifying geographic competition becomes more
difficult

Q

What is the intensity of price competition for the 4 classes of market structure?

A
  1. Perfect competition: fierce
  2. Monopolistic competiton: depends on the degree of product differentiation
  3. Oligopoly: depends on inter-firm rivalry
  4. Monopoly: light unless there is threat to entry

Q

Characteristics of perfect competition?

A
  • Many sellers who sell a homogenous good
  • Many well informed buyers
  • Consumers can costlessly shop around
  • Sellers can enter and exit costlessly
  • Each firm faces infinitely elastic demand
  • With perfect competition economic profits go to zero (zero profit condition)
  • When profits are maximized percentage contribution margin
    PCM = 1/η = 0 (η is the elasticity of demand & = infinity)

Q

What might small players do in perfect competition market?

A
  • Small players will be tempted to cheat and small cheaters may go
    undetected
21
Q

Perfect competiton: What are three sources of increased revenue when price is lowered?

A
  • customers buy more
  • New customers buy
  • Customers switch from the competitors
22
Q

What does “homogeneous products and excess capacity” imply in perfect competition?

A
  • Products are indistinguishable between firms, and
  • excess capacity means more supply is available than the demand at current prices, often leading to lower prices
23
Q

Why might a firm price below average cost in perfect competition?

A

When firms operate below their full capacity:

  • they can afford to lower prices temporarily below their average total cost
  • To cover only variable costs when operating below full capacity

Only if they are operating below full capacity – otherwise they are not able to satisfy the increased demand by the lower prices

24
Q

What happens when there is industry-wide excess capacity? (Perfect competition)

A

Prices may fall below average costs,

  • leading some firms to exit the market if they continuously incur losses
  • if exit is not an option, excess capacity and losses will persist for a while
25
Q

What are the characteristics of a monopoly? (Competion, demand curve, price setting)

A
  • A monopolist faces little or no competition in the output market.
  • If some fringe firms exist, their decisions do not materially affect the monopolist’s profits.
  • A monopolist faces a downward sloping demand curve (can set prices with little regard to how other firms will respond).
  • The monopolist sets the price so that marginal revenue equals marginal costs.
  • Thus the monopolist’s price is above the marginal costs and the output is below the competitive level
26
Q

How might a monopolist succeed and benefit consumers?

A
  • A monopolist often becomes dominant by producing more efficiently or better meeting consumer needs than competitors,
  • potentially making consumers net beneficiaries as they receive superior products or services
27
Q

Why are monopoly more innovative than in perfect competition and what’s the impact on consumers?

A

Monopolists are likely more innovative than firms in perfect competition because

  • they can retain a significant portion of the profits from their innovations
  • This innovation benefits consumers,
  • who might suffer in the long run if these profits are excessively restricted, potentially discouraging further innovation.
28
Q

What are the 2 imporant features important to understand pricing in monopolistic competition ?

A

Monopolistic competition is marked by

  • many sellers who
  • they believe that their actions will not materially affect their competitors
29
Q

How do consumers choose products in monopolistic competition and what is the slope of the demand curve?

A
  • Each firm offers a differentiated product, leading consumers to choose based on more than just price (on the basis of other factors)
  • This differentiation results in each firm having a downward-sloping demand curve unlike the flat demand curve in perfect competition, allowing some pricing power.
30
Q

What is vertical and horizontal differentiation?

A
  • Vertically differentiated products unambiguously differ in quality
  • Horizontally differentiated products vary in certain product characteristics to appeal to different consumer groups

An important source of horizontal differentiation is geographical
location

31
Q

What is the situation if you have 2 grocery stores that are located at different locations: On which bases do consumers choose the stores? And what is it?

A
  • Consumers choose the store based on “transportation costs”
  • Transportation costs prevent switching for small differences in price
32
Q

What does transportation cost do? (horizontal differentiation)

A

Transportation costs prevent switching for small differences in price

33
Q

What is idiosyncartic preferences, also in context of horizontal differentiation?

A

=refer to the unique, individual tastes and preferences that vary widely from person to person

–>Horizontal differentiation is possible with idiosyncratic preferences

34
Q

What are important sources for idiosyncratic preferences?

A

–>Location and Taste are important sources of idiosyncratic preferences

–>Horizontal differentiation is possible with idiosyncratic preferences

35
Q

On what does the degree of horizontal differentiation depend upon? and what is it?

A

depends on the magnitude of consumers’ search costs

Search costs: costs of finding information about alternatives

36
Q

What do low cost sellers try to do ? (monopolistic competition)

A
  • Low cost sellers try to lower the search costs to boost their market shares (example: advertising)
37
Q

What happens when there is low search costs? (Effect on Differentiation, prices)

Example market with high search cost?

A
  • Low search costs reduce horizontal differentiation leading to lower prices and lower profits to all firms
  • Market with high search costs: physiciations have high search costs
38
Q

At which level is pricing typically set in monopolistic competition?

A

since each firm faces a downward-sloping demand curve,

  • the price will be set above marginal costs
  • allowing for potential economic profits if price also exceeds average costs
39
Q

Monopolistic competition: How cann a firm earn economic profit, if the price is above marginal costs?

A

if price also exceeds average costs

–>it allows firms to earn economic profit

40
Q

What effect does economic profit have on market entry in monopolistic competition?

A

Economic profits attract new entrants into the market,

–>continuing until economic profits for existing firms are eroded to zero

41
Q

How does new entry affect incumbents in a market characterized by monopolistic competition?

A
  • New entrants decrease market share for incumbents,
  • reducing their revenue and economic profit, regardless of whether or not entry affects prices directly

—>if highly differentiated products: than entry does not lower prices

42
Q

Monopolistic competition: When does the entry of new firms not lower prices?

A

if the products are highly differentiated

43
Q

Under which circumstances is the economic profit erosion aquicker in monopolistic competition with market entry?

A

Generally: the drop in revenue caused by entry will reduce the economic profit:

If there is price competiton -> less differentiated products, the erosion will be quicker

44
Q

How does market exit affect remaining firms in monopolistic competition?

A
  • Exit by some firms can help restore profitability for the remaining firms
45
Q

How does customer loyalty influence pricing and market entry in monopolistic competition?

A
  • Customer loyalty allows prices to exceed marginal costs, and
  • this encourages market entry
46
Q

When is entry considered excessive in monopolistic competition?

A

Entry is considered excessive:
- when it leads to increased fixed costs
- without a corresponding reduction in prices

47
Q

When is the entry in monopolisti markets not excessive?

A

If entry increases the variety of products that is valued by customers

48
Q

What is the difference between the demand curves of monopolistic competition and perfect competition

A
  • This differentiation results in each firm having a downward-sloping demand curve unlike the flat demand curve in perfect competition, allowing some pricing power.
