Market Structures

How would you evaluate levels of competition among airlines?
define the relevant market, then look at individual carriers, parent companies or alliences
measures of competition at or over period of time
number of carriers
individual market share
ASK/ATK, RPK/RTK
Flights, seats, passenger etc
market concentration of 3 biggest players C3
Sum of squares of individual market Share = Herfindahl-Hirschmann Index (HHI)
Herfindahl-Hirschmann Indem (HHI)
sum of the squares of the market shares of each individual firm in the relevant market
HHI= s_1^2+s_n^2 etc.
10,000 represents a monopoly
high HHI could lead to regulatory scrutiny in the event of mergers
HHI gives proportionately greater weight to market share of larger firms
Assessment of mergers in the US
Small Change in Concentration
increase of less than 100 points, unlikely to have adverse competitive effects, no further analysis required
unconcentrated markets (HHI below 1.500)
mergers unlikely to have adverse competitive effects, no further analysis required
moderately concentrated markets (HHI between 1500 and 2500)
Mergers that increase the HHI by more than 100 points: potentially competitive concerns, might result in scrutiny
highly concentrated markets (HHI above 2500)
mergers that increase the HHI by 10 and 200 points: potentially competitive concerns, might result in scrutiny
mergers that increase HHI by more than 200 points: increase market power, companies need to provide evidence that merger is unlikely to increase market power

Characteristics of Perfect Competition
conditions that must be satisfied:
homogeneous identical product
large number of independent buyers and sellers
buyers and sellers have perfect information
easy to enter and exit market
no transaction costs
firms are price takers at the market price
equilibrium price depends on demand and supply
horizontal firm demand vs downward sloping industry curve
firms see P=AR = MR
firms can only influence the quantity they produce
Characteristics of Monopolistic Competition
given lack of influence over price under perfect competition, firms seek to differentiate products where possible
under monopolistic competition, there are still many producers
firms have some ability to set prices even though products are very similar as a result of brand loyalty
branding and advertising are therefore key to differentiate products
demand relatively elastic but firm has some ability to set output and price to maximise profit: MR=MC (P>MR)
large price differential will lead costumers to switch
Characteristics of Monoply
Monopoly occurs when there is a single seller of a particular good in a given market
the firm's demand curve is the market demand curve
the firm is protected by entry barriers
government intervention and regulations
intelectual property
capital investment required
technology
economies of scale
the firm is a price maker, subject to market elasticity
can charge price above MC to maximise profit where MR=MC
supply curve. not relevant for monopolist: output depends on MC
Disadvantages of Monopoly
ability to charge high prices and earn above-normal profits
ability to restrict sales to certain customers
ability to price discriminate
no incentive to develop product
no incentive to improve efficiency and reduce costs
Advantages of Monopoly
economies of scale from large operation
lower competitive risk encourages investment
can spend large amounts on R&D
regulation of public/natural monopolies can ensure customer needs are taken into account

Entry Barriers
marked economies of scale in aircraft prodcution
government intervention
bilateral air service agreements
ownership estrictions
licensing or franchising
use of patents e.g. aircraft and engine technology
access to infrastructure
US: Airline leases terminal
Europe: Slots - Grandfather rights
access to distribution systems, if airlines own GDS
predatory behaviour
price cuts, capacity or frequency increases, schedule mirroring
access to factors of production
how easy is it to earmark land for new airport?
access to capital markets
track record of existing vs new airlines
access to information
route demand and performance data available to incumbents
brand loyalty
requires big new entrant investment in advertising
switching costs
FFP programmes lock people in
exit costs?

Oligopoly
Characteristics of Oligopoly
Oligopoly refers to markets with few, large producers
concentration ratio of largest firms is key to measure competition
significant barriers to entry usually present
non-price competition is high with product differentiation - although not always possible e.g. steel vs car industry
price depends on firm's output and on its competitors
firms are price-makers but high degree of interdependence
firms must think through what competitors would do and how they will respond to its actions
difficult to evaluate and there may be no optimal strategy
typical market structure experienced by aircraft and engine manufacturers as well as airlines and airports
Maximising profit in an oligopoly
highly competitive markets tend towards normal levels of profit in the long run based on the lowest cost producer
however monopolists can extract above normal short and long-run profits if they manage costs and know elasticity
in the case of oligopolies, short and long-run profits can be above or below normal levels
outcome depends on entry barriers and competitive dynamic
P= MC in cases of fierce competition
P>> MC where players cooperate implicitly or explicitly
Cooperation vs Competition
Cooperation novels firms reaching agreements with each other for the purpose of limiting competition
agreements can be explicit (collusion) or implicit, resulting in higher prices to consumers and restricted production
significant risk of collusion to alleviate uncertainty as to how competitors will react to enable profit maximisation
anti-trus regulation therefore generally prohibits collusion
collusion (including cartels) outlawed in many countries
however, implicit understandings often arise in stable industries e.g. where firms know from experience how others will respond
Equilibrium price/output in an oligopoly
in an oligopolistic market, each firm will do the best it can given what its competitors are doing
I.e. each firm takes its competitors into account and assumes they are doing likewise
most oligopolies exhibit periods of price stability and profit interspersed with price-changing activity and price wars
some oligopolies are more competitive than others - e.g airlines
Contestability Theory
if new competitors can readily enter a market (no barriers) then the market is contestable
may drive oligpolists to behave as if there was already real competition i.e. lower prices and profits
if an airline increases price, there comes a point where it will encourage new entry and its demand becomes more elastic
ideally the airline should price just below the point at which a new entry is encouraged (P*)
Contestability of airline markets
positive relationship between fares and market concentration -> prices fall when entry occurs
airline markets arguably not perfectly contestable
contradicts expectation of deregulation that markets would be contestable because of asset mobility (aircraft)
however, the industry has been able to establish many barriers to entry that made true contest ability difficult
FFPs, slots and gate access, hub dominance
notwithstanding the above, the industry has struggled to make profit and many successful LCCs have emerged
Kinked Demand Curve Theory
consider an oligopolist with output Q* at price P*
own price increase will have no response from competitors: they will just gain marketshare
own price decrease will be matched by competitors defend market shares
the combined marginal revenue curve is vertical at Q*
this results in price stability even if costs change
Game Theory
in a non-competitive oligopoly, firm behaviour depends on how it thinks its rivals will react but profits lower than under illegal collusion
if you now this, and so does the other firm, then why does implicit coooperation not occur
Game theory: The best strategy a firm can adopt given each assumption about rival's behaviour
the outcome is not necessarily the collusooine one as each firm may be able to make more money by pursuing an alternative strategy, no matter what the competition does
The Prisoners' Dilemma
two parties commit crime, then retained separately, if one confesses it will have a better penalty than without confessing
two airlines with similar cost base competing on the same route who can set pricing low or high
each airline has dominant strategy to charge low fares
they make more money this way no matter what the other does
airlines may eventually reach an understanding they are better off with both charging high fares
attempts to undercut will lead to retaliation and lower profits owverall
if different cost bases; demand stimulation make implicit collusion unlikely
the prisoner's dilemma is a simple game and price rigidity is a natural outcome of equilibrium
firms seek to avoid mutually destructive price competition
real games are more complex, however, and may not have dominant strategies
whether a game is played once or many times will impact on how easily a collusive outcome can be reached
in the absence of collusion, firms may signal price moves e.g. crease in fuel surcharge (price leadership)
in the airline industry, competitive outcomes often prevail despite an oligopolistic structure at route level
Despite oligopolistic attributes, airlines are often unable to extract monopoly profits
airlines would ideally compete on non-price aspects in a "cosy" oligopoly setting, however
price cuts can be easily matched and marginal cost can be very low: the cost of filling another seat very low
non-price aspects can also be easily matched
FFPs, lounges, IFE, seat pitch etc.
some would argue that airline seats are a commmodity
many passengers seem to value price more than other attributes
airlines face different competitors on each route
networks compete against each other: contestability
at city, airport or O&D level there is more competition than on a route level

Summary
there are four distinct market structures on the continuum form monopoly to perfect competition
monopolists can set prices and earn above-normal profits
under perfect competition, price = marginal cost
the airline industry is essentially oligopolistic but pricing tends to be highly competitive and it can be argued hat the industry is relatively contestable given low profits
implicit cooperation unlikely where LCCs are present
several theories try to explain oligopolistic from behaviour
game theory illustrates well the challenges faced by airlines
