Q

Criteria for perfect competition

A

Halfpppp
Homogenous products- identical- perfect substitutes, foriegn exchange market
All firms access factor of production
Large no of buyers and sellers
Free costless entry into and exit from market
Perfectly elastic demand curve (horizontal)
Price takers- firms cannot dictate market price

Q

Sr to lr for perfect competition

A

In lr- abnormal profit encourages entry for new firms- signallying mechanism
Decrease price- lras
Lr- normal profit produced ar+ac
No further incentives0 long run equilibrium

Q

Examples perfect competition

A

-foreign exchange- homogenous, wide range of buyers and sellers as many firms, perfect.good info about relative prices, easy to compare prices

-agricultural markets- many farmers selling identical products, many buyers available, market easy to compare prices, perfect info

-internet-price comparison websits
-insurance

Q

Factors for monopolistic comp

A

Large no firms in market
No barriers to entry or exit
Each firm downward sloping demand- differentiated- goods produced partial but not perfect substitutes
Product differentaition means each firm possesses a degree of monopoy power over its product
If brand increases price, doesnt loose all competition as brand loyalty
Industry conc is low- everyone low market share
Non price differnetiation occurs

Q

Sr to lr monopolistic

A

Market structure of monopolistic comp is defined as having low barriers to entry and exit, many buyers and sellers and product differentaiation
Outcome in sr is that firms can earn abnormal profit, this outcome is noty productive or allocative efficnet
Existance sr abnormal profit is attractive to new firms
New firms enter industry as barriers to entry are low
Individ demand curve or av rev curve for incumbent (existing firms in market) shift to left as market shares are reduced
Incumbent firms av rev are cont shift left until reaches a tangent with av cost curve, normal profits covered
Lr, normal profit, not productive or allocative efficient

Q

Advertising monopolistic competition

A

Informal advertising- increases comp- providing consumers and producers with useful info abut g&s available to buy
Persuasive adv- decreases comp- customer become ‘captive consumer’ unwilling buy cheaper subs- may believe product is ‘must have’- pin self worth or perception of others
Saturation advertising- prevent small firms enter market as cant afford adverstising

Q

Explanation price changes on oligopoly

A

Theory starts with assumption that firms are settled on p1,q1
If firm settled on one price, may be little point in changing
Even if costs change often see price regitity, stability in oligoply- sticky prices (seen as mc increase in gap but price not changing between mc1 and mc2
Increased imporatnce attached non price comp

69
Q

Monopolist and allocative inefficiency

A

Main case against monoply is that it maies higher profits at expense of a loss of allocative efficiency
May increase price to cover costs- meaning consuer needs and wants are not being satisficied as product is being under consumerd- case loss of consumer suprlus and will dispoprtionately effect lower income

70
Q

X inefficieny

A

Occurs ween a firm doesnt produce at lowest possible ac
May be due to lazy employees or lack real competion meaning monopolist less of an incentive to invest in new ideas or consider consumer welfare
Any pojnt above ac

71
Q

Rev max more reailstic business objective than profit max for many businesses

A

Loa- depends on strictire and size of firm- to a degree
Trad econ- firms seek to maximise make best possible from available options

Rev max
Profit max
Non profit max

72
Q

Rev max more realistic than profit max- rev max

A

Seek max ref(sales -price) mr=0
Eg divorce of ownership pricniple agent problem
Manager as nonus with rev sales- baumol investigated this
Rectify by profit related bonuses
Try to gain market share0 aldi

73
Q

Profit max- rev max more profit max

A

Seek max profit- total revenue-total cost_ mc=mr
Trad econ most likely
Greater wages/dividens
Retained profit source cheap finances- investment avoids interest rates
Apple market leader can set price- innovation schumpter creative disruption, ipod touch screen, easy to download

74
Q

Not profit max- rev max more than profit max

A

Principle agent problem- shareholders not control- investment
Bounded rationality- large complex firms may be unable to access all finances, aware at margins- but more able for small firms

75
Q

Non colusive oligopoly

A

In a comp oligopoly
Firms act indepentantly dont form agreements with each other

76
Q

Cartel

Sometiems there is also an agreemnt to restrict output and deter entry of new firms
Opec

77
Q

Covert collusion

A

Collusion takes place in secret
Price coluson rigging markets

78
Q

Tacit collusion

A

Understanding without an explicit agreement between firms

79
Q

Overt collusion

A

Full public knoweldge

80
Q

Imperfect comp markets

A

Firm lack accurate info
As outputs signif differ from those currently being rpoduced
Demand curve/ar is not actual- estimate

81
Q

Aims of business collusion

A

Realise their mutual interdependance and act together- main aim max joint profts
Collusion dereased cost comp- eg expensive marketing wage
Reuces uncertainty
Increased profuts increases producer surplus/shareholder value
Enable inefficient firms to stay in business whihle other mroe efficient enjoy abnormal profit

82
Q

Legal colluson

A

Eu comp authorities- practise not prohibited if they contribute to production .distribution of goods or to promote the productiion/distrubtion of goods or to promote improvement of technological process in a market
Development of improved industry stard of production and safety which benefit the consumer- joint industry standarrds for mobile phone chargers in europe
Info sharing designed to give better info for consumer
Research twin bventires- aid innovaion- pharma and covid
Eg citroen, peugot toyota allowed to collude or produce of these cars to decrease productionc osts and benefit from econ of scales - car essentially the same

83
Q

Price fixing

A

[1 (above market price ) becomes cartel price
Makes supernormal profit- but may oversupplyu produce excess output to achieve higher profits- oversupply themselves across cartel

84
Q

Price fixing/collusion easier when

A

Industry regulators are wekk
Penalties for coluson are low relative to potential gain
Participating firms have higher percentage total shares- control market supply
Firms can communicate well and trust each other- have similar strategic observations
Industry products are standardised and output is easily measurable- eg oil
Brands oversupply so that consumers wil not switch demand when cartel raises price

85
Q

Wht do so many cartels break down

A

Decrease market demand in recessoin
Overproduction by some mm=embers
Exposuresure to conmpetitive checks- whistleblowing from former employee or former cartel members
Entry of non cartel firms to indusrty

86
Q

Penalties for cartels in uk

A

Found n breach of comp law fines up to 10% worldwide turnover
Those convicted can get up to 3y improsnment or even up to 15y

87
Q

Costs of collusive behavour

A

Damages consumer welfare- higher prices, loss consumer surpluys, loss allocatiev efficiency , hits lower income families/regressive impact
Absesnse of competition hits efficiency- x ineffeicny leads to higher unit costs, less incentive to innovate/loss of dynamic efficiencies, output quotas penalised firms who want to expand
Reinforce cartel- hard new businesses to enter

88
Q

Potential benefits from collusion

A

General industry standards can bring social beefits- pharma, car safety research
Fairer prices for producer coop in lower and middle income developing componies- decrease rates with extra income generated
Profits have value- how used- capital investment, higher wages for employwrs, randd leading to dnamic effciency

89

100
Q

Local monopoly

A

Rural pub or shop in village

101
Q

Key featres of monopoly

A

Price setting market powwer- can set price ofr q but not both
Downward sloping mrar curves
Potential use of price discrimination
Barriers to entry exist- maintain supernormal (monopoly) profits in lr
Imperfect info is assumed
Profit max objective is assumed

102
Q

Monopoly diagram

A

Mr and are downward sloping
Ac below mc
Supernormal profit and welfare loss

103
Q

Econ case agianst monopoly

A

Prices higher than under comp conditions loss of allocative efficiency (p.mc)
Regressive effect on lower income hohsuehodls
Absense of genuine market comp may lead to productive inefficinecy- x inefficiency wastage produced and advertising spending, higehr pricces limit final output in a amrket and lead to fewer econ of scale being exploited
Less incentive to innovate- less dynamic efficieny
Monopoly may get too big- disecon of scale
Prevents new firsm entering
May use price discrimination- increasing producer surplus as expense of consumer surplus

104
Q

Econ benefits of monopoly

A

Monopolies can reinvent supernormal profits into risky business investments- pharma, medical firms high risk but big
Monopolies generlaly large enough to compete with global companies
Spillover efect for wider market and eocn- reinvest to make more effciicent
Take advantage of econ of scale, which smaller companies may not be able to achieve
Decrease av cost for firms allow lower prices for consumers

105
Q

Natural monopoly

A

V high fixed costs involved supply gands, lrac may fall continuously as output increases lr
Eg water company
Occur when high sunk costs- set up pipelines, build water purification facilities
As q increase cost decrease
Sunk costs act as a barrier to entry as diff for firms to raise finacial capital, fund a proect- little output

106
Q

Legal barriers

A

Inhibit knoweldge other firms may have surrounding production or their capacity for production
Eg copyright- intellectual property, patent
Pharma obtain patent during development if grow only firm with patent to produce that drg

107
Q

Control natural resources

A

Barrier to entry
Precuis metals and oil deposits
De beers controls vast majority diamonds- allow control output

Low barriers to exit
Low product loyalty, not to one brand so can jump

109
Q

Baumol on contestable markets

A

Monopoly is defined by the potential ease or diff with which new firms may enter the arket
Industry conc (conc ratio) not a problem provided absence of barriers to entry and exit - creates the potential for new firms to enetr the makret
Existance of supernormal profits to act as a triggeer for new firms to enter the market
Assuming existing firms wish to prevent new entreants0 set limit pricing and prodduce at productive efficient (lowest on ac

110
Q

Highly contestable markets

A

P.ac
High profit

111
Q

Possible lt equlibrium for previously contestable markets

A

Ac=ar
Normal profit made
Retain sufficiently to keep factor inputs to present use- limit pricing

112
Q

How monopolies create barriers to entry

A

Reduce profit levels below sr profit- normal profit limit rpicing
Constryct artificial barrier-s high advertising expense, predatory pricing
Hit and run behavoir- existing firms supernormal prifits and set price above entry limiit level, new entry will be prevented as long as there is a time lag ebtween entry and reactionary strategies from existing firms
Sgare of suypuernormal profits in intervening periof- new entrant can leave the market at leittle cost- no sunk costs in contestable markets

113
Q

Problem with sunk costs

A

Cannot be recovered after- ie advertising
Act as barrier

114
Q

Example contestable markets

A

Banking- increasing technology,peer to peer funding circles

115
Q

Policies to increaase contestability

A

Removal of licences for transport, tv radio
Removal of controls over ownership- privatisation
Encourage growth of small firms wvia laosn sgrants subsidies
Strategic laws, prosecuting offences, impose larger fines ofn firms
Competition tendering- bid for contracts

116
Q

Eval on contestable markets

A

Threat of new comp is often a powerful influence on behavoir of established firm
Highly contestable market willl resembel perfect comp- regardless no firms-since firms still behave as if inetsne comp
In reality usually sunk costs as it requires advertising to break into any market
May be asysmetrical info as incumbernt firms knwo more about karket and this is barrier to entry

117
Q

Price leadership

Price regulation
Profit regulation
Quality standards
Performance targets

120
Q

Gov intervention for monopolies- price regulation

A

Set price control to force monopolies to choose a price below profit max price- rpi-x (x represents expected efficiency of firm)
Better system is rpi-x+k (k being level of investment)- used in water industry and has allowed investment of 130 bn
Gives incentives for firms to be as efficient as possible in order to increase profits- helps to prevent excessive prices
Diff to knwo whre set x- rapid improvement in technolgy and because any info on what the efficinecy gains will be have to come from firm- asymetric info

121
Q

Gov intervention for monopoles - profit regulation

A

Usa- rate of return regulation is used where prices aresety to allow coversion of operating costs and to earn a fair rate of return on capital invested- based on typical rates of rturn in comp markt
Aims to encourage investment andprevent firms from setting higherrpices gives firms incentive to employ more capital in order to increase profits
But since a reduction in costs will not imporve the firms since there is littel incenctive to be efficiennt- regulators need knwodleg of the indsurty and so will suffer from asymmetric info

122
Q

Gov intervention for monopolies- quality standards

A

Can observe quality of gand s
Gas and electricity amrets regulators ensure eldeerly treated fairly esp in colder months
Post office has deliveries on daily basis to all areas
Electricity generators forced to have enough capacity to prevent balckouts
Require political will to ensure upheld

123
Q

Gov intervention for monopolies- performance targets

A

Regulators can introduce yardstick comp- punctuality targets for train operating companies based on eurpe
Split a service into regional sectors to compare- water indsutry
Targets on price, quality, consumer choice and ocsts of production, imrpoves service and gains for consumer
Firms will resist the introduction of targets- required political wil and understanding- frims will attempt to find ways to meet targets when actually imposes it- change train tiems so not technically running late

124
Q

A

Occurs when regulatory agencies act in the interest of regulated firms rather on behald of consumers supposeed to protect
Ie director general of oflot agnecy regulates national lottery was caught accepting free air tickets and other ‘sweetners’ from one of lottery companies supposed to regulate
Also may occur without regulator ehaving irresponsibly - asymmetric info , regulator may rely on regulated industries. For info so may be lied to

131

Revenue raising- for state short term cash
Reducing public spending and gogv borrowing requirement- on lossmaking indsutries such as rover group on subsidies
Promotion of comp- break up of monopolies, with regulating agnecies to ensure
Promotioon of efficiency- profit incentive
Popular capitalism- extended share ownership to employees and other individ who had not prevuously owned shares

132
Q

Case against privatisation

A

Monopoly abuse- transfers socially owend and accountable public monopolies into weakly regulated and less accountable private monopolies
Shot termism over long termism- in private eindustry may look to maximise shareolher industries
Underinvestment in maintaining the rail track and in technically advanced trains by privatised railway companies said to provide an example
Sold too cheeply form sate

133
Q

A central feature of monopolistic comp is that products are differentiated. When firms try to fidderentiate their product by distinctive packaging and other promotional technqiues- known as

A

Marketing differentiation

134
Q

Sticky prices why

A

If mc changes within verticle gap still chargess p1 (where kink kinks)
As oligopolistic firms profit max which is where mc=mr so mc remains equal mr as it is veerticle

135
Q

Conclusion from oligopoly

A

Minimal incentive to change price as if increase lose market share and if decrease all others follow so dont increase in demand (inelastic)
But firms may try to reduce price- price war- eg supermarkets- matching aldi
Non-price competition- as wages are sticky, branding advertising- as seen with uk soft drinks market eg pepsi cola
Temptation to collude- so dont need to worry about how rivals react

136
Q

A

Novartis swiss pharma spent 10bn. Rand d 2016 compared to revenues 60bn

137
Q

High patent rates

Seen in bio and nano tech - 65 amd 62%
High cost rand d
Acts as barrier to entry

Q

How conc ratio set out

A

X:y
X- number of largest firms
Y- market share they hold collectively

139
Q

How performance of firms could be impacted by divorce of ownership

A

Decrease efficiency as attempt diff objectives- esp dynamic efficiency as lack of retained profit, lack innovation schumpter creative destruction
Disecon of scale- communications break down diff objectives
Financial performance as aim for diff objectives- eg rev not profit may be advance

140
Q

How to resolve divorce of ownership

A

Renumeration schemes- profit related pay/shares
Use of baords, owners and shareholders make decisions on firm and vote in agm

Intro- define divorce of owenrsip, conduct of firms, performance

Diff maximisers- trad profit but can also revenue and sales- show on idagram

How problem- impact conduct as principle agnt problem
-impact performance- efficiency disecon of scale and financial perofmrance

Solutions
- renumeration package
-shareholder boards

Overall may be problem but avoidable
