Title: Privatisation


1
Privatisation Trust economists?
  • Sure cant

2
Economists nirvana
  • Price and quantity set by market
  • Under normal circumstances, a competitive market
    structure will allocate resources in such a way
    as to produce the goods and services which
    consumers value most highly and are prepared to
    pay for, and it does so at the lowest possible
    cost in terms of resource use. Thus, competition
    policy is based on the belief that a competitive
    market will result in economic efficiency and
    increased social welfare. (Allan Fels, Chairman
    ACCC, Lessons from International Experience
    Competition Policy The Road Ahead for Egypt, 24
    May 2001)

How it works
  • But if monopolies get in the way

Price
  • And government monopolies?
  • Worst of both worlds
  • Arbitrary price
  • Arbitrary quantity
  • No tendency to equilibrium
  • G1?

Supply
Monopoly Price
  • G3?

Pe
Marginal Revenue
  • G2?

Demand

Quantity
Monopoly Quantity

So the ideal is
  • Competitive pricing Price equal to marginal
    cost of production
  • Output sold at price of producing last unit
  • Price equal to marginal benefit of consumption
  • Market price represents marginal benefit to
    society of last unit consumed
  • Equality of marginal benefit and marginal
    cost ensures gap between total benefit and
    total cost is maximised
  • Competitive pricing thus maximises social
    welfare
  • Price equals marginal cost means price set by
    supply and demand

5
And the bogeyman is
  • Monopoly pricing
  • Price greater than marginal cost of production
  • Monopoly sets marginal cost equal to marginal
    revenue
  • Change in total revenue due to a change in output
  • Since price must fall to sell additional units,
    marginal revenue less than price
  • Output less than ideal level price higher
    welfare lower
  • Price set by intersection of marginal revenue and
    marginal cost, not supply and demand
  • Government monopoly even worse
  • Not even subject to monopoly market discipline

6
So the solution is
  • Privatise government utilities, and/or let market
    force competitive price where price equals
    marginal cost
  • Well, thats the theory, which the ACCC takes
    seriously

it's all a load of bollocks...
  • I detected some sense of impatience with
    academic theories, a desire to hear how it works
    in the real world. If that is the expectation,
    then what I say, at least at first, may
    disappoint you. Thats because one of my
    strongest guiding beliefs is that there is
    nothing more practical than theory The generally
    used framework for competition regulation is
    applied economics (Rod Shogren, Commissioner
    ACCC, Telecommunications regulation in practice
    Perspectives of a practitioner, 1999 Conference
    of Economists Business Symposium)
  • Theres just one problem

7
Flaws in theory of competitive markets
  • Proposition that competitive markets set price
    equal to marginal cost nonsense
  • Check the big picture

Where does this loss come from?
Monopoly profit level
Competitive marketaggregate profit level
Alleged competitivemarket decision point

Flaws in theory of competitive markets
  • Full logical argument in Chapter 4, Size Does
    Matter
  • Mathematical argument on website

Anyone forMathematica?
  • Bottom line
  • Theory of competitive markets based on simple
    mathematical flaw
  • Corrected, theory predicts exactly the same price
    and output for competitive market as for monopoly
  • On properly amended economic theory, Fels belief
    (that a competitive market will result in
    economic efficiency and increased social
    welfare) completely unfounded.
  • Competition policy much ado about nothing
  • And it gets worse

9
A little knowledge
  • Many other building blocks of economic theory
    already shown to be unsound
  • Undermines simplistic faith in economic theory
    professed by ACCC (one of my strongest guiding
    beliefs is that there is nothing more practical
    than theory)
  • Key issue re privatisation instability of
    multi-commodity spot markets
  • Sargan (1958), Jorgenson (1960, 1961, 1963),
    McManus (1963), Blatt (1983) prove model
    unstable
  • Either prices, quantities, or both, must diverge
    from equilibrium

10
Multi-market instability
  • Given instability, a conjecture
  • If basic commodity (electricity, water, etc.)
    priced by spot market, it will display the
    instability of underlying multi-market economy
  • Forcing spot market pricing on utility
    wholesalers probably leads to price spikes
  • Spot pricing may cause bankruptcy of suppliers
  • NSW Victoria late 1990s, California 2000
  • Competitive market model probably worst one that
    could be imposed on essential utilities
  • Killing us with misplaced kindness

11
What does the ACCC think it is doing?
  • The virulence and persistence of the attacks on
    the Commission raises the question of motive. Do
    the attackers want the unfettered right to
    establish monopolies so they can dominate the
    market and, by raising prices, earn greater
    profits? If the big business critics were
    serious about promoting the development of large
    internationally competitive Australian companies
    it would acknowledge the benefits of competition.
    Would Australias big companies be
    internationally competitive if they had to secure
    their raw materials from a monopoly supplier?
    (Australia-Israel Chamber of Commerce, Boardroom
    Lunch Allan Fels Mergers Market Power,
    Sydney 15 March 2001)

What is the ACCC actually doing?
  • What economics thinks average costs look like
  • What 95 of firms say average costs look like

  • Marginal costs highest, and determine price/output
  • Marginal costs lowest, P must be gtgt MC to cover

13
What is the ACCC actually doing?
  • Imposing impossible theoretical model on actual
    business
  • Vast majority of firms would go bankrupt if
    priced at marginal cost
  • Especially true of electricity, water, gas
  • Obsession with competition means lip service paid
    to important issues of economies of scale,
    synergies
  • Could reduce capacity of Australian industry to
    develop dynamically, in impossible pursuit of
    static efficiency goal
  • Industry public opposition partly justified,
    because
  • Theres nothing more impractical than a bad
    theory!
  • virulence and persistence of the attacks
    reflects frustration with ignorance of
    economists however

"At least we 'trancendental capitalists' can make
a buck out of privatisation..."
14
What should ACCC really be doing?
  • Assess each market on merits rather than one
    size fits all (small only!) approach of economic
    theory
  • Empirical work confirms models of pricing wrong
    (Hall Hitch 1939, Eiteman 1947, 1948, Bishop
    1948, Haines 1948, Eiteman Guthrie 1952, Means
    1972, Lee 1996, 1998, Blinder 1998)
  • Over 89 per cent indicated that marginal
    costs either declined or stayed constant with
    changes in output Finally, only four of 200
    enterprises had both elastic demand curves and
    increasing marginal costs. (Downward Lee 2001,
    reviewing Blinder)
  • Fixed costs appear to be more important in the
    real world than in economic theory. (Blinder)

15
What should motivate utility providers?
  • Not simple profit motive cost minimisation
  • Security of supply of basic commoditiesthose
    which are inputs into all production
    processesmore important than price
  • Especially essential services Electricity, Gas,
    Water, Sewerage
  • Sheils Waters Fall (Pluto Press 2000)
    illustrates what happens when supply of essential
    commodity corporatised/privatised

Privatised utilities?
We can't afford them!
