Title: Privatisation
1Privatisation Trust economists?
2Economists 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)
3How 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
Supply
Monopoly Price

Marginal Revenue
Demand

4So 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
5And 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
6So 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
7Flaws 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?

8Flaws 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
9A 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
10Multi-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
11What 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) - Doing good even though the medicine may taste bad
12What is the ACCC actually doing?

- What 95 of firms say average costs look like

13What 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..."
14What 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)
15What 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!
