the economy； apportioning demand and resources accordingly。 But perfect
petition； where price is allowed such freedom； is only one of four
prevailing market structures； although market economies are dominated
by near…perfect petition； that is not maintained without a struggle。
The following are the four market structures that are at work in
economies。
Monopoly
Monopolies exist where a single supplier dominates the market and so
renders normal petitive forces largely redundant。 Price； quality and
innovation are promised； so deliver less value to the end consumer
than they might otherwise expect。 Microso。。 has a near…monopolistic grip
on the operating system market； as has Pfizer； the pharmaceutical giant；
through its patent on the drug Viagra； and British Airports Authority
（BAA）； which runs Heathrow； Gatwick and Stansted； has a similar hold on
London airports’ traffic。
Monopolies claim that without being allowed to dominate their market
it would be impossible to get sufficient economies of scale to reinvest。
That was the argument of the early railway panies and it was BAA’s
argument in 2008 in defending itself against the prospects of a governmentenforced
break…up。
In countries where monopolies are seen as being detrimental； bodies exist
to regulate the market to prevent them being too powerful。 The UK has
the petition mission （wwwpetition…mission。uk）； the
United States the Federal Trade mission （。。c。gov） and the EU
has The European mission （h。。p：//ec。europa。eu/m/petition/
index_en。html）； all keeping monopolies in check。 A duopoly is； as the name
would suggest； a particular form of monopoly with only two firms in the
market。
Oligopoly
This is where between 3 and 20 large firms dominate a market； or where
4 or 5 firms share more than 40 per cent of the market。 The danger for
consumers and suppliers alike is that these dominant firms can control
the market； to their disadvantage。 Supermarket chains in the UK； airlines；
oil exploration and refining businesses the world over operate as virtual
oligopolies。 Frequently the temptation to act in a cartel to fix prices is too
great to resist。 BA had colluded with Virgin Atlantic on at least six occasions
between August 2004 and January 2006； the Office of Fair Trading said。

Between August 2004 and January 2006； British Airways and Virgin
Atlantic； the dominant players on the route from London to US cities；
colluded with each other to fix the price of fuel surcharges。 During that
time； surcharges rose from ￡5 to ￡60 per ticket。 British Airways had to set
aside ￡350 million to deal with fines in the UK and United States。
Perfect petition
This is a utopian environment in which there are many suppliers of identical
products or services； with equal access to all the necessary resources
such as money； materials； technology and people。 There are no barriers to
entry； so businesses can enter or leave the market at will and consumers
have perfect information on every aspect of the alternative goods on offer。
petitive markets
Sometimes referred to confusingly as monopolistic petition； this rests
between oligopoly and perfect petition； but is closer to perfect petition。
Here a large number of relatively small petitors； each with small
market shares； pete with differentiated products satisfying diverse
consumer wants and needs。
ESSENTIAL ECONOMICS
Despite the peting schools of thought on how business and the economy
interact； there is at least general agreement on the most important
factors。 True； there is much disagreement on how important these factors
are and even on how they can be influenced； but on the factors themselves
there is a measure of agreement。 MBAs will need a grasp of these key issues
in order to play a full role in shaping the strategy of their organization。
Economic growth
Government’s role in economic policy is generally accepted as being to steer
a path that ensures long…term growth without leading to a general rise in
prices （see Inflation； below）。 The underlying belief is that growth in goods
and services leads to a happier； more satisfied population； while spreading
democracy； diversity； social mobility and greater all…round tolerance。 Also；
the bigger the gross domestic product （GDP） the more guns and bombs a
country can afford； both to defend itself and to impose its will on others
who are weaker。 There is certainly evidence that people judge their wellbeing
by paring themselves to others； but unfortunately as ine
goes up； so do expectations。
200 The Thirty…Day MBA
There have been many a。。empts at creating a more prehensive
measure of economic health。 Gross National Happiness （grossin
ternationalhappiness/） and the Genuine Progress Indicator （
rprogress/sustainability_indicators/genuine_progress_indicator。htm）
are a。。empts to include a range of other factors such as life expectancy； crime
rates； pollution； long…term environmental damage； resource depletion and
ine distribution； for example。
GDP is the yardstick taken to measure the economy； even though that
doesn’t necessarily say much about the level of happiness in a country。
There are a number of ways of paring GDP both between countries and
between time periods and； needless to say； economists can’t agree which is
best。
Gross domestic product
GDP is the total market value of all final goods and services produced in
a country in a one…year period。 A country’s balance sheet； like that for a
business； shows the sources and uses of funds。 A country’s GDP is usually
arrived at using the expenditure method； using the equation GDP =
consumption （spending by consumers） ＋ gross investment （spending by
business） ＋ government spending ＋ （exports – imports）。 Each ponent
of expenditure plays a part in helping increase GDP and hence economic
growth。 （See Keynes above。）
The rate of growth of GDP ma。。ers greatly。 The UK and Europe’s longrun
GDP growth rate of around 2。5 per cent will lead to a doubling of the
countries’ wealth in around three decades。 China and India； whose growth
rate routinely exceeds 8 per cent； will see average wealth double in less
than one decade。 All other things being equal； panies looking to set up
overseas will head for the countries with rapid growth in GDP。
Gross domestic product per person
Measuring a country’s total GDP misses an important consideration – the
population。 If the growth in both GDP and population were uniform there
would be no problem； but that is not the case。 Britain’s country GDP grew
at 2。75 per cent between 2003 and 2007； but as the population grew sharply
too； GDP per person grew at a rather slower 2。1 per cent。 Japan with its
shrinking population also grew its GDP per head by 2。1 per cent； matching
that of Britain and beating the United States whose growth measured in
this way was only 1。9 per cent as opposed to the 2。9 per cent the United
States reported for the economy as a whole。
