Conventional Wisdom
* Explanations that are generally accepted as true
* Conventional Wisdom is not necessarily true

Creation of Conventional Wisdom
* Often, conventional wisdom is generated by experts and journalists
* Advertising is a great tool for creating conventional wisdom

Conventional Wisdom
* A typical drug dealer’s resources?

In Reality
* Most of the people involved in illicit drug trade earn less than the minimum wage and have legitimate jobs to supplement their earnings
* It is also a highly dangerous job
* A drug dealing gang is very similar to a capitalist enterprise like McDonald’s

Why do it then?
* To succeed in an extremely competitive field
* Every street dealer aspires to one day reach the top of the pyramid
* This constitutes a “Winner-take-all” market

Winner-take-all Market
* Large amount of competition for a few highly coveted positions
* The positions usually have a lot of money, fame and respect associated with them
* Everyone usually starts off at the same level
* The large competition leads to measly pay at the lower levels
* The pyramid has a tiny apex and a very large base
The tragedy of the commons
* If there is only one player in a winner-take-all market, adding a second player might significantly improve the market output
* But if there are already a large number, adding more players will only marginally increase the market output and these players will contribute less to the economy than if they were in some other field

Winner-take-all Market
* Once a firm in such a market gets a considerable lead it is very difficult for other firms to catch-up
* Case-in-point – Google:
o The search engine market has zero switching cost
o Google had a better product than others and this gave them a huge market lead
o Even if it has a marginally better product now users will not switch their preferred search engine
o Even if the competitors have an identical product now, they still have to overcome the “brand perception gap”
o Economic and social forces form a positive feedback loop for the leader
Education
* Number of students applying to a University depends on the ranking of the University
* The better students go to the higher ranked universities
* A positive feedback loop is formed
. Impact of New Technology
* Personal Computer
o Computers were limited to large organisations
o IBM was the leader in making computers for large corporations
o Apple came out with a Personal Computer which revolutionised the market and gave it the market lead
