Specialization and Voluntary Exchange
![Page 3: Unit 3 Markets: not just for fleas and stocks!. Specialization and Voluntary Exchange](https://reader036.vdocuments.us/reader036/viewer/2022062516/56649d4c5503460f94a29cf7/html5/thumbnails/3.jpg)
Specialization Specialization: people/companies learn and
practice a small set of skills then work or trade with others with different skills to produce something Improves efficiency/productivity The assembly line idea
![Page 4: Unit 3 Markets: not just for fleas and stocks!. Specialization and Voluntary Exchange](https://reader036.vdocuments.us/reader036/viewer/2022062516/56649d4c5503460f94a29cf7/html5/thumbnails/4.jpg)
Why does specialization work?
Skills are developed at a deeper level people become “experts” in their field
Costs are cut because time needed to produce is decreased
Training can be more focused and in-depth
Remember: People, Stores & industries specialize
![Page 5: Unit 3 Markets: not just for fleas and stocks!. Specialization and Voluntary Exchange](https://reader036.vdocuments.us/reader036/viewer/2022062516/56649d4c5503460f94a29cf7/html5/thumbnails/5.jpg)
Examples of specialization
Doctors – cardiologists, dermatologists, dentists, podiatrists, rhinologists
![Page 6: Unit 3 Markets: not just for fleas and stocks!. Specialization and Voluntary Exchange](https://reader036.vdocuments.us/reader036/viewer/2022062516/56649d4c5503460f94a29cf7/html5/thumbnails/6.jpg)
Examples of specialization
Teachers – grade level, subject, coaches
Stores at the mall – food court, hats, electronics, shoes, clothes
Write two examples of specialization in each of these areas: Restaurant Movie Courts

How does specialization relate to voluntary exchange?
Because we specialize, we rely on others for the things we don’t produce (CAUSE AND EFFECT!)
In an exchange, BOTH sides are looking to gain something
BOTH sides gain in VOLUNTARY, NON-FRAUDULENT EXCHANGE
![Page 8: Unit 3 Markets: not just for fleas and stocks!. Specialization and Voluntary Exchange](https://reader036.vdocuments.us/reader036/viewer/2022062516/56649d4c5503460f94a29cf7/html5/thumbnails/8.jpg)
How does each side gain in these potential transactions?

SSEMI1 The student will describe how households, businesses, and governments are interdependent and interact through flows of goods, services, and money.

Market for Diamond Rings
Assume that a diamond ring costs $200
At $200 buyers are buying around 100 a day
If the price were $100, buyers would be buying 150 a day

$100
What happens if people’s income doubles?
Now, at $200, people want 150 rings.
What about at $100? Will people want more or less?

3 Conditions for Oligopoly
1. Few LARGE sellers- top 3-4 companies/sellers handle 75% of
demand
2. Identical or VERY similar products - producers less willing to take chances
3. Difficult market entry- Large firms have already paid start-up costs

Oligopolies At Work
INTERdependent pricing Firms set prices based on other
firms Price leaders: largest seller sets a
price and others follow

Oligopolies at Work
Collusion: when the major sellers set a price or production level Typically the price is above
equilibrium, but there are no cheaper substitutes
![Page 62: Unit 3 Markets: not just for fleas and stocks!. Specialization and Voluntary Exchange](https://reader036.vdocuments.us/reader036/viewer/2022062516/56649d4c5503460f94a29cf7/html5/thumbnails/62.jpg)
Oligopolies at Work
Cartels: an open form of collusion where production levels or prices are announced OPEC or DeBeers Usually short-lived because of
greed/self-interest
![Page 63: Unit 3 Markets: not just for fleas and stocks!. Specialization and Voluntary Exchange](https://reader036.vdocuments.us/reader036/viewer/2022062516/56649d4c5503460f94a29cf7/html5/thumbnails/63.jpg)
3 Conditions for Monopolies
1. Single Seller Total control of production and price setting
2. No reasonable substitutes Forces demand for good, even if prices are too
high 3. Difficult or Impossible Market Entry
Too high start-up costs or too technical field
![Page 64: Unit 3 Markets: not just for fleas and stocks!. Specialization and Voluntary Exchange](https://reader036.vdocuments.us/reader036/viewer/2022062516/56649d4c5503460f94a29cf7/html5/thumbnails/64.jpg)
Examples of Monopolies or near Monopolies
•Standard Oil, broken up in 1911
NFL – Convicted of being an illegal monopoly in 1980
•Currently under investigation.
•Potentially trying to form a monopoly in the Used Video Game market.

Not all Monopolies are “bad”
•Fayette county water authority is a “natural monopoly”
•The costs to society of having another competitor are too great
•The cost to build more rail lines would be tremendous just for someone to make a little bit of profit

Why not charge outrageous prices?
1. Consumer Demand: Increase in price of too much would cause demand of zero
2. Potential Competition: Startup costs are extremely high, but if prices got high enough, entrepreneurs would have incentive to enter
3. Government Regulation
