The Indestructible Nature of IdeasThe Indestructible Nature of Ideas

Does division of labor increase Does division of labor increase productivity?productivity?Does division of labor increase Does division of labor increase productivity?productivity?

Yes. People become more proficient in one activity which results in greater output per person

Specialization of labor :Specialization of labor :Specialization of labor :Specialization of labor :

The division of labor into specialized activities.

Adam Smith: Adam Smith:

“One man draws out the wire, another straightens it, a third cuts it, a fourth points it, a fifth grinds it at the top for receiving the head; to make the head requires two or three distinct operations, to put it on is a peculiar business, ...........”

The reason for such division of labor, he noted, is that these 10 people could make as many as 48,000 pins in a day. If they had each worked separately and independently, they could not have produced more than 200.

Example 1:

Absolute Advantage:Absolute Advantage:Absolute Advantage:Absolute Advantage: A country’s ability to produce a good

using fewer resources than the country with which it trades

The Theory of Absolute Advantage states that a country should completely specialize and produce the good in which it has absolute advantage.

Comparative Advantage:Comparative Advantage:Comparative Advantage:Comparative Advantage: A country’s ability to produce a

good at a lower opportunity cost than the country with which it trades

The Theory of Comparative Advantage states that a country should completely specialize and produce the good in which it has comparative advantage.

No! Not unless it also has a comparative advantage in those goods and services

Because by so doing its opportunity costs may be too high
