Great work on your week 3 AR. I want to place
this concept in a theoretical light. When Adam
Smith wrote the Wealth of Nations in 1776, one
of his important insights had to do with the
role of specialization in the creation of
wealth. If people specialize, they become very
efficient at certain types of work. They can do
what they do well and then exchange their work
for the production of others, who specialize in
what they do well. The result is more efficient
production and an increase in wealth. Adam Smith
provided the following example in the Wealth of
Nations.
To take an example, therefore, from a very
trifling manufacture, but one in which the
division of labour has been very often taken
notice of, the trade of a pin−maker: a
workman not educated to this business (which
the division of labour has rendered a
distinct trade, nor acquainted with the use
of the machinery employed in it (to the
invention of which the same division of
labour has probably given occasion), could
scarce, perhaps, with his utmost industry,
make one pin in a day, and certainly could
not make twenty. But in the way in which
this business is now carried on, not only
the whole work is a peculiar trade, but it
is divided into a number of branches, of
which the greater part are likewise peculiar
trades. One man draws out the wire; another
straights 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; to
whiten the pins is another ; it is even a
trade by itself to put them into the paper ;
and the important business of making a pin
is, in this manner, divided into about
eighteen distinct operations, which, in some
manufactories, are all performed by distinct
hands, though in others the same man will
sometimes perform two or three of them. I
have seen a small manufactory of this kind,
where ten men only were employed, and where
some of them consequently performed two or
three distinct operations. But though they
were very poor, and therefore but
indifferently accommodated with the
necessary machinery, they could, when they
exerted themselves, make among them about
twelve pounds of pins in a day. There are in
a pound upwards of four thousand pins of a
middling size. Those ten persons, therefore,
could make among them upwards of forty−eight
thousand pins in a day. Each person,
therefore, making a tenth part of
forty−eight thousand pins, might be
considered as making four thousand eight
hundred pins in a day. But if they had all
wrought separately and independently, and
without any of them having been educated to
this peculiar business, they certainly could
not each of them have made twenty, perhaps
not one pin in a day; that is, certainly,
not the two hundred and fortieth, perhaps
not the four thousand eight hundredth, part
of what they are at present capable of
performing, in consequence of a proper
division and combination of their different
operations.
This theory was completed by David Ricardo, who
developed the theory of Comparative Advantage.
Comparative Advantage says that the person
(company, country, etc.) with the least
opportunity cost involved in producing the
product should produce it and the person with a
higher opportunity cost should purchase it.
Through this trade, wealth is maximized. Thus,
if a company in India has a lower opportunity
cost involved in data input than a company in
America, both companies are better off if the
Indian company does the data input function,
while the American company focuses its resources
on what it does best. In this way, wealth is
maximized.
This theory works at all levels. The reason that
we are individually better off learning
particular skills, specializing and selling our
labor, is because we can then become the lower
opportunity cost provider in a certain area and
exchange our talents and skills for things
produced by others. Without this process
described by Smith and Ricardo, none of us would
have living standards beyond that of a caveman,
if we could survive at all.

The recent change that is often called
outsourcing stems from a dramatic reduction in
transaction costs facilitated by computers and
fiber-optics. While any gain obtained in the
past by sending work to India would have been
overwhelmed by shipping costs and time delays,
today these costs are minimal because of
computers, fiber-optics and the Internet. These
new tools are creating greater opportunities for
more efficiency and greater wealth creation.
