    Definitions: Adam Smith, biography from the Concise Encyclopedia of Economics
    Smith saw the main cause of prosperity as increasing division of labor. Using the famous example of pins, Smith asserted that ten workers could produce 48,000 pins per day if each of eighteen specialized tasks was assigned to particular workers. Average productivity: 4,800 pins per worker per day. But absent the division of labor, a worker would be lucky to produce even one pin per day....

    Division of labor and specialization in corporations: Corporations, from the Concise Encyclopedia of Economics
    To look askance at executives who supply little or none of the corporation's capital, as many of the corporation's critics do, is really to condemn the division of labor and specialization of function. Corporate officers operate businesses whose capital requirements far exceed their personal saving or the amounts they would be willing or able to borrow....
    Specialization and Wealth, by Dwight Lee. At CommonSenseEconomics.com. Also available: audio.
    A remarkable degree of social cooperation emerges through market communication. Now, let's consider some of the advantages we realize from that cooperation. At a general level these advantages are obvious. It simply makes sense that we can produce more if our actions are in harmony than if we are working at cross-purposes. But to really understand economics, we must consider the link between cooperation and productivity in detail.

    Wealth seldom comes as manna from heaven. It has to be produced by applying human effort, intelligence, and patience to natural endowments that yield their bounty reluctantly. This should be obvious. But one measure of the success of the marketplace at improving our productive powers is that it has become all too easy for people to assume that wealth is part of the natural order of things. Academics and policy wonks consider the distribution of wealth to be the primary issue, while dismissing any concern that their policy prescriptions could hamper its production. They drone on and on about the causes of poverty (or the "improper" distribution of wealth), apparently unaware that determining the causes of wealth is the serious challenge....

    The Division of Labor is Limited by the Extent of the Market, Book I, Chapter 3 in The Wealth of Nations by Adam Smith
    As it is the power of exchanging that gives occasion to the division of labour, so the extent of this division must always be limited by the extent of that power, or, in other words, by the extent of the market. When the market is very small, no person can have any encouragement to dedicate himself entirely to one employment, for want of the power to exchange all that surplus part of the produce of his own labour, which is over and above his own consumption, for such parts of the produce of other men's labour as he has occasion for....

    Smith's pin factory example: par. I.I.3 in The Wealth of Nations by Adam Smith
    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....

    Part 2, Chapter 8, Human Society in Human Action by Ludwig von Mises
    The principle of the division of labor is one of the great basic principles of cosmic becoming and evolutionary change. The biologists were right in borrowing the concept of the division of labor from social philosophy and in adapting it to their field of investigation. There is division of labor between the various parts of any living organism.
