“Was Adam Smith wrong?’
”Indeed, Adam Smith, in his depiction of the division of labor in a pin factory and his timeless prose on the invisible hand and the self-interest of the butcher, offers some of the greatest explanations and defenses of capitalism ever written, even some 230 years later. I consider Smith a great thinker, and a hero of liberty. That doesn’t mean he was never wrong; particularly when it comes to the question of value.
Smith’s thoughts on the derivation of value in his Wealth of Nations laid the groundwork in this area for later thinkers like David Ricardo (another brilliant mind who was right about many other things) and eventually Karl Marx.
Smith essentially, though somewhat confusedly, argued that the value of any good was ultimately derived from the amount of labor it took to produce. Money or commodity prices reflected only the nominal but never the real value of a good. In this way he described the different prices of different goods as a simple formula:
“If among a nation of hunters, for example, it usually costs twice the labor to kill a beaver which it does to kill a deer, one beaver should naturally exchange for or be worth two deer.” (The Wealth of Nations, Book I, Chapter VII)
Smith elaborated further by describing other costs of producing a good, including the role of the entrepreneur and capitalist and the profits they require.
The problem with Smith’s analysis is not that the cost of production has no link to the value or money price of a good – indeed, the two are closely connected. He merely had the relationship backwards.
In reality, prices reflect the money equivalent of the value a buyer places on a good. That is to say, an individual who wishes to have a good places an entirely subjective value upon that good as compared to other goods, and the difference is typically expressed in terms of money. If in Smith’s example no one cared for beavers, the cost of killing a beaver wouldn’t matter; the beaver would sell for little or nothing. There is no one value of a good, but each individual values each good differently, as compared to other goods. It is the same for Smith’s supposedly changeless measure of value, labor. An hour of the same kind of labor may be valued (or disdained) to different degrees by different people.
