Gene Callahan’s Economics for Real People, pp79 - 80:
PEOPLE OFTEN USE words from the arenas of games and war to describe the market. We hear that international competition will result in some nations being “winners” and others “losers.” We read a headline that some company has “crushed” its competition, or that the U.S. is at “economic war” with Japan or OPEC.
Employed as loose metaphors, such terms are useful. But the analogy does not extend very far. The key difference between a game and the market process is that, in the market, all participants gain from voluntary exchange. Kyle, Stephen, Rachel, and Emma were all better off after completing their trades than they had been beforehand.
Imagine that you and I open competing software companies. Over time, it becomes apparent that consumers prefer your product. I close my business down, and you wind up hiring me as your lead programmer. Now, in one sense, I lost and you won. But in a much more important sense, everyone won. I now have a role in fulfilling the needs of the consumers to which I am better suited than previously, you have a new lead programmer, and the consumers have a better software company. This stands in sharp contrast to sports, where the winner gets a “1” in the standings, the loser a “0,” and everyone goes home. It is also very different from war, where the winners may do what they want with the losers, including annihilate them.
To take the metaphors of games and war too literally in describing the market process is a misapprehension of its nature. Market competition is different than sports and war in crucial ways. It doesn’t exist to pick “winners” and “losers”: it exists to allow everyone to find a place in the scheme of production in which they can best satisfy the wishes of consumers.
It is just as mistaken to view international markets as pitting one nation against another as it is to view the domestic market as pitting employees against employers, or producers against consumers. In a market economy, whether it is domestic or international in scope, everyone’s standard of living can rise at once. America has not lost if Japan or China should become wealthier than the U.S. An increase in the standard of living anywhere benefits all people who are economically integrated with the area in question.
The discovery of the law of association was a great achievement of the classical economists. It points the way toward social harmony, showing that the powerful and the weak have a better way to relate to each other than through exploitation. The nature of the market as a network of voluntary exchanges means that each participant must feel he is benefiting from a trade, or he would not enter into it.
With the basics of multiperson exchange under our belts, we can move on to economic calculation, and the tool that made it possible—money.
