The K word

Jerry Jordan makes the case against what he call K-brand economics. (HT: Dan Klein) Very well done. An excerpt:

It is tempting to think that the Soviets perfected negative-value-added investment — the stuff produced is worth less than the value of the resources to produce it. However, most families have experienced this first hand.

It usually surfaces with an entrepreneurial adolescent deciding it would be a good idea to sell lemonade at the curbside to passersby

Parents, wanting to encourage the idea that working and making money is a good idea, drive around to buy the lemon, sugar, designer bottled water, cups, spoons, napkins, a sign or two, and probably a paper table cloth.

Aside from time and gas, the outing adds up to something north of $10. At the opening of business the next day, the kids find business is slow to nonexistent at $1 per cup. So, they start to learn about market demand and find that business becomes so brisk at only 10 cents per cup that they are sold out by noon, having served 70 cups of lemonade and hauled in $7.

The excited lunch-time conversation is about expanding the business. A stand across the street to catch traffic going the opposite direction; maybe one around the corner for the cross-street traffic. The kids see growing revenue; the “investors” see mounting losses.

There is a strand of economics, we’ll call it the K-brand, that sees all this as worthwhile. They add together the $10 spent by the parents to back the venture and the $7 spent by the customers and conclude that an additional $17 of spending is clearly a good thing. Surely, the neighborhood economy has been stimulated.

To the family it is a loss, chalked up as a form of consumption. If this were a business enterprise it would be a write-off. In classical economics it is a “mal-investment.”
