When I was a girl, I spent my summers in the beautiful redwood forests of the California coast. One lesson was always drilled into me: prevent forest fires. We learned to put out campfires correctly, be careful with matches and in general avoid anything that might damage those splendid forests.
What was my surprise when I heard a naturalist discussing how occasional forest fires could be acceptable and even healthy for the redwoods. The idea was shocking, but as time has gone on it has gained more and more acceptance among the expert community. A fire rushing through those majestic trees doesn´t kill most of them, and it does clear out the underbrush and even make the land more fertile so that seedlings can grow. Fires, if controlled, are often followed by a burst of new growth and health in the forest. In fact, there have been experiments with actually setting controlled fires when fire prevention had been so successful that there had been no forest fires for a long period.
I was reminded of this lesson last month, as we watched the financial world as we knew it melt down before our eyes. As banks crumbled and vanished, we bemoaned the loss of that impressive structure that had underpinned our prosperity, and we attempted to run for safety. And as the fire raged, we watched in panic and wondered what would be left when it finally went out.
But what if economies are like those redwood forests? For years I have shown slides of the continued growth, not punctuated by recessions, of the U.S. economy for almost two decades, and we have marveled at the successes of monetary policy in perpetuating constant growth. Maybe instead of marveling, we should worry for the health of an economy that goes without a contraction for so long. Maybe forest fires are also good for the economy.
