He’s my second favorite economist, right behind Thomas Sowell.

In his latest column, he explains the famous “Broken Window Fallacy”.

Excerpt:

Economic lunacy abounds, and often the most learned, including Nobel Laureates, are its primary victims. The most recent example of economic lunacy is found in a Huffington Post article titled “The Silver Lining of Japan’s Quake” written by Nathan Gardels, editor of New Perspectives Quarterly, who has also written articles for The Wall Street Journal, Los Angeles Times, New York Times and Washington Post.

Mr. Gardels says, “No one — least of all someone like myself who has experienced the existential terror of California’s regular tremors and knows the big one is coming here next — would minimize the grief, suffering and disruption caused by Japan’s massive earthquake and tsunami. But if one can look past the devastation, there is a silver lining. The need to rebuild a large swath of Japan will create huge opportunities for domestic economic growth, particularly in energy-efficient technologies, while also stimulating global demand and hastening the integration of East Asia. … By taking Japan’s mature economy down a notch, Mother Nature has accomplished what fiscal policy and the central bank could not.”

[…]Why might Japan’s and Florida’s devastation be seen as “pluses”? French economist Frederic Bastiat (1801-1850) explained it in his pamphlet “What is Seen and What is Not Seen,” saying, “There is only one difference between a bad economist and a good one: the bad economist confines himself to the visible effect; the good economist takes into account both the effect that can be seen and those effects that must be foreseen.”

Bastiat elaborated further in his “Broken Window Fallacy” parable where a vandal smashes a shopkeeper’s window.

A crowd forms, sympathizing with the shopkeeper. Soon, someone in the crowd suggests that instead of a tragedy, there might be a silver lining. Instead of the boy being a vandal, he was a public benefactor, creating economic benefits for everyone in town. Fixing the broken window creates employment for the glazier, who will then buy bread and benefit the baker, who will then buy shoes and benefit the cobbler and so forth.

Bastiat says that’s what’s seen. What is not seen is what the shopkeeper would have done with the money had his window not been smashed. He might have purchased a suit from the tailor. Therefore, an act that created a job for the glazier destroyed a job for the tailor. On top of that, had the property destruction not occurred, the shopkeeper would have had a suit and a window. Now he has just a window and as a result, he is poorer.

I learned a lot about economics from his columns.
