The Skyscraper Index

A skyscraper is a thing made from a sunny outlook. A skyscraper of record-breaking height is a thing made often from a mix of cheap money, debt and a fat scoop of hubris on top.

Somewhere a real estate man with dirt under his shoes and drywall dust on his shoulder must’ve had a hunch that skyscraper booms happen just as things go bust. But it took an economist to put it down on paper and create an index.

In 1999, economist Andrew Lawrence did just that. He created the Skyscraper Index. It showed that the tallest skyscrapers sprouted just as business withered.

Its ability to predict collapse is surprisingly accurate…

In a 2005 paper, economist Mark Thornton took a stab at vetting the index. He wrote that “the Skyscraper Index… does have a good record in predicting important downturns in the economy.” And most recently, Erste Group Research released a report in March that calls the track record of the Skyscraper Index “impressive.”

Here’s how it worked in Dubai. The Burj Khalifa took the crown of world’s tallest building from Taiwan’s Taipei 101 in 2007 — just before the onset of the global financial crisis. Here the Skyscraper Index worked perfectly. (And Taipei 101 itself fits the theory of the index too. Construction began in 1999, just before the tech bubble reached its peak.) (more)
