The Skyscraper Index

Never heard of this before but it makes total sense. From WikiPedia:
The Skyscraper Index
The Skyscraper Index is a concept put forward in January 1999 by Andrew Lawrence, research director at Dresdner Kleinwort Wasserstein, which showed that the world's tallest buildings have risen on the eve of economic downturns. Business cycles and skyscraper construction correlate in such a way that investment in skyscrapers peaks when cyclical growth is exhausted and the economy is ready for recession. The buildings may actually be completed after the onset of the recession or later, when another business cycle pulls the economy up, or even cancelled. Unlike earlier instances of similar reasoning ("height is a barometer of boom"), Lawrence used skyscraper projects as a predictor of economic crisis, not boom.

Lawrence started his paper as a joke (emphasized by a title referencing a comedy show) and based his "index" on mere comparison of historical data, primarily from the United States experience. He dismissed overall construction and investment statistics, focusing only on record-breaking projects. The first notable example was the Panic of 1907. Two record-breaking skyscrapers, the Singer Building and Metropolitan Life Insurance Company Tower, were launched in New York before the panic and completed in 1908 and 1909, respectively. Met Life remained the world's tallest building until 1913. Another string of supertall towers - 40 Wall Street, Chrysler Building, Empire State Building - was launched shortly before to the Wall Street Crash of 1929. The next record holders, World Trade Center towers and Sears Tower, opened up in 1973, during the 1973�1974 stock market crash and the 1973 oil crisis. The last example available to Lawrence, Petronas Twin Towers, opened up in the wake of the 1997 Asian Financial Crisis and held the world height record for five years. Lawrence linked the phenomenon to overinvestment, speculation and monetary expansion but did not elaborate these underlying issues. The concept was revived in 2005, when Fortune warily observed five media corporations investing in new skyscrapers on Manhattan (none of them, including the tallest New York Times Building, broke any records).

The intuitively simple concept, publicized by business press in 1999, has been cross-checked within the framework of the Austrian Business Cycle Theory, itself borrowing on Richard Cantillon's eighteenth-century theories. Thornton (2005) listed three Cantillon effects that make skyscraper index valid. First, a decline in interest rates at the onset of a boom drives land prices. Second, a decline in interest rates allows increase in average size of a firm, creating demand for larger office spaces. Third, low interest rates provide investment to construction technologies that enable developers to break earlier records. All three factors peak at the end of growth period.
And of course, we see the writing on the wall for Dubai. Fascinating idea... Posted by DaveH at January 22, 2010 8:47 PM
