Economist Andrew Lawrence came up with the Skyscraper’s Index which shows the correlation between the construction of the world tallest buildings and economic cycles. His thesis is that in years in which the tallest building is complete or near completion, the economy downturns. To me it seems really odd and I can’t find any reason behind this correlation or coincidence; I guess this is what they call in regression analysis a Spurious Correlation, where observation are correlated completely by chance.

* I’m not sure whether Burj Dubai will actually be completed or not, so who knows maybe Shanghai building will be the tallest building by 2012.
