And you thought freakonomics was dead:
That's from the paper "On the Efficiency of AC/DC: Bon Scott vs. Brian Johnson by the University of Calgary's Robert Oxoby that is in the current issue (July 2009) of Economic Inquiries. Here's an unblocked version also available here.
And lest you think we economists are a bunch of tweed-wearing, bow-tie tightening, SAS-programming, wine-sipping, integral-solving, unassuming*, humorless geeks, here's a bit from the acknowledgements in the paper.
Take a chance while you've still got the choice. Cheers, Dr. Oxoby.
*Show me an economist who is truly unassuming and I'll show you an out-of work economist.
