The 2005 Nobel Prize in Economics is scheduled to be announced on Monday.
The top candidate whose work I am most familiar with is Oliver Williamson in contract/transaction cost theory.
Here is a link to an actual betting market that they had for the 2004 Nobel Prize in Economics (it has not been updated for 2005). You could buy shares in an economist and then you win a share of the proceeds if that economist wins the Nobel prize (it did actually predict the winner last year).
Sadly, my teaching of high school economics and "groundbreaking" work in the area of paper footballs and paper airplanes is once again likely to be overlooked by the Nobel committee...
Automatic bonus points for any of my students that can look up and give a quick summary of Williamson's contribution to the field of economics (in your own words, not copied directly from somewhere of course).
