After the Nobel flops for Literature (Herta Müller is ok..., but the Eurocentrism of the Nobel Literature commitee remains obvious; e.g. how can you still keep out Philip Roth or Michael Ondaatje, that after having ignored all US & Canadian top writers for the last several decades?! ) and Peace (I guess nobody beats Greg Mankiw in describing that), let us hope for a vindication with the '09 Nobel Economics prize.
It's simple, I will be consistent :-), thus my bet for tomorrow is: Hart, Holmstrom and Williamson for their contribution to the theory of the firm. This despite that others/ more or less official odds would suggest otherwise (see for instance Thomson Reuters, Ladbrokes, Kellogg & Northwestern), and although my personal favourite is Dale Mortensen (for developing search theory, with Peter Diamond and Chris Pissarides). Of course you might know that I am part of Dale's LMDG group in Aarhus and for instance just returned from a great conference program he put together in Sandbjerg, but, bias aside :-), I cannot imagine search theory not being rewarded with the Nobel within the next couple of years.
