I read Nobel in Economics as 'Nobel in maths (largely statistical optimization) and behavioural psychology'. I personally believe the field adds significant value to society.
That said, I do think the award is rather liberally given away. We credit scientists only when their theories test out in practice with sufficient evidence whereas we are more willing to give economists a pass in the name of 'not enough data' or 'valid under certain conditions' . I think we should award only the fundamental time tested truths (statistical or otherwise) which are so entrenched in the way of the world that its discovery has little or no bearing on its exact function. This would award Nash/Selten but not Merton/Scholes. The basic option pricing ended up being just a bunch of really cool but limited equations which tend to be self fulfilling prophecies until when they don't.
ok Apoorv, if you want credentials, here's Hayek's speech agreeing with me.
