I don't understand a basic concept here.  How does Netflix assign a monetary
value to the improvement in rating prediction? 

For example, does rating prediction affect their inventory management?  Or is
it more of an issue of customers trusting/liking Netflix better if it's
recommendations are better?

It seems that Netflix is trying to offer a prize to stimulate innovation much
like the X-Prize worked to raise interest in privately funded rocketry/space
launching.
