Using the Transfer Price Index to Set Expectations at Aston Villa

My latest post at the Transfer Price Index blog is up, and is a must read for any Aston Villa fan.  The post also dissects some of the differences between the long term (M£XI) and short term (m£XIR) transfer models, and identifies when it is appropriate to use one versus the other.  Again, it will be some time before I cross post the material here due to the desire to keep things over at that blog given the proprietary nature of the data.  Please head on over to the TPI blog and check it out!
