PIA Sets the Table --Dickeson

Three glittering coins in the value-added fountain: 1) constancy for both quartile groups for 10 years. 2) identity of value-added as a ratio of manufactured sales for both groups during the time span, and 3) 2.75 times DOAs pricing for the entire data set.

Am I misreading the data? Are the numbers incorrectly reported? Most unlikely. Why haven't we noticed this before? Perhaps it's because we never viewed the data as a time series until now.
