Price Theory Unstudied By Mainstream Economists

This seems hard to credit:

"if current graduate students know anything of price theory, it would have had to have been self-taught, because it is no longer on the curriculum on the 'best' American departments. (Except Chicago where it hangs in by a whisker...)" -- Angus Deaton (2007). "Letter from America - Random Walks by Young Economists", Royal Economic Society Newsletter (April)

Instead, economists study how to statistically analyze intrument variables. (I hope D-Squared will find the reference of interest.)
