We have read most of the mentioned papers, including the Harvard study...and they are of interest, except for one small thing....they don't have anything to do with pair trading methodology and how to implement profitable strategies. (Lest you think I am selling my training course, here are a couple of direct points) :::
Most of the money is made using the crutch trading method where you can lean on the bid or offer of the other stock.
You must envelope (and constantly modify) your bids and offers based on current price movements.
Most of your trades will be single sided, which reduces commissions (heart breaking as it is ...), and gives the trader more income.
Use historical data for selection, but not for trading basis....trade past the "zero" delta postition every couple of days, actually add to expanding trades, and reduce narrowing trades.
There is a lot more, but this should give you something to think about..
Heading for NYC (New York City!!!)....
Bye for now!!
