The quote in full reads:
The reason that big data hasn’t taken economics by storm is that aggregation is really hard.
As near as I can tell, the quote originates from Klint Finley.
Let’s assume aggregation is “really hard,” which of necessity means it is also expensive.
Might be nice, useful, interesting, etc., to have “all” the available data for a subject organized together, what is the financial (or other) incentive to make it so?
And that incentive has to be out weigh the expense of reaching that goal. By some stated margin.
Suggestions on how to develop such a metric?
