Rich longitudinal data sets

"Analyzing a rich longitudinal data set, Lisa Kahn at the Yale School of Management recently examined…" Maybe it would help if Newman and Pedulla did a little more research, so that the above could read something like this: "Analyzing a rich longitudinal data set, and not for free and in her spare time, but with a $100,000 government grant and in her spare time, Lisa Kahn…" I made up the "$100,000" figure, and I don't know on whose time Kahn assembled the cited reported, but the idea is to get as much mileage as possible out of this report and others like it, is it not?
