To: April 24th seminar attendees From: Dan Raff In re: Attached text In the seminar this Thursday, I intend to discuss a problem, an intriguing data source, and some preliminary findings. There is more detail on all of this in the attached text. (I hope to bring with me some illuminating photographic images as well as the figures.) I’m a little bit ahead of the text at the moment and I’m certainly not done with probing the data yet, so I will want both to present to you and to pick your brains a little. But the drift should be clear enough from what follows this note. I should perhaps add, in case it is not obvious, that the text is ultimately aimed at an audience that contains people trained in economics but is not confined to them.

[email protected] This revision: April 20th, 2003 Lawrence Summers, long ago in joint work on a different project, provided the itch to which this manuscript represents a provisional scratch. The text has benefited from presentations to the Penn Economic History Forum, the Development of the American Economy and Industrial Technology and Productivity groups at NBER, and the annual meetings of the Economic History Association. I learned a great deal form these audiences and had particularly helpful comments and advice from Ned Bowman, Lance Davis, Therese Flaherty, Claudia Goldin, Zvi Griliches, Margaret Levenstein, Tom Sugrue, and Robert Zevin. Charles Christianson and Sam Parker provided expert advice on a subtle accounting matter that proved to be of foundational importance.
