Data available on my website

Unless otherwise noted, data files are in stata 6 or stata 7 format, which is readable by stata or tsp. If you wish another format, I suggest you acquire stat/transfer, an excellent program that converts data files to and from a large variety of formats.

NBER patent data files (Hall, Jaffe, and Trajtenberg 2002)

Note that an updating project is underway under the direction of Iain Cockburn, Boston University but this will not be complete until 2007 or 2008. Further information will be posted here as it becomes available. In particular, work is underway on a patent name-matching project which will standardize patent assignee names, and match them to the names of firms in the Compustat files. This work is based to some extent on work already done by researchers at the Institute of Fiscal Studies (London), Katholieke Universiteit Leuven, and Universita Bocconi (Milano), but the algorithms have to be modified extensively for USPTO data.

2002 Updates to NBER patent data:

· Documentation for NBER data

· Data on patents issued 1963-2002 in stata 7 format     (updated 4 Dec 04 to add asscode and 2002 patent assignee number)

· Raw patsic02 from the USPTO (contains SIC assignment and full subclass, also tables of SICs, Class, and State/Country codes)

· List of standardized 2002 patent assignee names corresponding to pat63_02 in stata 7 format

· Citations for patents issued 1975-2002 in stata format

· Patenting organization name-matching project for 2002 update

Manufacturing panel data (you must be a Compustat subscriber to use these datasets):

• Compustat header file (list of firms) as of 1995
• Documentation file for 1995 panel
• 1995 manufacturing panel
• 1995 manufacturing panel in Excel format
• 1995 panel with patent counts
• Patent panel used in Hall, Jaffe, and Trajtenberg (RJE 2004)

Older datasets (pre-1999 papers)
