Code and Data

• Patent data:
  • Patent data updated to 2023
  • If you want to replicate the results of KPSS (2017), see this replication kit
  • Mike Woeppel has some additional cleaned data from USPTO
• Here's a little tool I built for mapping SIC codes to Fama-French industry classifications in Python.
• Long ago, I posted some SAS code to estimate regressions with Fama-Macbeth, clustered standard errors, or fixed effects in SAS. This code complements the Stata code available on Mitchell Petersen's Programming Advice page. I haven't used SAS in many years and cannot say whether this is still the best way to do things.
• SAS code to estimate PIN (as in Easley, Kiefer, O'Hara & Paperman, 1996, Journal of Finance). This is really old!
