Delivereads — genius idea, a mailing list for Kindles. Yes, if you can send email then you can be a Kindle publisher. (via Sacha Judd)
Abnormal Returns From the Common Stock Investments of Members of the U.S. House of Representatives — We measure abnormal returns for more than 16,000 common stock transactions made by approximately 300 House delegates from 1985 to 2001. Consistent with the study of Senatorial trading activity, we find stocks purchased by Representatives also earn significant positive abnormal returns (albeit considerably smaller returns). A portfolio that mimics the purchases of House Members beats the market by 55 basis points per month (approximately 6% annually). (via Ellen Miller)
Google News Archive Ends — hypothesizes that old material was “too hard” to make sense of, but that seems unlikely to me. More likely is that it wasn’t useful enough to their machine learning efforts. Newspapers can have their scanned/OCRed content for free now the program is being closed.
Week Report 310 — BERG’s first (that I’ve seen) video report of the week, and it’s a cracker. No newsreel, just some really clever evocation of the mood of the place and the nature of the projects. I continue to be impressed by the BERG crew’s conscious creation of culture.
