Talks and Tutorials At my age, you get asked to give speeches and explain things to people. This is fun and interesting, and may actually be important. While the intended audience usually listens politely to my wonderful advice, they mostly ignore it. Of course, this never discourages a professor, as those of you who have been to college know. So I continue to plug away at it. I have included here my words of wisdom; some of these are papers, some are presentation overheads, originally done in PowerPoint.

Cross-Subsidy Analysis (18Kb)

My early work in Cross-Subsidy continues to be used and misused in regulatory proceedings. Recently, my friends at Sprint asked me to clarify how to apply my tests for cross-subsidy when there are more than two products (seems some intervenors got it wrong). Here's my little blurb to make sure everyone gets it right.

Annenberg Public Policy Center Report Paper (85 Kb).

I have been working with Professors Oscar Gandy (Annenberg School) and Dave Farber (Computer and Information Science) to help flesh out the Information and Society portion of the Annenberg Public Policy Center. This fall, we had several workshops involving engineers, economists, and social policy scholars which attempted to frame the issues the Center needs to be addressing. Our colleagues Pablo Spiller (UC Berkeley Economics), Richard Solomon (MIT), and Ed Baker (Penn Law) have been equal partners in this effort to organize the agenda-setting workshops. My thanks especially to Pablo for his energetic help in rounding up the hot economists for our October 27th workshop. We have produced a report with recommendations to Dean Kathleen Jamieson, including a review of all three workshops. As is usual with interdisciplinary efforts, consistency plays second fiddle to novelty and originality. Decide for yourself: download the file.

Talk to Wharton's Internet Club Presentation Overheads (20 Kb)

This is a short presentation made to World Wide Wharton - the Internet Club on December 6, 1995. The topic was electronic commerce on the Net; the topics I covered include the public policy issues which I believe will govern the development of the Net.

Talk at Stanford Economists/Engineers Workshop Paper (43 Kb)

This rather interesting workshop in March, 1995 was organized by Tim Bresnahan at the Stanford Economics Dept (and Associate Director of their Stanford Computer Industry Project). The point was to get economists (who talk about prices and resource allocation) talking with engineers (who talk about keeping the Net price-free). Since there seems to be a lot of yelling going on, this was a helpful session in that we all had the opportunity to act out.

• The Presentation Overheads (42 Kb) are also available.

Winning Economic Strategies for the 21st Century Paper (26 Kb)

Bet you just can't wait to download this and find the Secrets of the Universe Revealed! Well, this is a talk I gave at the "Asia into the Global Economy" in Seoul, Korea, in January, 1995. I figured that since they paid to get my butt halfway around the world to talk to them, they should get a suitably profound message.
