Summary

Two reports, related Description of new dataset

Exciting Comprehensive

Some beginning analysis Relationship (econometrically) between use of

intellectual property and various characteristics

Report 1: Comments, in general

Give me more confidence statistically T-stats and p-values, std. error, std. dev.

Probably all ok with your large numbers, but show them just the same

Give me more information about the variation in your data

Explore some of the “unstated” relationships and potential explanations for what you see, or don’t see, in the data

Yes, curved, but only marginally 1bn

Report 2: Amount of IP

One patent ≠ another patent, same with TM Weight / correct for

Cites? Claims? Words? Family size?

Table 3: What share exited, when? Age dynamics of time By Sector!!!

Table 7: Probit Regressions Give me some reduced form models testing specific

RQ’s or H1, H2, etc. prior to “full model” Control from size/quality of IP

Shameless plug

13,000 technology startups Software and allied, Biotechnology, Medical Devices, other sectors

In the field now, US Mit der ZEW, jetz in Feld.

In sum

Heroic effort, wonderful new data Hooray!

More statistics, more analysis Match up with survey data (extant, generate)

One Appendix on the CIS Self-generate survey data

Looking fwd. to what you do with it
