Dear Steven,

I agree with this need for calibration, but it seems unlikely that this will
be achieved within one RAE round. Thereafter, you have to wait four years
for a second measurement point. :-) Furthermore, there is the problem of how
to combine the multivariate regression with the time series perspective. The
former will provide you with comparative statics, but not with insights in
the dynamics of the system (autocorrelation problems!). It seems that you
are formulating a research program rather than a policy measure.

Perhaps, I lost you. I donwloaded the report of the UK government which you
cited, but it is more on technology and innovation than on science. After a
lot of the usual rethoric, they advise to develop "a metrics" without
specifying anything.

I lost your point.
