Hi Brian, and thanks for the inspirational overview. I totally agree with it.
But if I go back with this to my colleague (I won't meet him at the cafe after close-of-business today because I'm travelling, but tomorrow might well be), he will claim that this is too much of a quasi-philosophical explanation. A simple way of getting the number is simply checking the revenue of the key companies involved in the business. The next "quantum leap" in innovation might be round the corner and completely change our paradigms for estimating the size of a market, but until this happens, if we are assigning a value to it, we are making a bet. The "third level" you mention is what my colleague calls "ecosystem services". Interestingly, their value can be estimated as well (I have started to work a few years ago on one of these cases); but for the time being, I will stick to "level 1", considering the thread open for a couple of days, should any other folk wish to drop a line. Thanks also for the "good travels" in Italy...in fact I am an Italian citizen and a resident, but I travel quite a lot up and down "The boot", as we call it (today towards the AC/DC gig in Imola...) Best regards!
