To Polly Cleveland and Pat Gunning: I was referring to the claim that spectrum rents owe their existence to the artificially created scarcity of licenses. That is, rents might have been zero if it hadn't been for the limitation of entry. The claim is made, for instance, by B. Owen, J. Beebe and W. Manning in _Television Economics_ (1976). I was interested in any comments on such a pesumably extreme position. As it seems, most critics admit that spectrum _is_ scarce, and rents are necessarily generated. Although, according to Mark Blaug, it is spectrum rent which is perhaps the perfect Georgist rent for us today, it is not my intention to divert attention from the discussion of LVT. However, any replies offlist are welcome. Yuri Tulupenko
