α: calibrated so average coauthorship-adjusted count equals average raw count
We show, by means of a counterexample, that Propositions 3, 4, and 7 in Gul (1996) [G96] are incorrect. Our example is also a counterexample to Lemma 1 in G96, which is the basis for the proofs of these propositions. We provide insight for the source of the problem in the definition of a perfect τ-theory in G96, and then offer a modification that restores these results in G96.
