α: calibrated so average coauthorship-adjusted count equals average raw count
In this note, I compare stationary distributions of the linear model Xn+1=anXn+bn, where an and bn are non-negative random variables. I show that an increase of the variability of an and/or bn causes a less equal stationary distribution in terms of the Lorenz dominance. The result is useful in studies of wealth and income distributions.
