This paper studies the distribution of a family of rankings, which includes Google's PageRank, on a directed configuration model. In particular, it is shown that the distribution of the rank of a randomly chosen node in the graph converges in distribution to a finite random variableR *that can be written as a linear combination of i.i.d. copies of the attracting endogenous solution to a stochastic fixed‐point equation of the form R = D∑ i = 1 NC iR i + Q , where ( Q , N , { C i } ) is a real‐valued vector withN ∈ { 0 , 1 , 2 , … } , P ( | Q | > 0 ) > 0 , and the { R i } are i.i.d. copies of R , independent of ( Q , N , { C i } ) . Moreover, we provide precise asymptotics for the limitR * , which when the in‐degree distribution in the directed configuration model has a power law imply a power law distribution forR *with the same exponent. © 2016 Wiley Periodicals, Inc.
