Linking individual and collective contests through noise level and sharing rules. Economics Letters, vol. 155, June 2017 pp. 126-130.

Abstract:

We propose the use of Nitzan’s (1991) sharing rule in collective contests as a tractable way of modelling individual contests. This proposal (i) tractably introduces noise in Tullock contests when no closed form solution in pure strategies exists, (ii) satisfies the important property of homogeneity of degree zero, (iii) can be effort or noise equivalent to a standard Tullock contest.
