Abstract:	We prove a law of large numbers for random walks in certain kinds of i.i.d. random environments in Z d that is an extension of a result of Bolthausen et al. (2003) [4]. We use this result, along with the lace expansion for self-interacting random walks, to prove a monotonicity result for the first coordinate of the speed of the random walk under some strong assumptions on the distribution of the environment. © 2011 Elsevier B.V.
