Maximum on a random time interval of a random walk with infinite mean

Research output: Contribution to journalArticle


Let ξ1,ξ2,… be independent, identically distributed random variables with infinite mean E[|ξ1|]=∞. Consider a random walk Sn=ξ1+⋯+ξn, a stopping time τ=min{n≥1:Sn≤0} and let Mτ=max0≤i≤τSi. We study the asymptotics for P(Mτ>x), as x→∞.
