Characterizations in a random record model with a non-identically distributed initial record
Abstract: We consider a sequence of random length M of independent absolutely continuous observations Xi, 1 = i = M, where M is geometric, X1 has cdf G, and Xi, i = 2, have cdf F. Let N be the number of upper records and Rn, n = 1, be the nth record value. We show that N is free of F if and only if G(x) = G0(F (x)) for some cdf G0 and that if E (|X2|) is finite so is E |Rn|) for n = 2 whenever N = n or N = n. We prove that the distribution of N along with appropriately chosen subsequences of E(Rn) characterize F and G, and along with subsequences of E Rn - Rn-1) characterize F and G up to a common location shift. We discuss some applications to the identification of the wage offer distribution in job search models.
