We consider a random record model from a continuous parent X with cumulative distribution function F, where the number of available observations is geometrically distributed. We show that, if E(|X|) is finite, then so is E(|Rn|) whenever Rn, the nth upper record value, exists. We prove that appropriately chosen subsequences of E(Rn) characterize F and subsequences of E(Rn − Rn−1) identify F up to a location shift. We discuss some applications to the identification of wage-offer distributions in job search models.

We consider a random record model from a continuous parent X with cumulative distribution function F, where the number of available observations is geometrically distributed. We show that, if E(|X|) is finite, then so is E(|R n |) whenever R n , the nth upper record value, exists. We prove that appropriately chosen subsequences of E(R n ) characterize F and subsequences of E(R n − R n−1) identify F up to a location shift. We discuss some applications to the identification of wage-offer distributions in job search models.

We consider a sequence, of random length M, of independent, continuous observations X i , 1 ≤ i ≤ M, where M is geometric, X 1 has cumulative distribution function (CDF) G, and X i , i ≥ 2, have CDF F. Let N be the number of upper records and let R n , n ≥ 1, be the nth record value. We show that N is independent of F if and only if G(x) = G 0(F(x)) for some CDF G 0, and that if E(|X 2|) is finite then so is E(|R n |), n ≥ 2, whenever N ≥ n or N = n. We prove that the distribution of N, along with appropriately chosen subsequences of E(R n ), characterize F and G and, along with subsequences of E(R n - R n-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.

We consider a sequence, of random length M, of independent, continuous observations Xi, 1 ≤ i ≤ M, where M is geometric, X1 has cumulative distribution function (CDF) G, and Xi, i ≥ 2, have CDF F. Let N be the number of upper records and let Rn, n ≥ 1, be the nth record value. We show that N is independent of F if and only if G(x) = G0(F(x)) for some CDF G0, and that if E(|X2|) is finite then so is E(|Rn|), 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.

We look at the issue of obtaining a variance like measure associated with probability distributions over ordinal sets. We call these dissonance measures. We specify some general properties desired in these dissonance measures. The centrality of the cumulative distribution function in formulating the concept of dissonance is pointed out. We introduce some specific examples of measures of dissonance.
