During the advance of recent chance idea within the seventeenth cen­ tury it used to be quite often held that the popularity of a big gamble supplying the payoffs :1:17 ••• ,:l: with percentages Pl, . . . , Pn is given via its anticipated n price L:~ :l:iPi. therefore, the choice challenge of selecting between various such gambles - so that it will be referred to as clients or lotteries within the sequel-was regarded as solved through maximizing the corresponding anticipated values. The well-known St. Petersburg paradox posed by means of Nicholas Bernoulli in 1728, notwithstanding, conclusively tested the truth that contributors l ponder greater than simply the anticipated worth. The solution of the St. Petersburg paradox was once proposed independently via Gabriel Cramer and Nicholas's cousin Daniel Bernoulli [BERNOULLI 1738/1954]. Their argument used to be that during a chance with payoffs :l:i the decisive components are usually not the payoffs themselves yet their subjective values u( :l:i)' in line with this argument gambles are evaluated at the foundation of the expression L:~ U(Xi)pi. This speculation -with a a little diverse interpretation of the functionality u - has been given a high-quality axiomatic starting place in 1944 through v. Neumann and Morgenstern and is referred to now because the anticipated application speculation. The ensuing version has served for a very long time because the preeminent conception of selection less than threat, in particular in its fiscal applications.

An analysis of the Allais paradox and the common ratio effect within the framework of anticipated utility theory can be found in [SEGAL 1987a]. 3. 16) implies V(ct) = u(x)f(p), V(C2) = u(y)f(q), V(cs) = u(x)f(rp) and V(C4) = u(y)f(rq), respectively. It has been shown in [SEGAL 1987a] that a possible explanation for the choice of Cl in the first pair and of C4 in the second pair of the common ratio effect is that the elasticity of f is strictly increasing. Indeed, if the elasticity of f at p, defined by pf'(p)f f(p), is strictly increasing it follows that the function f (rp ) f f (rq) is strictly increasing in r.

1). 12) where u : X -+ R is a utility function and h : [0,1] -+ [0,1] is a strictly increasing, surjective transformation function. 12). Therefore, anticipated utility theory is also known as the theory of expected utility with rank-dependent probabilities. Clearly, the expected utility model corresponds to the case where h is the identity function. The first axiomatization of the anticipated utility model is due to QUIGGIN [1982]. 12) is the following so-called weak certainty equivalent substitution axiom.

This cardinal utility is what we have called the generalized utility function. One may ask then which functions v are admissible as generalized utility functions. Obviously, since for (z,p) E B = (X x {O}) U ({O} x [0,1]) the lotteries (Oj1 - p,Zjp) represent the same distribution giving zero with certainty, v should be constant on B and by normalization equal to zero there. The monotonicity of preferences restricted to nel(x) implies that v should be a strictly increasing function of z for every fixed p 1= 0 and of p for every fixed Z 1= o.
