| Abstract: | 
Probabilistic models of choice (between sure prospects) have become a standard 
modeling practice since the 1980s, notably through the widespread use of the 
Logit Multinomial Model pioneered by McFadden (1974). However, the idea to 
model consumer’s behavior as a probabilistic behavior, hence accounting for 
some kind of behavioral instability in the pure theory of rational choice, 
dates back to the 1930s and led to significant investigations in the 1950s. It 
is the purpose of this article to confront three attempts by economists at 
developing models of individual choice that go beyond standard ordinalist 
utility theory through introducing principles of probabilistic behavior. We 
discuss first Georgescu-Roegen’s neglected contributions to this subject, 
though he pioneered the definition of probabilistic preference in 1936 and 
came back on the subject intensively in the 1950s. We then present Marschak’s 
(and his co-authors) attempts at axiomatizing a probabilistic model of choice 
in the same period. The third contribution studied is that of Quandt, who 
provides a more operational style of modeling. This set of contributions is 
discussed against a general background of transformations of the theory of 
rational behavior and of the methods proper to it. |
