The Saint Petersburg Paradox and Its Solution

In this paper we present the main historical facts concerning the Saint Petersburg paradox, the principal solutions that have been proposed, and the results of a new experimental evidence and of a simulation of the game that shed light on the solution of this paradox, that along 300 hundred years since it was first formulated has attracted the attention of many of the most important mathematicians and economists, and that has strongly influenced the development of new concepts adopted in economic and social sciences. The main conclusion is that the behavior of the individuals is not paradoxical at all, and the paradox is intrinsic to the game.
