              			Maximization of the Kullback–Leibler information is known to result in general Esscher
transformations. The Bose–Einstein and Fermi–Dirac statistics in a probability space $(\Omega,
\mathcal{F},P)$ give rise to another kind of information, namely,
$$
S_B=\int \log\bigg(1+\frac{dP}{dQ}\bigg)\,dQ+ \int \log\bigg(1+\frac{dQ}{dP}\bigg)\,dP
$$
for the Bose statistics and
$$
S_F =\int\log\bigg(\frac{dP}{dQ}-1\bigg)\,dQ -\int\log\bigg(1-\frac{dQ}{dP}\bigg)\,dP, \qquad
\frac{dP}{dQ} >1,
$$
for the Fermi statistics. This information generates measure transformations corresponding to
these statistics. In the presence of a payoff matrix, these transformations vary in accordance
with the integral equations given in the paper. We give examples of financial games corresponding
to Bose and Fermi statistics.
