Аннотация:We study the mean field games equations, consisting of the coupled
Kolmogorov-Fokker-Planck and Hamilton-Jacobi-Bellman equations. The equations
are complemented by initial and terminal conditions. It is shown that with some
specific choice of data, this problem can be reduced to solving a quadratically
nonlinear system of ODEs. This situation occurs naturally in economic
applications. As an example, the problem of forming an investor's opinion on an
asset is considered.
