Abstract

A stochastic model of the growth of household (family) savings is considered. Conditions are identified such that there exists a solution to the mixed parabolic problem for the distribution density of households in terms of savings. Using Laguerre polynomials, a solution is constructed explicitly in the form of a functional series for an initial boundary value problem with a nonlocal boundary condition. An economic interpretation of this nonlocal condition is outlined.
