The article is devoted to the Ramsey–Kass–Koopmans model. We consider an auxiliary system of differential equations, which is analogous to the system that arises in the case of constancy of the stationary rate of savings. We found that systems of this class are solved in quadrature. This allows us to find approximate solutions to the system describing the original model.
Keywords: mathematical model, Ramsey–Kass–Koopmans problem, competitive households, stationary savings rate.
