With β ∈ (0, 1), where ch(t) denotes the consumption of household h at time t. Suppose that u(0) = 0. The economy starts with an endowment of y > 0 units of the final good and has access to no production technology. This endowment can be saved without depreciating or gaining interest rate between periods.
