Consider a Samuelson model with one commodity in each period, where each consumer is endowed with one unit of the commodity in youth and none in old age and has utility function u(x0 , x1) = min(2x0 + x1, x0 + 2x1).
Compute all the stationary spot price equilibria, (x0 , x1, P , r , G, T), in which P = r = 1.
