Walras'theory of capital formation. An intertemporal equilibrium reformulation

we develop a mainstream reformulation of the original Walras' model of capital accumulation.First,we prove the existence of intertemporal competitive equilibria combining a theorem due to Yannelis and Prabhokar with a lemma due to Geanakoplos.Secondly,we remedy the indeterminacy of savings allocatione of the walrasian model by introducing a storage technology.Finally we show that,for stored capital goods,the equality of rate of return emerges endogenously in equilibrium.
