“…1 Stochastic decision problems that include monetary or …nancial assets have been used to address a variety of topics including asset pricing [2,15,29,30,41,51], price dynamics [23,32,40,42,43], intertemporal substitution [26], money demand [21,33], currency substitution and exchange rates [6,34], optimal monetary policy [16,17,18,19,20,25], and monetary aggregation [3,4,5,46]. In each case, the usefulness of the model depends on the derivation of the stochastic Euler equations that characterize the model's solution.…”
