We estimate the process underlying the pricing of American options by using higher-order lattices combined with a multigrid method. This paper also tests whether the risk-neutral densities given from American options provide a good forecasting tool. We use a nonparametric test of the densities...

We develop a dual currency search model to study equilibrium currency exchange and the determination of nominal exchange rates. Agents hold portfolios consisting of two distinct currencies. We study equilibria in which the two currencies are identical and equilibria in which the two currencies...
