This paper gives an overview of simulation based procedures, which have proved to be efficient in valuing American options and therefore real options. Many of them integrate sequential stochastic simulations in the backward recursive programming approach to determine the early-exercise frontier....

We study the convergence of the binomial, trinomial, and more generally $m$-nomial tree schemes when evaluating certain European path-independent options in the Black-Scholes setting. To our knowledge, the results here are the first for trinomial trees. Our main result provides formulae for the...
