Here we develop a new approach for pricing both continuous-time and discrete-time American options which is based on the fact that an American option is equivalent to a European option with a consumption process involved. This approach admits construction of an upper bound (a lower bound) on the true price using a lower bound (an upper bound) by Monte Carlo simulation. A number of effective estimators of the upper and lower bounds with reduced variance are proposed. The results obtained are supported by numerical experiments which look promising.
