We give a new way to price American options, using Samuelson´s formula. We first obtain the option price corresponding to a European option at time t, weighting it by the probability that the underlying asset takes the value S at time t. This factor is given by the solution of the Fokker-Planck...

The pricing of commodity derivatives requires that the underlying asset be modelled with mean reversion and high volatility. We develop closed formulas to price the spot of the commodity, its future, and to price a call option on the spot and on the commodity future, in the real world and under...

The Black-Scholes valuation model for European options is widely used in the stock markets due to its easy implementation. However, the model is not accurate for different assets whose dynamics do not follow those of a lognormal distribution, so it is necessary to investigate new distributions...
