The early-exercise opportunity of an American option leads to entirely new questions. While the buyer of an American option is interested in optimal exercise, the seller wants to find reasonable bid and ask prices. In this work, problems from both perspectives are discussed. At the beginning, the mathematical necessities from stochastics and financial mathematics are provided. Afterwards, the problem of optimal exercise is explained and moreover, the hedging theory from a seller's perspective is presented. The main part of this thesis concerns the pricing of American options. In this context, theoretical approaches in complete and incomplete markets are presented. Motivated by a paper of Mark Broadie and Paul Glasserman, a pricing algorithm based on Monte Carlo simulation is presented and implemented in R. Finally, this algorithm is applied to some examples, where a stock of the DAX 30 is used as an underlying asset.
