Example text

Note that the second item in the definition implies that Brownian motion is a Markov process. Moreover, Brownian motion is the basic example of a Lévy process (see Chapter 5). In the above, we have defined Brownian motion without reference to a filtration. In what follows, unless otherwise specified, we will always work with the natural filtration F = FW = {Ft , 0 t T } of W . We have that Brownian motion is adapted with respect to this filtration and that increments Wt+s − Wt are independent of Ft .

1) that a similar simplification to one term can be made. Therefore, the more realistic market models, based on a non-Brownian and non-Poissonian Lévy process, will lead to incomplete market models. Paul Lévy (1886–1971) The name Lévy process refers to one of the greatest mathematicians of the 20th century: Paul Lévy. Paul Lévy was born in Paris in 1886. He studied at the École Polytechnique, obtained a doctoral degree in mathematics from the University of Paris and became professor at the École Polytechnique in 1913.

Continuous payment of a dividend yield at rate q means that our stock is following a process of the form, St = exp(−qt)S¯t , where S¯ describes the stock price’s behaviour, not taking dividends into account. e. dividends plus capital gains. The payment of dividends causes the growth of the stock price to be less than it would otherwise be by an amount q. In other words, if, with a continuous dividend yield of q, the stock price grows from S0 to ST at time T , then in the absence of dividends it would grow from S0 to exp(qt)ST .
