In the present paper we provide an analytical solution for pricing discrete barrier options in the Black-Scholes framework. We reduce the valuation problem to a Wiener-Hopf equation that can be solved analytically. We are able to give explicit expressions for the Greeks of the contract. The...

We consider the problem of stochastic comparison of general Garch-like processes, for different parameters and different distributions of the innovations. We identify several stochastic orders that are propagated from the innovations to the Garch process itself, and discuss their...

Recently several authors focused their attention on Acceptability Indexes (AI) and their applications in Finance. The AI notion turns out to be quite flexible and several applications in different directions have been proposed. In particular, in a paper by A. Cerny and D. Madan illiquid markets...
