The course gives an elementary introduction to probability theory and stochastic processes for nance, by focusing on discrete probability spaces and their modeling applications. The lecture starts from the setting of a simple binomial pricing model to introduce key probability concepts that are useful for applications. Its covers the concepts of random variables, stochastic independence, conditional and unconditional expectations, and martingale processes, with some examples of applications to the pricing of derivatives in arbitrage-free markets. Finally, the idea of a state price and the relation to measure changes is explained, together with some pricing examples in the context of a Capital Asset Pricing Model.
There will be a open book, written exam.
