Outcomes

On completion of this unit students will be able to:

  1. Appreciate the modern approach to evaluation of uncertain future payoffs;

  1. Describe the concepts of arbitrage and fair games and their relevance to finance and insurance;

  1. Understand conditional expectation, martingales, and stopping times, as well as the Optional Stopping Theorem;

  1. Interpret models of random processes such as random walk, Brownian motion and diffusion, and stochastic differential equations;

  1. Use Ito's formula and basic stochastic calculus to solve some stochastic differential equations;

  1. Apply the Fundamental theorems of asset pricing to the Binomial and Black-Scholes models, as well as models for bonds and options on bonds;

  1. Formulate discrete time Risk Model in Insurance and use the Optional Stopping Theorem to control probabilities of ruin;

  1. Simulate stochastic processes and solutions of stochastic differential equations, and obtain prices by simulations.
