Objectives

On the completion of this unit students will gain an understanding of the methods of modern probability and random processes, and develop skills for modelling of random systems. Students will be able to apply this knowledge and skills in the context of financial and insurance modelling. Specifically, on the completion of this unit, students will:

  • understand the modern approach to evaluation of uncertain future payoffs;
  • understand the concepts of arbitrage and fair games and their relevance to finance and insurance;
  • understand the concept of conditional expectation, martingales, and stopping times, as well as the Optional Stopping Theorem;
  • understand models of random processes such as Random Walk, Brownian Motion and Diffusions, and Stochastic Differential equations;
  • be able to use Ito's formula, and basic stochastic calculus, and be able to solve some stochastic differential equations by using rules of stochastic calculus;
  • know Fundamental theorems of asset pricing, being able to apply them to the Binomial and Black-Scholes models, as well as models for bonds and options on bonds;
  • be able to formulate discrete time Risk Model in Insurance and use the Optional Stopping Theorem to control probabilities of ruin;
  • be able to simulate stochastic processes and solutions of stochastic differential equations, and obtain prices by simulations.
