F71DT Discrete-Time Finance

Aims:

To introduce, in a discrete time setting, the basic probabilistic ideas and results needed for the conceptual understanding of the theory of stochastic process and its application to financial derivative pricing.

Summary:

  • Introduction to background probability theory.
  • Conditional expectation.
  • Discrete-time martingales, sub- and supermartingales.
  • Stopping Times, Optional Stopping Theorem, Snell Envelopes.
  • Arbitrage and martingales, risk neutral measures.
  • Complete markets and discrete option pricing.
  • The binary tree model of Cox, Ross and Rubinstein for European and American option pricing.
  • Dividends in the binomial models.
