# DYNAMIC ASSET PRICING THEORY - 2021/2

Module code: MAT3049

## Module Overview

This module is an introduction to modern asset pricing theory.

The module begins with elements of stochastic calculus (specifically, the Ito calculus) sufficient to follow basic ideas in asset pricing theory that underlies modern investment banking.

After the introduction to background mathematics, the module develops the theory of asset pricing in an axiomatic way so as to avoid irrelevant digression and to get straight to the main idea of “pricing kernel” that lies at the heart of pricing financial contracts.

As a simple example, the Black-Scholes option pricing formula is derived.

The module then develops interest rate theory and introduces, as an example, the Vasicek model, but presented in the modern language using pricing kernel.

The module concludes with a brief application to modelling cryptocurrency economy.

## Assessment Strategy

The assessment strategy is designed to provide students with the opportunity to demonstrate

• The ability to manipulate stochastic processes;

• The basic knowledge of the subject, such as important definitions and concepts;

• The ability to combine theory with a model to arrive at prices of financial products.

Thus, the summative assessment for this module consists of:

• One two-hour examination at the end of Semester 1, worth 80% of the module mark;

• One in-semester test, worth 20% of the module mark.

Formative assessment and feedback:

There is feedback from unassessed coursework assignments. Verbal feedback is provided by the lecturer during the lectures (e.g., when exercises are worked out), and also in office hours.

## Module aims

- To equip students with the understanding of basic stochastic calculus sufficient to navigate their way through asset pricing theory.
- To equip candidates with the understanding of the modern approach to asset pricing using pricing kernel.
- To equip candidates with the understanding of interest rate modelling.

## Methods of Teaching / Learning

The learning and teaching strategy is designed to:

• Offer a short introduction to stochastic calculus sufficient to perform stochastic differentiation / integration.

• Introduce the modern theory of asset pricing in the most direct and concise manner that is applicable to manage risks associated with a broad range of financial products.

• Demonstrate how well-known financial models like Black-Scholes and Vasicek can be worked out with little superfluous knowledge (such as risk-neutral valuation).

The learning and teaching methods include:

• 3 hour lectures per week, for 11 weeks. Typeset notes, containing exercises and examples, will be provided along the way.

Indicated Lecture Hours (which may also include seminars, tutorials, workshops and other contact time) are approximate and may include in-class tests where one or more of these are an assessment on the module. In-class tests are scheduled/organised separately to taught content and will be published on to student personal timetables, where they apply to taken modules, as soon as they are finalised by central administration. This will usually be after the initial publication of the teaching timetable for the relevant semester.
