SUMMER PROJECTS 2009
A PROVISIONAL list of projects for summer 2009 is given below. This
list is not yet complete. It will be updated on a regular
basis.
I will soon distribute a form with, hopefully, a full list of
projects
and supervisors. You should list your top 6 preferences on this.
It is likely that demand for some projects will outstrip supply,
so not all students will get their first choices. Placements
will be given careful consideration after the preliminary
results of April/May exams are known to the examiners and will be
restricted to those students who have performed well in exams to date.
Once projects have been allocated please contact your supervisor
as soon as possible to discuss your timetable for the summer. In many
cases lecturers will be taking their annual holiday during the
period of your project. It is important that you discuss details
with your supervisor to make sure that there are no prolonged periods
without the possibility of a meeting. Some lecturers have already
specified
dates when they will be away and these are detailed below.
Some students may have organised projects/placements themselves
in discussion with me. Please let me have final details as soon
as possible so that this can be fitted into the overall scheme.

- Modeling financial market prices using the ARCH and GARCH
models
Supervisor: Janusz Brzeszczynski, HWU School of Management and Languages
Number of students: 2
Periods of absence:
Summary: This project involves estimation of various types of ARCH
models. Empirical applications can be based on the data set composed of
the major international stock market indices or the data from the
foreign exchange market. Different data frequency will be used. As the
by-product, the obtained results may be useful for verifying the
hypothesis about the financial markets efficiency.
Computing component: over 75%.
- Effects of Microfinance on Firm Performance: Evidence from
Romania
Supervisor: David Brown, HWU School of Management and Languages
Number of students: 1
Periods of absence:
Summary:
USAID conducted a microfinance
program in Romania in the late 1990’s and early 2000’s. Did the
firms receiving the loans achieve performance benefits, or was the
money wasted? The project will compare the performance of loan
recipients before and after receiving the loan to that of otherwise
similar firms not receiving loans.
Computing component: Intensive
computing component, working with a large dataset. The student needs
to have access to the STATA statistical software package.
- Autocorrelated Conditional Duration (ACD) of Shares at the
London Stock Exchange
Supervisor: Boulis Ibrahim, HWU School of Management and Languages
Number of students: 2
Periods
of absence: 5 weeks annual leave the
starting date of which may vary but provisionally from 28 June to end
of July.
Summary: This project will deal with the modeling of time between
trades on some shares that trade at the London Stock Exchange. The
modeling will use ACD models which are time varying models of positive
variables. They are related to statistical treatment of survival
analysis.
Computing component: The candidate(s) should expect extensive computing
work on a substantial database of high frequency trade by trade data.
This requires detailed knowledge of SQL (Standard Query Language) or
Microsoft Access (In the case of Access, however, the candidate must be
self equipped with a computer that has 3 or 4 GB RAM and 200GB or so of
spare disk capacity).
- Modeling Consumption Asset Pricing Models in Developed and
Emerging Stock Markets
Supervisor: Moh Sherif, HWU School of Management and Languages
Number of students: 2
Periods of absence:
Summary: To address the empirical failure of the CCAPM, considerable
attention has been devoted to market frictions as well as alternative
utility specifications. Both of these strands can claim some success,
but they have until now been considered separately. The focus of this
project is therefore to consider both in the same study.
First considered is whether the value of relative risk aversion can be
changed by using parametric and non parametric tests and different
utility functions. Whereas the power utility model introduces a basic
learning framework of the relation between consumption and asset
returns, there is general consensus that there is evidence against the
model as an asset pricing tool and for its ability to resolve the
equity premium puzzle. Within the context of representation of agent
models, various studies have attempted to introduce more general
preferences. In this project, tests are made of the traditional CAPM,
CCAPM, H-CCAPM, Epstein and Zin (1989, 1991) model, and external habit
formation specification using GMM.
Further we investigate the pricing errors of asset pricing models by
estimating the vertical and minimum distances to the Hansen-Jagannathan
bound (Hansen and Jagannathan (1991, 1997)).
Different utility specifications are found to have considerably less
impact than the introduction of market frictions, which in general has
a significant impact, and the model is often accepted. Therefore, in
the second part of this project we investigate the impact of a
combination of utility specifications and market frictions on the
performance of asset pricing models.
Computing component: Empirical applications will be based on the data
set composed of the major developed and emerging international stock
market indices.

- Mean-reverting stochastic
volatility models and equivalent martingale measures
Supervisor: Sotirios Sabanis, UoE School of Mathematics
Number of students: 1-2
Periods of absence:
Summary: This project is an extension of the option offered under the
same title. Recall that empirical evidence on underlying asset prices
strongly suggest that asset price volatility is stochastic. Thus,
alternative option pricing methods were considered in order to
eliminate the biases in the Black-Scholes model. A popular class of
models is known as stochastic volatility models, where volatility is
assumed to be an Ito process. As a result, a contingent claim can not
be duplicated by a self- financing portfolio consisting of a number of
(underlying asset) shares and a (zero-coupon) bond due to the
additional source of uncertainty (i.e., the Brownian motion that drives
the volatility process). Therefore, the market is not complete (in the
sense of Harrison and Pliska) and the existence of a unique equivalent
martingale measure (EMM) does not hold. However, the no-arbitrage
assumption insures that there exists a EMM, in fact there exist many
equivalent martingale measures. As a consequence, different authors set
different criteria in order to choose the "appropriate" EMM and price
options in continuous-time.
The aim of this project is to price European options using different
EMMs.

- Local volatility function
models
Supervisor: Sotirios Sabanis, UoE School of Mathematics
Number of students: 1-2
Periods of absence:
Summary: The aim of this project is to price index derivatives using
historical data from the International Financial Futures and Options
Exchange (LIFFE) in London. Under the benchmark approach of Heath &
Platen, the pricing and hedging of derivatives does not require the
existence of an equivalent risk neutral martingale measure. Fair prices
for index derivatives when expressed in units of the index are
martingales under the real world probability measure.

- Approximation of American put
options by options with random expiry
SUPERVISOR: Terence Chan, HWU School of Mathematical and Computer
Sciences
Number of students: 4
Periods of absence:
Summary: One of the main difficulties in pricing an American put with
finite expiry is the computation of the optimal exercise level - this
depends on the remaining life of the option and can only be computed
numerically. In the case of American puts with infinite expiry
(perpetual puts), the problem is much easier because the optimal
exercise barrier is constant. An idea (due to Carr) is to consider a
sequence of American puts with random exponentially distributed
expiries. The memoryless property of the exponential distribution
reduces the problem to that of a perpetual put. In this project,
students will study the theory behind this and apply it compute the
price of American puts where the underlying asset is modelled as the
exponential of a simple Levy process (Brownian motion or BM + Poisson).
This project is suitable for a group of up to 4 students working on the
same theoretical aspects and applying them to slightly different
models. There is a large practical computational component requiring
the writing of suitable computer code (e.g. in Matlab). The balance of
theoretical and practical is approx. 50/50.
- Continuous Time Stochastic
Control
SUPERVISOR: Tim Johnson, HWU School of Mathematical and
Computer
Sciences
Number of students: 4
Periods of absence:
Summary: Stochastic control is one of the most important tools in
financial mathematics. In fact the Black-Scholes-Merton model,
along with any dynamic portfolio management problem, can be viewed as
the solution to a particular problem in stochastic control.
The student will be expected to do some research into the ideas
underpinning the theory of stochastic control and then investigate how
those theories are applied in finance. The student could take a
number of paths, for example they could look at some contemporary
theoretical issues or investigate the numerical solution of problems.
Students will work as a group in developing their understanding of
stochastic control and then work on specific issues individually.
Students will be assessed on the clarity and depth of their
dissertation if they choose to undertake a survey of theory. If
students address the numerical solution of a problem, they will be
assessed on the novelty of the approach or the problem being
solved.
- Extensions to the Standard
Vasicek Model of Portfolio Credit Risk
SUPERVISOR: Alex McNeil, HWU School of Mathematical and Computer
Sciences
Number of students: 4
Periods of absence:
Summary: The Vasicek single factor model of portfolio credit risk is
widely used in industry and has been influential in the development of
the Basel II regulatory capital formula. Vasicek's model builds on
Merton's idea that firm default is caused when a critical variable,
often interpreted as a measure of asset value, lies below a critical
threshold, often interpreted as a measure of short-term liabilities, at
some designated time horizon. The Vasicek model extends Merton to a
portfolio model by assuming that the critical variables for all
obligors follow a one-factor Gaussian model, giving rise to a Gaussian
copula dependence structure for joint defaults. One-factor portfolio
versions of industrial models like KMV and CreditMetrics essentially
follow the Vasicek construction.
In this project it will be of interest to investigate the effects of
changing features of Vasicek's model and adding new features. The
project is partly prompted by interest from Barrie & Hibbert who
are employing a Vasicek-style model to capture credit dependence in
their economic scenario generator (ESG).
Computing component: ca 40%
- American options: Early exercise
and pricing in incomplete markets
SUPERVISOR: Mark Owen, HWU School of Mathematical and Computer
Sciences
Number of students: 4
Periods of absence:
Summary: In a complete market, where both the buyer and seller of an
American option may completely hedge their position by trading the
underlying security, the determination of the early exercise boundary
has been thorougly studied; the literature goes back as far as work by
McKean (1965) and Merton (1973). In many cases there are no exact
formulae for the early exercise boundary, although a numerical
determination of the boundary is fairly straightfoward. The notable
exceptions to the lack of exact solutions are the cases of perpetual
options (where the early exercise boundary is time-invariant), and the
case of a call option on a non-dividend-paying asset (in which case
early exercise is never optimal).
This project will allow students to study the optimal exercise (and the
pricing) of American options. The project will begin with a literature
survey, and implementation of numerical methods to determine the early
exercise boundary for both classical and perpetual options. Following
this, students will consider some methods for determining the optimal
exercise policy for the buyer and the seller in a incomplete markets
(again, both theoretically and numerically). There is scope for
investigation of separate sources of incompleteness.

- Utility Maximisation Problems in
Incomplete Markets
SUPERVISOR: Anke Wiese, HWU School of Mathematical and Computer Sciences
Number of students: 4
Periods of absence:
Summary: In this project, we will investigate some key approaches for
solving optimal portfolio problems in incomplete markets by maximising
the expected utility of an individual investor. We will first review
some of the existing approaches and further investigate concrete
examples of financial derivative for which we compute values
(prices) and hedging strategies analytially and numerically.
Possible examples that can be investigated include
- volatility derivatives in stochastic volatility models
- insurance derivatives as they arise when the combination of insurance
and financial risk is considered.
The project will include the numerical implementation and investigation
of resulting option prices.
