Scientific Gals
The aim of this project is to propose some generalizations/modifications of structural models
and numerical methods previously presented in the literature for the risk-neutral pricing of financial
instruments in emission markets. For the structural models proposed, our goals are to derive a
forward-backward stochastic differential equation (FBSDE)
for the price process of the emissions certificates and solve numerically the associated nonlinear
partial differential equations for the certificate price and for the prices of financial derivatives
in the emissions market.
The basic element of the structural model is an exogenously specified stochastic process modelling the
electricity demand and allowances certificates are considered as derivatives depending on the demand process and cumulative emissions. The generalizations/modifications
of the structural model which we will study are of the following type:
- Consider more general forms for the demand process, allowing for feedback effects between the
price and the demand process or considering that the drift depends on time explicitly;
- Consider different functional forms for the bid and emission stacks.
In order to solve the PDEs for the pricing problem we will propose and study appropriate efficient numerical methods.
Scientific Objectives
I. Structural Models and FBSDEs
Our first goal is to study the standard structural model for the risk neutral pricing of emission
certificates and propose modifications to this model considering the demand process of electricity,
which is the basic underlying stochastic process affecting the emissions certificate
and the functional forms of the bid and emissions stacks
(which model the cumulative emissions and the interaction between the electricity and emission markets).
In particular, we modify the basic structural model considering the following cases:
- Modify the demand process in order to consider feedback effects between the price
and the demand process and/or that the drift depends on time explicitly.
- Consider different concrete stochastic differential equations for the modelling
of the demand process (possibly including different diffusion processes or jump-diffusion processes)
- Consider different functional forms for the bid and the emissions stacks and
study what is the effect on the pricing of emission certificates.
For the modified structural models, we intend to derive the corresponding
forward-backward stochastic differential equation (FBSDE) that represents the price of the
emission certificates and study the problem of existence/uniqueness of solution for this equation
and explore the basic properties of the solution.
II. PDEs for Certificate Pricing and Derivatives Pricing
The risk-neutral price of the allowance certificate can be represented as the solution of a FBSDE.
By using Itô's stochastic calculus and Itô's formula, the price of the certificate can also be
represented as the solution of an appropriate nonlinear partial differential equation (PDE).
In the case of our structural modified models, we want to study two particular problems
related with these PDEs:
- Study the properties of the solution of the nonlinear PDE in some asymptotic cases (e.g. near expiry)
- Propose efficient numerical methods for solving the nonlinear PDE.
Examples of methods that can be tested are alternating direction finite difference schemes or semi-Lagrangian schemes,
among others.
- Study the problem of the pricing of financial derivatives and options written on
the allowance certificate by solving an appropriate PDE.
The industrial partner of this project, the GEFA bank, has
the main office located in Wuppertal and a branch in Bratislava.
This setting will offer the unique opportunity for mutual exchange
between academia and industry, transfer of knowledge and also with
the option for jointly supervised theses.
