A num¡¦eraire is the unit of account in which other assets are denominated.
One usually takes the num¡¦eraire to be the currency of a country.
In some applications one must change the num¡¦eraire due to the finance considerations.
And sometimes it is convenient to change the num¡¦eraire because
of modeling considerations. A model can be complicated or simple, depending
on the choice of thenum¡¦eraire for the method.
When change the num¡¦eraire, denominating the asset in some other unit of account,
it is no longer a martingale under ˜P . When we change the num¡¦eraire,
we need to also change the risk-neutral measure in order to maintain risk
neutrality.
The details and some applications of this idea developed in this thesis.
