The continuous behavior of the numeraire portfolio under small changes in information structure, probabilistic views and investment constraints
continuous behavior numeraire portfolio small changes information structure probabilistic views investment constraints
2010/12/17
The numeraire portfolio in a financial market is the unique positive wealth process that makes all other nonnegative wealth processes, when deflated by it, supermartingales. The numeraire portfolio de...
GARCH modelling in continuous time for irregularly spaced time series data
GARCH modelling continuous time irregularly spaced time series data
2010/12/17
The discrete-time GARCH methodology which has had such a profound influence on the modelling of heteroscedasticity in time series is intuitively well motivated in capturing many `stylized facts' conce...

Log-Normal continuous cascades aggregation properties estimation Application financial time-series
2010/12/17
Log-normal continuous random cascades form a class of multifractal processes that has already been successfully used in various fields. Several statistical issues related to this model are studied. W...
Constructing the Optimal Solutions to the Undiscounted Continuous-Time Infinite Horizon Optimization Problems
Constructing Optimal Solutions Undiscounted Continuous-Time Infinite Horizon Optimization Problems
2010/12/17
We aim to construct the optimal solutions to the undiscounted continuous-time infinite horizon optimization problems, the objective functionals of which may be unbounded. We identify the condition un...
