The numeraire property and long-term growth optimality for drawdown-constrained investments
numeraire property long-term growth optimality drawdown-constrained investments
2012/9/14
We consider the portfolio choice problem for an investor interested in long-run growth optimality while facing drawdown constraints in a general continuous semimartingale model. The paper introduces t...
Comparing the performance of FA, DFA and DMA using different synthetic long-range correlated time series
DFA and DMA synthetic long-range time series
2012/9/17
Notwithstanding the signi cant e orts to develop estimators of long-range correlations (LRC) and to compare their performance, no clear consensus exists on what is the best method and under which cond...

The Long Neglected Critically Leveraged Portfolio
2012/9/14
We show that the ecient frontier for a portfolio in which short positions precisely o set the long ones is composed of a pair of straight lines through the origin of the risk-return plane. This uniqu...

2012/9/14
We examine the scaling regime for the detrended fluctuation analysis (DFA) -the most popular method used to detect the presence of long memory in data and
the fractal structure of time series. First,...

We extend Kirman's model by introducing variable event time scale. The proposed
exi-
ble time scale is equivalent to the variable trading activity observed in nancial markets.

On the Persistence of Real Interest Rates: New Evidence from Long-Horizon Data
Real interest rate CCAPM local-to-unity half-life
2010/9/7
Since the paper of Rose (1988), a large literature has emerged on testing the stationarity of real interest rates using a variety of econometric procedures. In this study, we emphasize that the low po...
