On non-existence of a one factor interest rate model for volatility averaged generalized Fong-Vasicek term structures

open access: yes, 2008
The purpose of this paper is to study the generalized Fong--Vasicek two-factor interest rate model with stochastic volatility. In this model the dispersion of the stochastic short rate (square of volatility) is assumed to be stochastic as well and it ...

Hierarchical Regularizers for Reverse Unrestricted Mixed Data Sampling Regressions

open access: yesJournal of Forecasting, EarlyView.
Abstract Reverse Unrestricted MIxed DAta Sampling (RU‐MIDAS) regressions are used to model high‐frequency responses by means of low‐frequency variables. However, due to the periodic structure of RU‐MIDAS regressions, the dimensionality grows quickly if the frequency mismatch between the high‐ and low‐frequency variables is large.

Fundamentals Models Versus Random Walk: Evidence From an Emerging Economy

open access: yesJournal of Forecasting, EarlyView.
ABSTRACT We analyze the predictive power of fundamentals versus random walk models for horizons from 1 to 24 months in an emerging market. Specifically, we investigate what fundamentals models outperform random walk during periods of appreciation and depreciation of the exchange rate.

A New Scheme for Static Hedging of European Derivatives under Stochastic Volatility Models ( Revised in June 2008, Published in "Journal of Futures Markets", Vol.29-5, 397-413, 2009. ) [PDF]

open access: yes
This paper proposes a new scheme for static hedging of European path-independent derivatives under stochastic volatility models. First, we show that pricing European path-independent derivatives under stochastic volatility models is transformed to ...

Pricing VXX Options With Observable Volatility Dynamics From High‐Frequency VIX Index

open access: yesJournal of Futures Markets, EarlyView.
ABSTRACT This paper develops a discrete‐time joint analytical framework for pricing volatility index (VIX) and VXX options consistently. We show that our framework is more flexible than continuous‐time VXX models as it allows the information contained in the high‐frequency VIX index to be incorporated for the joint pricing of VIX and VXX options, and ...
