We develop a discrete-time affine stochastic volatility model with time-varying conditional skewness (SVS). Importantly, we disentangle the dynamics of conditional volatility and conditional skewness in a coherent way. Our approach allows current asset returns to be asymmetric conditional on...

Using positive semidefinite supOU (superposition of Ornstein-Uhlenbeck type) processes to describe the volatility, we introduce a multivariate stochastic volatility model for financial data which is capable of modelling long range dependence effects. The finiteness of moments and the second...

This paper addresses whether the spot exchange rates display long swings and whether these swings are persistent. The null from the naïve random walk theory is that they do not: if they would be unit roots with positive drifts they would converge to infinity. However, if they would be driftless...

This paper studies dynamic relation, namely, two currencies of Korean won and Japanese yen, before and after the East Asian financial crisis of the late 1990s. We conjecture that there exists a long-run relation between won and yen, which is characterized by a band-reverting-type dynamic...

In this paper, I have investigated the out of sample forecast performance for a case study on the determination of the nominal exchange rate for USD vis-à-vis IN¬R under VEC, VAR (in first difference) and Bayesian VAR specification with the help of set of economic theories. The forecast...

We address the general issue of econometric specifications of dynamic asset pricing models, which cover the modern literature on conditionally heteroskedastic factor models as well as equilibrium-based asset pricing models with an intertemporal specification of preferences and market fundamentals.
