The tail of the stationary distribution of a random coefficient AR(q) model
We investigate a stationary random coefficient autoregressive process. Using renewal type arguments tailor-made for such processes, we show that the stationary distribution has a power-law tail.

Wavelet-Based Prediction for Governance, Diversification and Value Creation Variables [PDF]
We study the possibility of completing data bases of a sample of governance, diversification and value creation variables by providing a well adapted method to reconstruct the missing parts in order to obtain a complete sample to be applied for testing ...

Cross sectional efficient estimation of stochastic volatility short rate models [PDF]
We consider the problem of estimation of term structure of interest rates. Filtering theory approach is very natural here with the underlying setup being non-linear and non-Gaussian. Earlier works make use of Extended Kalman Filter (EKF).

ANOVA for diffusions and It\^{o} processes
It\^{o} processes are the most common form of continuous semimartingales, and include diffusion processes. This paper is concerned with the nonparametric regression relationship between two such It\^{o} processes.

Break detection in the covariance structure of multivariate time series models
In this paper, we introduce an asymptotic test procedure to assess the stability of volatilities and cross-volatilites of linear and nonlinear multivariate time series models.

This paper studies the quasi-maximum-likelihood estimator (QMLE) in a general conditionally heteroscedastic time series model of multiplicative form $X_t=\sigma_tZ_t$, where the unobservable volatility $\sigma_t$ is a parametric function of $(X_{t-1},...,

The role of exchange rate dynamics in Bulgaria and Romania in the process of economic transition [PDF]
Our contribution focuses on the role of the exchange rate changes in Bulgaria and Romania during the transition process toward a market economy. We are interested in the degree of exchange rate pass-through to the domestic inflation in these countries ...

The impact of exchange rate changes on inflation in the V4 countries in the process of economic transition [PDF]
Our contribution focuses on the role of the exchange rate changes in the V4 countries during the transition process towards a market economy. Regarding the variety of exchange rate regimes implemented in the V4 countries at the start of the economic ...
