In a previous paper, we studied the ergodic properties of an Euler scheme of a stochastic differential equation with a Gaussian additive noise in order to approximate the stationary regime of such an equation. We now consider the case of multiplicative noise when the Gaussian process is a...

In this paper a new bivariate distribution called Marshall–Olkin–Morgenstern-bivariate-Weibull distribution is introduced and studied. Two different models of minification processes with the above bivariate distribution as stationary marginal distribution are developed. It is shown that the...

We propose methods for testing hypotheses of non-causality at various horizons, as defined in Dufour and Renault (1998, Econometrica). We study in detail the case of VAR models and we propose linear methods based on running vector autoregressions at different horizons. While the hypotheses...

This paper computes Malawi's equilibrium real exchange rate as a function of its fundamentals as derived from economic theory. It finds evidence in favor of the equilibrium approach to exchange rate determination, with several variables (particularly government consumption and real per capita...

This paper studies a class of estimators for the variance parameter of a stationary stochastic process. The estimators are based on L_p norms of standardized time series, and they generalize previously studied estimators due to Schruben. We show that the new estimators have some desirable...

In analyzing the output process generated by a steady-state simulation, we often seek to estimate the expected value of the output. The sample mean based on a finite sample of size n is usually the estimator of choice for the steady-state mean; and a measure of the sample mean's precision is the...

This paper extends the long-run growth model of Esfahani et al. (2009) to a labor exporting country that receives large inflows of external income?the sum of remittances, FDI and general government transfers?from major oil-exporting economies. The theoretical model predicts real oil prices to be...
