The paper estimates the long-run elasticities of import demand in Jordan over the period 1980-2004. The Engle-Granger test of co-integration, fails to find favor of a long-run relationship among variables associated with an import demand. Furthermore, the recently prescribed Stock-Watson Dynamic...

We propose a least squares regression framework for the estimation of the realized covariation matrix using high frequency data. The new estimator is robust to market microstructure noise (MMS) and non-synchronous trading. Comprehensive simulation and empirical analysis show that our estimator...

The paper proposes a new robust estimator for GARCH-type models: the nonlinear iterative least squares (NL-ILS). This estimator is especially useful on specifications where errors have some degree of dependence over time (weak-GARCH) or when the conditional variance is misspecified. I illustrate...
