Model-free measurement of exchange market pressure

Klaassen, Franc; Jager, Henk - 2006

If there is exchange market pressure (EMP), monetary authorities can use the interest rate and official interventions to offset this depreciation tendency, or they can let the exchange rate change. We introduce a new approach to derive how these three variables should be combined to measure EMP....

A closed-form estimator for the multivariate GARCH(1,1) model

Sbrana, Giacomo; Poloni, Federico - In: Journal of Multivariate Analysis 120 (2013) C, pp. 152-162

We provide a closed-form estimator based on the VARMA representation for the unrestricted multivariate GARCH(1,1) model. We show that the GARCH parameters can be derived analytically, using the autocovariances of the observed data, applying simple linear algebra tools. The resulting estimator is...
