Long memory is found in the conditional volatilities of financial returns measured at daily or higher frequencies, as well as in residual cross-products in bivariate series. We test for long memory in conditional correlations by extending the fractionally integrated GARCH model to include...

heteroskedastic SVAR-GARCH model and propose a bootstrap-based inference procedure on structural impulse responses. We compare the … finite-sample properties of our bootstrap method with those of two competing bootstrap methods via extensive Monte Carlo … simulations. We also present a three-step estimation procedure of the parameters of the SVAR-GARCH model that promises numerical …

This paper employs weighted least squares to examine the risk-return relation by applying high-frequency data from four … returns and expected risk. However, by using quantile regressions, we find that the risk-return relation moves from negative … to positive as the returns’ quantile increases. A positive risk-return relation is valid only in the upper quantiles. The …

This article provides an introduction to methods and challenges underlying application of the bootstrap in econometric … modelling of economic and financial time series. Validity, or asymptotic validity, of the bootstrap is discussed as this is a … key element in deciding whether the bootstrap is applicable in empirical contexts. That is, as detailed here, bootstrap …
