Industrial production is analysed for three countries. A GARCH framework is employed to model the conditional variances of the cycles, which are found to react asymmetrically to shocks of opposite sign; one of the three cases exhibits long-memory features. The ability of GARCH models at...

The paper investigates whether the impact of selected news - scheduled and un-scheduled - affects only the current conditional variance of financial prices or, by bringing new information to the market, induces also a revision of the implied variance, i.e. the variance expected to prevail over...
