This paper delineates the simultaneous impact of non-anticipated information on first and second moments of the intraday price process by including appropriate variables accounting for the news flow into both the mean and the variance function. This allows us to differentiate between the...

Ein Berater erfüllt einerseits die Rolle des Wissensvermittlers, andererseits kann er die Funktion übernehmen, bestehende Probleme und geplante Maßnahmen verschiedenen Interessensgruppen gegenüber zu legitimeren. Dieser Artikel zeigt empirische Evidenz für die Rolle des IT-Beraters auf...

We analyze contributions of different markets to price discovery on traded inflation expectations and how it changed during the financial crisis. The quicker information is processed on one market and the less one market is disrupted by the financial crisis the more valuable is its information...
