Mehr und mehr werden internationale Börsenplätze als elektronisches Handelssystem mit offenem Auftragsbuch gestaltet. Diese Form der Handelsorganisation ersetzt zunehmend die „klassische“ Form des Parketthandels mit zentralem Kursmakler. Sogar die weltweit wichtigste Börse, die New York...

Basierend auf einem strukturellen Modell analysieren die Autoren das Bedeutung informierten Handels (adverse Selektionseffekte) und dessen Auswirkung auf die Liquiditätsqualität in Xetra, dem elektronischen Handelssystem der Deutschen Börse . Die ökonometrische Analyse basiert auf einem...

Kursänderungen auf Aktienmärkten können informationsinduziert durch neu zu verarbeitende Informationen oder liquiditätsinduziert durch kurzfristige Angebots- bzw. Nachfrageüberhänge auftreten. Diese zwei so unterschiedlich verursachten Kursreaktionen sind in empirischen Untersuchungen nur...

Trading activity surges associated with latency arbitrage are costly, as they lead to both lower liquidity and inefficient investments in order processing capacity that remains idle 90% of the time. A congestion message fee on liquidity-taking orders alleviates both concerns. The fee surges...
