Abstract

Wir untersuchen Übernahmen deutscher Unternehmen zwischen 1985 und 1993 im Hinblick auf ihren Einfluß auf den Marktwert des Käufers. In Erweiterung bisheriger Studien analysieren wir insbesondere, welche Ereignisse den größten Informationsgehalt haben und damit zu den deutlichsten Kursanpassungen führen. Wie frühere Studien dokumentieren wir eine Steigerung des Marktwertes des Käufers bei Erwerb von Mehrheitsbeteiligungen an anderen Unternehmen. Wir zeigen jedoch, daß dies ausschließlich auf Transaktionen in konjunkturstarken Jahren zurückzuführen ist. Weiterhin dokumentieren wir, daß der Zeitpunkt der Kapitalmarktreaktion sehr stark vom Ausmaß der Kontrolle durch das Bundeskartellamt abhängt: Je stärker die Kontrolle, desto umfassender sind die Informationspflichten der beteiligten Unternehmen und desto früher gelangen Informationen über den Zusammenschluß an den Kapitalmarkt.
