Sowohl die Diversifikation als auch die Fokussierung von Unternehmensaktivitäten werden häufig mit der Maximierung des Unternehmenswertes begründet. Wir untersuchen die Auswirkungen auf den Aktienkurs für 184 Akquisitionen sowie 139 Desinvestitionen deutscher Konzerne im Zeitraum von...

This paper analyzes capital market reactions to international bank M&A. We investigate combined stock return patterns of targets, bidders, and their peers upon takeover announcement, and closing or withdrawal. We distinguish five common M&A hypotheses and relate characteristic and mutually...

Due to judicial decisions the stock market prices are deemed to be the lower value limit in determining the compensations within structural measures according to German stock corporation law (e.g. squeeze-out of minority stockholders). By applying other valuation methods, in particular the...

This paper investigates the impact of the 2001 tax reform in Germany on dividend announcement returns. With this major tax reform, the full imputation system was replaced by the half-income system, which had a significant impact on the relative taxation of dividends and capital gains for most...

Do pre-offer target stock price runups increase bidder takeover costs? We present model-based tests of this issue assuming runups are caused by signals that inform investors about potential takeover synergies. Rational deal anticipation implies a relation between target runups and markups (offer...

Recent research questions the existence of a conglomerate discount. This study addresses two of the most important explanations for the conglomerate discount and finds evidence in support of an economically and statistically significant discount. The first explanation is that the risk-reducing...
