Central wage bargaining and local wage flexibility : evidence from the entire wage distribution
(1998)
We argue that in labor markets with central wage bargaining wage flexibility varies systematically across the wage distribution: local wage flexibility is more relevant for the upper part of the wage distribution, and flexibility of wages negotiated under central wage bargaining affects the lower part of the wage distribution. Using a random sample of German social-security accounts, we estimate wage flexibility across the wage distribution by means of quantile regressions. The results support our hypothesis, as employees with low wages have significantly lower local wage flexibility than high wage employees. This effect is particularly relevant for the lower educational groups. On the other hand, employees with low wages tend to have a higher wage flexibility with respect to national unemployment.
This paper shows that abnormal stock price returns around open market repurchase announcements are about four times higher in Germany than in the US (12% versus 3%). We hypothesize that this observation can be explained by country differences in repurchase regulation. Our empirical evidence indicates that German managers primarily buy back shares to signal an undervaluation of their firm. We demonstrate that the stringent repurchase process prescribed by German law attributes a higher credibility to such a signal than lax US regulations and thereby corroborate our hypothesis.
Im Rahmen einer Ereignisstudie am deutschen Kapitalmarkt wird untersucht, ob Adhoc- Mitteilungen korrekt eingesetzt werden. Die Ergebnisse belegen, daß Nemax-50-Unternehmen die Veröffentlichung potentiell positiver Meldungsinhalte bevorzugen und die Bekanntmachung negativer Mitteilungen verzögern. Außerdem veröffentlichen Nemax-50-Werte in positiven Marktphasen besonders viele Mitteilungen und einen besonders hohen Anteil an positiven Meldungsinhalten, um von der positiven Stimmung der Marktteilnehmer zu profitieren. Dax-30-Werte verhalten sich dagegen regelgerecht. Die Befunde belegen die Notwendigkeit einer stärkeren Überwachung des Veröffentlichungsverhaltens der Emittenten, die in 2002 am Neuen Markt gelistet waren.
