Abstract
Der vorliegende Beitrag untersucht, weshalb private equity als eine spezifische institutionelle Form des Ausreichens von Eigenkapital die Bedeutung erlangt hat, die es aktuell genießt. Er zeigt, dass die Rolle des Eigenkapitals zunächst aus der Systematik der Ökonomie im Rahmen der Innovationstheorie, der Transaktionskostentheorie und der Risikotheorie erklärt werden kann: Private Equity ist eine spezifische Form der Ausgestaltung der Eigenkapitalversorgung, um für Unternehmen in risikobehafteten Märkten die Transaktionskosten effizient zu senken. Darüber hinaus spielt es für die Glaubhaftigkeit des Marktauftritts von Anbietern eine Rolle. Durch spezifische Unvollkommenheiten der Märkte und vor allem auch durch steuerliche Ausgestaltungen, die unter heutigen Bedingungen als nicht effizient angesehen werden dürften, hat sich die wirtschaftliche Bedeutung der Private Equity-Eigenkapitalausreichung beachtlich vergrößert. Damit wächst auch die Notwendigkeit, Unternehmen im Sinne einer wertorientierten Steuerung zu bewerten. Seit dem Sommer 2007 hat sich der „Hype“ abgeflacht, weshalb in einer abschließenden Würdigung die Zukunftsaussichten von Private Equity betrachtet werden.

Rating Agency Actions and the Pricing of Debt and Equity of European Banks: What Can we Infer About Private Sector Monitoring of Bank Soundness?

Abstract
The recent consultative papers by the Basel Committee on Banking Supervision has raised the possibility of an explicit role for external rating agencies in the assessment of the credit risk of banks’ assets, including interbank claims. Any judgement on the merits of this proposal calls for an assessment of the information contained in credit ratings and its relationship to other publicly available information on the financial health of banks and borrowers. We assess this issue via an event study of rating change announcements by leading international rating agencies, focusing on rating changes for European banks for which data on bond and equity prices are available. We find little evidence of announcement effects on bond prices, which may reflect the lack of liquidity in bond markets in Europe during much of our sample period. For equity prices, we find strong effects of ratings changes, although some of our results may suffer from contamination by contemporaneous news events. We also test for pre-announcement and post-announcement effects, but find little evidence of either. Overall, our results suggest that ratings agencies may perform a useful role in summarizing and obtaining non-public information on banks and that monitoring of banks’ risk through bond holders appears to be relatively limited in Europe. The relatively weak monitoring by bondholders casts some doubt on the effectiveness of a subordinated debt requirement as a supervisory tool in the European context, at least until bond markets are more developed.

Private Equity in the Hospital Industry

Abstract
We examine employment and patient outcomes at hospitals acquired by private equity (PE) firms and PE-backed hospitals. While employment declines at PE-acquired hospitals, core medical workers (physicians, nurses, and pharmacists) increase significantly. The proportion of wages paid to core workers increases at PE-acquired hospitals whereas the proportion paid to administrative employees declines. These results are most pronounced for deals where the acquirers are publicly traded PE-backed hospitals. Non-PE-backed acquirers also cut employment but do not increase core workers or reduce administrative expenditures. Finally, PE-backed acquirers are not associated with worse patient satisfaction or mortality rates compared to their non-PE-backed counterparts.
