Corporate Governance Berichterstattung als Instrument wertorientierter Unternehmensführung: Empirische Erkenntnisse für den deutschen Kapitalmarkt
Zusammenfassung
Der vorliegende Beitrag untersucht die Erfolgsrelevanz der Corporate Governance (CG) Berichterstattung bei 113 Gesellschaften im Prime Standard der Frankfurter Wertpapierbörse, welche den höchsten Transparenzstandards und der höchsten Analysten-Coverage unterliegen. Die Ergebnisse der simultanen Schätzung eines Mehrgleichungssystems, das Endogenität und reversible Kausalität berücksichtigt, weisen einen signifikant positiven Einfluss transparenter, freiwilliger CG Berichterstattung auf das Markt-Buchwert Verhältnis und die Aktienrentabilität nach. Ein theoretisch möglicher, reversibel kausaler Einfluss von Erfolgsindikatoren auf die CG Berichterstattung ist nicht festzustellen. Erstaunlicherweise kann für die deklarierte Umsetzung des Deutschen Corporate Governance Kodex (DCGK) keine signifikante Erfolgsrelevanz mehr nachgewiesen werden.

Abstract
This paper tests a simultaneous equation system on the relationship between corporate governance disclosure and firm performance for 113 German listed firms underlying the highest standards of transparency & disclosure of the Frankfurt Stock Exchange and receiving strongest analyst coverage. Capturing both mechanisms endogeneity and reverse causation, we provide evidence that there is a significantly positive relationship between voluntary corporate governance disclosure and market-to-book value and total shareholder return. Against theoretical assumptions, we couldn’t find evidence for reverse causation between firm performance and corporate governance disclosure. Surprisingly, we could not longer find evidence on a positive impact of declared compliance with the German Code of Corporate Governance on firm performance.
