Numerose ricerche empiriche dimostrano l’esistenza di una relazione positiva tra la qualità della corporate governance ed il valore dell’impresa. Nel presente lavoro, invece di focalizzarsi su un singolo meccanismo di governo societario, è stato utilizzato un Corporate Governance Index (CGI) multidimensionale composto da 41 variabili che possono essere suddivise in quattro diverse categorie: Board of Directors, Compensation, Shareholder’ Rights e Disclosure. Allo scopo di tenere in considerazione la potenziale natura endogena della relazione tra governo societario e firm value, è stato sviluppato un Modello di Equazioni Simultanee. Analizzando un campione di 99 imprese statunitensi incluse nel NYSE US 100 Index per il triennio 2012-2014, i risultati ottenuti supportano l’ipotesi ampiamente condivisa secondo cui la corporate governance, misurata dal CGI, influenza in maniera positiva e statisticamente significativa il valore dell’impresa, misurato dalla Tobin’s Q.

Abstract
Several empirical studies show evidence of a positive relationship between the quality of firm-specific corporate governance and firm value. In this research, instead of looking at one single corporate governance mechanism in isolation, it was used a multidimensional Corporate Governance Index (CGI) composed by 41 variables referable to four different dimensions: Board of Directors, Compensation, Shareholders’ Rights and Disclosure. To control for potential endogenous nature of the relationship between governance and value, it was developed a System of Simultaneous Equations. By analyzing a sample of 99 US firms included in the NYSE US 100 Index over three years (2012-2014), the results support the widespread hypothesis that corporate governance, as measured by CGI, has a positive and statistically significant influence on firm value, as measured by Tobin’s Q.| File | Dimensione | Formato | |
