This paper aims to test whether the publication of a social report provides information about the firm’s market value. We applied value-relevance analysis to the social reporting variable on a sample of 130 European listed banks, analysed from 2002 to 2008, to understand whether investors believe that the social report plays a role equivalent to that traditionally attributed to accounting variables. Our findings do not show a significant correlation between the publication of a social report and the stock price. We conclude that investors do not attribute a value-relevant to social report. However, cross-country analysis shows that national realities are very different. In some countries, the social report is seen as value-relevant and positively affects the stock price; in other countries, the social report remains value-relevant but negatively affects the stock price.
L’obiettivo della ricerca consiste nel verificare se il documento di bilancio sociale concorre a determinare il valore di mercato dell’azienda e, quindi, capire se gli investitori assegnano al bilancio sociale un ruolo simile a quello che tradizionalmente attribuiscono alle variabili contabili. L’indagine è stata sviluppata applicando la value- relevance analysis ad un campione di 130 banche europee osservate nel periodo 2002-2008. I risultati ottenuti per l’intero campione dimostrano che la relazione tra il valore di mercato dell’azienda e la variabile bilancio sociale non è significativa. Si potrebbe, quindi, concludere che gli investitori non attribuiscono al bilancio sociale un value-relevant. Tuttavia l’analisi cross-country evidenzia realtà nazionali molto diverse tra loro: l’effetto del bilancio sociale sul prezzo azionario si dimostra significativo, anche se positivo per alcuni Paesi e negativo per altri.

Abstract
This paper aims to test whether the publication of a social report provides information about the firm’s market value. We applied value-relevance analysis to the social reporting variable on a sample of 130 European listed banks, analysed from 2002 to 2008, to understand whether investors believe that the social report plays a role equivalent to that traditionally attributed to accounting variables. Our findings do not show a significant correlation between the publication of a social report and the stock price. We conclude that investors do not attribute a value-relevant to social report. However, cross-country analysis shows that national realities are very different. In some countries, the social report is seen as value-relevant and positively affects the stock price; in other countries, the social report remains value-relevant but negatively affects the stock price.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
