Quality of Management Control Information and its Public Disclosure to the Shareholders: an Empirical Evidence of its Usefulness from French Listed Companies
The relationships between events and investor actions, through changes in share prices and volumes, were largely studied in the literature. But two important variables have been omitted: the quality of the disclosure, prerequisite to usefulness of information, and the correlation of external and internal information (Management Control Information). This paper examines the impact of the Management Control Information public disclosure by firms to their shareholders. On the basis of existing literature in Management Control and Finance, and of expectations from regulatory bodies, two indexes of internal and external information quality are constructed, a typology is established, and four hypotheses are tested on a sample of 55 French listed companies. Parametric and non parametric tests are used to compare the impact on share prices and volumes traded on two samples created according to the quality of their disclosure. The results show that the higher the internal quality of information is, provided it is publicly disclosed, the more useful it is for the shareholders¿ decisions and actions. On the contrary, if internal information of lower quality is disclosed, it provides volatility on prices, showing investors¿ uncertainty.
