We document considerable return comovement associated with accruals after controlling for other common factors. An accrual-based factor-mimicking portfolio has a Sharpe ratio of 0.16, higher than that of the market factor or the SMB and HML factors of Fama and French (1993). In time series...

In equilibrium disclosure is incomplete, and observers are unrealistically optimistic. Nevertheless,...

This paper presents some insights concerning qualitative and semi-quantitative audit risk assessment methods. We consider that semi-quantitative assessment collaborated with qualitative interpretation can be a better solution in evaluation auditors’ decisions. We then exemplify our solution by...

The current paper aims to study Web ontologies from a semiotic perspective. On the one hand, the study of signs is constantly used lately in the analysis of the social life, of organisations and informational systems. On the other hand, Web ontologies may be seen as systems of signs, wishing to...

It is crucial to design and implement decision support systems to assist the manager because of the diversity and the large amount of data stocked in an organization. The concept of decision support system (DSS) defines any information technology focused on supporting the decision process. For a...
