Theoretical and Methodological Approaches on the Intellectual Capital

The aim of this paper consists in providing a general overview of the notion of intellectual capital as a key to maximizing the corporate performance.

In terms of its measurement, we focus on a question which could be a solid base for the next studies: “Can intellectual capital be evaluated?” In this regard, a number of methods (direct and methods based on assets returns), generic model and individual company models were presented, concluding in this way with a hierarchy in terms of utility and their importance
