Financial Networks
Financial networks have been utilized in the study of financial systems since the work of Quesnay in 1758, who depicted the circular flow of funds in an economy as a network.
Quesnay's basic idea was subsequently applied in the construction of flow of funds accounts in matrix form.
The generality of the matrix tends to obscure certain structural aspects of the financial system that are of continuing interest in analysis, with the structural concepts of concern including those of financial intermediation.
