Matrices and Graphs : Theory and Applications to Economics - Proceedings of the Conferences, University of Brescia, Italy, 8 June 1993 and 22 June 1995

"This volume discusses applications on graphs to the analysis of both causal structure of econometric models and input/output matrices; the relationships between general linear models or covariance and graphical models; the characterization of irreducible matrices through graphs; computational matters of eigenvalues of non-negative and symmetrical matrices; qualitative analysis and the sign theorem; topics on the spectrum distribution for real matrices."--Publisher's website "Lonely Planet: The world's leading travel guide publisher"Lonely Planet The Italian Lakes is your passport to all the most relevant and up-to-date advice on what to see, what to skip, and what hidden discoveries await you.
