Econometric analysis of production networks with dominant units

Econometric Analysis of Production Networks with Dominant Units

This paper considers production and price networks with unobserved common factors, and derives an exact expression for the rate at which aggregate ‡uctuations vary with the dimension of the network. It introduces the notions of strongly and weakly dominant and non-dominant units, and shows that at most a …nite number of units in the network can be strongly dominant. The pervasiveness of a netwo...

Dominant Component Analysis of Electrophysiological Connectivity Networks

Connectivity matrices obtained from various modalities (DTI, MEG and fMRI) provide a unique insight into brain processes. Their high dimensionality necessitates the development of methods for population-based statistics, in the face of small sample sizes. In this paper, we present such a method applicable to functional connectivity networks, based on identifying the basis of dominant connectivi...

Production Networks as Communities of Autonomous Units and Their Stability

In this paper, discrete variants of production networks are considered as they can be encountered in the literature. On one hand, they are modeled as communities of autonomous units in the framework of graph transformation. On the other hand, a sufficient criterion for the stability of a production network is given where stability means that there exist suitable storage capacities at the produc...
