In this contribution, we introduce a network approach for the organization of global production across national borders, beyond the sequential industry-level metrics proposed in the previous literature. First, we show and argue that several characteristics of global production processes would be...

We introduce the Input Rank as a measure of relevance of direct and indirect suppliers in Global Value Chains. We conceive an intermediate input to be more relevant for a downstream buyer if a decrease in that input’s productivity affects that buyer more. In particular, in our framework, the...

We introduce a model of polarization in networks as a unifying setting for the measurement of polarization that covers a wide range of applications. We consider a substantially general setup for this purpose: node-and edge-weighted, undirected, and connected networks. We generalize the axiomatic...

In this contribution, at first, we introduce a basic network framework to study pyramidal structures and wedges between ownership and control of companies. Then, we apply it to a dataset of 53.5 million of companies operating in 208 countries. Among others, we detect a strong concentration of...
