Join us for the Talk "Functional Structure in Production Networks", with Carolina Mattsson, next February 14th, 2022, at 11 am GMT, Lisbon, Portugal.
Carolina Mattsson is a Network Scientist developing the network analysis tools and modeling frameworks we need to study the economy as a complex system. Currently a Postdoc with the Computational Network Science group within LIACS at Leiden University, where I study real-world production networks, financial transaction networks, and temporal network representations.
Abstract: Production networks are integral to economic dynamics yet dis-aggregated network data on inter-firm trade is rarely collected and often proprietary. Here we situate company-level production networks within a wider space of networks that are different in nature, but similar in local connectivity structure. Through this lens, we study a regional and a national network of inferred trade relationships reconstructed from Dutch national economic statistics and re-interpret prior empirical findings. We find that company-level production networks have a so-called functional structure, as previously identified in protein-protein interaction (PPI) networks. Functional networks are distinctive in their over-representation of closed squares, which we quantify using an existing measure called spectral bipartivity. A shared local connectivity structure lets us ferry insights between domains. PPI networks are shaped by complementarity, rather than homophily, and we use multi-layer directed configuration models to show that this principle explains the emergence of functional structure in production networks. Companies are especially like their close competitors, not to their trading partners. Our findings have practical implications for the analysis of production networks and give us precise terms for the local structural features that may be key to understanding their routine function, failure, and growth.
This Talk is an initiative of the IT researcher Bruno Coutinho, from the Physics of Information and Quantum Technologies Group, supported by FCT/MCTES through national funds and when applicable co-funded EU funds under the project UIDB/50008/2020.
