Supply networks are complex interorganizational systems in which structural prominence may have different associations with operational and financial outcomes. We examine 169 firm-year observations from 38 focal firms in 10 industries. The primary three-knot restricted cubic-spline models include industry and year indi...
Global trade is more than a single network of aggregate flows. Beneath the observable exchange of products among economies lies a complex multilayer structure, formed by thousands of product-specific trade relationships that differ in their similarity, interdependence, and temporal evolution. Using the CEPII's BACI dat...
Dynamic and multilayer networks have been widely studied separately, but their joint analysis remains comparatively underdeveloped. Because the relational information of a dynamic multilayer network can be represented as a tensor at each time point $t$, each layer can be summarized through a set of structural statistic...
Gravity models constitute the workhorse of empirical international trade research, yet the temporal stability of their core parameters—distance and GDP elasticities—remains underexplored, particularly in relation to the evolving structure of trade networks. This study investigates the bidirectional Granger‐causal rel...
