Fig 1.
Diffusion cascades and cascade duration and size distributions.
Panel A: Heat map of all cascades in the sample, in the x-axis the cascade duration (the length of time that it takes to spread to its maximum geographic scope), and in the y-axis the cascade size (geographic scope). Panel B: The density distribution of the cascade duration. Panel C: The density distribution of the cascade size.

International cultural diffusion network.
Nodes represent countries and links the most likely cultural diffusion channels, taking as a proxy the estimated transmission rates. Node’s size indicates betweenness. Detected communities are depicted in different colors.

Panel A: Node network statistics correlations, including centrality measures and GDPpc. Panel B: Link level correlations, considering bilateral international trade and migration stocks, cultural and geographical distance. Cross-out signs imply not statistically significant correlations at a p-value of 0.01.
