Capabilities and bipartite network structure. (A) We model the structure of Mcp by taking 2 random matrices representing the availability of capabilities in a country and the requirement of capabilities by products and consider that countries are able to produce products if they have all of the required capabilities. (B) The kc,0âkc,1 diagrams that emerge from 4 implementations of the model described in A. (C) kc,0 and kc,1 as a function of the number of capabilities (Nc) available in countries for 2 implementations of the model. (D) Average number of labor inputs required by products produced in a country as a function of the first 3 components of kâc.
