Network knowledge is key. AIPNET builds a production‑network graph via AI retrieval, revealing nodes like gallium that drive trade tensions. Knowing the graph lets policymakers target interventions precisely. For more: aipnet.io

if bargaining power shifts, quotas are better. You need to know the network. Network knowledge is the game changer. The paper shows that better maps of who is linked let policymakers pick the right tool—linear taxes, quotas, or nonlinear schemes—matching shock patterns.

Just read this paper that revisits Weitzman’s 1974 question on when policymakers should use taxes versus quotas to correct externalities in stochastic networked economies. It shows if shocks are positively correlated (like a global energy price jump) linear taxes win...

Today in economic complexity -- or, how we can use some techniques we are building to revolutionize how we can think about modern industrial policy. This time: how can animal bones serve as an input into vacuum pumps? There are many paths along a knowledge graph.
