      Trade and Industrial Policy in Supply Chains: Directed Technological Change in Rare Earths

      By: Laura Alfaro, Harald Fadinger, Jay Schymik and Gede Virananda
      Trade and industrial policies, while primarily intended to support domestic industries, may unintentionally stimulate technological progress abroad. We document this mechanism in the case of rare earth elements (REEs)—critical inputs for manufacturing at the knowledge... View Details

      On the Direct and Indirect Real Effects of Credit Supply Shocks

      By: Laura Alfaro, Manuel García-Santana and Enrique Moral-Benito
      We explore the real effects of bank-lending shocks and how they permeate the economy through buyer-supplier linkages. We combine administrative data on all Spanish firms with a matched bank-firm-loan dataset of all corporate loans from 2003 to 2013 to estimate... View Details

      Networks and the Macroeconomy: An Empirical Exploration

      By: Daron Acemoglu, Ufuk Akcigit and William R. Kerr
      The propagation of macroeconomic shocks through input-output and geographic networks can be a powerful driver of macroeconomic fluctuations. We first exposit that in the presence of Cobb-Douglas production functions and consumer preferences, there is a specific pattern... View Details

      What Causes Industry Agglomeration? Evidence from Coagglomeration Patterns

      By: Glenn Ellison, Edward Glaeser and William R. Kerr
      Why do firms cluster near one another? We test Marshall's theories of industrial agglomeration by examining which industries locate near one another, or coagglomerate. We construct pairwise coagglomeration indices for US manufacturing industries from the Economic... View Details

      The Global Networks of Multinational Firms (with Maggie Chen)

      By: Laura Alfaro
      In this paper we characterize the topology of global multinational networks and examine the macro and micro patterns of multinational activity. We construct indices of network density at both pairwise industry and establishment level and measure agglomeration in a... View Details
