Trade Within Multinational Boundaries

By: Laura Alfaro, Paola Conconi, Fariha Kamal and Zachary Kroff
We leverage newly linked data from the U.S. Census Bureau and the U.S. Bureau of Economic Analysis to study transactions within U.S. multinational enterprises (MNEs). We show that using administrative data on intrafirm trade allows us to correct for measurement error... View Details

Networks and the Macroeconomy: An Empirical Exploration

By: Daron Acemoglu, Ufuk Akcigit and William 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

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

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
