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...

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...

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...

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...

The Supply Chain Economy: A New Industry Categorization for Understanding Innovation in Services
By: Mercedes Delgado and Karen G. Mills
An active debate has centered on the importance of manufacturing for driving innovation in the U.S. economy. This paper offers an alternative framework that focuses on the role of suppliers of goods and services (the “supply chain economy”) in national performance. We...
