Production Chains
Levine, David K. - 2010
More advanced technologies demand higher degrees of specialization - and longer chains of production connecting raw inputs to final outputs. Longer production chains are subject to a "weakest link" effect: they are more fragile and more prone to failure. Optimal chain length is determined by the...

Supply-Chain Trade : A Portrait of Global Patterns and Several Testable Hypotheses

Weathering the Storm : Supply Chains and Climate Risk
Castro-Vincenzi, Juanma; Khanna, Gaurav; Morales, Nicolas; … - National Bureau of Economic Research - 2024
We characterize how firms structure supply chains under climate risk. Using new data on the universe of firm-to-firm transactions from an Indian state, we show that firms diversify sourcing locations, and suppliers exposed to climate risk charge lower prices. Our event-study analysis finds that...

An Elementary Theory of Global Supply Chains
Costinot, Arnaud - 2011
This paper develops an elementary theory of global supply chains. We consider a world economy with an arbitrary number of countries, one factor of production, a continuum of intermediate goods, and one final good. Production of the final good is sequential and subject to mistakes. In the unique...

Supply Chain Risk : Changes in Supplier Composition and Vertical Integration
Ersahin, Nuri; Giannetti, Mariassunta; Huang, Ruidi - National Bureau of Economic Research - 2023
Using textual analysis of earnings conference calls, we quantify firms' supply chain risk and its sources. Our proxy for supply chain risk exhibits large cross-sectional and time-series variation that aligns with reasonable priors and is unprecedently high during the Covid-19 pandemic. In...

Supplier Churn and Growth : A Micro-to-Macro Analysis
Baqaee, David; Burstein, Ariel T.; Duprez, Cédric; … - National Bureau of Economic Research - 2023
We investigate the effects of input variety creation and destruction on both micro- and macroeconomic outcomes using detailed data from Belgium. We estimate that marginal costs rise by 0.6% for every 1% of suppliers lost. We show that this elasticity measures the area under the input demand...
