Recent shocks such as US-China tariff increases and the COVID-19 pandemic rippled through global supply chains, and supply disruptions have been widely blamed for the return of inflation. Policymakers are also pushing manufacturing back home.

What they work on
- Model how occasionally binding capacity limits in supply chains shift domestic and import price Phillips Curves and fuel inflation, using a multisector open-economy New Keynesian model.
- Apply the capacity-constraint model to recent US data and determine the best monetary policy response to supply chain disruptions.
- Develop a framework in which risk-averse firms make sunk investments in a portfolio of capacity-limited suppliers, and study how these choices spread economic shocks.
- Assess whether trade and industrial policies can correct inefficient supply chain risk-taking and reduce aggregate economic volatility.
More about the research
This project asks how the details of how firms buy their inputs turn into risks for the whole economy. It focuses on capacity limits, investments that cannot be undone, and decisions made under uncertainty.
Why it matters
The work could help central banks and trade officials judge supply chain risks more accurately. It could guide how monetary policy should respond to disruptions such as those that fed recent inflation. It could also show whether reshoring, trade or industrial policies would actually reduce economic volatility.
Known grants
From NIH and NSF research grants. Labs often have other funding we can't see.
