When Tariffs Disrupt Global Supply Chains 

Authors: Gene M. Grossman (Princeton University) and  Elhanan Helpman (Harvard University) 

Grossman and Helpman study unanticipated tariff on imports of intermediate goods in a setting with firm-to-firm supply relationships. Specifically, they study a setting where global supply chains are formed in anticipation of free trade, and, once they are in place, the home government surprises with an input tariff.

Gene M. Grossman is the Jacob Viner Professor of International Economics at Princeton University. Professor Grossman has received numerous professional honors and awards including the Onassis Prize in International Trade, the Harry G. Johnson Prize, the Bernard-Harms Prize and fellowships from the Sloan Foundation and the Guggenheim Memorial Foundation. He has done fundamental and path-breaking work in many areas of international economics. He is a Fellow of the Econometric Society and the American Academy of Arts & Sciences. He holds a PhD in Economics from MIT.
