• Production Networks: A Primer

  Annual Review of Economics · 2019-05-28 · 360 citations

  articleSenior author

  This article reviews the literature on production networks in macroeconomics. It presents the theoretical foundations for the role of input–output linkages as a shock propagation channel and as a mechanism for transforming microeconomic shocks into macroeconomic fluctuations. The article also provides a brief guide to the growing literature that explores these themes empirically and quantitatively.

• Information Sale and Competition

  Management Science · 2019-02-25 · 82 citations

  articleSenior author

  This paper studies the strategic interaction between a monopolistic seller of an information product and a set of potential buyers that compete in a downstream market. The setting is motivated by information markets in which (i) sellers have the ability to offer information products of different qualities and (ii) the information product provides potential buyers not only with more precise information about the fundamentals, but also with a coordination device that can be used in their strategic…

• Firms, Failures, and Fluctuations: The Macroeconomics of Supply Chain Disruptions

  National Bureau of Economic Research · 2020-07-01 · 59 citations

  reportOpen accessSenior authorCorresponding

  This paper studies how firm failures and the resulting disruptions to supply chains can amplify negative shocks. We develop a non-competitive model where customized supplier-customer relations increase productivity, and the relationship-specific surplus generated between firms and their suppliers is divided via bargaining. Changes in productivity alter the distribution of surplus throughout the economy and determine which firms are at the margin of failure. A firm's failure may spread to its sup…

• The Macroeconomics of Supply Chain Disruptions

  The Review of Economic Studies · 2024-04-08 · 55 citations

  articleSenior authorCorresponding

  Abstract This paper develops a model to study the macroeconomic implications of supply chain disruptions with three key ingredients: (i) a firm-level network of customized supplier–customer links that generate relationship-specific productivity gains; (ii) bargaining over these relationship-specific surpluses; and (iii) an extensive margin of adjustment, whereby firms decide to form or sever relations with suppliers and customers. We establish equilibrium existence and uniqueness, provide charac…

• Optimal Monetary Policy in Production Networks

  National Bureau of Economic Research · 2020-07-01 · 29 citations

  reportOpen accessSenior authorCorresponding

  This paper studies the optimal conduct of monetary policy in a multi-sector economy in which firms buy and sell intermediate goods over a production network. We first provide a necessary and sufficient condition for the monetary policy's ability to implement flexible-price equilibria in the presence of nominal rigidities and show that, generically, no monetary policy can implement the first-best allocation. We then characterize the constrained-efficient policy in terms of the economy's productio…
