The Role of Global Supply Chains in the Transmission of Shocks: Firm-Level Evidence from the 2011 Tōhoku Earthquake
The April 2016 Kumamoto earthquake in southwest Japan has sent ripple effects through global supply chains. Toyota, Honda and Sony halted most Japanese production following the quake, and more recently General Motors announced production stoppages at four North American plants, citing parts shortages. Such far-reaching consequences of natural disasters are not without precedent.
Input Linkages and the Transmission of Shocks: Firm-Level Evidence from the 2011 Tohōku Earthquake
Using novel firm-level microdata and leveraging a natural experiment, this paper provides causal evidence for the role of trade and multinational firms in the cross-country transmission of shocks. Foreign multinational affiliates in the U.S. exhibit substantial intermediate input linkages with their source country. The scope for these linkages to generate cross-country spillovers in the domestic market depends on the elasticity of substitution with respect to other inputs. Using the 2011 Tohoku earthquake as an exogenous shock, we estimate this elasticity for those firms most reliant on ...
Monetary Policy and Durable Goods
We analyze monetary policy in a New Keynesian model with durable and nondurable goods each with a separate degree of price rigidity. The model behavior is governed by two New Keynesian Phillips Curves. If durable goods are sufficiently long-lived we obtain an intriguing variant of the well-known ?divine coincidence.? In our model, the output gap depends only on inflation in the durable goods sector. We then analyze the optimal Taylor rule for this economy. If the monetary authority wants to stabilize the aggregate output gap, it places much more emphasis on stabilizing durable goods inflation ...
