Adão, Arkolakis, and Esposito address this question by extending shift-share empirical designs to incorporate general equilibrium (GE) effects arising from spatial links between markets. Their motivation is that the difference-in-difference logic of standard shift-share regressions recovers only the differential response of treated versus control regions, not the level response that includes indirect (spillover) effects propagating through trade, labor supply, and agglomeration links. Ignoring these indirect effects biases estimates of trade shocks&rsquo; aggregate labor market consequences.</p>https://macropaperwarehouse.com/papers/input-sourcing-under-climate-risk-evidence-from-u.s.-manufacturing-firms/https://macropaperwarehouse.com/papers/input-sourcing-under-climate-risk-evidence-from-u.s.-manufacturing-firms/<p>Blaum, Esposito, and Heise study how supply chain risk — specifically, the risk of unexpected shipping delays caused by ocean weather conditions — affects U.S. manufacturing firms&rsquo; import sourcing decisions. The paper asks three related questions: Do weather-induced shipping delays harm firm performance? Do firms adapt their sourcing strategies ex ante in response to shipping time risk? And what are the aggregate welfare costs of heightened supply chain risk from climate change, geopolitical tensions, and port congestion?</p>
