Have we got news for you : theory and evidence on firms' optimal expected capacity utilization

Amberg, Niklas; Friberg, Richard; Liu, Xiang; Syverson, Chad - 2026

We use quarterly micro data on capacity utilization among Swedish manufacturing firms to show that idiosyncratic factors are more important than aggregate influences in explaining variation in capacity utilization across firms and over time. Idiosyncratic does not mean unpredictable, however. A...

The price of delay : supply chain disruptions and pricing dynamics

Baslandze, Salome; Fuchs, Simon - 2026 - Original version: August 2025, this version: March 2026

We study how supply chain disruptions shape consumer prices. We develop a simple model showing how disruptions that cause delivery delays affect pricing through product availability, beyond standard cost pass-through, and extend it to a setting with strategic interactions across firms....
