Using a novel survey of U.S. workers and a calibrated sector-choice model, we show that coworkers shape industry mobility through two offsetting channels: better information about wages and greater perceived access to jobs in connected sectors.

Using U.S. patent records matched to employer histories for four million inventors, we show that co-inventor ties to peers at firms specialized in other fields steer inventors into those fields. A mass-layoff displacement IV provides causal identification.

We study how coworker networks influence sectoral job-switching decisions, using German administrative data and causal identification strategies. A general equilibrium model highlights the role of coworker networks in labor reallocation and shows that considering these networks amplifies the trade-off between aggregate welfare and inequality.
