While much research has investigated peer effects in education, less is known about peer influence at work, particularly how bad peers affect other workers. I study soldiers during a time when the US Army granted large numbers of morality waivers to recruits with felony or misdemeanor convictions that normally preclude enlistment. I find that soldiers randomly assigned to larger shares of peers with criminal backgrounds are more likely to commit major misconduct. Additionally, that misconduct often occurs in the same month a waivered peer commits misconduct, suggesting that influence occurs through both exposure to adverse peers and their contemporaneous behavior.

Weak local labor market conditions may change the trajectories of young adults who expected to find work. Well-documented responses include increasing educational investments, moving to more prosperous labor markets, or reducing labor force attachment. Military enlistment is a channel of potential adjustment that has received less study. Using data on Army recruits, we demonstrate a significant local response in enlistment to mass layoffs, characterized by increased labor supply to the military rather than increased local military recruiting. Our work documents the significance of military employment as an important arm of adjustment to local labor market shocks.

We examine the effect of foreign employment on two outcomes—income shifting and the tax uncertainty of foreign transactions. Using a hand-collected sample of employment disclosures, we partition our sample into firm-years with a higher or lower degree of foreign employment. Using two distinct income shifting models, we document that, on average, a high degree of foreign employment is associated with greater tax-motivated income shifting out of the U.S. We also posit and find that a high degree of foreign employment enhances the economic substance of foreign transactions, reducing the tax uncertainty associated with foreign income. We conduct additional analyses to mitigate selection bias concerns, and we use exogenous changes to the costs and benefits of income shifting using foreign employment to strengthen identification. Our results highlight firms' use of employees as part of a tax-efficient supply chain and how foreign employment enhances income shifting opportunities between jurisdictions.
