The decisions and productivity of individual workers often are influenced by peers—colleagues whom the individual works with or among, and who are similarly situated with respect to the stakes of production (e.g. Guryan, Kroft, and Notowidigdo, 2009; Battu, Belfield, and Sloane, 2003; Bruegmann and Jackson, 2009). This peer influence can arise in settings where production is explicitly collaborative, such as decisions by a corporate board or a performance by an orchestra; or settings where social norms and observed peer behavior pressure the individual toward expected choices, such as when productivity is openly comparable across individuals (Kandel and Lazear 1992, Mas and Morretti 2009).
