Literature, however, has yet to uncover how the promotions may complement each other when purposefully implemented. Our study examines this possibility in the grocery industry over three months. First, we create and manage a supermarket's Instagram profile, posting to the account (push promotion). Next, we compare performance measures with a third-party mobile app (pull promotion), which provides aggregated customer views and access to the supermarket profile. A time-series analysis reveals a sequential chain from push promotion to pull promotion to performance, the temporal effect of a push to pull, and the mediating effect from push to pull to purchase with an elasticity of .23. Results are important to those balancing push and pull promotional efforts and those involved with digital marketing and promotion in retailing. 收起
