Online MAP Enforcement: Evidence From a Quasi-Experiment

This paper investigates a manufacturer’s ability to influence compliance rates among its authorized online retailers by exploiting changes in the minimum advertised price (MAP) policy and in dealer agreements. MAP is a pricing policy widely used by manufacturers to influence prices set by their downstream partners. A MAP policy imposes a lower bound on advertised prices, subjecting violating retailers to punishments such as termination of distribution agreements. Despite this threat, violations are common.

The new policies lead to substantially fewer violations. With improved compliance, channel prices increase by 2% without loss in volume. The reduction in violations is particularly stark ...
